Description

  The present invention relates to a knowledge propagation tracking information recording apparatus, a knowledge propagation tracking information recording method, and a program for recording tracking information of knowledge propagation from person to person performed in the real world and an information system.

  Knowledge distribution is considered to be performed by repeating the process of knowledge transmission from a knowledge provider → knowledge reference by a knowledge user → knowledge interpretation by a knowledge user → knowledge re-transmission from a knowledge user. The knowledge propagation tracking information record in the present invention is a process of “knowledge transmission from a knowledge provider → re-transmission of knowledge from a knowledge user”. For knowledge, knowledge transmission by a knowledge provider → knowledge reference by a knowledge user In this process, the knowledge is transferred from the provider to the user, and the knowledge user interprets the knowledge and then detects and records whether or not the knowledge re-presentation is performed.

Knowledge refers mainly to information expressed in language, but can also include information on art, music, theater, photography and movies. Here, as contents of knowledge transmission,
(1) When the knowledge itself is transmitted directly (the transmission method in this case is directly transmitted, and the knowledge transmitted in this case is called direct knowledge)
(2) Indirect information for referring to knowledge, for example, URL (Uniform Resource Locator), book name, file name, event name, etc. Knowledge is called indirect knowledge)
It is roughly divided into two.

Furthermore, as media used for knowledge dissemination and knowledge reference,
(A) When using a digitized information system (e-mail, electronic bulletin board, wiki, various information sharing systems, etc.)
(B) When using real-world media (oral presentation, presentation by exchanging things (books, papers, etc.), transmission by guiding to places and events)
It is divided roughly into.

  Here, knowledge propagation is a process of “transmission of knowledge from knowledge provider” → “reference of knowledge by knowledge user” → “knowledge interpretation by knowledge user” → “re-transmission of knowledge from knowledge user”. It is thought that it is done by repetition. Tracking the flow of knowledge in this knowledge propagation process from the present to the past is called “knowledge traceability”.

  With regard to the realization of knowledge traceability, knowledge traceability can be realized by technologies that analyze the contents of e-mails and records of sent and received logs, and the contents and access records of the Web and various information sharing systems. Is possible.

And a knowledge reference unit 3 and a knowledge retransmitting unit 5.

  The knowledge transmission analysis unit 2 detects the transmission knowledge 101 and generates information (knowledge transmission information 102) indicating that specific knowledge is transmitted from the knowledge provider. The knowledge reference analysis unit 4 detects information (knowledge reference information 104) indicating whether or not the knowledge is referred to by the knowledge user including the case where the knowledge is indirectly transmitted.

  The knowledge re-transmission analysis unit 6, when the person (knowledge user) who referred to the knowledge transmits the knowledge 105 using the knowledge re-transmission unit 5, the knowledge 105 refers to the knowledge (reference) that the knowledge user referred to in the past. It is determined whether or not the information is transmitted in relation to the knowledge 103). If the knowledge 105 is transmitted in relation to the past reference knowledge 103, it is assumed that the knowledge has propagated, and information indicating the knowledge propagation is output as the knowledge propagation information 106. The knowledge tracking information storage unit 7 stores the calculated knowledge propagation information 106.

  The knowledge transmitter 1 is a means for a knowledge provider to transmit knowledge. The knowledge reference unit 3 and the knowledge re-transmission unit 5 are means for a knowledge user to refer to knowledge and to transmit knowledge related thereto. The knowledge transmitter 1 transmits knowledge that can be directly perceived by a person, such as a speaker that outputs a voice of the person, a voice through a telephone line, a paper or a white board on which characters or pictures are written, or the like. The displayed display device is applicable. Media for transmitting knowledge expressed in electronic data includes a network, a computer connected to the network, and a data transmission program that operates on the network, such as an e-mail or a data registration program.

  The knowledge reference unit 3 is a human sense for knowledge transmitted by an expression method that can be directly perceived by a person. For knowledge transmitted through electronic media, a network, a computer connected to the network, and a data receiving program that operates on the network, such as e-mail, a data search program, or a browser. The knowledge retransmitting unit 5 has the same configuration as the knowledge transmitting unit 1.

  FIG. 2 is a block diagram illustrating a configuration example of the knowledge transmission analysis unit 2 according to the embodiment. The knowledge transmission analysis unit 2 detects transmission of information corresponding to knowledge from information transmitted through various media, and extracts the result as knowledge transmission information 102.

  The types of media used in knowledge propagation include knowledge propagation when a physical object (such as a book or CD-ROM), which is an information recording medium, is handed over from person to person, and voice (sign language) in a person-to-person conversation. Knowledge transmission by writing, or knowledge propagation by referring to information that is transmitted by an information provider to a specific file or a specific Web page on the information system. There are two types of timing of knowledge propagation: when knowledge transmission and knowledge reference are performed simultaneously, and when knowledge reference is performed after a certain time has elapsed since knowledge transmission was performed. The knowledge transmission analysis unit 2 in FIG. 2 shows a configuration example in the case of realizing a total of six knowledge propagation tracking information records, which combines the use medium and timing of knowledge propagation.

  FIG. 3 shows an example of the knowledge transmission information 102. The knowledge transmission information 102 is information obtained by extracting and recording information sufficient for specifying where the knowledge user refers to some knowledge later when the knowledge user transmits the knowledge. Representative components of the knowledge transmission information 102 include information for identifying the person who transmitted the knowledge (sender ID), information for specifying the position where the knowledge is transmitted (transmission position), and the time of transmission (transmission) (Time), information for distinguishing the used media in detail (medium detail type), and an information list having a combination of knowledge contents as one record. Here, as the “sending location” information, when the media to be used is real world media, for example, the latitude and longitude, information for distinguishing buildings (building ID), and the location in the real world such as the three-dimensional coordinates in the building are used. Information that can be identified. When the use medium is an information system, for example, a path name of a file in which knowledge is stored, a URL (Uniform Resource Locator) indicating a Web page in which the knowledge is described, data that can specify an information position on the information system, To do.

  The knowledge transmission analysis unit 2 includes, for example, an object possession detection unit 21, a human position detection unit 22, a voice input unit 23, a voice analysis unit 25, an information system operation recording unit 24, and an information system operation analysis unit 26. And a knowledge transmission extracting unit 27.

  The object possession detection unit 21, the human position detection unit 22, the voice input unit 23, and the voice analysis unit 25 are means for analyzing real world media. The information system operation recording unit 24 and the information system operation analysis unit 26 are means for analyzing the information system.

  The object possession detection unit 21 detects that a person is carrying a physical object (for example, a book or a CD-ROM) in the real world. The person position detector 22 detects person position information in the real world. The voice input unit 23 acquires voice uttered by a person in the real world. The voice analysis unit 25 extracts keywords included in the voice from the voice by so-called voice recognition technology.

  The information system operation recording unit 24 records operation information of an information provider on the information system such as transmission of e-mail, file editing, and information transmission on the Web. The information system operation analysis unit 26 extracts from the operation information recorded by the information system operation recording unit 24 when, where, and what information was transmitted by a technique such as so-called log analysis or text analysis. To do.

  The knowledge transmission extraction unit 27 covers from the outputs of the object possession detection unit 21, the human position detection unit 22, the voice analysis unit 25, and the information system operation analysis unit 26, "when and where by what knowledge" was transmitted. To extract.

  As for the human position detection unit 22, first, as a basic function thereof, GPS (Global Positioning System), RFID (Radio Frequency IDentification), which are widely known as conventional techniques capable of acquiring the position of a designated person, are used. ), Ultrasonic tag (for example, AIST TODAY 2005-08, pages 26-27), infrared tag device (for example, “Indoor high-precision positioning service platform SmartLocator” NEC Technical Report Vol.58, No.3, pages 2) A technology such as a wireless LAN terminal (for example, “Presence Service Using Wireless LAN Positioning” NEC Technical Report Vol. 58, No. 3, page 101) can be used alone or in combination.

  An ID of a device (GPS terminal, RFID tag, ultrasonic tag, infrared tag, wireless LAN terminal) to be given to a person is associated with a code for identifying the person in advance. Then, using these technologies, the position information of the device held by the person is continuously acquired, the time information at which the position information is acquired is given to each position information, and further the transmission for identifying the person in the position information By combining the person ID, it is possible to carry out human position detection necessary for the present invention.

  The object possession detection unit 21 is means for detecting that a person possesses a physical object including knowledge such as a book, and can use a conventional technique similar to the human position detection unit 22. For example, in order to detect a person's position in human position detection, a device similar to an RFID or ultrasonic tag attached to a person is also attached to a physical object, and whether or not the person and the physical object exist at the same time and at the same position. Determine. If it exists at the same position at the same time, it can be carried out by determining that the person possesses the physical object. Furthermore, after the detection at the same time and at the same position, it is determined that the person possesses the physical object only when the physical object position similarly changes when the position of the person changes. The method is more effective as a method for more reliably determining what a person has.

  The voice input unit 23 and the voice analysis unit 25 are means for detecting that a person has spoken a word or phrase corresponding to direct knowledge or indirect knowledge. The voice input unit 23 and the voice analysis unit 25 are integrated with the detection result of the person position detection unit 22. Thus, it is detected who and where the word is spoken.

  The voice input unit 23 is a method of inputting voice in real time by voice input, such as microphones distributed on the ceiling of the room, or a wireless microphone that can be carried by a person. It is possible to implement the method (offline processing) in which the start time is recorded at the same time as recording, and the audio data and start time information recorded after a lapse of a certain time are input to the present apparatus.

  Here, for example, when using voice input means whose positions are fixed like microphones distributed on the ceiling, the knowledge transmission position can be used by regarding the installation location information of each microphone as the utterance position. Furthermore, it is possible to identify the person who made the utterance by associating the microphone location information with the position information of the person obtained as the detection result of the person position detection unit 22.

  For example, when a mobile voice input unit capable of real-time processing such as a wireless microphone is used, it is possible to identify a speech and a person by previously associating the voice input unit with a person. As for the utterance position, the position can be specified by the integration process with the human position detection unit 22.

  Further, when using offline processing and mobile voice input means such as a portable voice recorder, the person can be specified by associating the voice input means and the person in advance in the same manner as the wireless microphone. . On the other hand, regarding the specification of the utterance position, it is possible to specify the utterance position by calculating the time when each utterance was performed based on the information of the start time and associating with the detection of the human position detection unit 22 based on the time information. Is possible.

The voice analysis unit 25 detects the utterance content, the utterer, the utterance time, and the utterance position when the obtained voice information includes a phrase that may correspond to knowledge. Here, the center of the process of the voice analysis unit 25 is a process of detecting an utterance that may correspond to knowledge. About this process
(1) When a keyword representing knowledge to be recorded in knowledge propagation tracking information is known in advance and used as a dictionary for speech recognition (detection method 1)
(2) When speech recognition is performed using a general method, and the resulting phrase is cut out in a specific format indicating knowledge (detection method 2)
(3) When speech recognition is performed using a general method, and an appearance pattern such as a particular word or phrase protruding in a certain time range is characteristic (detection method 3)
This is effective.

  As for the detection method 1, for example, a method using a specialized term dictionary in a specialized area as a dictionary indicating direct knowledge, or a method using a room name, a shelf name, an address, an event name, etc. indicating a position as a dictionary indicating indirect knowledge as a dictionary. It can be implemented.

  For detection method 2, for example, a method for detecting file path expressions (such as starting with “C:”) or URL expressions (starting with “http: //”) that are likely to appear as indirect knowledge by pattern matching. Can be implemented.

  The information system operation recording unit 24 and the information system operation analysis unit 26 are means for detecting that direct knowledge or indirect knowledge has been transmitted to the information system. The transmitted content (transmission knowledge), sender ID The purpose is to detect the transmission time and the transmission location (position on the information system).

  The information system operation recording unit 24 is means for recording information provider operations on the information system, such as transmission of electronic mail, writing to a file, and transmission of information on the Web for the purpose.

Recording the operation of the information provider on the information system can be performed, for example, by the following method.
-A method of recording operation logs of information providers that pass through e-mail servers, http proxy servers, routers, etc.
-On the terminal used by the information provider to send information,
(I) For example, if the operating system of the terminal is Windows (registered trademark) of Microsoft Corporation, the key operation and mouse operation are logged by the so-called API hook technology, and at the same time, a low-level (driver level) file I generated A method of implementing a module that records / O information (target file path name and open / close event) as a filter driver.
(Ii) For example, if the operating system is Linux distributed with open source, logging to record file I / O information in the file system as well as logging key operations and mouse operations using the XWindow server function How to embed functionality.
(Iii) For example, if the operating system of the terminal is Microsoft Windows (registered trademark), the screen drawing information is acquired by Microsoft Active Accessibility Technology, etc., and if the terminal is Linux by monitoring the XWindow protocol, etc. A method for detecting a text character string included in information by analyzing a text drawing command in the information as information that may be relevant to knowledge.
(Iv) For example, a screen display image is acquired as image data by a so-called screen capture function in a terminal, and the character string displayed on the screen is analyzed by analyzing the image data by so-called OCR (Optical Character Recognition) software. A method of detecting information that may be relevant to knowledge.

  The information system operation analysis unit 26 is means for analyzing the operation information detected by the information system operation recording unit 24 and extracting information that may correspond to knowledge from the analysis. For example, in the case where the medium is an electronic mail, the act of sending a mail by a knowledge provider is regarded as knowledge transmission. Here, it is considered that the destination address detected by analyzing the mail header is the knowledge transmission position, and the mail subject or the body is decomposed into words by morphological analysis to analyze information that may correspond to knowledge. A method of detecting and using the information as transmission knowledge is possible.

In this case, as a method of detecting information that may be relevant to knowledge,
(4) A method of performing matching with a word extracted using the dictionary as a dictionary (detection method 4) when knowledge to be recorded for propagation tracking information is known in advance.
(5) A method of cutting out the word / phrase of the obtained word / phrase in a specific format indicating knowledge (detection method 5),
(6) A method of cutting out an appearance pattern that is characteristic such that the frequency of occurrence of a specific phrase protrudes in a certain time range (detection method 6)
This is effective.

  As for the detection method 4, for example, a method using a specialized term dictionary in a specialized area as a dictionary showing direct knowledge, or a method using a room name, a shelf name, an address, an event name, etc. indicating a position as a dictionary showing indirect knowledge as a dictionary. It can be implemented.

  As for the detection method 5, for example, a method for detecting file path expressions (for example, starting with “C:”) or URL expressions (starting with “http: //”) that are likely to appear as indirect knowledge by pattern matching. Can be implemented.

  The knowledge transmission extracting unit 27 obtains information related to knowledge transmission via the real object obtained from the object possession detection unit 21 and the human position detection unit 22, and the voice input unit 23, the voice analysis unit 25, and the human position detection unit 22. The information related to knowledge transmission by voice and the information related to knowledge transmission on the information system obtained from the information system operation recording unit 24 and the information system operation analysis unit 26 are tabulated, for example, in a table format as shown in FIG. This can be implemented by outputting as information.

  FIG. 4 is a block diagram illustrating a configuration example of the knowledge reference analysis unit 4 according to the embodiment. The knowledge reference analysis unit 4 is a means for detecting that a knowledge user has referred to each piece of knowledge extracted as the knowledge transmission information 102. The knowledge reference analysis unit 4 includes a human position detection unit 51, an information system reference operation recording unit 52, an information system reference operation analysis unit 53, and a knowledge reference determination unit 54.

  The person position detection unit 51 detects position information of a person in the real world. The information system reference operation recording unit 52 records operation information of an information user on the information system such as reception of e-mail, file editing, information reference on the Web, and the like. The information system reference operation analysis unit 53 detects that the user has referred to the knowledge from the logging information by a technique such as so-called log analysis or text analysis.

  The knowledge reference determination unit 54 aggregates the results obtained from the human position detection unit 51 and the information system reference operation analysis unit 53 and outputs the result as knowledge reference information 104.

  From the relationship between the knowledge transmission position and knowledge transmission time in the knowledge transmission information 102 and the knowledge reference position and knowledge reference time obtained by analyzing the reference knowledge 103 referred to by the knowledge user, the knowledge reference analysis unit 4 It is determined whether or not the knowledge user has referred to the knowledge indicated by each record of the knowledge transmission information 102. Then, information for specifying the knowledge determined to have been referred to is extracted as knowledge reference information 104. Here, FIG. 6 shows an example of the knowledge reference information 104. If the reference knowledge 103 is a “causal extraction method based on co-occurrence”, the contents of the knowledge transmission information 102 shown in FIG. This example shows that the corresponding record is extracted as knowledge reference information 104.

  The human position detector 51 detects the knowledge reference position information 108 in the same manner as the human position detector 22. Here, the knowledge reference position information 108 is provided with the content of the referred knowledge, the time when the reference was made, and a user ID for identifying the knowledge user who made the reference.

  The information system reference operation recording unit 52 and the information system reference operation analysis unit 53 are means for detecting that the information user has referred to direct knowledge or indirect knowledge on the information system. It is an object to detect a reference person, a reference time, and a reference place (position on the information system) and transmit the detected information as information system reference information 109 to the knowledge reference determination unit 54.

  The information system reference operation recording unit 52 records information user reference operation information on the information system, such as reception of e-mail, reading of a file, reference of information on the Web, and the like. The information system reference operation recording unit 52 can be implemented by the same technique as the information system operation recording unit 24.

  The information system reference operation analysis unit 53 refers to when, who, where and what information from the reference operation information recorded by the information system reference operation recording unit 52 by a technique such as so-called log analysis or text analysis. To extract.

  The information system reference operation analysis unit 53 is means for analyzing the reference operation information recorded by the information system reference operation recording unit 52 and extracting information that may correspond to knowledge reference from the analysis. For example, in the case where the media is e-mail, the knowledge user may regard the act of reading the e-mail as a knowledge reference operation, and further decompose the e-mail subject and body into words by morphological analysis and analyze it. It can be implemented by detecting certain information and regarding the information as reference knowledge. In this case, as a method for detecting information that may correspond to knowledge, the same detection method 4 (detection method 5), (detection method 6) as the information system operation analysis unit 26 should be performed. Is possible.

  The knowledge reference determination unit 54 determines whether or not the transmitted knowledge indicated by each record of the knowledge transmission information 102 shown in FIG. 3 matches the knowledge (reference knowledge 103) referred to by the knowledge user. It is a means for judging. If there is a match, the reference ID indicating who the reference is, the reference position, the reference time, the detailed information of the used media, and the knowledge content are shown in FIG. The knowledge reference information 104 is sent to the knowledge re-transmission analysis unit 6.

  Here, when the media used in the record of the knowledge transmission information 102 is real world media, the determination is made using the knowledge reference position information 108 sent from the human position detection unit 51. The determination is made using the information system reference information 109 sent from the information system reference operation analysis unit 53. Judgment when the media used is real-world media can be performed by the following procedure.

  The knowledge content in the knowledge transmission information 102 matches the reference knowledge indicated by the knowledge reference position information 108, and the knowledge transmission time in the knowledge transmission information 102 and the knowledge reference time given to the knowledge reference position information 108 are the same time, and When the knowledge transmission position in the knowledge transmission information 102 and the knowledge reference position given to the knowledge reference position information 108 are the same point, it is determined that the knowledge indicated by the record of the knowledge transmission information 102 is referred to by the knowledge user Can do. Here, the “same location” means that the knowledge transmission position and the knowledge reference position are not only when the position information is completely matched but also when it is close enough that it can be considered that the person has come into contact with the person in the real world. It is effective to determine that it is regarded as “the same point”.

  “Same time” means that knowledge is delivered in a situation where the knowledge provider and the knowledge user face each other in the real world. Therefore, “same time” means not only when the times are exactly the same, but also at a short enough interval that knowledge transmission and knowledge reference can be regarded as being performed continuously in a person-to-person environment. In the case where it is shown that the knowledge reference order is performed, it is effective to determine the knowledge transmission time and the knowledge reference time as “same time”.

  Furthermore, if the media used is a physical object in the real world media, that is, in the real world, for example, after a knowledge provider places the book at a certain location, the knowledge user contacts the book at that location after a certain period of time. In this case, if the target media is a physical object in the real-world media, the knowledge reference time is transmitted without limiting the time-related condition to “same time”. It is effective to relax and determine the condition “after knowledge transmission time in information 102”.

  The determination when the media used is other than the real world media (that is, the information system) can be performed by the following procedure. The knowledge content in the knowledge transmission information 102 matches the reference knowledge indicated by the information system reference information 109, and the knowledge reference time given to the information system reference information 109 is a time after the knowledge transmission time in the knowledge transmission information 102, Furthermore, when the knowledge transmission position in the knowledge transmission information 102 and the knowledge reference position given to the information system reference information 109 are the same point, it is determined that the knowledge user has referred to the knowledge indicated by the record of the knowledge transmission information 102 can do.

  FIG. 5 shows a configuration example of the knowledge retransmission analysis unit 6 according to the embodiment. The knowledge re-transmission analysis unit 6 is a means for the knowledge user to detect the knowledge itself after the knowledge reference or knowledge re-transmission after interpreting the knowledge. FIG. 5 shows an example of implementation in which a knowledge user who has received indirect knowledge as an “interpretation” by a knowledge user can track the propagation of the knowledge when the knowledge user replaces the knowledge with the related direct knowledge. Show.

  In the knowledge re-transmission analysis unit 6 in FIG. 5, each means of the object possession detection unit 59, the human position detection unit 60, the voice input unit 57, the voice analysis unit 58, the information system operation recording unit 61, and the information system operation analysis unit 62. Can be implemented by the same configuration as each means shown in FIG.

  In addition to this, the knowledge retransmission analysis unit 6 includes a direct indirect determination unit 56, an indirect knowledge analysis unit 55, and a knowledge retransmission determination unit 63.

  The direct indirect determination unit 56 is a means for determining whether or not the knowledge reference information 104 can be indirect knowledge.

  As the implementation of the determination process, for example, a room name, a shelf name, an address, an event name, a building name, etc., where the knowledge content of the knowledge reference information 104 can be a word that may indicate the location of other knowledge, is used as a dictionary. Prepare in advance and check whether the knowledge includes these words or not. As another embodiment, for example, a file path expression (for example, starting with “C:”) or a URL expression (starting with “http: //”) indicating a position on the information system is detected by pattern matching. It is possible to use the method to do. The direct / indirect determination unit 56 outputs the result as an indirect knowledge determination result 110 to the indirect knowledge analysis unit 55.

  As another example, when the content of the knowledge reference information 104 is a book name, it is also effective to determine that the book name can be indirect knowledge with respect to the knowledge described therein. Further, when it is determined that the knowledge can be indirect, and there are a plurality of direct knowledge corresponding to the knowledge, it is also effective to store a plurality of values as direct knowledge contents.

  If the indirect knowledge determination result 110 is “can be indirect knowledge”, the indirect knowledge analysis unit 55 adds the direct knowledge indicated by the indirect knowledge to the knowledge reference information 104 and has already determined indirect knowledge. Output as information 107. FIG. 7 shows an example of the indirect knowledge determined information 107.

  If it is not determined that “it can be indirect knowledge”, the content of the knowledge reference information 104 is transferred to the corresponding field of the indirect knowledge determined information 107, and the direct knowledge content field that does not exist in the knowledge reference information 104 is blank. The indirect knowledge determined information 107 is generated.

  When it is determined that “it can be indirect knowledge”, based on the indirect knowledge given as input, direct knowledge referred to by the indirect knowledge is also acquired. For example, when the knowledge input as the knowledge reference information 104 is information indicating a URL, the indirect knowledge analysis unit 55 accesses the information source indicated by the URL, and the knowledge described therein is related to the direct knowledge. Get as.

  The knowledge re-transmission determination unit 63 determines whether the knowledge is re-transmitted as it is or after interpreting the knowledge received from another knowledge provider when the knowledge user transmits the knowledge. It is means of. Here, interpretation means making indirect knowledge direct knowledge.

  If it has been retransmitted, it is considered that the knowledge has been propagated, and information related to the propagation (sender ID, referrer ID, transmission position, retransmission position, transmission time, reference time, retransmission time, media details) The information shown in FIG. 8 is sent to the knowledge tracking information storage unit 7 as knowledge propagation information 106 and recorded.

  The determination of retransmission in the knowledge retransmission determination unit 63 can be performed by the following processing.

  First, the knowledge retransmission determination unit 63 stores all the indirect knowledge determined information 107 received before that time. Here, when the knowledge user transmits some knowledge 105, the result of analyzing the content (knowledge content, knowledge transmission position, knowledge transmission time, media detailed type, etc.) is the object possession detection unit 59, human position detection unit. 60, and is transmitted to the knowledge retransmission determination unit 63 via any one of the voice analysis unit 58 and the information system operation analysis unit 62. At this time, the knowledge re-transmission determination unit 63 determines whether or not a match with the knowledge content exists in the knowledge content field or the direct knowledge content field of the accumulated indirect knowledge determined information 107. Can be implemented by regarding it as a re-transmission of the knowledge. Here, the knowledge content of the knowledge 105 is stored in the retransmitted knowledge content of the knowledge propagation information 106. When knowledge propagates without interpretation by a knowledge user, the knowledge content of the knowledge 105, the knowledge propagation information 106, and the retransmitted knowledge content all have the same value.

  On the other hand, when it is propagated after being interpreted by the knowledge user, the knowledge 105 has the same value as the retransmitted knowledge content of the knowledge propagation information 106, and the knowledge content of the knowledge propagation information 106 is the knowledge before interpretation, that is, Indirect knowledge is stored. FIG. 8 shows an example of the contents of the knowledge propagation information 106 when interpretation is performed. In other words, after that, it is possible to know whether or not interpretation has been performed in the process of knowledge propagation by comparing the knowledge content of the knowledge propagation information 106 and the retransmitted knowledge content.

  The knowledge tracking information storage unit 7 stores the knowledge propagation information 106 shown in FIG. 8 obtained as a result of the analysis.

In some cases, the acquired knowledge is regarded as knowledge transmitted by the knowledge transmitting unit 1, and the knowledge reference and knowledge re-transmission are further performed. In this case, the knowledge propagation tracking information recording device repeatedly performs knowledge transmission analysis, knowledge reference analysis, and knowledge retransmission analysis, and detects and records the knowledge reference and knowledge retransmission chain as knowledge propagation information 106.

  Note that the number of retransmission knowledge is not limited to one for one knowledge, and there may be a plurality of retransmission knowledge for one knowledge. Further, the referred knowledge and the retransmitted knowledge are not necessarily adjacent to each other in time series in the transmitted knowledge group. It is also possible to detect the relationship between knowledge references and knowledge re-transmissions that are separated in time, and in this case, knowledge propagation information is recorded by regarding the relationship as knowledge propagation.
