At this time, if the work information search unit 114w determines that there is no work name information with a work name that matches the word (step S17; No), the work information search unit 114w includes a work name including a part of the extracted words ( The work name information of the partially matching work name is searched from the work table TW of the work DB 150w (step S18). In addition, the work information search part 114w may search the work name information showing the work name including a part of the independent word extracted at step S15.

  Next, the work information search unit 114w determines whether or not there is work name information having a work name that partially matches the product name represented by the stored product name information (that is, whether or not search has been performed) (step S19). ).

  In step S16, when the work information search unit 114w determines that there is work name information with a completely matching work name (step S14; Yes), when it is determined that there is work name information with a work name that matches the word (step S14) S17; Yes), or when it is determined in step S17 that there is work name information with a partially matching work name (step S19; Yes), the merchandising determination unit 115 uses the product name information acquired in step S11. A product with a product name represented (hereinafter referred to as a product to be processed in this flow) is represented by the product name information retrieved in step S13, step S16, or step S18 (hereinafter, in this flow, A merchandising discrimination process as shown in FIG. 7 is executed to discriminate whether or not the target work has been commercialized (step S). 0).

  When the execution of the merchandising determination process of FIG. 7 is started, the merchandising determination unit 115 displays the product name represented by the product name information acquired in step S11 or a keyword generated from the product name as shown in FIG. The search keyword to be transmitted to the search engine 301 is set (step S31). The keyword generated from the product name includes, for example, a word extracted from the product name by morphological analysis. The keyword set in step S31 is hereinafter referred to as a product name keyword.

  Next, the merchandising determination unit 115 sends a search request (that is, a search request) to search based on the search keyword set in step 31 and the search condition of the Web content based on the search keyword to the search engine 301. The information transmission unit included in the information processing apparatus 100 is controlled to transmit to (step S32). Thereafter, the merchandising determination unit 115 controls the information receiving unit to receive information representing the search result (hereinafter referred to as a product search result) based on the search keyword transmitted in step S32 from the search engine 301. Information representing the product search result is acquired from the information receiving unit (step S33). Next, the merchandising determination unit 115 acquires N URLs indicating the locations of web contents such as searched home pages from the product search results represented by the acquired information in descending order of display order in the search results ( Step S34).

  Next, the merchandising determination unit 115 sets a work name represented by the work name information searched in step S13, step S16, or step S18 or a keyword generated from the work name as a search keyword (step S35). . The keyword generated from the work name includes, for example, a word extracted from the work name by morphological analysis. The keyword set in step S35 is hereinafter referred to as a work name keyword.

  Next, the merchandising determination unit 115 executes the same processing as steps S32 and S33 (steps S36 and S37). Thereafter, the merchandising determination unit 115 acquires M URLs representing the locations of the searched contents in descending order of display order in the search results from the search results represented by the acquired information (hereinafter referred to as work search results). (Step S38).

  Thereafter, the merchandising determination unit 115, based on the N URLs acquired in step S34 (hereinafter referred to as product URLs) and the M URLs acquired in step S38 (hereinafter referred to as work URLs), The search result similarity between the product search result acquired in step S33 and the work search result acquired in step S37 is calculated (step S39).

  The search result similarity is an index indicating the degree of similarity between the product search result and the work search result. The closer the search result similarity is to the value “1”, the more similar the product search result and work search result are. Represents that As a specific example, the merchandising determination unit 115 calculates the search result matching degree using the following equation (1).

Search result similarity = URL match / N (1)
However, the URL matching degree is an index representing the degree of matching between the product search result and the work search result by the number of URLs that match any of the M work URLs among the N product URLs.

  The merchandising determination unit 115 uses the following formulas (2) and (3) to display the product URL when the product URL having a higher display order in the product search result matches the work URL. The search result matching degree weighted by the display order may be calculated so that the product URL of the display order lower than the order has a higher value than when the product URL matches the work URL.

但し、Ｆ_ｉは、商品検索結果における表示順位ｉの商品ＵＲＬが作品検索結果における作品ＵＲＬと一致する場合に値１となり、一致しない場合に値０となる関数である。

However, F _i is a function having a value of 1 when the product URL of the display order i in the product search result matches the product URL in the product search result, and a value of 0 when not matching.

  After step S39, the commercialization determination unit 115 determines whether or not the calculated search result similarity is equal to or greater than a predetermined threshold A (step S40). At this time, if the merchandising determination unit 115 determines that the search result similarity is equal to or greater than the predetermined threshold A (step S40; Yes), the processing target product is a product obtained by commercializing the processing target work. It discriminate | determines (step S41). Thereafter, the commercialization determination unit 115 ends the execution of the commercialization determination process. The threshold A is stored in the information storage unit 150.

  In step S40, if the merchandise discrimination unit 115 determines that the search result similarity is smaller than the predetermined threshold A (step S40; No), the merchandise to be processed is determined not to be a product obtained by commercializing the work to be processed. (Step S42). Thereafter, the commercialization determination unit 115 ends the execution of the commercialization determination process.

  The merchandising determination unit 115 acquires one URL (that is, N = 1) representing the location of the searched content from the product search result in descending order of display order in the search result (step S34). A configuration can be adopted in which one URL representing the location of the searched content (that is, M = 1) is acquired from the search results in descending order of display order in the search results (step S38). In this configuration, the merchandising determination unit 115 determines whether or not the URL acquired from the product search result matches the URL acquired from the work search result. The target product may be determined to be a commercialized work to be processed.

  In step S19 in FIG. 5, when the work information search unit 114w determines that there is no work name information with a partially matching work name (that is, no search is performed) (step S19; No), or after step S20, When the merchandise discrimination unit 115 determines that the target product is not a product that is a target product to be processed (step S21; No), the display control unit 116 provides the product (that is, recorded on the product DVD). The terminal device 201 is controlled to display on the display unit of the terminal device 201 that the work information of the work cannot be acquired from the information storage unit 150 (step S22). As a specific example, the display control unit 116 transmits to the terminal device 201 information representing a message indicating that the message cannot be acquired and information for instructing to display a message according to the information.

  Thereafter, the display control unit 116 controls the terminal device 201 to display a message prompting the user to input the work ID of the work provided by the processing target product (step S23). Next, the work information acquisition unit 111w acquires the work ID transmitted from the terminal device 201 from the information reception unit included in the information processing apparatus 100, and uses the work identified by the acquired work ID as a work to be processed. (Step S24).

  In step S21, when the merchandising determination unit 115 determines that the product to be processed is a product to be processed (step S21; Yes), or after step S24, the relationship information storage unit 112r The product ID of the target product to be processed and the work ID of the target product to be processed are associated with each other and stored in the merchandising table TWM in FIG. Thereafter, the relationship information storage unit 112r ends the execution of the product information storage process.

  Here, web contents such as a home page explaining a certain work and contents explaining a product obtained by commercializing the work often include common contents. Therefore, according to these configurations, even if a product obtained by commercializing a work has a product name different from the work name of the work, the search result of the search engine 301 by the product name and the search engine by the work name Based on the degree of similarity with the search result 301, it is determined whether the product with the product name is a product obtained by commercializing the work with the product name. It is possible to accurately determine whether or not

  Since a product that commercializes a work is often described with the same web content along with the work, according to these configurations, the degree of coincidence between the search result by the work name keyword and the search result by the product name keyword Based on this, it is possible to accurately determine whether or not a product having a certain product name is a product obtained by commercializing a work having a work name.

  The search engine 301 usually assigns a higher display order to a content that is more likely to contain the content represented by the search keyword. Therefore, according to these structures, the location information with higher display order than the predetermined order included in the search result by the work name keyword and the display higher than the predetermined order included in the search result by the product name keyword It is possible to accurately determine whether or not a product with a certain product name is a product obtained by commercializing a work with a certain work name based on whether or not the location information with the ranking matches.

  A product name of a product obtained by commercializing a work is usually a name including words constituting the work name of the work. Therefore, according to these configurations, after searching for a work name including a word constituting a product name of a certain product, it is determined whether or not the product is a product obtained by commercializing a work having the searched work name. Therefore, as long as a common word is used for the work name and the product name, it is possible to determine whether or not the product with a certain product name is a product obtained by commercializing a work with a certain work name.

  In this embodiment, if the merchandising determination unit 115 determines that there is work name information representing a work name that completely matches the product name of the target product to be processed (step S14 in FIG. 5; Yes), the target product The process of step S16 for searching for work name information representing a work name including all of the words extracted from the product name (that is, the word matching work name), and a work name including a part of the extracted word (that is, In the above description, it is assumed that the process of step S18 for searching for work name information representing a partially matching work name is not executed. However, the present invention is not limited to this, and even if the merchandise determination unit 115 determines that there is work name information indicating a completely matching work name (step S14; Yes), step S16 and step S18. A plurality of pieces of work name information may be searched by executing one or more of the above processes.

  Further, in the present embodiment, the merchandising determination unit 115 in FIG. 6A performs the step in FIG. 7 when a plurality of pieces of work name information are searched in step S13, step S16, or step S18 in FIG. The work with the work name whose search result similarity calculated in S39 exceeds the threshold A in step S40 and is used for calculating the highest search result similarity is a work to be processed. It may be specified that the work to be processed is commercialized.

  Further, in this embodiment, the merchandising determination unit 115 in FIG. 6A, when a plurality of pieces of work name information are searched, search results similar to each piece of work name information in step S39 of FIG. It is possible to adopt a configuration that calculates the degree and transmits to the terminal device 201 work name information for which the calculated search result similarity exceeds the threshold A and information for instructing display of the work name information. In this configuration, the merchandising determination unit 115 acquires the work name information returned from the terminal device 201 from the information receiving unit included in the information processing apparatus 100 in FIG. 1B, and the processing target product is acquired. It may be determined that the work having the work name represented by the work name information is commercialized. In other words, the product to be processed is a product obtained by commercializing a work having the work name represented by the work name information selected by the user operating the terminal device 201 from the work name information whose search result similarity exceeds the threshold A. If so, the commercialization determination unit 115 may determine.

  The CPU 100a in FIG. 1B executes the product information storage process for storing the work information in the hard disk 100d as shown in FIG. 8, so that the work information acquisition unit 111w and the related information shown in FIG. It functions not only as the storage unit 112r but also as a content information acquisition unit 111c, a work information storage unit 112w, a content information storage unit 112c, a work name word extraction unit 113w, and a related work specifying unit 117 as shown in FIG. . The information storage unit 150 includes a work DB 150w, a product DB 150m, a relation DB 150r, a content DB 150c, and a pattern DB 150r shown in FIG.

  The relation DB 150r in FIG. 6B manages a related table TR that is stored in association with the work ID of the basic work and the work ID of the related work related to the basic work as shown in FIG. 4B. To do.

Here, reference works and related works will be described.
When a certain work is produced, a new work (hereinafter referred to as a derivative work) is produced from the produced work. For example, when a novel work is produced, a movie work that expresses the content expressed in the novel work in a movie is produced, and a music work that is used in the movie is produced as the movie work is produced. In addition, when a movie work is produced, a novelized work that makes the movie novel, and a cartoonized work that makes the movie cartoon.

  Therefore, if a certain movie work is a standard work, as shown in FIG. 2 (b), the original work that is the root of the standard work and a derivative work that is derived from the standard work (that is, novelize) Works, comics, and music) are fundamentally or derivatively related to the production of the reference work. For this reason, the original and derivative works of the standard work are called related works. A product obtained by commercializing a related work of the standard work as shown in FIG. 2B is referred to as a related product of the standard work.

  The content DB 150c in FIG. 6B stores the work ID stored in the work table TW in FIG. 3A in association with the content information representing the explanatory text describing the work identified by the work ID. . The content information is, for example, HTML (HyperText Markup Language) data.

  The pattern DB 150r is a pattern in which a description (hereinafter referred to as a specific description) used for specifying a related work related to the reference work is described in the explanatory texts respectively represented by a plurality of pieces of content information recorded in the content DB 150c. Is stored.

  The description pattern of the specific description represented by the pattern information stored in the pattern DB 150r includes a description pattern (hereinafter referred to as a related work specification description pattern) specifying a related work (hereinafter referred to as a related work specification description pattern), and a related work. Includes a description pattern (hereinafter referred to as a related product specification description pattern) of description (hereinafter referred to as a related product specification description) that specifies a related product that has been commercialized.

  For this reason, the pattern DB 150r includes a related work specifying description pattern table TPW in which pattern information representing the related work specifying description pattern as shown in FIG. 9A is stored, and a related product specifying as shown in FIG. 9B. The related product specific description pattern table TPM in which the pattern information indicating the description pattern is stored is managed.

  As a specific example, the description pattern “originally based on“ xxx ”” stored in the related-article specification description pattern table TPW in FIG. 9A is a basic work described in the description with the description pattern. Specifies that the work is created based on the related work with the work name “xxx”.

  In addition, the description pattern “live-action version DVD“ yyy ”of this work” stored in the related product specification description pattern table TPM in FIG. 9B is the basic work described in the description of the description pattern. It is specified that the product name of the DVD product obtained by commercializing the live-action version work (that is, the related work) is “yyy”.

  The description pattern “ISBNnnn-●-AAAA-BBBB-C” represents the description pattern of the ISBN code defined in the ISBN standard. Specifically, “nnn” is a predetermined number such as “978”, “●” is a number representing the publishing country, “AAAA” is a symbol representing the publisher, “BBBB” is a unique identification number for the publication, “C” represents a check digit. This ISBN description pattern specifies the product of the basic work described in the description in which the description pattern is written or the ISBN code of the related product described in relation to the description of the basic work.

Next, an example of the product information storage process executed using the above table will be described.
When the product information storage process of FIG. 8 is started, the work information acquisition unit 111w of FIG. 6B controls the information receiving unit so as to receive the detailed work information including the work name information from the terminal device 201, and then the information Detailed work information is acquired from the receiver (step S51).

  Next, the work information storage unit 112w generates a work ID for identifying the work, and then associates the generated work ID with the detailed work information acquired in step S51 to obtain work information. Thereafter, the work information storage unit 112w stores the work information in the work table TW in FIG. 3A (step S52).

  Thereafter, the work name word extraction unit 113w extracts words constituting the work name from the work name, for example, by morphological analysis. Next, the content information acquisition unit 111c sets a work name or a keyword generated from the work name as a search keyword for content information (step S53). The keyword generated from the work name includes a word extracted from the work name.

  Next, based on the set search keyword, the content information acquisition unit 111c searches the DB of the Web server 302 for content information that describes the work name of the search keyword or the work name used to generate the search keyword. Search is performed (step S54). Next, the content information acquisition unit 111c acquires the received content information from the information reception unit after controlling the information reception unit included in the information processing apparatus 100 so as to receive the searched content information from the Web server 302. (Step S55). Next, the content information storage unit 112c stores the work ID in step S52 and the content information acquired in step S55 in association with each other in the content DB 150c (step S56).

  Next, the related work specifying unit 117 acquires pattern information from the pattern DB 150p (step S57). Thereafter, the related work specifying unit 117 determines whether or not the related work specifying description pattern represented by the acquired pattern information can be detected from the explanatory text represented by the content information acquired in Step S55 (Step S58). ). At this time, when the related work specifying unit 117 determines that the related work specifying description pattern has been detected (step S58; Yes), the related work specifying unit 117 extracts the related work specifying description pattern from the explanatory text represented by the content information. (Step S59). The related work specifying unit 117 specifies the work name of the related work based on the extracted related work specifying description pattern, and then searches the work ID from the work table TW of FIG. 3A based on the specified work name. (Step S60).

  If it is determined in step S58 that the related work specifying description pattern cannot be detected (step S58; No), the related work specifying unit 117 determines whether or not the related product specifying description pattern can be extracted from the explanatory text represented by the content information. A determination is made (step S61). At this time, if the related work specifying unit 117 determines that the related product specifying description pattern cannot be detected (step S61; No), the related work specifying unit 117 ends the execution of the work information storing process.

  On the other hand, if it is determined that the related product specific description pattern can be detected (step S61; Yes), the related work specifying unit 117 extracts the related product specific description pattern from the explanatory text represented by the content information (step S62). ). The related work specifying unit 117 specifies the product name or ISBN code of the related product based on the extracted related product specification description pattern, and then the product shown in FIG. 3B based on the specified product name or ISBN code. The product ID is searched from the table TM (step S63). Next, the related work specifying unit 117 searches for the work ID from the merchandising table TWM of FIG. 4A based on the searched product ID (step S64).

  After step S60 or step S64, the relationship information storage unit 112r sets the work ID generated in step S52 as the work ID of the basic work, and sets the work ID searched in step S60 or step S64 as the work ID of the related work. Next, the related information storage unit 112r associates the work ID of the basic work and the work ID of the related work and stores them in the related table TR of FIG. 4B (step S65). Thereafter, the relationship information storage unit 112r ends the work information storage process.

  Here, for example, web content that is permitted to be edited by an unspecified user, such as Wikipedia (registered trademark), is edited by an unspecified user. While easy to edit, structurally structured content such as Wikipedia (registered trademark) InfoBox or DBpedia is difficult to edit quickly and accurately. Therefore, according to these configurations, in order to identify a related work from the description of the web content that an unspecified user is permitted to edit based on the description pattern of the related work, when a new work is created, The related work of the created work can be quickly and accurately identified.

  Since works are usually distributed as commercialized products, it is better to specify the product of the work than to specify the work itself in the web content that the unspecified user is allowed to edit. It is easy to publish quickly and accurately. For this reason, according to these structures, since the related work is specified based on the specified related product after specifying the related product of a certain work, the related work of the work can be specified quickly and accurately.

  The CPU 100a in FIG. 1B executes the series work group specifying process for specifying the series work group as shown in FIG. 10, whereby the relation information storage unit 112r and the work information search shown in FIG. Unit 114w, display control unit 116, and content information acquisition unit 111c shown in FIG. 6B, content word extraction unit 113c, content similarity calculation unit 120, content information classification unit as shown in FIG. 121 and the series work group identification unit 122.

Here, the series works will be described.
The series work group is a work group composed of a plurality of series works (hereinafter referred to as series works). Here, the series work is a main work and related works that are derived from the main work such as a sequel to the main work, a live-action version / animation version, or a foreign work, for example. Those with common characteristics. Features common to the main work include, for example, the same kind of work as the main work, and the appearance of characters in common with the characters of the main work.

  The related DB 150r of the information storage unit 150 illustrated in FIG. 11 further manages the series table TS as illustrated in FIG. This series table TS includes a series work group ID for identifying a series work group, series work name information indicating a work name of the series work (hereinafter referred to as a series work name), and one or more series constituting the series work group. The work IDs of the works (hereinafter referred to as series work IDs) are stored in association with each other.

  When the series work group specifying process of FIG. 10 is started, the content information acquisition unit 111c acquires a plurality of work IDs and content information stored in association with each other in step S56 of FIG. 8 from the content DB 150c (step S71). . Next, the content similarity calculation unit 120 detects the description pattern of the URL that indicates the location of the image and the content information that represents the image that is referred to in order to describe the work, from the description that is represented by each of the plurality of content information Then, the URL is extracted from the explanatory text in which the description pattern is detected (step S72). After that, the content word extraction unit 113c extracts words constituting each explanatory sentence by executing, for example, morphological analysis from the explanatory sentences respectively represented by the plurality of pieces of content information (step S73). After that, the content similarity calculation unit 120 extracts the content similarity representing the degree of similarity with other explanatory texts for each of the explanatory texts of the plurality of content information acquired in step S71, and the URL extracted in step S72. And based on any one or more of the words extracted in step S73 (step S74).

  As a specific example, the content similarity calculation unit 120 occupies a plurality of URLs extracted from explanatory texts represented by other content information in a plurality of URLs extracted from explanatory texts represented by certain content information. The proportion of URLs that match any one of them may be the content similarity.

  In addition, the content similarity calculation unit 120 is, for example, a uniqueness extracted from an explanatory sentence represented by other content information that occupies a plurality of words representing a proper noun extracted from an explanatory sentence represented by certain content information. The ratio of URLs that match any of a plurality of words representing nouns may be used as the content similarity. In addition, the content similarity calculation unit 120 is a word that represents a feature of a work (for example, a word that represents a cast such as “actor” or “actress”) among words extracted from explanatory text represented by certain content information. , The word “director”, or the word “screenplay”), the word representing the proper noun before or after the predetermined word is extracted from the explanatory text represented by other content information. The content similarity may be a ratio that matches a word representing a proper noun before or after a predetermined word from a word representing.

  After step S74, the content information classification unit 121 classifies the content information into a plurality of content groups (that is, clusters) by clustering the content information based on the calculated content similarity (step S75).

  Next, the series work group specifying unit 122 determines whether or not the processing from step S77 to step S87 has been executed for all the groups (clusters) (step S76). At this time, if the series work group specifying unit 122 determines that the processing has not been executed for all the clusters (Step S76; No), one of the unprocessed groups (clusters) is set as a processing target (Step S76). S77). Next, the series work group specifying unit 122 is configured by a plurality of works each described in the description of a plurality of pieces of content information constituting a cluster to be processed (hereinafter referred to as a target group or a target cluster in this flow). Are identified as a series work group (step S78).

  The series work group specifying unit 122 searches the content DB 150c for a work ID associated with the content information constituting the target group (target cluster) (step S79). Next, the series work group specifying unit 122 determines whether or not the processing of the following step S81 and step S82 has been executed for all searched work IDs (step S80). At this time, if it is determined that the process has been executed for all the searched work IDs, the series work group specifying unit 122 repeats the above process from step S76. On the other hand, if it is determined that the processing has not been executed for all the searched work IDs, the series work group specifying unit 122 sets one unprocessed work ID as a processing target (step S81).

  Next, the series work group specifying unit 122 uses the same work ID as the work ID to be processed (hereinafter referred to as the target work ID in this flow) as the basic work ID string in the related table TR shown in FIG. And the related work ID string is searched (step S82). Thereafter, the series work group specifying unit 122 determines whether or not the work ID has been searched from the related table TR (step S83). At this time, if the series work group specifying unit 122 determines that the work ID could not be searched (step S83; No), the process returns to step S80 and repeats the above processing. This is because a plurality of series works constituting a series work group are either main works or related works of the main work, and therefore there are always related works. On the other hand, when the series work group specifying unit 122 determines that the reference work ID has been searched (step S83; Yes), the work associated with the searched work ID in the related table TR in FIG. 4B. An ID (that is, a work ID of a related work related to the work identified by the searched work ID) is acquired (step S84).

  Next, the series work group specifying unit 122 determines whether the work ID of the acquired related work is a work ID associated with the content information constituting the target group (target cluster) (that is, the same series work group is selected). It is determined whether or not it is a work ID of a work to be configured (step S85). At this time, if the series work group specifying unit 122 determines that the acquired work ID of the related work is not the work ID of the work constituting the same series work group, the above-described processing is repeated from step S80. This is because the series works always have related works that make up the same series. In contrast, when the series work group specifying unit 122 determines that the work ID of the acquired related work is the work ID of a work that constitutes the same series work group (step S85; Yes), the series work group specifying unit 122 is set as a processing target. The work identified by the work ID (hereinafter referred to as the target work in this flow) and the related work of the target work identified by the work ID acquired in step S84 are identified in step S79 as a series work group. It is specified that it is a series work constituting the target group (target cluster) (step S86). Thereafter, the relationship information storage unit 112c adds a target group ID for identifying the target group (target cluster) (that is, a series work group ID for identifying the series work group) and the target work to the series table TR in FIG. And the target work ID (that is, the series work ID for identifying the series work) are stored in association with each other (step S87). The related information storage unit 112c may further store the target group ID and the related work ID acquired in step S84 in association with each other. Thereafter, the relationship information storage unit 112c repeats the above process from step S80.

  The relation information storage unit 112c extracts a common partial character string from the work names of a plurality of series works, uses the extracted character string as the name of the series work group, and series work group name information indicating the name of the series work group And the series work group ID may be stored in association with each other. For example, as shown in FIG. 4C, the work names “XX Man (live-action version 1)” of the works identified by the series work IDs “W002” to “W004” and “W008” to “W010”, “ XX Man (Live Action Version 2), XX Man (Live Action Version 3), XX Man (Anime Version 1), XX Man (Anime Version 2), and XX Man (Anime) The character string “XX Man” common to “version 3)” may be used as the name of the series work group.

  In addition, in step S74, the relationship information storage unit 112c represents a proper noun before or after a predetermined word from a word representing the feature of the work used to calculate the content similarity (for example, the word “director”). The name of the series work group may be generated using the words extracted by the content similarity calculation unit 120. For example, the relationship information storage unit 112c may set the name of the series work group composed of movie works produced by the director “John Doe” as “John Doe Director Work Series”.

  In step S76, when the series work group specifying unit 122 determines that the processing has been executed for all the clusters (step S76; Yes), the display control unit 116, for example, a series as illustrated in FIG. The terminal device 201 is controlled to display the work display screen FSW on the display unit. Next, the display control unit 116 retrieves the series work group name information from the series table TS in FIG. 4C, and the retrieved series work group name information is associated with the series work group name information. Search multiple series titles. Thereafter, the display control unit 116 associates the name of the series work group represented by the searched series work group name information with the series work name represented by the searched series work name information, and displays the series work display screen. The terminal device 201 is controlled to display on the FSW (step S88). Specifically, the display control unit 116 transmits the series work group name information, the series work name information, and information for instructing to display the names represented by these pieces of information in association with each other to the terminal device 201. The information transmission unit included in the information processing apparatus 100 is controlled.

  Next, the display control unit 116 controls the terminal device 201 to display, for example, a series product display screen FSM as shown in FIG. 12B on the display unit. Thereafter, the display control unit 116 searches for the product ID and product name information associated with the work ID of the series work from the commercialization table TS of FIG. Next, the display control unit 116 associates the name of the series work group and the product name of the product name of the product represented by the searched product name information, and displays them on the series product display screen FSM. 201 is controlled (step S89). Specifically, the display control unit 116, the series work group name information, the product name information of the series product that commercializes the series work, and the information that commands to display the names represented by these information in association with each other. Is transmitted to the terminal device 201. Thereafter, the display control unit 116 ends the execution of the series work group specifying process.

  Here, since the series works constituting the series work group have, for example, many characters, common backgrounds, stories, etc., the descriptions of the series works constituting the same series work group are similar to each other. Therefore, according to these configurations, it is possible not only to accurately identify the series work group from the classification of the explanatory text based on the similarity indicating the degree of similarity of the work, but even if a new series work is created. , It is possible to quickly and accurately identify which series works the created work constitutes.

  In addition, since the series works have many similarities such as characters, period backgrounds, and stories, for example, the description of the main work and the description of the series work include common characters, period backgrounds, and stories. Has similar words, images, links, etc. to explain. Therefore, according to these structures, a series work group can be pinpointed correctly based on the classification | category of the description based on the similarity which represents the degree which the word and image and these locations resemblance | analogue.

  Furthermore, according to these configurations, when works in the same work group composed of works with similar descriptions are related to each other, the related works are identified as series works. Series works can be identified.

  The CPU 100a in FIG. 1B detects the possibility of an error in the correspondence between the work ID and the product ID stored in the merchandising table TWM as shown in FIG. 13A. Is executed, not only the product information search unit 114w shown in FIG. 6A, but also functions as a product information search unit 114m, an error detection unit 125, and a warning unit 126 as shown in FIG. The work information search unit 114w and the product information search unit 114m constitute an information search unit 114.

  When the first error detection process in FIG. 13A is started, the product information search unit 114m searches for a plurality of product IDs from the product table TM in FIG. Next, the work information search unit 111w determines whether or not the processing from step S92 to step S98 has been executed for all of the searched product IDs (step S91). At this time, if the work information search unit 111w determines that the processing has not been executed for all the searched product IDs (Step S91; No), one of the unprocessed product IDs is set as a processing target (Step S91). S92). Next, the work information search unit 111w searches for the work ID from the commercialization table TS of FIG. 4A based on the product ID targeted for processing (hereinafter referred to as the target product ID in this flow) (step S93). ). This is because the work ID of the work provided by the product identified by the product ID is searched.

  Next, the work information search unit 111w determines whether or not the processing of step S95 and step S96 has been executed for all of the searched work IDs (step S94). At this time, if the work information search unit 111w determines that the process has not been executed for all searched work IDs (step S94; No), one of the unprocessed work IDs is set as a processing target (step S94). S95). Thereafter, the work information search unit 111w searches for the series work group ID from the series table TS of FIG. 4C based on the work ID (hereinafter referred to as the target work ID in this flow) that is the processing target (step). S96). This is because the ID of the series work group constituted by the work identified by the target work ID is searched. Thereafter, the work information search unit 111w returns to Step S94 and repeats the above processing.

  In step S94, when the work information search unit 111w determines that the processing has been executed for all searched work IDs (step S94; Yes), the error detection unit 125 determines the series of series works searched in step S96. It is determined whether or not there are a plurality of work group IDs (step S97). At this time, if the error detection unit 125 determines that a plurality of series work group IDs of the series work group searched in step S96 does not exist (that is, only one) (step S97; No), the step Returning to S91, the above processing is repeated. On the other hand, when the error detection unit 125 determines that there are a plurality of searched series work group IDs (step S97; Yes), the warning unit 126 sets the target in the productization table TWM in FIG. The terminal device 201 is controlled so as to warn of the possibility that there is an error in the correspondence between the product ID and the target work ID (step S98). As a specific example, the warning unit 126 may control the terminal device 201 to display on the display unit a message warning that there is a possibility that the correspondence between the target product ID and the target work ID is incorrect. You may control the terminal device 201 so that an audio | voice may be output. That is, the warning unit 126 sends information indicating a message or sound that warns the possibility that there is an error in correspondence between the target product ID and the target work ID, and information that instructs the display of the message or output of the sound to the terminal device 201. The information transmitting unit is controlled to transmit. Then, it returns to step S91 and the said process is repeated.

  When the warning unit 126 warns that there is an error in correspondence, the display control device 116 in FIG. 6A inputs a work ID associated with the target product ID that warned that there is an error in correspondence. The terminal device 201 may be controlled to display a message prompting the user to do so. 6A associates the work ID received from the terminal device 201 with the target product ID after the display control device 116 performs display control of the message. It may be stored in the merchandising table TWM of 4 (a).

  In step S91, when the work information search unit 111w determines that the process has been executed for all the searched product IDs (step S91; Yes), the execution of the first error detection process is terminated.

  For example, one DVD box that combines multiple DVDs that record multiple DVDs that make up the same series of movies on a single DVD, or records the DVDs on different DVDs. However, it is rare that a plurality of works constituting a different series work group or different from the series work are commercialized as the same product. Therefore, according to these structures, based on the determination result of whether there is a plurality of series work group identification information searched for one product identification information, the product identification information is associated with the series work identification information. It is possible to detect that there may be an error.

  The CPU 100a in FIG. 1 (b) performs the basic work ID (hereinafter referred to as basic work ID) and the related work ID (hereinafter referred to as related works) stored in the related table TR as shown in FIG. 13 (b). A second error detection process for detecting the possibility of an error in association with ID) is further executed.

  When the second error detection process in FIG. 13B is started, the work information search unit 114w searches for a plurality of work IDs from the work table TW in FIG. Next, the work information search unit 111w determines whether or not the processing from step S102 to step S108 has been executed for all of the searched work IDs (step S101). At this time, if the work information search unit 111w determines that the processing has not been executed for all searched work IDs (Step S101; No), one of the unprocessed work IDs is set as a processing target (Step S101). S102). Next, the work information search unit 111w performs the basic work ID column and the related work ID column of the related table TR in FIG. 4B based on the work IDs to be processed (hereinafter referred to as the target work IDs in this flow). The work ID is searched from (step S103). This is to search for works related to the work identified by the target work ID.

  Next, the work information search unit 111w determines whether or not the processing of step S105 and step S106 has been executed for all of the searched work IDs (step S104). At this time, when the work information search unit 111w determines that the process has not been executed for all searched work IDs (Step S104; No), the same process as Step S95 and Step S96 of FIG. Is executed (step S105 and step S106). Thereafter, the work information search unit 111w returns to step S104 and repeats the above processing.

  In step S104, when the work information search unit 111w determines that the processing has been executed for all searched work IDs (step S104; Yes), the error detection unit 125 determines that the series work group ID searched in step S106 is the same. It is determined whether or not there are a plurality (step S107). At this time, if the error detection unit 125 determines that there are not a plurality of series work group IDs searched in step S106 (that is, only one) (step S107; No), the error detection unit 125 returns to step S101 and returns to the above Repeat the process. On the other hand, when the error detection unit 125 determines that there are a plurality of searched series work group IDs (step S107; Yes), the warning unit 126 displays the basic work in the related table TR in FIG. The terminal device 201 is controlled so as to warn of the possibility that there is an error in correspondence between the ID and the related work ID (step S108). Then, it returns to step S101 and the said process is repeated.

  As in the first error warning process, when the warning unit 126 warns that there is a possibility of an error in correspondence, the display control device 116 in FIG. The terminal device 201 may be controlled to display a message prompting the user to input a work ID associated with either the basic work ID or the related work ID. Further, the relation information storage unit 112r in FIG. 6A performs a terminal device for the basic work ID or the related work ID received from the terminal device 201 after the display control device 116 performs display control of the message. The work IDs received from 201 may be associated with each other and stored in the related table TR in FIG.

  In step S101, when the work information search unit 111w determines that the process has been executed for all searched work IDs (step S101; Yes), the execution of the second error detection process is terminated.

  Here, for example, a series work such as a sequel work, a live-action version work, or a foreign work is created in a derivative manner from the main work, and the series work is further created in a derivative manner from the series work. For this reason, the series works are works each having a relation (that is, a derivative relation or a root relation). Therefore, according to these configurations, based on the determination result of whether or not there are a plurality of series work group identification information searched for information identifying the related work of one series work, the relation to the series work identification information is determined. It can be detected that there is a possibility that there is an error in the correspondence of the work identification information.

  The CPU 100a in FIG. 1B performs a third error detection process for detecting a possibility that there is an error in the correspondence between the series work ID and the series work group ID stored in the series table TS as shown in FIG. And run further.

  When the third error detection process of FIG. 15 is started, the work information search unit 114w searches for a plurality of series work group IDs from the series table TS of FIG. Next, the work information search unit 111w determines whether or not the processing from step S112 to step S118 has been executed for all of the searched series work group IDs (step S111). At this time, when the work information search unit 111w determines that the processing has not been executed for all the searched series work group IDs (step S111; No), one of the unprocessed series work group IDs is processed. (Step S112). Next, the work information search unit 111w searches for the series work ID of the series table TS in FIG. 4C based on the series work group ID to be processed (hereinafter referred to as the target series work group ID in this flow). (Step S113). This is because the work IDs of the series works constituting the series work group identified by the target series work group ID are searched.

  Next, the work information search unit 111w determines whether or not the processing of step S115 and step S116 has been executed for all of the searched series work IDs (hereinafter referred to as search work IDs in this flow) (step S114). ). At this time, if the work information search unit 111w determines that the processing has not been executed for all the searched series work IDs (step S114; No), the unprocessed search work ID (that is, the searched series work ID). ID) is set as a processing target (step S115). Next, the work information search unit 111w, based on the work ID to be processed (hereinafter referred to as the target work ID in this flow), from the work table TW in FIG. Is searched (step S116). Thereafter, the work information search unit 111w returns to Step S114 and repeats the above processing.

  In step S114, when the work information search unit 111w determines that the processing has been executed for all the searched series work IDs (step S114; Yes), the error detection unit 125 detects the work of the series work searched in step S116. It is determined whether or not there are a plurality of types (hereinafter referred to as search work types in this flow) (step S117). At this time, if the error detection unit 125 determines that there are not a plurality of types of search works searched in step S106 (that is, only one type) (step S117; No), the error detection unit 125 returns to step S111 and returns to the above Repeat the process. On the other hand, when the error detection unit 125 determines that there are a plurality of types of the searched series works (step S117; Yes), the warning unit 126 in the series table TR of FIG. 4C. The terminal device 201 is controlled so as to warn of a possibility that there is an error in correspondence between the series work group ID and the series work ID (step S118). Then, it returns to step S111 and the said process is repeated.

  As in the first error warning process, when the warning unit 126 warns that there is a possibility of an error in correspondence, the display control device 116 in FIG. The terminal device 201 may be controlled to display a message prompting the user to input a series work ID associated with the series work group ID or a series work group ID associated with the series work ID. Further, the relation information storage unit 112r in FIG. 6A performs terminal processing on the series work group ID or series work ID received from the terminal device 201 after the display control device 116 performs display control of the message. The series work ID or series work group ID received from the device 201 may be associated with each other and stored in the series table TS of FIG.

  In step S111, when the work information search unit 111w determines that the process has been executed for all the searched series work IDs (step S111; Yes), the execution of the third error detection process is terminated.

  Here, for example, as a sequel to a certain movie work is created as a movie work, the series works constituting the same series work group often have the same work type. Therefore, according to these configurations, there is an error in associating the series work identification information with the series work group information based on whether or not there are a plurality of pieces of work type information searched for one series work group information. Detect possible.

  The CPU 100a in FIG. 1B executes the preference specifying process for specifying the preference of the user of the information processing system 1 as shown in FIG. 16, so that the work information search unit 114w shown in FIG. 14 functions as a user information search unit 114u, a preference specifying unit 130, a preference determination unit 131, and a user information storage unit 112u as shown in FIG. The product information search unit 114m, the work information search unit 114w, and the user information search unit 114u constitute an information search unit 114. Furthermore, the information storage unit 150 in FIG. 17 includes a work DB 150w and a product DB 150m, and a user DB 150u in FIG.

  As shown in FIG. 18A, the user DB 150u is stored in association with a user ID for identifying the user and attribute information including information representing the user's name, information representing the age, and information representing the gender. Manage the user table TU. The attribute information further includes information representing the user's residence area and information representing the occupation.

  Further, the user DB 150u, as shown in FIG. 18B, a user ID for identifying the user, for example, information indicating a purchase date of the product, and a work ID of the work provided to the user by the purchased product. Is managed in the history table TH in which the purchase history information associated with is stored. Note that the information stored in the history table TH is not limited to purchase history information. For example, trailer viewing information in which information indicating the viewing date of a trailer video is associated with a work ID viewed by the user. It may be.

  Furthermore, the user DB 150u manages a preference table TP that is stored in association with the user ID of the user and preference information representing the feature of the work that matches the user preference, as shown in FIG. Here, the feature of the work that matches the user's preference is, for example, work detailed information indicating the work type, production country, cast, director, screenwriter, work time, release year, artist, songwriter, composer, etc. It is represented by For example, users who like anime, users who like Korean dramas, users who like American dramas, users who are fans of specific actors or actresses, users who like works directed by specific directors, users who like short films, classics This is because there are users who like the work.

  Also, the user DB 150u, as shown in FIG. 18D, the user ID of the user, the series work group ID of the series work group, information indicating the name of the series work group, and the series work according to the user's preference. A series work group discrimination result table TSG stored in association with information indicating the discrimination result for discriminating whether or not the groups match is managed.

  Furthermore, as shown in FIG. 18E, the user DB 150u stores the user ID of the user, the series work group ID of the series work group, the work ID of the series work that constitutes the series work group, and the work of the series work. A series work discrimination result table TSW stored in association with name information and information representing a discrimination result obtained by discriminating whether or not the series work matches the user's preference is managed.

  Further, the user DB 150u, as shown in FIG. 18 (f), the user ID of the user, the series work group ID of the series work group, the work ID of the series work constituting the series work group, and the series work Related work discrimination result table in which the work ID of the related work, the work name information of the related work, and information representing the discrimination result that discriminates whether or not the related work matches the user's preference are stored in association with each other. Manage the TRW.

Next, an example of preference specifying processing executed using the above table will be described.
When the execution of the preference specifying process in FIG. 16 is started, the user information search unit 114u acquires a plurality of user IDs from the user table TU in FIG. 18A, and then performs steps S132 to S138 for all the acquired user IDs. It is determined whether or not the process has been executed (step S131). At this time, if the user information search unit 114u determines that the processing has not been executed for all the user IDs (step S131; No), one of the unprocessed user IDs is set as a processing target (step S132).

  Next, the user information search unit 114u, based on the user ID to be processed (hereinafter referred to as the target user ID in this flow), works of works provided to the user from the history table TH in FIG. ID (hereinafter referred to as provided work ID in this flow) is searched (step S133).

  Next, the work information search unit 114w determines whether or not the processes of Step S135 and Step S136 have been performed for all the provided work IDs that have been searched (Step S134). At this time, when the work information search unit 114w determines that all the provided work IDs have not been processed (step S134; No), one of the unprocessed provided work IDs is set as a processing target ( Step S135). Next, the work information search unit 114w searches for feature information characterizing the work from the work table of FIG. 3A based on the provided work ID (hereinafter referred to as the target work ID in this flow) as the processing target. (Step S136).

  In step S134, when the work information search unit 114w determines that all provided work IDs have been processed (step S134; Yes), the preference specifying unit 130 is represented by the feature information searched in step S136. Based on the common feature, the feature of the work that matches the preference of the user identified by the target user ID is specified (step S137).

  As a specific example, the preference specifying unit 130 may specify a feature common to a predetermined number or more works as a feature of the work that matches the user's preference. For example, it is because a user whose animation work does not meet his / her preference rarely purchases or rents a predetermined number or more of products of the animation work. In addition, the preference specifying unit 130 may specify, among the works provided by the user, the characteristics that the works exceeding a predetermined ratio have in common as the characteristics of the works that match the user's preference.

  After step S137, the user information storage unit 112u associates the preference information representing the feature identified as matching the user preference in step S137 with the user ID of the user in the preference table TP in FIG. Save (step S138). Thereafter, the process returns to step S131 and the above process is repeated.

  In step S131, when the user information search unit 114u determines that the process has been executed for all user IDs (step S131; Yes), the execution of the preference specifying process is terminated.

  The CPU 100a in FIG. 1B further performs a first preference determination process for determining whether or not the series work and the series work group constituted by the series work match the user's preference as shown in FIG. Execute.

  When the execution of the first preference determination process in FIG. 19 is started, the user information search unit 114u acquires a plurality of user IDs from the user table TU in FIG. It is determined whether or not the process of S151 has been executed (step S141). At this time, if the user information search unit 114u determines that the processing has not been executed for all the user IDs (step S141; No), one of the unprocessed user IDs is set as a processing target (step S142). Next, the user information search unit 114u searches the preference information from the preference table TP in FIG. 18C based on the user ID that is the processing target (hereinafter referred to as the target user ID in this flow) (step S143). .

  Next, after acquiring the series work group ID from the series table TS, the work information search unit 114w determines whether or not the processing from step S145 to step S151 has been executed for all the acquired series work group IDs ( Step S144). At this time, if the work information search unit 114w determines that the processing has not been executed for all series work group IDs (step S144; No), one of the unprocessed series work group IDs is set as a processing target ( Step S145). Next, the work information search unit 114w searches for the series work ID from the series table of FIG. 4C based on the series work group ID to be processed (hereinafter referred to as the target group ID in this flow) (step). S146). This is because the work IDs of the series works constituting the series work group identified by the target group ID are searched. Next, the work information search unit 114w searches for the feature information of the series work based on the searched series work ID (searched work ID) from the work table TW (step S147).

  Thereafter, the preference discriminating unit 131 determines that each of the series works constituting the target group (the series work group to be processed) based on the preference information searched in step S143 and the feature information searched in step S147. Then, it is determined whether or not the user's preference identified by the target user ID is met (step S148).

  As a specific example, the preference discriminating unit 131 has a feature similarity indicating the degree of similarity between the feature represented by the feature information of the series work and the feature of the work that matches the user's preference represented by the preference information. When the predetermined threshold B is exceeded, it is determined that the user's preference is met. The feature similarity may be, for example, the ratio of the number of features that match the feature represented by the feature information that the series works have in common to the number of features that match the user's preference represented by the preference information. good. The threshold value B is stored in the information storage unit 150.

  After step S148, the user information storage unit 112u includes the target user ID, the series work group ID of the target group, the series work ID of the series work constituting the target group, and the determination result information indicating the determination result of step S148. Are stored in the series work determination result table TSW of FIG. 18E (step S149).

  Thereafter, the preference determination unit 131 identifies the target group (the series work group to be processed) by the target user ID based on the preference information searched in step S143 and the feature information searched in step S147. It is determined whether or not the user's preference is met (step S150).

  As a specific example, the preference discriminating unit 131, when the ratio of the number of series works determined to match the user's preference in step S148 with respect to the number of series works constituting the series work group exceeds a predetermined threshold C Moreover, you may discriminate | determine that the said series work group matches a user preference. The threshold value C is stored in the information storage unit 150.

  After step S150, the user information storage unit 112u associates the target user ID, the series work group ID of the series work group that is the target group, and the determination result information indicating the determination result of step S148, as shown in FIG. It is stored in the series work group discrimination result table TSG of d) (step S151). Thereafter, the above process is repeated from step S144.

  If it is determined in step S144 that the work information search unit 114w has executed the process for all series work group IDs (step S144; Yes), the above process is repeated from step S141.

  In step S141, when the user information search unit 114u determines that the process has been executed for all user IDs (step S141; Yes), the execution of the first preference determination process ends.

  According to these configurations, based on the features of the work that matches the user's preference and the characteristics of the series work, it is accurately determined whether or not the series work group composed of the series work matches the user's preference. Can be determined.

  According to these configurations, it is possible to accurately determine whether or not the series work matches the user's preference based on the feature of the work that matches the user's preference and the feature of the series work.

  The CPU 100a in FIG. 1B further executes a second preference determination process for determining whether or not the related work of the series works matches the user's preference as shown in FIG.

  When the execution of the second preference determination process in FIG. 20 is started, the same processes as in steps S141 to S146 in FIG. 20 are executed (steps S161 to S166). After step S166, the work information search unit 114w searches the basic work ID column and the related work ID column of the related table TR in FIG. 4B for the same work ID as the searched series work ID. Next, the work information search unit 114w sets the work ID associated with the searched work ID as the related work ID of the work identified by the searched work ID (step S167). Thereafter, the work information search unit 114w searches for the feature information of the related work from the work table TW in FIG. 3A based on the related work ID (step S168).

  Based on the preference information searched in step S163 and the feature information searched in step S168, the preference discriminating unit 131 determines that related works related to the series works constituting the series work group that is the target group are the target users. It is determined whether or not the user's preference identified by the ID matches (step S169).

  After that, the user information storage unit 112u displays the target user ID, the series work group ID of the series work group that is the target group, the work ID of the series work constituting the target group, and the related work related to the series work. The ID and the discrimination result information representing the discrimination result in step S169 are associated with each other and stored in the related work discrimination result table TRW in FIG. 18 (f) (step S170). Thereafter, the above process is repeated from step S164.

  In step S164, when the work information search unit 114w determines that the process has been executed for all the series work group IDs (step S164; Yes), the above process is repeated from step S161.

  In step S161, when the user information search unit 114u determines that the process has been executed for all user IDs (step S161; Yes), the execution of the second preference determination process ends.

  According to these configurations, it is possible to accurately determine whether the related work related to the series work matches the user's preference based on the feature of the work that matches the user's preference and the feature of the related work.

  As shown in FIG. 17, the CPU 100 a in FIG. 1B executes a favorite work specifying process for specifying a work that matches the user's preference as shown in FIG. 21 based on the preference of another user. Functions as a favorite work specifying unit 132 or the like.

  Note that the user DB 150u stores a user ID for identifying a user and a work ID of a work that matches the user's preference (hereinafter referred to as a favorite work) as shown in FIG. Manage your favorite work table.

  When the execution of the favorite work specifying process in FIG. 21 is started, the user information search unit 114u acquires the user ID from the user table TU in FIG. 18A, and then performs steps S182 to S193 for all the acquired user IDs. It is determined whether the process has been executed (step S181). At this time, if the user information search unit 114u determines that the processing has not been executed for all the user IDs (step S181; No), one of the unprocessed user IDs is set as a processing target (step S182).

  Next, the user information search unit 114u, based on the user ID to be processed (hereinafter referred to as the target user ID), from the history table of FIG. In the flow, the provided work ID is searched (step S183).

  Next, the user information search unit 114u is identified by the target user ID from the history table TH of FIG. 18B based on the searched provided work ID in order to identify other users who have been provided with the same work. A user ID (hereinafter referred to as another user ID in this flow) of a user (hereinafter referred to as other user in this flow) different from the target user to be searched is searched (step S184). Thereafter, the user information search unit 114u searches for preference information representing features common to works that match the preferences of other users from the preference table TP of FIG. 18B based on the other user IDs that have been searched. (Step S185). Next, the user information search unit 114u similarly searches for preference information based on the target user ID (step S186). Thereafter, the preference work specifying unit 132 selects the target user and the other user based on the preference information of the other user searched in step S1845 and the preference information of the target user identified by the target user ID searched in step S186. The preference similarity with the user is calculated (step S186).

  Here, the preference similarity between the target user and other users is an index representing the degree of similarity between the features of the works that match the preferences of the target users and the features of the works that match the preferences of other users. is there. This index may be, for example, the ratio of the number of features common to the target user's favorite works and other users' favorite works to the number of features of the target user's favorite works.

  After step S187, the preference work specifying unit 132 determines whether the preference similarity is equal to or higher than a predetermined threshold D (step S188). The predetermined threshold value D is stored in the information storage unit 150. At this time, when the preference work specifying unit 132 determines that the preference similarity is smaller than the threshold value D (step S188; No), the above steps are repeated from step S181. This is because other users having a preference similar to that of the target user could not be detected.

  On the other hand, if the preference work specifying unit 132 determines that the preference similarity is equal to or greater than the threshold value D (step S188; Yes), based on the preference information of other users searched in step S184, A work ID of a work having a feature represented by other user's preference information is searched from the work table TW in FIG. 3A (step S189). Thereafter, the favorite work specifying unit 132 searches for the work ID searched in step S189 from the history table TH of FIG. 18B based on the other user ID (step S190). This is to search for works that match the tastes of other users and that are provided with products purchased by other users. Thereafter, the favorite work specifying unit 132 determines whether or not a work ID has been searched (step S191). At this time, if it is determined that the work ID has been searched (step S191; Yes), the favorite work specifying unit 132 specifies the work identified by the searched work ID as the target user's favorite work (step S192). ). Thereafter, the user information storage unit 112u in FIG. 17 associates the target user ID with the identified work ID of the favorite work and stores it in the favorite work table TP in FIG. 18G (step S193). Thereafter, the above process is repeated from step S181.

  In step S181, when the user information search unit 114u determines that the process has been executed for all the user IDs (step S181; Yes), the execution of the favorite work specifying process ends.

  Here, since the user usually obtains a product that provides a work that matches the user's preference, according to these configurations, the first user's product acquisition history or the work provision history for the first user is represented. Even if not enough information is stored, the second user who has obtained the same product as the product provided by the product obtained by the first user (whether or not the product is the same as the product obtained by the first user) Based on the preference, the preference of the first user can be specified.
