Description

  The present invention relates to an electronic file management apparatus, method, and program for assigning behavior information corresponding to an electronic file as a tag using user life log information.

  In recent years, portable terminals such as mobile phones, smart phones, PDAs (Personal Digital Assistants), and notebook personal computers have been equipped with various sensors and increased memory capacity, so that photo files, memo writing (text) files, etc. Various electronic files can be created and stored. However, if the electronic file is stored by itself, it takes time and labor to retrieve the desired electronic file later.

  In view of this, it has been considered that information on actions related to an electronic file is given as a tag. For example, Non-Patent Document 1 describes a method of associating a plurality of information sources by calculating the degree of coincidence of the time zone indicated by the time information using the time information given to each information source as a key. Has been.

  However, the creation or input time of the electronic file and the action time zone indicated by the action information given as a tag are not always the same. For example, when you want to add behavior information “wedding” as a tag to an electronic file such as a photo related to a certain “wedding”, not only the time when “wedding” was held, but also the time before and after that time. Users who want to add a “wedding” tag to electronic files created or entered in the band, such as photos taken at the wedding party route or after the second party after the wedding. Is supposed to think. However, since the technique described in Non-Patent Document 1 performs the process of associating information by focusing only on the degree of coincidence of the time information given to the information source, it can respond to the request as described above. Can not.

  The present invention has been made paying attention to the above circumstances, and the object of the present invention is to create an electronic file even when the creation time or input time of the electronic file is different from the execution time of the behavior information related to the electronic file. An object of the present invention is to provide an electronic file management apparatus, method, and program that can appropriately assign the related behavior information as a tag.

Then, based on the read stay place information, the target period is classified into a first period in which the user exists in the base stay place and a second period in which the user exists in a stay place other than the base place. It is determined whether the input electronic file creation or input time is included in the classified first period or second period. Then, the behavior information executed during the first or second period determined to include the creation time or input time of the electronic file is read from the behavior information database storing the user behavior information, and this read The behavior information is stored in association with the electronic file as a tag.

  Therefore, according to the 1st viewpoint of this invention, the action information provided to an electronic file can be narrowed down using the information on the stay place used as a user's base, and the stay period. As a result, even when an electronic file related to the behavior information is created or input at a time different from the execution time of the behavior information, the related behavior information can be appropriately given to the electronic file as a tag. It becomes. As a result, it is possible to accurately manage electronic files based on the user's own action history, and it is possible to efficiently search for a target electronic file even when the number of electronic files increases.

Then, the action information having the smallest calculated time difference is selected, and the selected action information is associated with the electronic file as a tag.
In this way, even when there are a plurality of action information executed in the first or second period, the action information whose execution time is closest to the creation or input time of the electronic file is selected, and the electronic file is used as a tag. It becomes possible to grant.

In the second aspect, when information indicating the importance is added to the behavior information, the importance is highest based on the information indicating the importance among the plurality of read behavior information. Action information is selected, and the selected action information is associated with the electronic file as a tag.

  In order to achieve the above object, according to a second aspect of the present invention, an electronic file created by a user in relation to his / her behavior is input together with information indicating the creation or input time, and the input electronic file The action information executed during the period including the creation or input time is read from the action information database storing the action information of the user. Then, the similarity between the content of the input electronic file and the action content of the read action information is calculated, action information whose calculated similarity is equal to or greater than a threshold is selected, and the selected action information is The electronic file is associated as a tag.

  Therefore, according to the second aspect, action information whose similarity with the content of the electronic file is greater than or equal to a threshold value is selected from a plurality of action information, and this is given to the electronic file as a tag. For this reason, even when an electronic file related to the behavior information is created or input at a time different from the execution time of the behavior information, the related behavior information can be appropriately given to the electronic file as a tag. Become. Therefore, in this case as well, it is possible to accurately manage electronic files based on the user's own action history, and even when the number of electronic files increases, it is possible to efficiently search for the target electronic file.

The second processing unit 2 and other database groups and interface groups are provided.

  As other database groups, a behavior information database 31, an electronic file / behavior information storage unit 33, and a tagged electronic file database 34 are prepared. An electronic file input receiving unit 32 is prepared as another interface group.

  The behavior information database 31 stores a plurality of pieces of information representing a user's behavior schedule input by a scheduler or the like. The information representing individual action schedules is obtained by associating the identification ID with information representing the action name, information representing the action start date / time and action end date / time, and information representing the importance of the action. FIG. 3 is a diagram showing an example.

  The electronic file input receiving unit 32 receives data output from the camera if the electronic file is photo or video data, for example, and receives data from the document creation application if the electronic file is text data such as a memo. In addition, data may be received from an external recording medium such as a removable disk or a flash memory. Date and time information representing the creation time or input time is given to the electronic file.

  The first processing unit 1 includes a latitude / longitude database 11, a latitude / longitude / address database 12, a stay address calculation unit 13, a base address calculation unit 14, a manual input unit 15, and a stay location base association unit. 16.

  The latitude / longitude database 11 is used for accumulating latitude / longitude data calculated at regular intervals based on a GPS signal received by a GPS receiver (not shown) as data representing a user's stay history. It is done. FIG. 4 shows an example of stored latitude / longitude data.

  The latitude / longitude / address database 12 stores address conversion data in a range including at least a user's scheduled action area. This address conversion data stores the address information of the corresponding point in association with the latitude / longitude data of the position information. FIG. 5 shows an example of address conversion data stored in the latitude / longitude / address database 12. The address information is hierarchized into a plurality of address granularities according to the size of the area, for example, four levels of address granularity of “prefecture”, “city / town”, “place name”, and “address”. May be.

  The stay address calculation unit 13 reads a set of latitude / longitude data of the stay place included in the target period from the latitude / longitude database 11 and uses the read latitude / longitude data of the stay place as a key. By searching the address database 12, the address information corresponding to the latitude / longitude data of the place of stay is read out.

  The base address calculation unit 14 performs a process of determining the base address of the user based on the address information of each place of stay obtained by the stay address calculation unit 13. This process compares the total stay time of each stay address, selects a specified number of addresses from the stay addresses whose total stay time is longer than the threshold, and a pair of latitude / longitude data corresponding to the address, This is realized by determining this as a “base address”. In addition, when the user inputs a stay address arbitrarily input by the user in the manual input unit 15 and a set of latitude / longitude data, the base address calculation unit 14 sets the input data set as “a base. "Address" is determined.

  The manual input unit 15 is used by a user to manually input a set of a stay address representing the above “address as a base” and its latitude / longitude data from a keyboard or tablet-type input device.

The stay location base association unit 16 has the following processing functions.
(1) Based on the base address information determined by the base address calculation unit 14, the target period in which the latitude / longitude data is read exists in the period in which the user exists in the base address and the address other than the base. The process of classifying it as a period.
(2) Based on the information indicating the creation or input time given to the electronic file received from the electronic file input acceptance unit 32, the period during which the creation or input time of the electronic file existed at the base address A process to determine which period was included in an address other than the base.
(3) User behavior information executed during a period including the creation or input time of the electronic file is selectively read from the behavior information database 31 based on the time information. Then, if the read behavior information is one, processing to pass to the electronic file / behavior information storage unit 33 as tag information to which the behavior information is to be added.
(4) When there are a plurality of pieces of behavior information read from the behavior information database 31, the time difference between the execution time of these pieces of behavior information and the creation or input time of the electronic file is calculated. And the process which selects one action information with the smallest calculated time difference, and passes to the electronic file and action information storage part 33 as tag information which should give this selected action information.

The second processing unit 2 includes an action content analysis unit 21, an electronic file text analysis unit 22, and an action content base association unit 23.
The behavior content analysis unit 21 performs morphological analysis processing on the text data of the behavior information read from the behavior information database 31, and stores the types of words extracted by the analysis processing and the number of appearances in the behavior content base association unit 23. Process to pass.

  The electronic file text analysis unit 22 determines whether or not text data is included in the electronic file received by the electronic file input reception unit 32. If text data is included, the electronic file text analysis unit 22 performs morphological analysis processing on the text data. And a process of passing the type of words extracted by the analysis process and the number of appearances to the action content base association unit 23.

The action content base associating unit 23 includes information indicating the types of words and the number of appearances passed from the action content analyzing unit 21 and the electronic file text analyzing unit 22, and action information read from the action information database 31. Based on the information indicating the execution time and the information indicating the creation or input time of the electronic file received by the electronic file input receiving unit 32, the degree of conformity when the action information is attached to the electronic file as a tag is calculated. . The following conditions are used for calculation of the fitness.
(1) The degree of conformity is increased as the time difference between the creation or input time of the electronic file and the execution time of the behavior information is closer.
(2) Among the words included in the action content of the action information, the number of words included in the electronic file is a certain number or more, and the higher the number of words, the higher the fitness.
(3) The degree of matching is increased as words that do not appear in other behavior information and electronic file are included in both behavior information and electronic file.

  The electronic file / behavior information accumulating unit 33 receives the electronic file information received from the electronic file input receiving unit 32, the behavior information received from the stay location base association unit 16, and the behavior received from the behavior content base association unit 23. A process of storing the information in the tagged electronic file database 34 is performed.

  The electronic file management apparatus according to this embodiment includes a central processing unit (CPU). The stay address calculation unit 13, the base address calculation unit 14, the stay location base association unit 16, the action content analysis unit 21, the electronic file text analysis unit 22, the action content base association unit 23, and the electronic file / behavior information storage All the processing functions of the unit 33 are realized by causing the CPU to execute an application program stored in a program memory (not shown).

[Operation]
Next, behavior information tagging processing operations performed by the electronic file management apparatus configured as described above will be described. FIG. 2 is a flowchart showing the processing procedure and processing contents.
In the latitude / longitude database 11, for example, as shown in FIG. 4, latitude / longitude data representing the staying position of the user measured at a constant period and data including the measurement time represent the staying history of the user. The description will be made assuming that the behavior information that has already been accumulated as information and the behavior information input by the user by the scheduler, for example, is stored in the behavior information database 31 as shown in FIG.

(1) Accepting input of electronic file In a portable terminal as an electronic file management device, for storing electronic files such as photographs or moving images taken by a user with a camera, text documents created by writing notes, etc. in the terminal Suppose that an operation is performed.
Then, in the terminal, first, in processing step S1, the electronic file input receiving unit 32 receives the input electronic file and stores the input electronic file in a temporary storage area in the terminal. At this time, if the information indicating the creation date / time is not included in the electronic file, the electronic file input receiving unit 32 generates information indicating the input date / time and stores it in the electronic file.

  The electronic files are read into the first and second processing units 1 and 2 for the association process based on the stay location and the association process based on the action content, which will be described later. Here, when the electronic file is a text document, for example, the whole or part of the contents of the electronic file can be converted into text by recognizing characters in the photo by character recognition processing on the electronic file of the photo In the case of an electronic file, the first and second processing units 1 and 2 execute a stay location-based association process and an action content-based association process for the read electronic file. However, in the case of an electronic file that is difficult to convert into text, the action content-based association process by the second processing unit 2 is not performed, and only the stay location-based association process by the first processing unit 1 is performed. The

(2) Association processing based on stay location (2-1) Determination of stay location address serving as a base Upon receiving a notification that an electronic file has been input from the electronic file input receiving unit 32, the first processing unit 1 First, in processing step S <b> 2, the stay address calculation unit 13 reads latitude / longitude data for a predetermined period including the creation or input date / time of the electronic file from the latitude / longitude database 11. Subsequently, in processing step S3, the latitude / longitude data read from the latitude / longitude database 11 is converted into the address by using a conversion table of latitude / longitude data and address information stored in the latitude / longitude / address database 12. Convert to information. Then, the stay address information, the stay start time and the stay end time are passed to the base address calculation unit 14 and the stay location base association unit 16.

  Next, in processing step S4, the base address calculation unit 14 determines the base address of the user using the address information of each place of stay obtained by the stay address calculation unit 13 and the stay start time and stay end time. To do. This base address determination process compares the total stay time of each stay address and selects the specified number of addresses from the stay addresses with a long total stay time and the combination of latitude and longitude data corresponding to that address The combination of the selected address and latitude / longitude data representing the position is set as the “address as a base”.

The process for determining the base address of the user may be performed based on the combination of the stay address arbitrarily input by the user in the manual input unit 15 and the latitude / longitude data. In this case, the manual input unit 15 receives a stay address and a set of latitude / longitude data corresponding to the stay address as input. For example, input data representing “address: Shiba Park, Minato-ku, Tokyo, latitude: 35.658704, longitude: 139.745408” is received. Then, the base address of the user is determined by the above-described processing based on the received data on the stay location.
Information representing the base address of the user determined as described above is passed to the stay location base association unit 16.

(2-2) Creation of an electronic file or determination of a period to which an input date belongs When the base address is determined, the stay location base association unit 16 is first obtained by the stay address calculation unit 13 in processing step S5. It is determined and classified whether the stay period at each stay address corresponds to the above-determined “period at the base address” or “period other than the base address”.

  For example, if the stay period at each address such as “Company”, “Nearest station”, “Business trip destination” is as shown in FIG. 7 and the base address is determined as “Company”, The period of staying at "Company" is classified as "Period at base address", and the period of staying at "Nearest station" or "Business trip destination" is classified as "Period other than base address". The

  Subsequently, the stay location base associating unit 16 determines whether the electronic file is in the “period of being at the base address” or the “period of being outside the base address” based on the creation or input date and time of the read electronic file. In step S5, it is determined whether the data has been created or input in step S5. For example, in FIG. 8, it is determined that the electronic file a is created or input during “period other than the base address (1)”, and the electronic file b is generated or input during “period during the base address (2)”. It is determined that

(2-3) Selection of appropriate action information as a tag (when an electronic file is created or entered during the "period of staying at the base address")
As a result of the determination, if the electronic file was created or input during the “period at the base address”, the stay location base association unit 16 proceeds to processing step S6. Then, in this processing step S 6, all the behavior information representing the behavior executed during the above-determined “period at the base address” is read from the behavior information database 31. This action information reading process is performed by searching for the action start date and time and the action end date and time included in the action information.

Then, from the read action information, the most appropriate action information is selected when the electronic file is given as a tag. There are the following three types of processes for selecting the optimum behavior information.
(1) When there is no action information included in the corresponding “period of staying at the base address”, the action information to be provided is not provided, and the processing step S6 is ended as it is.
(2) If there is only one piece of behavior information included in the corresponding “period at the base address”, the behavior information is selected as behavior information to be added to the electronic file as a tag.
(3) If there are a plurality of behavior information included in the corresponding “period of staying at the base address”, one of the plurality of behavior information is selected.

As a selection method, for example,
(3-1) Among a plurality of read action information, the time difference between the execution date and time and the creation or input date of the electronic file is obtained, and one action information with the smallest time difference is selected.
(3-2) As shown in FIG. 3, information indicating the importance level is assigned to each action information stored in the action information database 31 in advance, and one action information item having the highest importance level is assigned. What to choose.
(3-3) Based on both the time difference and the importance information, one action information with the smallest time difference and the highest importance is selected.

(2-4) Selection of appropriate action information as a tag (when an electronic file is created or entered during the "period of being at an address other than the base")
As a result of the determination, if the electronic file was created or input during the “period of being at an address other than the base”, the stay location base association unit 16 proceeds to processing step S7. In this processing step S 7, all the behavior information representing the behavior executed during the above-determined “period of being at an address other than the base” is read from the behavior information database 31. This action information reading process is performed by searching for the action start date and time and the action end date and time included in the action information.

Then, from the read action information, the most appropriate action information is selected when the electronic file is given as a tag. As in the case described in (2-3) above, there are the following three types of processes for selecting the optimum behavior information.
(1) If there is no behavior information included in the corresponding “period other than the location”, the processing step S7 is terminated as it is, with no behavior information to be provided.
(2) When there is only one piece of behavior information included in the corresponding “period other than the base address”, the behavior information is selected as behavior information to be added to the electronic file as a tag.
(3) If there is a plurality of behavior information included in the corresponding “period of being at an address other than the base”, one of the plurality of behavior information is selected.

As a selection method, for example,
(3-1) Among a plurality of read action information, the time difference between the execution date and time and the creation or input date of the electronic file is obtained, and one action information with the smallest time difference is selected.
(3-2) As shown in FIG. 3, information indicating the importance level is assigned to each action information stored in the action information database 31 in advance, and one action information item having the highest importance level is assigned. What to choose.
(3-3) Based on both the time difference and the importance information, one action information with the smallest time difference and the highest importance is selected.

(2-5) Tagging of electronic file In the processing step S6 or processing step S7, when the most suitable behavior information is selected as a tag, the electronic file / behavior information accumulating unit 33 selects the tag in processing step S11. The electronic file to be attached is stored in the tagged electronic file database 34 after the action name of the selected action information is associated as a tag.

(3) Association processing based on action content (3-1) Analysis of action information contents (extraction of words from action information)
In the second processing unit 2, first, the action content analysis unit 21 performs morphological analysis processing on the text data of the action information read from the action information database 31 in process step S <b> 8. And the information showing the kind of word (for example, noun) extracted by this analysis process and the number of appearances is passed to the action content base associating unit 23. For example, as shown in FIG. 9, words such as “regular”, “meeting”, “Company A”, “meeting” are extracted from the action name of the action information. If the action name is untitled, a word is extracted from text data describing the action content.

(3-2) Analysis of electronic file text (extraction of words from electronic file)
In the second processing unit 2, subsequently, in processing step S <b> 9, the electronic file text analysis unit 22 determines whether text data is included in the electronic file received by the electronic file input receiving unit 32. If text data is included, morphological analysis processing is performed on the text data, and the type of words extracted by the analysis processing and the number of appearances are passed to the action content base association unit 23. For example, in the example shown in FIG. 9, words such as “Company A” and “Meeting” are extracted from the electronic file a.

(3-3) Selection of Action Information Appropriate as a Tag In the second processing unit 2, the action content base associating unit 23 then processes the action name of the action information and the text information included in the electronic file in process step S 10. The action information that should be given is determined as follows.
That is, the action content base associating unit 23 stores the types of words extracted by the electronic file text analysis unit 22 and the action content analysis unit 21 and the number of appearances thereof, and each action information read from the action information database 31. Based on the execution time and the creation or input time of the electronic file received by the electronic file input receiving unit 32, the fitness indicating “appropriateness of giving each behavior information tag to the electronic file” is expressed as follows: Calculate according to standards.

(1) The degree of conformity is increased as the time difference between the creation or input time of the electronic file and the execution time of the behavior information is closer.
(2) Among the words included in the action content of the action information, the number of words included in the electronic file is a certain number or more, and the higher the number of words, the higher the fitness.
(3) The degree of matching is increased as words that do not appear in other behavior information and electronic file are included in both behavior information and electronic file.

ただし、ｆiは行動内容i の適合度、ｗi は行動内容i に含まれる単語数、ｗi,d は行動内容i とタグ付けを行う電子ファイルとの両方に含まれ単語数、Ｎa は行動情報データベース３１に記憶された行動情報の数、Ｎd はタグ付き電子ファイルデータベース３４に記憶されている電子ファイル数、ｎi,j は単語j を含む行動情報データベース３１に蓄積されている行動情報の数、ｎd,j は単語j を含むタグ付き電子ファイルデータベース３４に蓄積されている電子ファイル数を示すものであり、またαは定数を示している。 Specifically, the fitness is calculated by the following equation.

Where fi is the fitness of action content i, wi is the number of words included in action content i, wi, d is the number of words included in both action content i and the electronic file to be tagged, and Na is the action information database. Nd is the number of behavior information stored in the tagged electronic file database 34, ni, j is the number of behavior information stored in the behavior information database 31 including the word j, nd , j indicates the number of electronic files stored in the tagged electronic file database 34 including the word j, and α indicates a constant.

Further, the action content base associating unit 23 compares the calculated fitness with a preset threshold β (β is a positive constant), and whether or not there is behavior information having a fitness exceeding the threshold β. Determine whether. As a result of this determination, if there is action information having a fitness level exceeding the threshold β, a maximum of N pieces of action information (N is a natural number) in order from the highest fitness level among these behavior information as tags. Select as action information to be given. Then, the information of the selected behavior information is passed to the electronic file / behavior information storage unit 33.
On the other hand, when there is no behavior information having a fitness level exceeding the threshold value β (β is a positive constant), it is determined that there is no behavior information to be provided as a tag, and the process of step S10 is terminated.

(3-4) Tagging to electronic file When action information suitable as a tag is selected in the processing step S10, the electronic file / behavior information accumulating unit 33 selects the electronic file to be tagged in the processing step S11. Is stored in the tagged electronic file database 34 after associating the action name of the selected action information as a tag.
If different action information is selected for the same electronic file in the first processing unit 1 and the second processing unit 2, all of these action information are associated as tags and then the tagged electronic file. Store in the database 34.

  As described in detail above, this embodiment includes the first processing unit 1 that performs the association process based on the stay location, and the second processing unit 2 that performs the association process based on the action content. When the first processing unit 1 accepts the input of the electronic file, the first processing unit 1 calculates the base address of the user based on the stay address included in the target period including the creation or input time of the input electronic file. The target period is classified into a period where the user exists at the base address and a period where the user exists outside the base address. Then, it is determined whether the creation or input time of the input electronic file is included in a period existing in the classified base address or a period existing in an address other than the base address, and in the determined period The executed action information is read from the action information database 31, and the optimum one is selected and stored in association with the electronic file as a tag.

  In the second processing unit 2, the electronic file text analysis unit 22 extracts words included in the input electronic file from the input electronic file, and the action content analysis unit 21 reads the action content of the read behavior information. Then, a word representing the action content is extracted, and the similarity between the electronic file and the action information is calculated based on the degree of matching of the extracted word. Then, action information with the calculated similarity being equal to or greater than a threshold is selected, and the selected action information is associated with the electronic file as a tag.

  Therefore, by the processing of the first processing unit 1, it is possible to narrow down the action information to be given to the electronic file by using the information on the staying place serving as the user's base and the staying period. In addition, by the processing of the second processing unit 2, action information whose similarity with the content of the electronic file is greater than or equal to a threshold value is selected from a plurality of action information, and this is attached to the electronic file as a tag. For this reason, even when an electronic file related to the behavior information is created or input at a time different from the execution time of the behavior information, the related behavior information can be appropriately given to the electronic file as a tag. It becomes. As a result, it is possible to accurately manage electronic files based on the user's own action history, and it is possible to efficiently search for a target electronic file even when the number of electronic files increases.

  In addition, when a plurality of the read action information exists when the tag is given, the time difference between the execution time of the plurality of action information and the creation or input time of the electronic file is calculated, respectively. The action information with the smallest calculated time difference is selected, and the selected action information is associated with the electronic file as a tag. Therefore, even when there are a plurality of action information executed during a period when the user exists at the base address or a period other than the base, the action information having the execution time closest to the creation or input time of the electronic file is selected. It becomes possible to attach to electronic files as tags.

  Furthermore, when the information indicating the importance is added to the behavior information, the behavior information having the highest importance is selected from the plurality of read behavior information based on the information indicating the importance. The selected action information is associated with the electronic file as a tag. Therefore, even when there is a plurality of action information executed during a period when the user exists at the base address or a period other than the base address, the action information having the highest importance is selected among these and the electronic information is used as a tag. Can be given to a file.

  The present invention is not limited to the above embodiment. For example, the number of appearances for each place of stay is calculated based on the place of stay data stored in the place of stay history database. The smaller the calculated number of appearances, the higher the importance. Set the degree information. Then, when tagging behavior information to the input electronic file, the degree of importance is higher than the stay location corresponding to the creation or input date of the electronic file within a predetermined period including the creation or input date of the electronic file. If there is a set staying place, the action information executed at the staying place may be selected and attached to the electronic file as a tag. 10 and 11 show an example of the processing.

  In the above embodiment, the case where all the functions shown in FIG. 1 are provided in the portable terminal possessed by the user has been described as an example. Of these functions, the latitude / longitude database 11 and the latitude / longitude / address database 12 are included.
