Description

  The present invention relates to a technique for presenting comparison result information that does not require designation of a physical element when comparing things and can be easily compared with a user.

  Non-Patent Document 1 proposes an interface that facilitates comparison by hiding other than the physical elements designated by the user when comparing things. However, the user has to specify the element, which is troublesome. For example, if a cheap and famous store is established near a store that is always used, the user will have to specify “price range” because the stores will be compared with each other by the physical element “price range”. For example, when a camera having a higher number of pixels than a camera owned by the market is released, the user will have to specify “number of pixels” because the cameras will be compared with each other by the physical element “number of pixels”.

  The components of the information presentation device may be distributed. For example, the display unit 16 may be provided on a terminal (smartphone or the like) used by the target user, and the other components may be provided on a server that can communicate with the terminal. Good.

FIG. 2 is a diagram illustrating an example of the matter DB 1.
The thing DB 1 includes a record for each of a plurality of things. The record includes an object name and an object ID of the corresponding object, and one or more categories to which the object belongs. The thing names are specific names of things such as “Restaurant A”, “Cafe B”, and “Model 2956 made by Company A”.

The information source of the matter DB 1 is arbitrary, and examples include a service provider, a book, a publicly available database, information on the web, and the like.
The thing DB1 is based on the existing technologies that make up the ontology (OWL Web Ontology Language http://www.asahi-net.or.jp/~ax2s-kmtn/internet/rec-owl-guide-20040210.html etc.) You may structure by providing a hierarchy. By providing a hierarchy, it is possible to specify a specific hierarchy in a comparison, for example, to compare between an izakaya and an Italian restaurant within the category of the same store, or to compare between different hierarchies. Therefore, a specific hierarchy to be compared may be added to the input.

FIG. 3 is a diagram illustrating an example of the physical element DB2.
The physical element DB 2 stores a record including a physical element name of a physical element related to the thing, physical element information including a physical element value that is an objective numerical value of the physical element, and an object ID of the thing. The The record includes, for example, physical element information for each of a plurality of different physical elements.

  For example, the physical element names of things belonging to the category “store” are “price range”, “number of seats”, “number of family members”, and the like. For example, the physical element names of things belonging to the category “camera” are “weight”, “number of pixels”, “thickness”, and the like. A physical element can be rephrased as an attribute.

  For example, if the average payment amount at the restaurant A is 2000 yen, the physical element information including the physical element name “price range” and the physical element value “2000” is stored in the record corresponding to the restaurant. For example, the unit of the physical element value “2000” is “yen”, but this may be associated with the physical element name “price range”.

  For example, assuming that the weight of the camera A model 2956 made by company A is 230 g, the physical element information including the physical element name “weight” and the physical element value “230” is stored in the record corresponding to the camera. For example, the unit of the physical element value “230” is “g”, but this may be associated with the physical element name “weight”. The granularity of the physical element value may be determined in advance, or the granularity may be arbitrary.

  The information source of the physical element DB 2 is arbitrary, and examples include a service provider, a book, a publicly available database, information on the web, and the like.

FIG. 4 is a diagram illustrating an example of the impression word group DB 3.
A plurality of impression words are stored in the impression word group DB3. The information source of the impression word group DB3 is arbitrary, and examples include a service provider, a book, a publicly available database, information on the web, and the like.

FIG. 5 is a diagram illustrating an example of the physical element impression word association DB 4.
The physical element impression word association DB 4 stores association information including a physical element name and an impression word used by the target user for the physical element of the physical element name.

FIG. 6 is a diagram illustrating an example of the impression DB 5.
In the impression DB 5, for a set of a physical element name and a physical element name for the physical element of the thing of the thing ID and the impression word for the physical element, the target user indicates that the impression word is important for the relevant thing. The impression word importance indicating the degree of feeling is inputted from the outside, and the impression word importance and the impression word importance information including the impression word are generated, so the record including the impression word importance information and the matter ID Is accumulated. The record includes, for example, impression word importance information for each of a plurality of different impression words.

FIG. 7 is a diagram illustrating an example of the structured DB 6.
The structured DB 6 indicates an element value obtained by normalizing a physical element value of the thing with respect to a physical element related to the thing, and a degree to which the target user feels that an impression word used by the target user is important for the physical element. Since the weight value obtained by normalizing the impression word importance is calculated and the physical element value weight information including the element value and the weight value is generated, the record including the physical element value weight information and the object ID of the object Is accumulated. The record includes, for example, physical element value weight information for each of a plurality of different physical elements.

  Returning to FIG. 1, the processing performed in this embodiment will be described in the order of pre-processing and information presentation processing.

(Pre-processing)
The physical element extraction processing unit 11 generates a record in the physical element DB 2 for each of all the matter IDs in the matter DB 1 and stores the corresponding matter ID and physical element information in the record.

  Since the impression correspondence processing unit 12 selects an impression word from the impression word group DB 3 for each physical element name in the physical element DB 2 by an external operation or the like, the impression correspondence processing unit 12 Correspondence information including the element name and the impression word is generated and stored in the physical element impression word correspondence DB 4. When two or more impression words are selected, the impression association processing unit 12 generates and stores association information for each impression word.

  Which impression word is selected, for example, what impression word is used in the target user's blog, word-of-mouth, product review, user survey, interview results, etc. (hereinafter referred to as the target user's blog, etc.) Is determined based on whether For example, if the target user feels “high” in the price range of restaurant A and leaves such a sentence on a blog or the like, the impression word “high” is selected. For example, if the target user feels that the weight of the camera of model A made by company A is “heavy” and leaves such a sentence in the product review, the impression word “heavy” is selected.

The impression extraction processing unit 13 gives an impression indicating the degree to which the target user feels that the impression word is important for the corresponding thing for the combination of the thing ID in the thing DB 1 and the impression word in the physical element impression word correspondence DB 4. Since the word importance is given by an external operation or the like, the impression word importance information including the impression word importance and the impression word is generated, and the corresponding impression word importance information and the object ID are generated for each event ID. Is generated in the impression DB 5.
The impression word importance is set so high that the user strongly feels that the impression word is important for the thing.

  How much impression word importance is set, such as if there is a sentence on the target user's blog etc. that indicates how important the impression word is to the target object Determined based on For example, if the usage frequency of “high” used for the price range of restaurant A is high, the impression word importance level is also set high. For example, when the usage frequency of “heavy” used for the camera weight of the model 2956 manufactured by Company A is low, the impression word importance is also set low. For the analysis of impression words, for example, a method using a tool such as Nazuki (Japanese analysis engine Nazuki, NTT Data, http://www.nttdata-nazuki.jp/index.html) can be considered.

  The structured processing unit 14 generates a record in the structured DB 6 for each of all the matter IDs in the impression DB 5, and stores the corresponding matter ID and physical element value weight information in the record.

  Here, the structuring processing unit 14 sets all the physical element values related to the physical element of the physical element name of the set for the set of the object ID, the corresponding physical element name, and the corresponding physical element value in the physical element DB2, and An element value obtained by normalizing a pair of physical element values is calculated.

Specifically, the structuring processing unit 14 calculates the element value using the formula (1).

Note that u _{i, max} , u _{i, min} may be the maximum value and the minimum value in the possible range of the physical element value corresponding to the physical element i, respectively.

  In addition, the structuring processing unit 14 calculates a weight value obtained by normalizing all the importance levels of impression words related to the set for each set of the thing ID and the corresponding physical element name in the impression DB 5.

Specifically, the structuring processing unit 14 calculates the weight value using the equation (2).

The weight value is also a value indicating how much the corresponding physical element affects the impression of the target user regarding the corresponding thing.
When the above pre-processing is completed, the information presentation processing can be performed.

(Information presentation process)
FIG. 8 is a diagram illustrating an example of the input interface.
The information presentation processing unit 15 displays an input interface as shown in the figure. For example, the target user separately inputs a category of camera. And if pull-down menu M1 is operated, the information presentation process part 15 will display the several thing name applicable to the said category in thing DB1. The target user selects a desired one by operation.

  For example, the target user selects an object name (for example, a model 2956 manufactured by Company A) indicating a camera owned by the target user.

  When the pull-down menu M2 is operated, the information presentation processing unit 15 displays three comparison methods of “exemplary”, “difference comparison”, and “similarity comparison”. The target user selects a desired one by operation.

  In addition, when the pull-down menu M3 is operated, the information presentation processing unit 15 deletes a record including the same category as the above-described input category (excluding a record including the name of the thing selected from the pull-down menu M1) from the thing DB1. Search, read the name of the thing from the record, and display multiple such names. The target user selects a desired one by operation.

  For example, the target user selects an object name (for example, a model P-10 manufactured by B company) indicating a camera to be purchased.

Note that the selection of an object name by operating the pull-down menu M3 may be omitted.
For example, when it is desired to convert the information at hand (for example, when the function of this embodiment is input on the browser as a tool for converting the contents described in the web content, or when input is performed on the terminal as a dictionary tool) There is a possibility that the selection of the thing name from the pull-down menu M3 may be omitted.

  When the above operation is completed, the user operates the presentation button B1.

FIG. 9 is a diagram showing a flow of processing in the information presentation processing unit 15.
When the presentation button B1 is operated, the information presentation processing unit 15 reads a record including an object ID corresponding to the object name selected from the pull-down menu M1 from the structured DB 6 (S1).

  Next, the information presentation processing unit 15 determines whether or not an object name to be compared is selected from the pull-down menu M3 (S3).

  If the object name to be compared is not selected from the pull-down menu M3 (S3: NO), the information presentation processing unit 15 compares the object based on the comparison method selected from the pull-down menu M2, the object DB 1, and the structured DB 6. Is determined (S5).

  Here, the information presentation processing unit 15 searches the event DB 1 for a record including the same category as the input category (excluding a record including the event name selected by the pull-down menu M1), and from the record The matter ID is read (S7). For example, a plurality of event IDs matching such conditions are read out. And the information presentation process part 15 searches the record (it is called a comparison object record) containing each thing ID from structured DB6.

  FIG. 10 is a diagram illustrating an example of the process (S5) for each comparison method.

  If the comparison method is “exemplary”, for example, the information presentation processing unit 15 calculates the similarity between the record read in step S1 and the comparison target record, and compares the object name corresponding to the maximum similarity with the comparison target Choose as. For calculating the similarity, a calculation formula for the similarity described in the following reference can be used.

  Rika Mochizuki, Tomoki Watanabe, Toru Kobayashi, “Emotion Communication Model based on Life-Log Comparison-Mutual understanding through comparable experiences-”, IEEE / IPSJ, SAINT2012, pp.91-99, 2012.

  If the comparison method is “difference comparison”, for example, the information presentation processing unit 15 selects the maximum weight value from the record read in step S1, and reads the element value from the physical element value weight information including the weight value. , Select the element value that has the smallest difference from the read element value from the element values of the comparison target record for the physical element name corresponding to the element value, and compare the thing in the comparison target record that includes the element value Choose as. That is, the comparison target is narrowed down to one.

  If the comparison method is “similar comparison”, the information presentation processing unit 15 reads, for example, an arbitrary weight value of the record read in step S1, and the weight of the comparison target record for the physical element name corresponding to the weight value From the values, the weight value that minimizes the difference from the read weight value is selected, and the thing of the comparison target record including the weight value is selected as the comparison target. That is, the comparison target is narrowed down to one.

  Returning to FIG. 9, the information presentation processing unit 15 selects the comparison object name from the pull-down menu M3 (S3: YES), or selects the comparison object in step S5 (restricts the object). If so, a record including the name of the object selected from the pull-down menu M1 and a record including the name of the object to be compared are read out from the physical element DB2, and the physical element for each physical element name common to each record is read. Comparison result information is generated so that the physical element value of one record and the physical element value of the other record are written side by side in association with the name, and displayed on the display unit 16 (S7), and the process ends.

FIG. 11 is a diagram illustrating a display example of comparison result information.
The figure shows a display example when the comparison method is “similar comparison”. For example, the name of an object selected from the pull-down menu M1 and the name of an object to be compared (the name of an object selected from the pull-down menu M3 or a narrowed down name) Are displayed side by side at the top of the screen. Below that, the physical element value “15 million” and its unit “pixel”, the physical element value “12 million” and its unit “pixel” are displayed side by side in association with the physical element name “number of pixels”. . Below that, the physical element value “260” and its unit “sheet”, the physical element value “240” and its unit “sheet” are displayed side by side in association with the physical element name “photographable number”. Below that, the physical element value “20” and its unit “times”, and the physical element value “5” and its unit “times” are displayed side by side in association with the physical element name “optical zoom”.

  That is, in the “similarity comparison”, “number of pixels” is similar between “15 million” and “12 million”, and “photographable number” is similar between “260” and “240”. These are displayed with priority.

  On the other hand, although not shown, the comparison method is “difference comparison”, the “pixel count” is “15 million” and “100,000”, and the difference is large, and the “photographable number” is also “260” and “10”. If the difference is large, these are displayed with priority.

  As described above, according to the present embodiment, when the target user compares things, the impression word and the impression word importance are defined, so that it is automatically important even if the target user does not specify it. Comparison result information giving priority to physical elements can be presented. Thereby, even on the screen of the display unit 16 having a small amount of information that can be displayed, and even when there is no physical element that the target user wants to specify, comparison result information giving priority to the physical element that is expected to be highly demanded by the target user Can be presented. In other words, the similarity / difference between things can be presented in an easy-to-understand manner.

  In addition, a computer program for causing a computer to function as the information presentation device of the present embodiment can be recorded on a computer-readable recording medium such as a semiconductor memory, a magnetic disk, an optical disk, a magneto-optical disk, a magnetic tape, and the Internet. It can be widely distributed by being transmitted through a communication network such as
