  The storage unit 12 includes, for example, a hard disk drive, and stores various programs such as an operating system and a server program. Note that the various programs may be acquired from, for example, another server device or the like via the network NW, or may be recorded on a recording medium and read via the drive device.

  The storage unit 12 includes a book DB 121, a user comment DB 122, a user comment positive / negative DB 123, a positive / negative determination dictionary 124, a display order determination dictionary 125, a difficulty determination dictionary (general) 126, a difficulty determination dictionary (specialized) 127, a display order DB 128, The viewpoint DB 129 is stored.

  As illustrated in FIG. 4, the book DB 121 includes information indicating the title, author, price, issue date, genre, evaluation value (average value of evaluation values by the user), and content introduction text for each book ID. It is registered.

  In the user comment DB 122, information related to comments written by the user on the book is registered. Specifically, as shown in FIG. 5, for each comment ID, the book ID of the book to be commented, the user ID of the user who described the comment, and the user evaluation value for the book to be commented ( 5) and information indicating a comment is registered.

  In the user comment positive / negative DB 123, a positive comment and a negative comment for a book are extracted and registered from comments registered in the user comment DB 122. Specifically, as illustrated in FIG. 6, for each book ID, information indicating a comment and a positive / negative determination result indicating whether the comment is positive or negative is registered.

  The positive / negative determination dictionary 124 is used when a positive comment and a negative comment are extracted from sentences included in a user comment. Specifically, as shown in FIG. 7, a character / character string and a positive / negative value are registered in association with each other. The positive / negative value takes a value of “−1 to 1”, and indicates a negative value as it approaches “−1”, and indicates a positive value as it approaches “1”. Extraction of a positive or negative comment is performed by calculating a total positive / negative value for each comment. For example, if it is a sentence “Easy to read, good book”, it is determined that “easy to do” and “good” are included, and the total value “0.92 + 1.00 = 1.92” is the total positive / negative of this sentence. Value. If the total positive / negative value is equal to or greater than a predetermined threshold value, it is extracted as a positive comment, whereas if it is equal to or smaller than the predetermined threshold value, it is extracted as a negative comment. The extracted comment is registered in the user comment positive / negative DB 123. In the present embodiment, “easy to read” and “easy to read” do not completely match the character strings, but it is determined that “easy to read” is composed of “read” and “easy to read”. It is determined that “easy to read” includes the character string “easy to read”.

  The display order determination dictionary 125 is based on the text included in the user comment or introductory text, before and after the display order of the book that is the target of the user comment or introductory text and the book included in the user comment or introductory text. Used in determining relationships. Specifically, as illustrated in FIG. 8, the phrase and the information indicating the front / rear determination of the processed book are associated and registered. For example, if there is a comment “book B (the title of book B) should be read before this book” as a user comment on book A, book The display order of A is determined later. In addition, as a user comment on the book C, when there is a comment “Book D (title of the book D) is recommended for further understanding of this book”, the display order of the book D over the book C is displayed. Will be decided later.

  The difficulty level determination dictionary (general) 126 and the difficulty level determination dictionary (specialty) 127 are used when calculating the difficulty level of the book based on the user comment on the book, the title of the book, and the introduction text of the book. Specifically, as shown in FIGS. 9 and 10, characters / character strings and difficulty level values are associated and registered. Characters / character strings registered in the difficulty determination dictionary (general) 126 are general words used regardless of the genre of the book. On the other hand, the characters / character strings registered in the difficulty determination dictionary (specialized) 127 are technical terms defined for each genre of books. That is, the difficulty determination dictionary (specialty) 127 is provided for each genre of books, and the difficulty determination dictionary (specialized) 127 shown in FIG. 10 shows an example of a dictionary constructed for books of the IT genre. Yes. In the present embodiment, the difficulty level of the book is indicated by the total difficulty level value. The total difficulty value is difficult to the number of characters / character strings registered in the difficulty determination dictionary (general) 126 and difficulty determination dictionary (specialty) 127 included in the user comment, title, and introductory text. It is a value obtained by multiplying the degree values. For example, when the user comment, title, and introductory text contain 10 “Introduction” and “50” “Unity” (assuming no other characters / character strings are included) The total difficulty value is “1.0 × 10 + 2.0 × 50 = 110”.

  The display order DB 128 shows the display order determined based on the display order determination dictionary 125 and the total difficulty value calculated based on the difficulty determination dictionary (general) 126 and the difficulty determination dictionary (specialty) 127. Information is registered. Specifically, as shown in FIG. 11, information indicating the previous book ID, the subsequent book ID, and the total difficulty level value is registered for each book ID. The previous book ID is the book ID of the book whose display order should be before the book indicated by the book ID, and the subsequent book ID is the display order after the book indicated by the book ID. This is the book ID of the book to be registered, and is registered according to the display order determined based on the display order determination dictionary 125.

  As illustrated in FIG. 12, viewpoint words are registered in the viewpoint DB 129 for each book ID. The viewpoint word is extracted as a word indicating the viewpoint of the book from the user comment on the book, the title of the book, and the introduction text of the book. The viewpoint word can be extracted by a TF (Term Frequency) -IDF (Inverse Document Frequency) method.

  The control unit 11 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The CPU implements various functions by reading and executing various programs stored in the ROM or the storage unit 12.

[4. Positive / negative extraction process by server device 1]
Next, the positive / negative extraction process by the server apparatus 1 is demonstrated using FIG. The positive / negative extraction process is a process of extracting a positive comment 508 and a negative comment 509 displayed on the search result screen 500.

  First, the control unit 11 of the server device 1 acquires, from the user comment DB 122, a user comment that has not been determined as positive / negative (a user comment that has not been subjected to positive / negative extraction processing) (step S1). Although not shown in FIG. 5, a flag indicating whether or not the comment indicated by the comment ID has been subjected to positive / negative extraction processing is registered in the user comment DB 122 for each comment ID. Refers to the flag to determine a user comment for which positive / negative has not been determined.

  Next, the control part 11 divides | segments the user comment acquired by the process of step S1 into a morpheme (step S2). Next, the control unit 11 refers to the positive / negative determination dictionary 124 (FIG. 7), and extracts a positive sentence or a negative sentence (positive negative sentence) based on the characters / character strings divided into morphemes (step S3). Specifically, as described above, the control unit 11 calculates a total positive / negative value, determines whether the sentence is a positive sentence, a negative sentence, or a sentence that is neither, and determines a positive sentence or a negative sentence. Extract.

  Next, the control part 11 registers the positive / negative sentence extracted by the process of step S3 in user comment positive / negative DB123 (FIG. 6) (step S4). Specifically, the control unit 11 associates the book ID of the user comment acquired in the process of step S1, the positive / negative sentence extracted in the process of step S3, and information indicating the positive / negative determination result, and the user comment positive / negative DB 123. Register with.

  Next, the control unit 11 determines whether or not a user comment for which positive / negative is not determined exists in the user comment DB 122 (step S5). At this time, if the control unit 11 determines that there is a positive / non-positive user comment in the user comment DB 122 (step S5: YES), the control unit 11 proceeds to the process of step S1. On the other hand, if the control unit 11 determines that there is no positive-negative user comment in the user comment DB 122 (step S5: NO), the positive-negative extraction process ends.

[5. Viewpoint extraction processing by server device 1]
Next, viewpoint extraction processing by the server device 1 will be described with reference to FIG. The viewpoint extraction process is an extraction process of viewpoints of books registered in the book DB 121.

  First, the control unit 11 of the server device 1 acquires a book ID of a book whose viewpoint has not been extracted from the book DB 121 (step S31). Although not shown in FIG. 4, a flag indicating whether or not the book indicated by the book ID has been subjected to viewpoint extraction processing is registered in the book DB 121 for each book ID. With reference to the flag, a book whose viewpoint has not been extracted is determined.

  Next, the control part 11 acquires a user comment, a title, and an introductory sentence based on the book ID acquired by the process of step S31 (step S32). Specifically, the control unit 11 acquires a user comment from the user comment DB 122 and acquires a title and an introduction sentence from the book DB 121.

  Next, the control unit 11 divides the user comment, title, and introductory sentence acquired in step S32 into words (step S33). Next, the control unit 11 removes unnecessary words (for example, particles and auxiliary verbs) from each divided content (step S34).

  Next, the control unit 11 extracts a viewpoint word representing a viewpoint based on the TF-IDF value of the word from which the unnecessary word is removed in the process of step S34 (step S35).

  Next, the control part 11 registers the viewpoint word extracted by the process of step S35 in viewpoint DB129 (FIG. 12) (step S36). Specifically, the control unit 11 registers the book ID acquired in step S31 and the viewpoint word extracted in step S36 in the viewpoint DB 129 in association with each other.

  Next, the control unit 11 determines whether or not a book whose viewpoint has not been extracted exists in the book DB 121 (step S37). At this time, if the control unit 11 determines that there is a book whose viewpoint has not been extracted (step S37: YES), the control unit 11 proceeds to the process of step S31. On the other hand, when it is determined that there is no viewpoint-unextracted book (step S37: NO), the control unit 11 ends the viewpoint extraction process.

[6. Display order predetermination processing by server device 1]
Next, display order prior determination processing by the server device 1 will be described with reference to FIG. The display order preliminary determination process is a preliminary process for determining the display order when displaying the book information of the books included in the search result on the search result screen 500. That is, the display order determined by the display order determination process described later becomes the final display order after the display order determined in the display order preliminary determination process.

  First, the control unit 11 of the server device 1 acquires a book ID of a book whose display order is not determined from the book DB 121 (step S51). Although not shown in FIG. 4, a flag indicating whether or not the book indicated by the book ID has been subjected to the display order advance determination processing is registered in the book DB 121 for each book ID. 11 refers to the flag to determine a book whose display order has not been determined.

  Next, the control part 11 acquires a user comment, a title, and an introductory text based on the book ID acquired by the process of step S51 (step S52). Specifically, the control unit 11 acquires a user comment from the user comment DB 122 and acquires a title and an introduction sentence from the book DB 121.

  Next, the control unit 11 determines whether or not the user comment and the introductory sentence acquired in the process of step S52 include a part that refers to another book (step S53). Specifically, the control unit 11 determines whether any phrase registered in the display order determination dictionary 125 (FIG. 8) is included in the user comment or the introduction sentence. At this time, when the control unit 11 determines that the user comment and the introduction sentence do not have a reference to another book (step S53: NO), the control unit 11 proceeds to the process of step S55. On the other hand, when the control unit 11 determines that there is a reference part to another book in the user comment and the introduction sentence (step S53: YES), the display order relationship with the other book based on the reference part. Are registered in the display order DB 128 (step S54). Specifically, if the “determination before and after processing book” associated with the matched phrase is “previous”, the control unit 11 includes it in the phrase as “subsequent book ID” in the display order DB 128. The book ID of the book identified by [Title] is registered. On the other hand, if the “determination before and after processing book” associated with the matched phrase is “after”, the control unit 11 is included in the phrase as “previous book ID” in the display order DB 128. The book ID of the book specified by [Title] is registered.

  Next, the control unit 11 divides the user comment, title, and introductory sentence acquired in step S52 into words (step S55). Next, the control unit 11 removes unnecessary words (for example, particles and auxiliary verbs) from each divided content (step S56).

  Next, the control unit 11 refers to the difficulty level determination dictionary (general) 126 and the difficulty level determination dictionary (specialty) 127 for the word from which the unnecessary word is removed in the process of step S56, and sets the difficulty level value and the number of appearances. Based on this, a total difficulty value is calculated (step S57).

  Next, the control unit 11 registers the total difficulty value calculated in the process of step S57 in the display order DB 128 in association with the book ID acquired in the process of step S51 (step S58).

  Next, the control unit 11 determines whether or not a book whose display order is not determined exists in the book DB 121 (step S59). At this time, if the control unit 11 determines that there is a book whose display order has not been determined (step S59: YES), the control unit 11 proceeds to the process of step S51. On the other hand, when it is determined that there is no book whose display order is not determined (step S59: NO), the control unit 11 ends the display order preliminary determination process.

[7. Operation of search system S]
Next, the operation of the search system S will be described with reference to FIG.

  First, the control unit 31 of the client terminal 3 accepts a search condition input by the user (step S101A). Specifically, the user U accesses a book search site that provides a book search service employing the search system S by using a web browser, and inputs a search condition in a search window provided by the book search site. The control unit 31 receives the search condition input in the search window. Next, the control unit 31 transmits search condition information indicating the accepted search condition to the server device 1 (step S102A).

  When receiving the search condition information from the client terminal 3 (step S101B), the control unit 11 of the server device 1 searches for a book based on the search condition indicated by the search condition information (step S102B). Here, although a specific method of book search will not be described, a conventionally known search method can be employed.

  Next, the control unit 11 executes a display order determination process (step S103B) and a difference extraction / emphasis process (step S104B) described later. Next, the control unit 11 generates search result display data for displaying the search result screen 500 based on the processing results of the display order determination process (step S103B) and the difference extraction / emphasis process (step S104B) ( In step S105B, the data is transmitted to the client terminal 3 (step S106B).

  When receiving the search result display data from the server device 1 (step S103A), the control unit 31 of the client terminal 3 displays the search result screen 500 on the display unit 34 based on the search result display data (step S104A).

[8. Display order determination process by server device 1]
Next, display order determination processing by the server device 1 will be described with reference to FIG. The display order determination process is a process for determining the display order when displaying the book information of the books included in the search result on the search result screen 500. Note that the display order determined by the display order determination process, which will be described later, is changed to the final display order.

  First, the control unit 11 of the server device 1 acquires a book search result obtained by the process of step S102B of FIG. 17 (step S201). Next, the control unit 11 refers to the display order DB 128 and provisionally determines the display order of the books included in the search result (step S202). Specifically, the control unit 11 first obtains the total difficulty level value of the book from the display order DB 128 based on the book ID of each book included in the search result, and starts from the lowest total difficulty level value. Set the display order of books in the higher order. Next, the control unit 11 checks whether the display order determined based on the total difficulty value is consistent with the “previous book ID” and the “next book ID” in the display order DB 128. For example, for the book with the book ID “000002” shown in FIG. 11, the total difficulty level value of the book with the book ID “000008” registered as the “subsequent book ID” is “1000.0”. When arranged according to the difficulty level value, the display order is determined so that the book with the book ID “000008” comes before the book with the book ID “000002”, but according to the registered contents of the display order DB 128, the book ID “000008”. The book with “” should be after the book with the book ID “000002”, so the control unit 11 determines that consistency is not achieved. In such a case, the control unit 11 gives priority to the information registered in the “previous book ID” and “subsequent book ID” of the display order DB 128 over the total difficulty level value, and sets the total difficulty level value to the total difficulty level value. The display order determined on the basis is changed. Therefore, in the above case, for example, the control unit 11 inserts the display order of the book with the book ID “000008” immediately after the book with the book ID “000002”.

  Next, the control unit 11 determines whether or not a series of books is included in the books included in the search result (step S203). Examples of series books include a novel composed of an upper volume, a middle volume, and a lower volume, and a pictorial book composed of a plurality of volumes. Whether it is a series product can be determined based on, for example, a title. A book titled “XXX” and a book titled “XXX” can be determined as a series product (when XXX is the same). At this time, as the order in which the books of the series should be read, the control unit 11 should read the book titled “XXXXX” above before the book titled “XXX”. judge. In addition, information indicating whether it is a series product in the book DB 121 and the order to be read in the case of a series product (for example, in the case of a novel first volume, middle volume, and lower volume, an upper volume, a middle volume, and a lower volume) In the process of step S203, it may be determined based on these pieces of information whether the books in the series are included or in which order they should be read.

  When the control unit 11 determines in the process of step S203 that the books included in the search result do not include a series of books (step S203: NO), the control unit 11 temporarily determines the process in step S202. The display order is determined as the main determination (step S206), and the display order determination process is terminated. On the other hand, when the control unit 11 determines that the books included in the search result include a series of books (step S203: YES), the control unit 11 matches the display order provisionally determined in the process of step S202. It is determined whether or not the characteristics are correct (step S204). Specifically, the control unit 11 confirms that the display order of the books in the series is consistent with the order in which they should be read, for example, the display order is such that the first volume is displayed after the second volume of the novel. Check if it has not been decided.

  When the control unit 11 determines in the process of step S204 that the display order temporarily determined in the process of step S202 is consistent (step S204: YES), the display temporarily determined in the process of step S202. The order is determined as the main determination (step S206), and the display order determination process is terminated. On the other hand, if the control unit 11 determines that the display order temporarily determined in the process of step S202 is not consistent with the process of step S204 (step S204: NO), the control unit 11 follows the order in which the series items should be read. The display order is corrected (step S205), the display order is finally determined (step S206), and the display order determination process is terminated.

[9. Difference extraction / emphasis processing by server device 1]
Next, difference extraction / emphasis processing by the server device 1 will be described with reference to FIG.

  Next, the control part 11 acquires the difference between each book from the division | segmentation content from which the unnecessary word was removed, and records it in the memory | storage part 12 for every book (step S234). The difference between each book is a portion (sentence) described in only one book, and is specified by comparing character strings. The difference recorded in the storage unit 12 is displayed as the content 510 written only in the book on the search result screen 500.

  Next, the control part 11 acquires the display order determined by the process of step S206 of FIG. 18 (step S235). Next, the control unit 11 determines a word to be highlighted for each book on the basis of the display order acquired in the process of step S235 for the word from which the unnecessary word has been removed, and records it in the storage unit 12 (step S236). Specifically, the control unit 11 highlights a book with a higher display order (a book with a lower difficulty level) and a general word, and a book with a lower display order (a book with a higher difficulty level). Decide to highlight professional words. Thereby, in specialized books, general words can be highlighted in the introductory book, and specialized words can be highlighted in the application book.
