Description

  The present invention relates to an information presentation apparatus, an information presentation method, and a program for acquiring and presenting desired information from a vast amount of information such as the web, and in particular, an information presentation apparatus for acquiring and presenting experience information, The present invention relates to an information presentation method and program.

  Various information exists on the web, and the user can refer to experience information of others on the web when considering an action schedule such as a holiday or a long vacation. However, since the amount of information on the web is enormous, it is not easy to efficiently obtain the experience information required by the user from the web.

  Search engines are provided on the web. The search engine extracts a web page including a keyword specified by the user and provides the link information to the user. The user can find a web page related to the keyword by specifying a keyword related to the experience information and performing a search with a search engine.

  However, when considering an action schedule such as a holiday or a long vacation, when a user searches for a web page using a conventional search engine by specifying a keyword of interest, the extracted web page includes, for example, the keyword. Web pages that are not related to experience information are also included, such as pages that provide knowledge about. Therefore, simply specifying a keyword for a matter of interest and performing a search using a conventional search engine cannot efficiently acquire other person's experience information related to the keyword.

  In this case, when a conventional search engine searches for a keyword “experience” together with the keyword, a web page including the keyword and the term “experience” is extracted. For example, when considering an action plan related to "ice", a search using a conventional search engine using the keywords "ice" and "experience" will result in a web containing the terms "ice" and "experience". A page is extracted. However, when the term “experience” is not used in a web page including contents such as “I ate shaved ice” and “I saw drift ice”, such a web page is not extracted.

  Considering this point, for example, if you search using keywords such as “eat” and “view” together with the keyword “ice”, you will find experience information such as “I ate shaved ice” and “I saw drift ice” It is possible to search for web pages containing.

  In Patent Document 1, when a document is given, even if there is no input of a keyword or the like, what the writer of the document describes about what experience, that is, the subject of the writer's experience of the document An experience information extraction device that presents an experience is disclosed. This experience information extraction device uses the relationship between a phrase (experience expression) that expresses the use or experience / experience of a thing and the phrase that is the subject of the experience, the relationship between the experience expression and the category to which the subject of the experience belongs, or Then, referring to an experience expression dictionary that defines either the relationship between the experience expression, the object of the experience, and the category, the phrase or category corresponding to the corresponding experience expression is selected in the input document.

JP 2007-280052 A

  However, as described above, in a method in which the user searches for experience information using a conventional search engine by devising keywords according to the search target, a large amount of experience information is extracted in a random manner. It becomes difficult for the user to determine which experience information out of the large amount of chaotic experience information should be referred to in examining his / her action schedule.

  With the technique of Patent Document 1, information on a combination of an experience expression and an experience target or an experience target category is obtained. However, Patent Document 1 is a technique for extracting a description of an experience from a given document when given a document. A technique for acquiring experience information from a vast amount of information, The method of how to connect with the determination of a user's action schedule is not shown.

  In addition, when experience information is searched using a conventional search engine using a keyword, experience information that does not include the specified keyword is not searched at all. For this reason, the user needs to select keywords from multiple sides in order to obtain desired experience information. However, even if a search is performed using many types of keywords, the experience information is not searched for the types of actions that the user cannot conceive.

  For example, if you search for the target keyword “ice” by combining the action keywords “eat” and “view”, you can get experience information on “ice” other than “eat” and “view”. I can't. A user who does not know that there is an ice hotel when there is experience information “I stayed at an ice hotel” on the web does not use the keyword “stay”. As a result, the user cannot obtain the experience information of another person who has stayed at an ice hotel and cannot find new discoveries that exceed the user's own ideas when examining the action schedule.

  In the technique of Patent Document 1, for each experience target or each experience target category, a general behavioral expression for the target or category is fixed in advance. Therefore, if there is an action expression other than these fixed action expressions for each object or each category in the document, it is not determined as experience information. Therefore, in this case as well, only general experience information can be obtained, and even when such experience information is referred to, when a user considers an action plan, a new discovery beyond the general idea can be made. I can't get it.

The RAM 103 is used as a temporary storage memory when the CPU 102 performs processing. The ROM 104 stores a program executed by the CPU 102. The hard disk 105 stores information data such as a user attribute and a dictionary used for morphological analysis which will be described later. Further, the hard disk 105 may store a document information search result, a morphological analysis result, and the like, which will be described later.

  FIG. 1 is a block diagram showing the configuration of the information presentation apparatus according to the first embodiment of this invention. The information presentation apparatus having the hardware configuration shown in FIG. 3 executes the program according to the embodiment of the present invention, thereby realizing the configuration shown in FIG.

  As shown in FIG. 1, the information presentation device 10 includes a network connection unit 11, an information acquisition unit 12, a morpheme analysis unit 13, a search condition determination unit 14, a user attribute storage unit 15, and an experience information classification unit 16. And an experience cost determination unit 17 and a presentation unit 18.

  The network connection unit 11 transmits and receives data via the Internet. The network connection unit 11 receives the data and provides it to the information acquisition unit 12, the search condition determination unit 14, and the user attribute storage unit 15. The network connection unit 11 receives data from the information acquisition unit 12 and the presentation unit 18 and transmits it.

  The information acquisition unit 12 uses the search condition for search execution determined by the search condition determination unit 14 to acquire document information that matches the search condition from the web. In the present embodiment, the information acquisition unit 12 searches the blog database 50 using a search condition, and acquires a blog article as document information. The information acquisition unit 12 may search a plurality of blog databases. Further, the information acquisition unit 12 may not only search the blog database to acquire blog articles but also acquire document information widely from websites on the Internet.

  The morpheme analysis unit 13 performs morpheme analysis on the document information included in the blog article. The morpheme analysis unit 13 performs morpheme analysis and particularly extracts verbs.

  The search condition determination unit 14 determines a search condition used for the search in the information acquisition unit 12 based on the search condition received by the network connection unit 11. Specifically, when the network connection unit 11 receives a keyword (interest keyword) input by the user on the user terminal 40, the keyword search unit searches for a keyword group including terms related to the interest keyword based on the received interest keyword. It is determined as a search condition for execution. Here, the related terms are, for example, a thesaurus of interesting keywords (narrowly defined terms, broad terms, synonyms, related terms, etc.). Also, statistically analyze the input status of keywords of many users, store other keywords that are often input together with a predetermined keyword, and use the keywords used in the set as related terms Also good.

  Note that the search condition determination unit 14 may determine only the interest keyword input by the user at the user terminal 40 as the search condition for the search performed by the information acquisition unit 12. The search condition determination unit 14 may include a condition of information update date and time in addition to the keyword as a search condition for the search performed by the information acquisition unit 12. The search condition determination unit 14 may determine, as a search condition, a condition related to a search range, whether to search the entire web or only the blog database, in addition to the keyword. When the information acquisition unit 12 searches the blog database, the search condition determination unit 14 may also determine a search range condition as to which blog database to search from among a plurality of blog databases.

  The user attribute storage unit 15 stores the user attribute received by the network connection unit 11. The user attributes are input by the user at the user terminal 40 and transmitted from the user terminal 40. The user attributes stored in the user attribute storage unit 15 include information such as the user's age, sex, and address.

  The experience information classification unit 16 analyzes a phrase including a word indicating behavior and a keyword of a keyword group determined by the search condition determination unit 14 included in the document information acquired by the information acquisition unit 12. The phrase including the keyword of the keyword group determined by the search condition determination unit 14 becomes a phrase indicating the action target with respect to the word indicating the action.

  FIG. 4 is a diagram showing the analysis result of the document information in the embodiment of the present invention. For each blog article acquired by the information acquisition unit 12, the experience information classification unit 16 converts a phrase including a keyword into a phrase indicating an action target (a phrase indicating “what”, hereinafter referred to as “action target phrase”). The number of appearances is counted to create a term document matrix as shown in FIG.

  In the example of FIG. 4, an interest keyword “ice” is input by the user, and the search condition determination unit 14 gives the keyword group “ice”, “ice”, and “snow” to the information acquisition unit 12 in response to this. The case where a search is performed is shown. Based on the document information, the experience information classification unit 16 uses words (“shaved ice”, “ice skating” including the keywords “ice”, “ice” (synonymous with “ice”), and “snow” (related words of “ice”). ”,“ Snow Festival ”,“ Ice Concert ”, etc.) and the number of appearances is counted.

  In addition, the information classification unit 16 uses the verb extracted by the morphological analysis unit 13 for each blog article acquired by the information acquisition unit 12 as a word indicating behavior (a word indicating “how to”, hereinafter “action word”). ")" And count the number of applications.

  In the present embodiment, for each blog article, the experience information classifying unit 16 determines a group to which each blog article belongs based on the combination of the action target word / phrase with the highest appearance frequency and the action word with the highest appearance frequency. Perform clustering. In the example of FIG. 4, in article 1, “shaved ice” appears five times as the action target phrase, and no other phrase that matches the keyword group is extracted. In Article 1, “Make” appears three times, “Eat” appears twice as an action word, and no other verbs appear. Therefore, the article 1 is classified into a group “make shaved ice” based on “shaved ice” having the highest number of appearances as the action target phrase and “making” having the highest number of appearances as the action words.

  Article 2, article 3, article 4, article 5, article 6,... Are similarly classified into groups. Article 2 is categorized as a group “buying an ice tray”, Article 3 is categorized as a group “going to ice skating”, Article 4 is categorized as a group “watching an ice festival”, and article 5 Is classified into the same group as “Make Shaved Ice”, which is the same as Article 1, and Article 6 is classified into the group “See the drift ice”.

  The group is not prepared in advance, and is generated based on the combination of the action target word and the action word included in the document information when the document information is clustered.

  In order to improve the accuracy of clustering, the experience information classification unit 16 may count only the verbs described in positions close to the action target word / phrase as action words and count the number of appearances. Specifically, only verbs that have a number of characters between the action target phrases within a predetermined number or less may be counted as action words. Further, only verbs included in the same sentence as the action target phrase may be counted as action words.

  In the above example, the experience information classification unit 16 classifies one article into one group based only on the action target words and action words having the highest number of appearances. However, the experience information classification unit 16 may classify one article into a plurality of groups based on all the action target words and action words that have appeared. In this case, for example, “Make” and “Eat” appear as the action words in the article 1, so the experience information classification unit 16 categorizes the article 1 as “shaved ice” and “shaved ice”. Into the group of “eating”. In addition, since the action target words “snow festival” and “drift ice” and the action word “see” appear in the article 4, the experience information classification unit 16 calls the article 4 “see the snow festival”. It is classified into a group and a group of “Looking at drift ice”

  Returning to FIG. 1, the experience cost determination unit 17 analyzes the words included in the document information belonging to the group generated by the experience information classification unit 16 and determines the height of the experience cost of the group.

  Here, the experience cost is a cost for realizing the experience and is an index indicating the difficulty in realizing the experience. The experience cost includes a distance cost, a time cost, a monetary cost, a difficulty level, a rarity level, a user attribute matching level, a fashion level, and the like.

  The distance cost is a cost index indicating the geographical distance from the user's address to the place where each group experience is performed. The distance cost is determined based on the geographical distance from the user's address to the place where each group's experience is performed, and the distance cost increases as the distance increases.

  FIG. 5 is a diagram for explaining a method for determining the distance cost. The experience cost determination unit 17 obtains the distance between the reference location and the place name included in the blog article using the user's address location as the reference location. The experience cost determination unit 17 obtains the distance between the reference place and the place name included in the blog article for each of the plurality of blog articles included in the group. And the experience cost determination part 17 determines the nearest distance as the distance cost of the group among the distance of the several blog article contained in one group.

  The experience cost determination unit 17 reads the user's address from the user attribute storage unit 15 and uses it as a reference location. The place names included in the blog article are extracted by the morphological analysis unit 13. The distance between the reference place and the extracted place name can be obtained using the route search function of the map software.

  In the example of FIG. 5, articles 1 to 3 are included in the group “eating shaved ice”. Article 1 contains the place name “Kariya City, Aichi Prefecture”, Article 2 contains the place name “Meguro 2-chome”, and Article 3 contains the place name “Yokohama City”. It is. The distances between the place names of the articles 1 to 3 and the reference place are “329 (km)”, “3.9 (km)”, and “33.7 (km)”, respectively. In this case, the experience cost determination unit 17 determines the smallest “3.9” as the distance cost of the group “eat shaved ice”.

  In the above example, the shortest distance among the distances between the place name and the reference place included in each of the plurality of blog articles in the group is the distance cost. However, the method for determining the distance cost is not limited to this. I can't. The experience cost determination unit 17 may set the average value of the distance between the place name and the reference place included in each of the plurality of blog articles in the group as the distance cost of the group. The experience cost determination unit 17 may set the distance between the place name and the reference place included in the representative blog article among the plurality of blog articles in the group as the distance cost of the group. In this case, the experience cost determination unit 17 may select, for example, a blog article including the most action target words and phrases, a blog article with the latest creation date, and the like as a representative blog article.

  The time cost is a cost index indicating the length of time required to realize the experience. The time cost is determined based on the distance between the user's address and the place name included in the blog post and the time taken to complete the experience. The longer the distance, the higher the time cost, and the longer it takes to complete, the higher the time cost.

  For each action word candidate, the experience cost determination unit 17 has a table in which the time taken to complete the action indicated by the action word is defined. The experience cost determination unit 17 refers to this table and obtains the time required to complete the action indicated by the action word included in each group. In this table, for example, an action word “eat” is defined as “1 hour”, and an action word “see” is defined as “2.5 hours”. ing.

  The monetary cost is a cost index indicating the amount of money required to realize the experience. The monetary cost is determined based on the distance between the user's address and the place name included in the blog post and the amount of money required to perform the experience. The longer the distance, the higher the transportation costs, and the higher the monetary cost. Also, the greater the amount required for realization, the higher the monetary cost.

  The experience cost determination unit 17 has a table in which the amount of money necessary for realizing the action indicated by the action word is defined for each action word candidate. The experience cost determination unit 17 refers to this table to obtain an amount necessary for realizing the action indicated by the action word included in each group. In this table, for example, the action “go” is “0 yen” (transportation is considered separately, so the money required to realize only “go” is 0), and “stay” The amount of money required to realize the action indicated by each action word is defined, such as “15,000 yen” for the action. Note that the experience cost determination unit 17 may extract a word related to the amount of money from the document information and determine the amount of money necessary for realizing the action of the document information.

  The difficulty level is a cost index indicating the level of labor and skill required for the experience. The difficulty level is determined based on the behavior attribute difficulty level of the behavior word and the number of appearances of the behavior word in each group. The higher the behavior attribute difficulty level is, the higher the difficulty level is, and the more the behavior word appears in the group, the lower the difficulty level.

  The experience cost determination unit 17 has a table in which a behavior attribute difficulty level is defined for each behavior word candidate. The experience cost determination unit 17 refers to this table to obtain the behavior attribute difficulty level of the behavior indicated by the behavior word included in each group. In this table, for example, “100” is the action “becoming”, “30” is the action “see”, “10” is the action “buy”, and the action attribute difficulty level of the action indicated by each action word Is defined.

  FIG. 6 is a diagram for explaining a difficulty level determination method according to the embodiment of the present invention. In the example of FIG. 6, for the group “see drift ice”, the behavior attribute difficulty of the action word “see” is “30”, and the number of appearances of the action word “see” in the group is “6”. is there. The experience cost determination unit 17 divides the behavior attribute difficulty “30” by the number of appearances “6” and determines the difficulty level as “5.0”. Similarly, for the group of “buying an ice tray”, the experience cost determination unit 17 similarly divides the behavior attribute difficulty “10” of “buy” by the number of occurrences of “buy” in the group “4”. The difficulty level is determined as “2.5”.

  Rareness is a cost index that indicates a small number of opportunities to realize an experience. The rarity is determined based on the number of blog articles included in each group. The scarcity increases as the number of blog articles in the group decreases.

  The user attribute matching degree is a cost index indicating the degree of matching between the user attribute and the blog article author attribute. The user attribute matching degree is determined based on the number of matches between each attribute of the user and the corresponding attribute of the author of the blog article. The greater the number of matching attributes, the higher the user attribute matching degree.

  The experience cost determination unit 17 analyzes the blog article and determines the age and sex of the author of the blog article. Then, the experience cost determination unit 17 reads the user attribute from the user attribute storage unit 15 and analyzes the age and sex of the author of the blog article obtained by analysis, and the user age and gender read from the user attribute storage unit 15. Compare gender. The experience cost determination unit 17 determines the user attribute matching degree based on the comparison result.

  The degree of fashion is a cost index indicating how popular the experience is now. The popularity is determined based on the number of blog articles included in the group and the creation date and time of each blog article. The greater the number of blog articles, the higher the trend, and the newer the blog article creation date, the higher the trend.
