The flowchart which shows the process sequence in embodiment of this invention. The figure which shows the example of a screen display in embodiment of this invention.

  Next, a mode for carrying out the present invention (referred to as “embodiment”) will be illustrated along the drawings. In addition, the assumptions common to the contents already described in the background art and problems are omitted as appropriate.

[1. Constitution〕
This embodiment relates to a question example presentation device (hereinafter also referred to as “exemplary server 1” or “exemplary server”) that outputs a question example in question answer type content. Then, the example server 1 responds to an access from the terminal T via the communication network N (for example, a mobile communication network such as a mobile phone, a PHS, a public wireless LAN, the Internet, etc.) as shown in the configuration diagram of FIG. Server system. Moreover, the evaluation server 2 is a device that generates the evaluation value data, and a part of the function of the example server 1 is configured as another server, and the function may be provided to the example server 1.

  A question answering type content server 3 that provides question answering type content (hereinafter referred to as “content server 3” or “content server”) provides the question answering type content in response to access through the communication network N. It is a server system. Each of the servers 1 to 3 has at least a part of the configuration of the computer, although not shown in the figure, a communication control unit 6 such as a CPU, a storage device 7 such as a main memory or an auxiliary storage device, and a communication means N 8 (communication circuit with mobile communication network, communication gateway device, wireless LAN adapter, etc.).

  Further, the terminal T (hereinafter also referred to as “terminal”) is a mobile information terminal such as a conventional mobile phone terminal, tablet PC, or other personal computer called a smart phone, a garage (galapago keitai), or another personal computer. Although these terminals are not shown in the figure, in addition to the computer configuration as described above, for example, in the case of a smartphone, an input / output unit using a liquid crystal display panel, a touch panel, a push button, a browser that displays a web page, etc. And having a function. There are actually a large number of terminals T in accordance with the number of users regardless of the schematic FIG.

  In each of the servers 1 to 3, elements (10, 20 and others) such as each unit shown in FIG. 1 are controlled by a predetermined computer program stored (installed) in the storage device 7 controlling the calculation control unit 6. Realize. Among these elements, the information storage means can be realized in any data format such as a file on the storage device 7, or may be remote storage by network computing (cloud). The storage means may include not only a data storage area but also functions such as data input / output and management. In addition, the unit of the storage means shown in this application is for convenience of explanation, and the configuration can be divided or integrated as appropriate, and the processing data and processing results of each means are stored in addition to the explicit storage means. A storage means is used as appropriate.

  Of the storage means, the evaluation storage means 25 of the example server 1 is means for storing evaluation value data relating to the ability to obtain answers to questions, and the evaluation value data is as illustrated in FIG. This is data in which an evaluation value representing the acquisition of an answer to a question in a question-answer-type content by a predetermined standard is associated with a question (represented by a question ID in FIG. 2 (4)) for each category. Further, as illustrated in FIG. 2C, the correspondence data storage unit 15 is a unit that stores correspondence data in which a keyword and a category in the question answer type content are associated in advance. The example of each data shown in FIG. 2 (1) to FIG. 2 (4) shows a correspondence relationship indicated by a broken arrow or the like.

  The arrows in the figure (for example, FIG. 1) supplementarily indicate the main direction of the flow of data, control, etc., and do not deny other flows or imply direction limitations. For example, when data is acquired in a certain direction, a prior data request and a subsequent acknowledge (ACK) are transmitted in the reverse direction. In addition, each means other than the storage means is a processing means for realizing and executing the functions and operations of information processing as described below, but these are functional units arranged for explanation, and actual hardware It doesn't matter if it matches elements or software modules.

[2. Action and effect)
A processing procedure in the present embodiment configured as described above is shown in the flowchart of FIG. Among these, the processing procedure for outputting an example question based on the keyword input by the user is steps S7 to S10 in FIG.

[2-1. (Overview of effects)
That is, when the keyword accepting unit 10 accepts a keyword specification from the terminal T (step S6), the category selecting unit 20 selects the category corresponding to the accepted keyword and the correspondence data stored in the correspondence data storage unit 15 ( The selection is made based on FIG. 2 (3)) (step S7). For example, the category “PC trouble” is selected as the category corresponding to the keyword “error” based on the corresponding data (FIG. 2 (3)).

  Then, the question extraction unit 30 uses the evaluation value data (FIG. 2 (4)) stored in the evaluation storage unit 25 to output a question based on the evaluation value from the questions belonging to the selected category. (Step S8), and the question output means 40 outputs the extracted question (step S9). In the above example, when the questions belonging to the category “PC trouble” are the two question IDs “A123” and “B538” shown in FIG. 2 (4), the higher evaluation value “7.2” is obtained. Question ID “A123” is extracted and output as shown in the screen example of FIG. 4 based on the question answer data (FIG. 2A).

  In this way, from the keyword input by the user (step S6), the corresponding category in the question answer type content is selected (step S7), and the evaluation value representing the ease of obtaining the answer among the past questions in the category is excellent. By displaying a thing as an example (steps S8 and S9), a question suitable for a category corresponding to a keyword can be exemplified. As a result, even a user who is unfamiliar with the question answering type content knows the keyword he / she wants to know, and can input his / her own question with reference to an excellent question example in an appropriate category. For example, in the question example of FIG. 4, it is understood that a question style that specifically describes the PC environment such as the version of the basic software and the software name is preferable in the category of PC trouble.

[2-2. (Calculation of evaluation value)
The evaluation value data used to extract the questions to be output as described above can be avoided by pre-generating unnecessary data if it is generated on the spot after waiting for the keyword to be specified. If it is generated in advance at a predetermined update timing such as (Step S1) (Steps S2 to S5), it is possible to speed up the process of displaying an example of a question after specifying a keyword.

  As an example of generating evaluation value data, for some elements to be reflected in the evaluation value corresponding to the question, first, an element evaluation value that is an evaluation value for each element is obtained, and the evaluation value is calculated based on them. It is conceivable to process in two stages. As a general flow in this case, first, the element evaluation means 21 of the evaluation server 2 refers to the question answer data representing past questions and answers in the question answer type content, and the element evaluation value related to the question and the answer to the question At least one of the element evaluation values for is acquired (step S3). The acquired element evaluation value is stored in the element evaluation value storage unit 22 at least temporarily. Then, the evaluation value calculation unit 23 calculates an evaluation value for the question based on the acquired element evaluation value, and reflects the question and the evaluation value in the evaluation value data (step S5).

  The question answer data refers to, for example, data stored in the question answer storage unit 35 of the content server 3. Although specific element evaluation values will be described later, acquisition of element evaluation values (step S3) and calculation of evaluation values based on the element evaluation values (step S5) are performed at the start of operation of the example server 1 and the evaluation server 2. In addition, the timing is as follows.

  First, with regard to acquisition of the element evaluation value (step S3), the element evaluation value is acquired from the question answer data when the question answer data serving as the basis of the element evaluation value is updated, for example, by increasing a predetermined number or deleted. When a calculation formula, a calculation standard, a parameter, and the like are updated (step S2), re-acquisition, that is, update is performed within the affected range (step S3). In addition, regarding the calculation of the evaluation value based on the element evaluation value (step S5), the evaluation is performed from the element evaluation value even when at least some of the element evaluation values are updated again by acquisition or even if the element evaluation values are not updated. When the calculation formula, calculation standard, parameter, etc. for calculating the value are updated (step S4), the calculation is performed again (step S5).

  In this way, the step of determining the element evaluation value related to the question and the element evaluation value related to the answer (steps S2 and S3) and the step of calculating the evaluation value for each question based on the step (steps S4 and S5) are combined. Therefore, even if the calculation criteria change or basic data update is part of the element evaluation value determination or evaluation value calculation part, it is not necessary to reprocess all other parts, and the processing load Is reduced. If both the element evaluation value related to the question and the element evaluation value related to the answer to the question are acquired and used, a better evaluation value reflecting both the question and the answer can be used.

[2-3. (Criteria for calculating evaluation values)
The specific contents of the element evaluation values to be determined as described above are arbitrary, but as examples of element evaluation values for questions, the number of characters in the question is large or small, the number of questions viewed is large, the spam determination result for the question May be non-spam-like. Further, as examples of element evaluation values related to answers to questions, there are a large number of answers to questions, a short minimum answer time to questions, and the like.

  In addition, methods, criteria, parameters, etc., such as judgment and calculation when obtaining these element evaluation values from question answer data are free, but as a typical example, information obtained from question answer data (for example, the number of questions viewed) , The number of characters in the question, the number of answers to the question) is scored for each range of values, or is scored using a deviation value, logarithm, etc. (eg, a score of 10 out of 10). Even if the dynamic range is large, the expression range of the element evaluation value (the number of quantization bits and its value) can be normalized to a predetermined range that is easy to handle. In addition, about the element evaluation value based on the value that becomes better as the number is smaller, similarly, after scoring to some point out of 10 points, the value obtained by subtracting the score from 10 points out of the full point, or the sign What is necessary is just to make it minus and to reflect in calculation of an evaluation value.

  In addition, the calculation method and criteria for calculating the evaluation value from the element evaluation value are free, but as a typical example, if the evaluation value for the question is calculated by multiplying each element evaluation value by a predetermined weight, for each element evaluation value The balance reflected in the evaluation value can be easily controlled by adjusting the weight. As a simple example, if the average value is calculated with equal weights from the values of the respective element evaluation values corresponding to the question ID “A123” shown in FIG. 2 (2), the evaluation value “4” shown in FIG. 7.2 "is obtained.

  In addition, as mentioned in the above example, by using the element evaluation value related to the small or large number of characters in the question, first, the small number of characters in the question is considered to be a feature of the question that is well expressed. Therefore, a good question that is necessary and sufficient for the category can be exemplified to efficiently use the question answering type content. For example, a simple theme may be thrown to invite various ideas. In addition, since the large number of characters in the question is considered to be a characteristic of the question including sufficient detailed information, an example of an appropriate question including sufficient detailed information in a category in which detailed information represented by PC troubleshooting is important is illustrated. In addition, efficient use of the question-and-answer type content can be achieved.

  In addition, by using element evaluation values related to the number of answers to questions, the number of answers is considered to be a feature of the question that makes people feel like answering even if other people have answered, so that category In this example, questions that make it easy to obtain a large number of diverse answers can be exemplified to promote the use of question answering contents and to enhance answers. For example, it is considered that there is a tendency that the number of answers tends to increase in an example in which questions are asked on a useful new theme after sufficiently checking existing questions and answers.

  Furthermore, by using the element evaluation value regarding the shortest response time to the question, that is, the quickness of the answer, the quickness of the answer is considered to be a characteristic of the question that makes it easy to answer and makes it easy to answer. It is possible to exemplify questions that are easy to obtain answers quickly by category, and to promptly use the question answer type content. For example, a question with the first answer in less than an hour in spite of being late at night is more characteristic to follow than a question with the first answer after a few days. It is done.

  In addition to elements related to answers, as described above, by using the element evaluation value related to the large number of questions viewed, it is considered that the high number of browsing represents the level of interest of people. In this example, questions that are likely to attract attention can be exemplified, and the question answer type content can be effectively used. Even if it is a difficult question, the more people see it, the more likely it is that the person who has the knowledge to answer can see it.

  In addition, as described above, by using the element evaluation value regarding the spam judgment result being non-spam, even if it is automatic judgment, if the judgment result is non-spam, it is often the right question. In addition, since it is considered that there is little risk of being erroneously detected by automatic spam determination, it is possible to exemplify questions that are properly handled in the category and to appropriately use the question answer type content. For example, a question style that is likely to cause spam determination, such as including many links to businesses of genres that are not highly recommended, is considered to be less necessary.

[3. Other embodiments]
In addition, the said embodiment is only an illustration and this invention includes what is illustrated below and other embodiment other than that. For example, the configuration diagrams, data diagrams, flowcharts, and the like in the present application are merely examples, and the presence / absence of each element, the order of the arrangement and processing execution, and the specific contents can be changed as appropriate. As an example, the question example presentation device of the present invention is not limited to a mode realized as a server, but may be realized as an application program (so-called “application”) such as a smartphone, a mobile phone terminal, or a personal computer. In this case, the evaluation value data may be stored locally, but if the data on the remote server is accessed as a remote storage, the local storage capacity is not compressed.

  An example in which the evaluation server 2 is omitted only with the exemplary server 1 shown in FIG. 1 is also within the scope of the present invention. Conversely, the servers 1 to 3 including the content server 3 may be configured integrally. 3 shows the operation of the evaluation server 2 (steps S1 to A5) and the operation of the example server 1 (steps S6 to) in an integrated order for convenience of explanation. Irrelevant or concurrent. In addition, a configuration in which the individual means constituting each of the servers 1, 2, and 3 are further realized by independent devices is also common.

  Further, the evaluation value data (FIG. 2 (4)) does not necessarily exist for all questions belonging to the category, but only questions whose evaluation value is at least a predetermined value (for example, the top number, the top percentage, etc.). You may remember about. As a result, the required data storage capacity can be reduced. In addition, the criteria for extracting the questions to be output are not limited to questions with excellent answer acquisition, that is, in the order of higher evaluation values or higher than a predetermined value, and examples of poor evaluation values may be extracted and output as bad examples. This will help the user avoid bad examples.

  In addition, a predetermined number (for example, three) is extracted in order from the question with the highest evaluation value, and a predetermined number (for example, three, which may be two different numbers) in order from the question with the lowest evaluation value is output. By doing so, it is possible to compare the excellent example and the inferior example, so that it becomes possible to learn the point of the question more effectively.

  In addition, as the expression format of the evaluation value of the question, there is no inevitability that the evaluation value is better as the numerical value is larger, and it may be an expression format that is better as the numerical value is smaller. The numerical value is “predetermined”. Further, when extracting a question or outputting the extracted question, the question text or title does not necessarily need to be included in the evaluation value data, and the question answer storage means 35 of the content server 3 and the like using the question ID as a key. You may acquire from the apparatus of.

  In addition, the configuration of the present invention can be flexibly changed by, for example, realizing each means shown in the above embodiment by calling an external platform or the like with an API (application program interface) or network computing (so-called cloud). it can. Furthermore, each element such as means relating to the present invention may be realized by other information processing mechanisms such as a physical electronic circuit as well as an arithmetic control unit of a computer.
