Description

  The present invention relates to a knowledge search apparatus, a knowledge search method, and a knowledge search program suitable for searching for knowledge (questions and answers) on the Internet, and in particular, can improve the quality of a user interface and answers. The present invention relates to a knowledge search device, a knowledge search method, and a knowledge search program.

  Conventionally, when searching for information published on the Internet, a user accesses a search site provided by a search device using a computer terminal and inputs a keyword. Thereby, the search device displays a search result of information including the search keyword (URL (Uniform Resource Locator) of Web site) on the computer terminal.

  Here, the search result is not necessarily information desired by the user. Therefore, the user must actually open and confirm the Web page corresponding to the URL by a click operation or the like, and it often takes a lot of time to reach a desired search result.

  Therefore, recently, the questioner and the respondent are registered in advance on the search site, the question received from the questioner is published on the search site, and the respondent who viewed the published question searches the answer. A knowledge search device has been proposed in which questions and answers are accumulated as knowledge in a knowledge information database by registering them in, and information desired by the questioner (answers) can be obtained.

Next, the operation of one embodiment will be described with reference to the flowcharts shown in FIGS. 6 to 8 and the various screens shown in FIGS. First, the knowledge search user knowledge search apparatus 10 corresponding to the user terminal 30 _1, the case of registering the query for search miss (if not search hit).

In step SA1 shown in FIG. 6, the control unit 11 of the knowledge search apparatus 10 determines whether or not one of the user terminals 30 ₁ to 30 _n is logged in, and the steps until the login is performed. The determination is repeated with “No” as the determination result of SA1.

Then, based on the user, the user terminal 30 ₁ via the Internet 20, (enter the user ID and password) to log the knowledge search apparatus 10 Then, the control unit 11 sets the determination result in step SA1 "Yes" And At step SA2, the control unit 11 displays the top screen 100 shown in FIG. 9 to the user terminal 30 _1.

  The top screen 100 is a screen for performing knowledge search and question extraction. In the top screen 100, a search keyword input column 101 is a column for inputting a search keyword (for example, a part of a question or a full sentence) for knowledge search. The search button 102 is a button that is pressed when a knowledge search is executed.

  The question status classification column 103 is a column used when questions are extracted based on conditions such as the current status of registered questions and the date and time of question registration. The category list 104 is a specific example of the aforementioned category. The point ranking table 105 is the above-described point acquisition ranking.

  In step SA3, the control unit 11 determines whether or not the search button 102 has been pressed. In this case, the determination result is “No”. In step SA4, the control unit 11 determines whether or not “new” in the question status classification column 103 is checked. In this case, the determination result is “No”.

  In step SA5, the control unit 11 determines whether or not “no answer” in the question status classification column 103 is checked. In this case, the determination result is “No”. In step SA6, the control unit 11 determines whether or not “Resolved” in the question status classification column 103 is checked. In this case, the determination result is “No”. Thereafter, the control unit 11 repeats the determinations of step SA3 to step SA6 until the determination result of any one of steps SA3 to SA6 is “Yes”.

  Then, in order to search for the name of the opening ceremony venue of the Athens Olympics, the user inputs a search keyword “name of the opening ceremony venue of the Athens Olympics” into the search keyword input field 101 and then presses the search button 102.

  Thereby, the control part 11 makes the judgment result of step SA3 "Yes." In step SA7, the control unit 11 performs morphological analysis (the Athens Olympics, opening ceremony venue, name) on the search keyword (“name of the Athens Olympic opening ceremony venue”), and uses a part or all of the search key as a knowledge information database. 15 (see FIG. 3) is searched.

In step SA8, the control unit 11 determines whether a search hit has occurred. In this case, if it is a search mistake (when no search hit occurs), the control unit 11 sets “No” as a result of the determination made at step SA8. In step SA9, the control unit 11 displays the question screen 110 shown in FIG. 10 to the user terminal 30 _1.

  This question screen 110 is a screen for registering a question for obtaining information desired by the user by using a search error as a trigger. In the question screen 110, an urgency input column 111 is a column for inputting the above-described urgency (see FIG. 3) in a selection format. The category selection button 112 is a column for selecting a category to which the question belongs in a selection format.

  The category input column 113 is a column for inputting the category selected by the category selection button 112. The question text input column 114 is a column for inputting the text of the question (for example, what is the name of the venue for the opening ceremony of the Athens Olympics?). In one embodiment, a configuration example may be adopted in which the search keyword input in the search keyword input field 101 (see FIG. 9) is input to the question text input field 114 by default.

  The point input column 115 is a point transferred from the questioner to the respondent who has registered the best answer, and is input by a selection method. The question button 116 is a button that is pressed when a question is registered. In step SA10, the control unit 11 determines whether or not the question button 116 has been pressed. In this case, the determination result is “No” and the determination is repeated.

  Then, the user inputs “ordinary” in the urgency input field 111, “entertainment” in the category input field 113, “what is the name of the Athens Olympic opening ceremony venue” in the question text input field 114, and “10” in the point input field 115. After confirming that “” has been input, the question button 116 is pressed.

  Thereby, the control part 11 makes the judgment result of step SA10 "Yes". In step SA11, after assigning the knowledge ID and question ID, the control unit 11 registers information related to the question in the knowledge information database 15 as shown in FIG. At this time, since no answer is obtained, information such as answer ID 1, answerer ID 1,... Is not registered in the knowledge information database 15.

Moreover, the control part 11 stores question ID of this question in the column of the “posting question ID” of the user in the question history database 16 shown in FIG. In this case, the user who has registered the question (corresponding to the user terminal 30 _1), and added point a predetermined point associated with the question registration, update the point in the user information database 14 shown in FIG.

In step SA12, the control unit 11 determines whether or not the user terminal 30 ₁ corresponding to the user has logged out. In this case, the determination result is “No”, and the top screen 100 is displayed in step SA2 in the user terminal 30 _1. To display. This completes the registration of the question. Information on this question is disclosed through a search result screen 120 (see FIG. 11) and a new question list screen 140 (see FIG. 13), which will be described later.

Next, another user (e.g., corresponding to the user terminal 30 ₂₎ is described for the case of answer to the question. In this case, based on the operation of the user, via the user terminal 30 ₂ is the Internet 20, when logging into the knowledge search apparatus 10, the control unit 11 sets the determination result of step SA1 is "Yes". At step SA2, the control unit 11 displays the top screen 100 shown in FIG. 9 to the user terminal 30 _2.

  Then, the user inputs a search keyword “Athens Olympic” in the search keyword input field 101 in order to answer questions related to the Athens Olympics, and then presses the search button 102.

  Thereby, the control part 11 makes the judgment result of step SA3 "Yes." In step SA7, the control unit 11 performs a morphological analysis (Athens Olympic) on the search keyword (“Athens Olympic”), and searches the knowledge information database 15 (see FIG. 3) using this as a search key.

  In step SA8, the control unit 11 determines whether a search hit has occurred. In this case, if it is a search hit, the control unit 11 sets “Yes” as a result of the determination made at step SA8. In step SA13, the control unit 11 executes a browsing process.

Specifically, at step SB1 shown in FIG. 7, the control unit 11 displays the search result screen 120 shown in FIG. 11 to the user terminal 30 _2. The search result screen 120 is a screen for browsing the search results. Here, the search results are displayed in three columns: an answer acceptance question column 121, an answer deadline question column 122, and a knowledge column 123.

  The answer acceptance question column 121 is a column for displaying a question for which registration of an answer is accepted (for example, answer acceptance question 121a). The answer deadline question column 122 is a column for displaying a question (for example, the answer deadline question 122a) for which a predetermined period has elapsed after the question is registered and the registration of the answer is closed. The knowledge column 123 is a column for displaying a question (for example, knowledge 123a) in which the best answer is selected and knowledge is selected.

  At this time, it is assumed that the answer acceptance question 121a is displayed in the answer acceptance question column 121, and that no information is displayed in the answer deadline question column 122 and the knowledge column 123. This answer acceptance question 121a corresponds to the question registered on the question screen 110 (see FIG. 10).

  The search result screen 120 displays a search keyword input field 124, a search button 125, and a point ranking table 126 as in the top screen 100 (see FIG. 9).

  In step SB2, the control unit 11 determines whether or not the answer acceptance question in the answer acceptance question column 121 illustrated in FIG. 11 has been pressed. In this case, the determination result is “No”. In step SB3, the control unit 11 determines whether or not the answer deadline question in the answer deadline question column 122 has been pressed. In this case, the determination result is “No”.

  In step SB4, the control unit 11 determines whether or not the knowledge in the knowledge column 123 has been pressed. In this case, the determination result is “No”. Thereafter, the control unit 11 repeats the determination of Step SB2 to Step SB4 until the determination result of any one of Step SB2 to Step SB4 becomes “Yes”.

Then, in order to answer the user (corresponding to the user terminal 30 _2), and presses the answer reception question 121a, the control unit 11 sets the determination result in step SB2 as "Yes". In step SB5, the control unit 11 determines whether or not the user is the questioner himself using the user ID (taro) of the user as a key. In this case, the determination result is “No”. In step SB6, the control unit 11 displays the answer screen 130 shown in FIG. 12 to the user terminal 30 _2.

  The answer screen 130 is a screen for registering an answer to the question. In this answer screen 130, the question text display field 131 is the question text entered in the question text input field 114 (see FIG. 10) and registered in the knowledge information database 15 (What is the name of the opening ceremony venue of the Athens Olympics?) Is a column for displaying.

  The answer text input field 132 is a field for inputting an answer to the question displayed in the question text display field 131. The URL input field 133 is a field for inputting a URL. This URL represents the location of the Web site indicating the source of the answer. The book ID input field 134 is a field for inputting a book ID. This book ID is an identifier for identifying a book indicating the source of the answer.

  The answer button 135 is a button that is pressed when the answer input in the answer text input field 132 is registered in the knowledge information database 15. In addition, on the answer screen 130, a search keyword input field 136 and a search button 137 are displayed as in the top screen 100 (see FIG. 9).

In step SB7, the control unit 11 determines whether or not the answer button 135 is pressed. In this case, the determination result is “No” and the determination is repeated. Then, the user (corresponding to the user terminal 30 _2), and respond to answer text entry field 132 (e.g., Athens Stadium) after is entered, the answer button 135 is pressed, the control unit 11, the determination in step SB7 The result is “Yes”.

  When a URL or a book ID is entered in the URL input field 133 or the book ID input field 134, these pieces of information are registered and published together with the answer text as information representing the source of the answer.

  In step SB8, the control unit 11 assigns the answer ID1, and then, based on the input content of the answer screen 130, as shown in FIG. 3, information on the first answer (answer ID1, answerer ID1, answer Text 1 and answer registration date and time 1) are registered in the knowledge information database 15, and the answer ID 1 is stored in the "posted answer ID" column of the user in the answer history database 17.

In this case, the user who has registered the answer (corresponding to the user terminal 30 _2), and added point a predetermined point associated with the reply registration, update the point in the user information database 14 shown in FIG. After completion of these processes, the determination at step SA12 shown in FIG. 6 is performed.

  The answer screen 130 can be called without inputting a search keyword on the top screen 100 (see FIG. 9). Hereinafter, the process in that case will be described.

After other users (corresponding to the user terminal 30 ₂₎ logs in to the knowledge search apparatus 10, the user, in order to view the question newly registered within a predetermined time, the inquiry of the top screen 100 shown in FIG. 9 Check “New” in the status classification column 103. Thus, the control unit 11 sets the determination result of step SA4 as "Yes", in step SC1 shown in FIG 8, to display a new question list screen 140 shown in FIG 13 to the user terminal 30 _2.

  The new question list screen 140 is a screen for browsing a newly registered question. Here, in the question display column 141, all unsolved questions registered within a predetermined time are displayed in a predetermined number in order from the latest registered. In this question display column 141, for each searched question, the registration date of the question, the questioner, the question content, the process, the number of answers, the remaining time, and the category are displayed.

  Further, in the processing column 141a in the question display column 141, an optimum process executed by the user browsing the new question list screen 140 is displayed for each question. By pressing the character, it is possible to shift to the optimum processing.

  Specifically, for a question viewed by a user other than the user who registered the question, the control unit 11 displays “answer question” in the processing column 141a, and when this column is pressed, FIG. The indicated answer screen 130 is called.

  In addition, the display content of a question viewed by the user who registered the question changes depending on whether or not an answer to the question is registered. That is, when the answer is a question that has already been registered, the control unit 11 displays “select the best answer” in the processing column 141a, and when this column is pressed, calls the selection screen 150 (see FIG. 14). . If the answer to the question is not yet registered, the control unit 11 displays “cancel question” in the processing column 141a. When this column is pressed, the question cancellation confirmation screen 170 (FIG. 16) is displayed. Browse). Processing on the selection screen 150 and the question cancellation confirmation screen 170 will be described later.

  As described above, the control unit 11 determines, for each question displayed on the new question list screen 140, the optimum process to be executed by the user who browses, and displays the processing contents in the question processing column 141a. When the process column 141a is pressed, the process is executed. Therefore, the user viewing the question can directly select and execute a process suitable for the question.

  Here, the control unit 11 responds to the question registered by the user whose user ID is “taro” in the processing column 141a as “optimizing a question” as the optimum process for the user browsing the new question list screen 140. "Is displayed.

  The new question list screen 140 displays a search keyword input field 142, a search button 143, a question status classification field 144, and a category list 145, as in the top screen 100 (see FIG. 9).

  In step SC2, the control unit 11 determines whether “answer a question” in the processing column 141a shown in FIG. 13 has been pressed. In this case, the determination result is “No”. In step SC3, the control unit 11 determines whether “select the best answer” in the processing column 141a has been pressed, and in this case, the determination result is “No”.

  In step SC4, the control unit 11 determines whether or not “cancel question” in the processing column 141a has been pressed. In this case, the determination result is “No”. Thereafter, the control unit 11 repeats the determinations of step SC2 to step SC4 until the determination result of any one of steps SC2 to SC4 is “Yes”.

When the user (corresponding to the user terminal 30 ₂₎ presses the "answer questions" of the processing column 141a, step control unit 11 sets the determination result in step SC2 is "Yes", shown in FIG. 7 SB6 The answer screen 130 (see FIG. 12) is called. Thereafter, the control unit 11 executes the processing after step SB7 and registers the answer.

  If “select the best answer” in the processing column 141a is pressed, the control unit 11 sets “Yes” as the determination result in step SC3, and selects the screen 150 (see FIG. 14) in step SB9 shown in FIG. ). When “Cancel question” in the processing column 141a is pressed, the control unit 11 sets “Yes” as the determination result in Step SC4, and calls the question cancellation confirmation screen 170 (see FIG. 16) in Step SC5.

Next, processing after the answer is registered will be described. When the questioner (user terminal 30 ₁ ) logs in to the knowledge search device 10 and performs the above-described operation before the answer is registered and the acceptance of the answer is closed, the control unit 11 displays the “Opening Ceremony for the Athens Olympics” the venue of the name to display the search result screen 120 corresponding to the question? "(see Figure 11) to the user terminal 30 _1.

  At this time, it is assumed that three answers are registered in the answer acceptance question 121a in the answer acceptance question column 121, and the display of the number of answers to the question is changed to “3”. In addition, it is assumed that no information is displayed in the answer deadline question column 122 and the knowledge column 123.

And the control part 11 repeats judgment of step SB2-step SB4. Then, the user (corresponding to the user terminal 30 _1), in order to select one the best answers to the three answers, presses the answer reception question 121a. Thereby, the control part 11 sets the determination result of step SB2 to "Yes", and sets the determination result to "Yes" in step SB5.

At step SB9, the control unit 11 displays the selection screen 150 shown in FIG. 14 to the user terminal 30 _1. This selection screen 150 is a screen for selecting the best answer from the registered answers.

  The selection screen 150 is displayed in the processing column 141a of the new question list screen 140 shown in FIG. 13 in step SC3 shown in FIG. 8 in addition to the case where it is called from the search result screen 120 shown in FIG. It is also called when “Select the best answer” is pressed.

  In this selection screen 150, the question text display field 151 is entered in the question text input field 114 (see FIG. 10) and registered in the knowledge information database 15 (what is the name of the opening ceremony venue of the Athens Olympics?) Is a column for displaying.

Answer text display column 152 _1, the first answer to the displayed question question text display column 151 (e.g., Athens Stadium) is a column for displaying. Selection button 153 ₁ is a button that is pressed to select the first answer as the best answer.

Answer text display column 152 _2, the second answer to the displayed question question text display column 151 (e.g., Athens museum) is a column for displaying. The selection button 153 ₂ is a button that is pressed when the second answer is selected as the best answer.

  In addition, a search keyword input field 154 and a search button 155 are displayed on the selection screen 150 as in the top screen 100 (see FIG. 9).

In step SB 10, the control unit 11 determines whether the selection button (selection button 153 _1, 153 _2, etc.) is pressed, in this case, the result of determination as "No", and repeats the same determination. Then, the user (corresponding to the user terminal 30 _1), and respond Text display column 152 ₁ 1 th answer displayed on is selected as the best answer, when the selection button 153 ₁ is pressed, the control unit 11, step The determination result of SB10 is “Yes”.

  In step SB8, the control unit 11 registers “1” in the selection / recommendation flag 1 (see FIG. 3) corresponding to the selected first answer, and the best answer of this question is selected at the question resolution date and time. Register the date and time. Further, the control unit 11 moves the questioner's point to the user's point corresponding to the best answer on the knowledge information database 15. Thereby, the answer is closed and the first answer and the question are regarded as knowledge, and this knowledge is displayed as knowledge 123a on the search result screen 120 (see FIG. 11).

  Furthermore, the control unit 11 moves the question ID of the question from “published question ID” of the question history database 16 to “solved question ID”. Further, the control unit 11 moves the answer ID of the best answer in the answer history database 17 from “published answer ID” to “best answer ID”, and assigns answer IDs other than the best answer to “published answer ID”. To “Other resolved answer IDs”.

  Here, the configuration is such that the selection screen 150 can be called when the answerer presses the answer acceptance question 121a, but when the number of answers to the question is 0, the questioner may not be able to call the selection screen 150. .

Next, a process after a predetermined period has elapsed after the question is registered and the answer is closed will be described. After the user (user terminal 30 ₁ ) logs in to the knowledge search device 10 and performs the above-described operation, the control unit 11 searches the search result screen 120 corresponding to the question “What is the name of the opening ceremony venue of the Athens Olympics?” (see FIG. 11) is displayed on the user terminal 30 _1.

  At this time, it is assumed that an answer deadline question 122a is displayed in the answer deadline question column 122, and three answers are registered for this question. Also, it is assumed that no information is displayed in the answer acceptance question column 121 and the knowledge column 123.

And the control part 11 repeats judgment of step SB2-step SB4. Then, the user (corresponding to the user terminal 30 _1), in order to select the best answer from three answers, presses the answer deadline question 122a.

  Thereby, the control part 11 makes the judgment result of step SB3 "Yes." In step SB11, as in step SB5, the control unit 11 determines whether or not the user is the questioner himself. In this case, the determination result is “Yes”. In step SB9 and subsequent steps, the control unit 11 calls the selection screen 150 shown in FIG. 14 and executes the above-described process of selecting the best answer.

Further, with respect to responses were closed for questions, a user other than the questioner (e.g., corresponding to the user terminal 30 ₃₎ is able to recommend the best answers to answer. That is, when a user other than the questioner (user terminal 30 ₃ ) logs in to the knowledge search device 10 and then presses the answer deadline question 122 a displayed on the user terminal 30 ₃ through the above-described operation, the control unit 11 The determination result of step SB3 is “Yes”, and the determination result of step SB11 is “No”.

In step SB12, the control unit 11 displays the answer recommendation screen 160 shown in FIG. 15 to the user terminal 30 _3. This answer recommendation screen 160 is a screen for a user other than the questioner to recommend the best answer among the three answers.

  In the answer recommendation screen 160, the question text display field 161 is input to the question text input field 114 (see FIG. 10) and registered in the knowledge information database 15 (what is the name of the opening ceremony venue of the Athens Olympics? ) Is a column for displaying.

Answer text display column 162 _1, the first answer to the displayed question question text display column 161 (e.g., Athens Stadium) is a column for displaying. Recommendation button 163 ₁ is a button which the user touches for recommending the first answer as the best answer.

The answer text display field 162 ₂ is a field for displaying a second answer (for example, Athens Museum) to the question displayed in the question text display field 161. The recommendation button 163 ₂ is a button that is pressed when the second answer is selected as the best answer.

  The answer recommendation screen 160 displays a search keyword input field 164 and a search button 165 as in the top screen 100 (see FIG. 9).

In step SB13, the control unit 11 determines whether or not a recommendation button (recommendation buttons 163 ₁ , 163 ₂ or the like) has been pressed. In this case, the determination result is “No” and the determination is repeated. When the user (corresponding to the user terminal 30 ₃ ) recommends the _first answer displayed in the answer text display field 162 ₁ as the best answer and presses the recommendation button 163 ₁ , the control unit 11 The determination result of SB13 is “Yes”.

  In step SB8, the control unit 11 registers “2” in the selection / recommendation flag 1 (see FIG. 3) corresponding to the recommended first answer and corresponds to the best answer on the knowledge information database 15. Move the questioner's point to the user's point. Thereby, the first answer and the question are used as knowledge.

  Here, the target users who can recommend answers are all users other than the questioner. However, if the answerer who registered the answer to the question views the answer recommendation screen 160, the answer For the answer registered by the person, the recommendation button may be hidden.

  Moreover, when the answer to the registered question is not registered at all, there is a possibility that the answer is difficult because the question content is too specialized, or the question content is contrary to public order and morals. Next, processing in the case where the questioner cancels the question in such a case will be described.

The user who has registered the question (corresponding to the user terminal 30 _1), "cancel the question" is displayed in the processing section 141a of the new question list screen 140 shown in FIG. 13 when is pressed, the control unit 11, FIG. the result of determination in step SC4 shown in 8 and "Yes", in step SC5, and displays the question cancel confirmation screen 170 shown in FIG. 16 to the user terminal 30 _1. This question cancellation confirmation screen 170 is a screen for confirming cancellation of this question to the user.

  In the question cancellation confirmation screen 170, the question text display field 171 is entered in the question text input field 114 (see FIG. 10) and registered in the knowledge information database 15 (the name of the venue for the opening ceremony of the Athens Olympics). ?) Is a column for displaying. A cancellation confirmation message is displayed below the question text display field 171.

  A cancel button 172 and a return button 173 are displayed below the cancel confirmation message. When the cancel button 172 is pressed, the control unit 11 sets the determination result in step SC6 to “Yes”, and executes a process of canceling this question in step SC7.

That is, in step SC7, the control unit 11 deletes all data relating to this question from the knowledge information database 15, and moves the question ID of this question in the question history database 16 from “published question ID” to “cancellation question ID”. . The control unit 11 displays the question cancellation completion screen 180 shown in FIG. 17 to the user terminal 30 _1.

  On the question cancellation completion screen 180, a message indicating completion of question cancellation is displayed, and an option 181 for selecting the reason for canceling the question and a determination button 182 for determining the reason for cancellation are displayed below the message.

When the user selects a cancellation reason from the options 181 and presses the decision button 182, the control unit 11 stores the selected cancellation reason in the knowledge information database 15 and displays the cancellation reason list shown in FIG. 18. It displays a screen 190 to the user terminal 30 _1. Further, by pressing the result display button 183, the cancellation reason list screen 190 can be browsed without selecting the cancellation reason.

  The cancellation reason list screen 190 is always open to all users, and can be viewed at any time, not only when canceling a question. After the process in step SC7 ends, the determination in step SA12 shown in FIG. 6 is performed.

On the other hand, when the return button 173 is pressed on the question cancellation confirmation screen 170 shown in FIG. 16, the control unit 11 returns the determination result of step SC6 to “No”, returns to step SC1, and shown in FIG. to display a new question list screen 140 to the user terminal 30 _1.

  In step SC7, instead of immediately deleting all data relating to the canceled question from the knowledge information database 15, a question cancellation flag is stored in the knowledge information database 15, and the control unit 11 periodically refers to the question cancellation flag. It is good also as deleting all the data regarding the said question.

  In this way, the reason for canceling a question is aggregated, and the function to constantly disclose the aggregation results is provided, so the reason for canceling a question and the number of cases can be clearly indicated to the user, The user can learn what the questionable question is, and can prompt the user to voluntarily improve the quality of the knowledge search system.

  When “no answer” is checked in the question status classification column 103 on the top screen 100 (see FIG. 9), the control unit 11 sets “Yes” as a result of the determination made in step SA5 shown in FIG. In step SA14, an unanswered question display process is executed. That is, in step SA14, the control unit 11 causes the user terminal to display a list of unanswered question list screens (not shown) of questions whose answer count is 0 within a predetermined period of time. For the question selected on the unanswered question list screen, the control unit 11 executes the above-described process of registering the answer or the process of canceling the question. After completion of these processes, the determination at step SA12 is performed.

  Further, in the knowledge search system in this embodiment, when selecting the best answer, user information such as an answer history of the user who registered the answer is displayed as a judgment material for judging the reliability of the answer. Next, a process for displaying user information will be described.

When the questioner (for example, corresponding to the user terminal 30 ₁ ) selects the best answer, the user IDs of the respondents (“jiro”, “j”) in the answer text display fields 152 ₁ and 152 _{2 on} the selection screen 150 (see FIG. 14). When saburo ", etc.) is depressed, the control unit 11 displays the user information screen 200 of the respondents shown in FIG. 19 to the user terminal 30 _1.

  This user information screen 200 is a screen that displays the accumulated points of the user and the breakdown of the question status and answer status so far. By viewing this user information screen 200, the questioner can grasp the answer history of the answerer, and therefore, when selecting the best answer from the answers, it is used as an index for measuring the reliability of the answer. be able to.

  Further, the user information screen of the questioner himself / herself can be called by pressing “view user information” 156 displayed on the selection screen 150 (see FIG. 14). As a result, the questioner can check his / her own question history and answer history.

  In the user information screen 200 shown in FIG. 19, a user result display column 201 is a column for displaying a user ID and points acquired by the user. In addition, in the user result display column 201, a level calculated based on points and the order of cumulative points for all users are displayed.

  Here, when calculating the level, the points acquired, the number of registered questions, the ratio of resolved questions to all registered questions, the number of registered answers, and the ratio of the best answer to all registered answers Used, when all of these values are equal to or greater than a predetermined value, the level of the user is increased.

  The question status breakdown column 202 is a column for displaying a breakdown of the question status registered by the user so far. On the left side of the question status breakdown column 202, the number of questions and points of the registered questions are displayed in association with the question status.

  In the question number column on the left side of the question status breakdown column 202, the number of question IDs of the user stored in the question history database 16 is displayed. “Resolved” indicates the number of resolved question IDs, “Publishing” indicates the number of posted question IDs, “Cancel” indicates the number of canceled question IDs, and “Delete” indicates the number of deleted question IDs. Each number is displayed. In “Total”, the total number of these question IDs is displayed. The points given to the user are displayed separately for each question situation.

  Also, on the right side of the question status breakdown column 202, the question resolution rate and the question deletion rate are displayed as a percentage and a bar graph. The question resolution rate is the ratio of the resolved question ID to the total number of question IDs. The question deletion rate is the ratio of the deleted question ID to the total number of question IDs.

  The response status breakdown column 203 is a column for displaying a breakdown of the response status registered by the user so far. On the left side of the answer status breakdown column 203, the number of answers and points of the registered answers are displayed in association with the answer status.

  In the answer number column on the left side of the answer status breakdown field 203, the number of answer IDs of the user stored in the answer history database 17 is displayed. “Best answer” has the number of best answer IDs, “Published” has the number of posted answer IDs, “Other resolved” has the number of other resolved IDs, and “Deleted” has been deleted The number of answer IDs is displayed. In “Total”, the total number of these answer IDs is displayed. In the point column, the points given to the user are displayed separately for each answer status.

  Also, on the right side of the answer status breakdown column 203, the answer solution rate and the answer deletion rate are displayed as a percentage and a bar graph. The best response rate is the ratio of the best response rate ID to the total number of response IDs. The response deletion rate is the ratio of the deleted response ID to the total number of response IDs.

  The address registration button 204 is a button for registering an address of the user such as e-mail and instant messenger. This address registration button 204 is displayed when a user other than the user browses the user information screen 200.

  Further, on the user information screen 200, a search keyword input field 205 and a search button 206 are displayed as in the top screen 100 (see FIG. 9).

  Thus, by illustrating the question resolution rate in a graph, it is possible to improve the quality of the question content and the best answer selection rate. Further, by graphing the best answer rate, it is possible to easily determine the reliability of the respondent when selecting the best answer. Thereby, the quality of question contents and answer contents can be improved.

  Also, by displaying the question deletion rate and the answer deletion rate in a graph, the past deletion history can be easily grasped by other users, so that inappropriate questions and answers can be suppressed.

  Further, by using the address registration button 204, it is possible to communicate between users, for example, by sending a thank-you message to respondents who frequently register the best answer.

  If the knowledge 123a is pressed on the search result screen 120 shown in FIG. 11 after the best answer is selected for the question and the question has been solved, the control unit 11 shows the result shown in FIG. The determination result of step SB4 is “Yes”. Thereby, in step SB14, the control part 11 displays the knowledge (question and best answer) corresponding to the knowledge 123a on a user terminal as the knowledge screen 210 shown in FIG.

  In this knowledge screen 210, the question text display field 211 displays the text of the question that is regarded as knowledge, and the best answer display field 212 displays the text of the best answer that is regarded as knowledge. The yes button 213 and the no button 214 are buttons for inputting an evaluation as to whether or not this knowledge has been useful to the user. The ratio of pressing the Yes button 213 to the total number of evaluations here is the recommendation rate, and the ratio is displayed in the question display field 221 of the solved question list screen 220 (see FIG. 21) described later.
