The present invention allows the questioner to answer the question through a real-time voice call with an answerer who can answer the question by selecting an answerer from among the experts selected by a predetermined method of selecting an expert to make a phone call with the questioner. The present invention relates to an information providing system and method using a telephone call with an expert to obtain an answer.

1A is a block diagram illustrating a question answer service system 110 according to the prior art. The question and answer service system 110 includes a knowledge sharing system 111 and a knowledge database 112.                         

According to the related art, a user who has a certain question (questioner, knowledge requester) accesses the knowledge sharing system 111 through the Internet using his or her user terminal 110a. Then, by searching the knowledge database 112 by entering a keyword related to his question, it is checked whether a question similar to his question or an answer associated with his question is already registered in the knowledge database 112. If the questioner does not get an appropriate answer to his question through the search, he or she registers his question in the knowledge sharing system 111. In addition, the questioner may register his question directly to the knowledge sharing system 111 without performing the above search.

Another user (answerer, knowledge provider) accesses the knowledge sharing system 111 through the Internet using his user terminal 110b. The answerer searches or browses the questions registered using the knowledge sharing system 111. If the answerer finds a question that he or she can answer, the answerer registers an answer to the question. When the questioner later accesses the knowledge sharing system 111 and searches for his question, the questioner can see the answer to his question.

However, according to this prior art, the questioner has a problem that the answer to his or her question cannot be provided in real time. That is, the questioner has to wait until the answerer is registered with the appropriate answer to his question, the question answering service according to the prior art had a problem that it is difficult to use the questioner who wants to get the answer to the question quickly. Therefore, there is a need for a method capable of providing an 'appropriate answer' in real time to the question of the questioner.

Thus, another prior art provides a system that can answer questions of the questioner in real time. 1B is a block diagram illustrating another real-time counseling service system according to the related art. The real-time consultation service system 120 includes a call server 121, an agent database 122, and an agent database 123. The counselor database 122 stores the telephone number information of the counselor, the specialized field information of the counselor, and the counselor database 123 stores the telephone number information of the counselor.

When the agent 120a requests a phone call with an agent in a specific field of expertise, the call server 121 retrieves the telephone number information of the agent 120b corresponding to the field of expertise from the agent database 122 and receives the call. The telephone number information of the agent 120a is retrieved from the agent database 123 to establish a call between the agent 120a and the agent 120b. When the call is set up as described above, the counselor 120a may be provided with the necessary answer through a telephone call with the counselor 120b.

As such, when using the real-time consultation service system 120 to answer questions through a phone call, the counselor has an advantage in that he / she can consult with a counselor in a predetermined specialty field in real time with a simple phone call.

However, the real-time counseling service system according to the prior art does not provide a specific method for selecting a counselor who is an expert in the specialized field. That is, the prior art selects the counselor as an expert in a certain field based on data such as the age, occupation, company, education, career, qualification, etc. of the counselor, but the data is based on the answering ability of the counselor. The ability to assess how accurate an answer can be to a question).

Therefore, according to the prior art, the counselors who have the same education or experience can only be treated as experts at the same level. However, even if the same counselor has the same educational background or career, the quality of the counseling is different, such as different knowledge levels or different ability to easily understand the same knowledge. By the way, the conventional real-time counseling service provides a reporter to the same level of respondents if the education and career are the same for the respondents providing different levels of answers. Therefore, even if the questioner wants to consult with a high-answer answerer, he or she can not know what level of answering call is connected. There were some irrationalities, such as receiving the same reward as the respondent.

As such, there is a problem that a question and answer service system that allows a user to answer questions and answers through the Internet cannot provide an appropriate answer to a question of a questioner in real time. It is possible, but it does not guarantee whether the answer is a proper answer to the question.

Therefore, there is a demand for a real-time information providing system that can provide a real time answer to a question of a questioner, which can guarantee the level of the answer and further compensate the answerer according to the level of the answer. .

The present invention also provides a computer readable recording medium having recorded thereon a program for executing the above information providing method.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention in detail.

Figure 2a is a diagram showing a network connection of the information providing system according to an embodiment of the present invention, Figure 2b is a block diagram showing the information providing system. As shown in FIG. 2A, the information providing system 200 controls the caller's terminal 201 to be set up with a caller's terminal 202 selected according to a predetermined criterion so that the questioner and the answerer can answer the call. Allows you to answer questions in real time.

The information providing system 200 includes an expert database 210, an answerer selection system 220, a call connection system 230, an evaluation system 240, and a charging system 250.

The expert database 210 maintains, by category, expert information associated with experts selected by category by a predetermined expert selection system. The expert information may include personal information including an expert identifier, a first expert index and a second expert index by category, a total expert index, a ranking of expert indexes by category, link information associated with the expert's question and answer content, a telephone number or a bankbook number. Call information, which is information on whether or not a call is possible, and one or more of reward contents paid to the expert. Detailed description of the expert information will be described later.

The answerer selection system 220 selects an answerer from among experts selected by the expert election system.

The call connection system 230 establishes a call between the terminal of the interrogator who wants a predetermined answer and the terminal of the answering machine so that a telephone call can be made.

The questioner and the answerer may voice a question or answer in real time through the set call. Therefore, unlike a question and answer service that is made on the Internet, a questioner can obtain a real-time answer to his or her question.

The expert election system will be described in detail with reference to FIG. 3. The expert election system 300 includes a first input module 301, a first display module 302, a control module 303, and a first recording module 304.

The first input module 301 receives a question and a category related to the question from a first user through a wired or wireless communication network. The category may be input by providing a first category list to the first user and directly selecting the category. In addition, the first input module 301 maintains a predetermined category and a keyword corresponding to the category, extracts a predetermined keyword from the question using a predetermined analysis method such as a morpheme analysis method, and corresponds to the extracted keyword. By searching for a category, a category selection may be input.

The first display module 302 provides the question on a predetermined web page so that users who have access to the expert election system 300 can view it.

The second user who has received the question on the web page inputs an answer to the question, and the first input module 301 receives the answer from the second user. The first display module 302 also provides the entered answer on the web page.

When the answer is input, the control module 303 increases the number of answers corresponding to the second user and associated with the category. In addition, when the first input module 301 receives a signal for adopting the answer from the first user, the control module 303 increases the number of answer responses corresponding to the second user and associated with the category.

The number of answers associated with a category and the number of adopting answers become data for calculating (or updating) a first expert index corresponding to the second user and associated with the category, as described below.

According to another embodiment of the present invention, the first input module 301 further receives evaluation data on the answer from third users other than the first user and the second user. The control module 303 may use the evaluation data as another data for calculating (or updating) the first expert index.

4 illustrates an example of expert information stored in the expert database 201 in association with the expert election system 300. As shown, the expert database 210 calculates from a user identifier for identifying a second user, a category corresponding to the second user and the number of answers associated with the category, the number of answers adopted, the number of answers and the number of answers adopted. One answer adoption rate, evaluation data, the first expert index, the second expert index, and the overall expert index are stored. In addition, according to an embodiment, the first expert index ranking, the second expert index ranking, or the total expert index ranking may be further stored.

As shown in FIG. 4, the second user 'abc123' answered ten times a question corresponding to the category of 'natural science', and seven answers were selected from the first user who is the questioner. The answer adoption number is a number of answers inputted by the second user as the number of responses adopted by the first user, and is used to calculate the first expert index in that the number of answers having a level enough to be adopted by the first user who is the questioner. Can be used as data. In addition, since the participation degree of the second user can be determined from the number of answers, the number of answers can also be used as a data for calculating the first expert index to select a faithful answerer as an expert.

Also, the answer adoption rate is simply calculated from (number of answers) / (number of answers). Since the quality of the answer may be low even when the second user inputs a plurality of answers and the number of answers is large, it is preferable to reflect the adoption rate of the answer in order to objectively calculate experts in a field corresponding to the category. .

In addition, the third user who sees the question and answer provided by the first display module 302 on the web page inputs the evaluation data, and the evaluation data is also a material for calculating (or updating) the first expert index. Can be used Therefore, since the second user who has provided an answer that gives a good evaluation by the third user is more likely to be selected as an expert, an expert in an area corresponding to the category can be objectively calculated. For example, the input module 301 may be +1 if the answer is helpful to the third user on the web page, or -1 if the answer is inaccurate or inappropriate and is not helpful. It can provide an interface for inputting. In addition, it is preferable that only the third user other than the first user and the second user can input the evaluation data.

The control module 303 calculates the first expert index from each of the data (at this time, it is preferable to calculate the first expert index by weighting it according to the importance of each data). For example, the number of answers 10 x 1 + number of answer adoption (7) x 1 + answer adoption rate (0.7) x 20 + evaluation data (5) x 2 = 41, the first expert index associated with the 'natural sciences' category can be calculated. The control module 303 updates the first expert index whenever there is a change in data such as the number of answers or the number of adopting answers, and the first recording module 304 updates the first expert index by category for the expert database 210. To record.

The control module 303 determines whether the second user 'abc123' is an expert in the 'natural science' field based on the first expert index. For example, the control module 303 selects the second user 'abc123' as an expert in the field of 'natural science' when the first expert index associated with the 'natural science' category is 100 or more. Referring to FIG. 4, the second user 'abc123' is an expert in the field of 'natural science' and an expert in the field of 'computer'.

Meanwhile, the second expert index and the whole expert index stored in the expert database 210 will be described later.

Hereinafter, the answerer selection system 220 will be described in detail with reference to FIG. 5. FIG. 5 is a block diagram illustrating an answerer selection system 520 corresponding to the answerer selection system 220 illustrated in FIG. 2. The answerer selection system 520 includes a second input module 521, a search module 522, a second display module 523, and an answerer selection module 524.

According to an embodiment of the present invention, the second input module 521 receives a selection of a category from the questioner. For example, the interrogator may enter a selection of the category using a predetermined Automatic Response System 529. When the interrogator calls a known representative telephone number through a predetermined web page, a newspaper or a TV advertisement, etc., the interrogator is connected to the answering machine 529. For example, the answering machine 529 may provide the interrogator with a voice prompt message such as "Press 1 for the 'computer' field and 2 for the 'natural sciences' field". When the interrogator presses the first button through a terminal such as his or her own phone, the answering machine 529 transmits a signal corresponding to the first button (an input signal for selecting a 'computer' category) to the second input module 521. To send).

In addition, according to another embodiment of the present invention, the second input module 521 receives a selection of a category from the questioner through a predetermined web page. For example, the answering machine selection system 220 maintains a category and a keyword corresponding to the category in a predetermined category database, and when the interrogator inputs a predetermined keyword, the list of categories corresponding to the input keyword is recalled. The user interface may be provided on a web page and allow the interrogator to select a category from the list of provided categories.

Further, according to another embodiment of the present invention, a list of categories is provided by a directory search method in a predetermined web page of the answerer selection system 220, so that the questioner can input the selection of the category. 6A is a diagram illustrating an example of a list of categories displayed on the web page by a directory search method. FIG. 6A illustrates a case where the 'computer, communication >> hardware' category is selected as a directory search method as indicated by reference numeral 601.

If the interrogator inputs the selection of the 'computer' category according to any one of the various category selection methods as described above, the search module 522 selects the 'computer' selected from the expert database 210 as described above. Retrieve first expert information associated with the category. Accordingly, expert information associated with an expert in the 'computer' field, including the second user 'abc123', is retrieved.

According to an embodiment of the present invention, the answerer selection module 524 selects an answerer based on the first expert index included in the searched expert information. For example, the responder selection module 524 selects an expert whose largest value of the first expert index is the answerer.

For example, as shown in FIG. 7, when three expert information related to the field of 'computer' is found, the answering machine selection module 524 selects the expert 'kome' having the highest first expert index among the callable experts as the answerer. Choose. However, as described below, when the call information is further included in the expert information and the call information is used to select the answerer, the answerer is selected from the experts in the call state based on the call information. That is, the answerer selection module 524 selects the expert 'yukie', which has the highest first expert index, among the 'callable' experts 'naoe' and 'yukie' instead of the expert 'kome' who is in the 'non-call' state. do.

In addition, according to another embodiment of the present invention, the answerer selection module 524 may receive an expert's selection directly from the questioner and select an expert selected from the questioner as the answerer. As indicated by reference numeral 602 of FIG. 6A, the answerer selection system 220 displays the expert identifier associated with each category on the web page. In this case, the expert identifier is preferably displayed in the order of the first expert index. In addition, the expert identifier may be displayed according to the order of all expert indices when selecting an answerer in consideration of the second expert indices to be described later.

If the interrogator selects a specialist by selecting one expert identifier from the list of expert identifiers, the answering machine selection system 220 displays the expert information associated with the selected expert as shown in FIG. 6B. Provide the questioner through the page. For example, the answerer selection system 220 may be associated with a category selected as an expert as indicated by reference numeral 603 (the expert index may be a first expert index, a second expert index to be described later, or described later). Any one of all expert indices may be selected) and expert indices ranking and the like may be provided on the web page.

The questioner selects an expert who is expected to be able to view the expert information displayed on the web page and respond appropriately, and the answerer selection module 524 selects the expert as an answerer when the questioner's selection is entered. do.

As described above, the call connection system 230 controls a call to be established between the terminal of the selected answerer and the terminal of the interrogator. The questioner and the answerer may answer the real-time question by voice through the call set as described above.

After the questioner is provided with the answer, the questionnaire inputs evaluation data about the answerer to the evaluation system 240, and the evaluation system 240 reflects the evaluation data in the expert information.

According to an embodiment of the present invention, the evaluation system 240 maintains the caller's terminal and the call even when the call between the terminal of the interrogator and the terminal of the interrogator is terminated, and provides a predetermined automatic answering system to the interrogator. Send a voice guidance message such as "Please press button 1 if you are satisfied with the answer and button 2 if you are not satisfied with the answer". The evaluation system 240 determines the type of the button input of the questioner in response to the voice guidance message and reflects it on the expert information.

In addition, according to another embodiment of the present invention, the evaluation system 240 may receive evaluation data on the answer of the answerer from the questioner through a predetermined evaluation web page. The questioner who hears the answer through the phone call with the answerer may access a predetermined web page and input evaluation data about the answer into the evaluation system 240.

In addition, according to another embodiment of the present invention, the evaluation system 240 includes a message transmission module, an evaluation data receiving module and a second recording module. The message transmission module controls a predetermined SMS server to transmit a short message including a call back URL or a call back number to the terminal of the interrogator.

The short message includes, for example, a text guide message such as "Please press button 1 if you are satisfied with the answer, press button 2 if you are not satisfied with the answer, and press the call button". The interrogator may view the text guide information and input the evaluation data by pressing the first button (or the second button) and the call button, and the terminal uses the callback URL or the callback number to input the evaluation data. Send to the evaluation data receiving module.

The second control module updates the expert information based on the evaluation data through the evaluation data receiving module.

According to another embodiment of the present invention, the expert information further includes a second expert index. The second expert index is data generated by the evaluation system 240 reflecting the evaluation data. For example, the second control module increases the second expert index by 1 whenever a signal corresponding to the first button (satisfaction) is input, and when a signal corresponding to the second button (dissatisfaction) is input. The second expert index is reduced by one every time.

The second expert index calculated as described above may be used as the data when the answerer selection system 220 selects an answerer from among experts associated with a predetermined category. As shown in FIG. 4, the second expert index is stored in the expert database 210, and the answerer selection system 220 is selected from among experts searched in association with the category in consideration of the first expert index as well as the second expert index. Select a responder. According to another embodiment of the present invention, the answerer selection system 220 weights the first expert index and the second expert index to calculate a total expert index and answer the expert with a high total expert index value as the answerer. Choose.

Referring to the case of FIG. 4 as an example, the total expert index 118 was calculated from {(first expert index) x 1 + (second expert index) x 2}. On the other hand, since the second user 'abc123' was not selected as an expert in the category of 'natural science' category, the second expert index calculated from the evaluation data on the answer of the answer selected by the expert is only 0. none.

In addition, according to another embodiment of the present invention, the expert database 210 further includes call information on whether the expert can talk as described above. The call information may be information on whether a call is possible, such as 'callable' and 'not callable', or may be time information on 'callable period'. The answerer selection module 524 selects only answerable experts as answerers based on the call information included in the expert information retrieved by the search module 522. Therefore, the questioner can obtain a desired answer directly through the phone call with the answerer.

According to the present embodiment, the answering machine selection system 220 receives a callable time from a second user selected as an expert and updates the call information according to the callable time. In addition, when the questioner is to input the selection of the answerer directly from the experts associated with the predetermined category through the expert information provided through the web page, etc., the answerer selection system 220 further provides the call information to the web page or the like. It is desirable to.

In addition, according to another embodiment of the present invention, the answering machine selection system 220 selects an answering person who is determined to be available on the basis of the call information, and thus the call connection system 230 is connected to the answering machine's terminal. If the call setup is attempted but the answerer does not answer and the call setup fails, the evaluation system 240 updates the second expert index associated with the answerer. For example, if the answerer who is determined to be available to answer based on the call information does not answer, the second expert index associated with the answerer is reduced by five. Therefore, the information providing system according to the present embodiment induces the experts selected as the answerers to faithfully participate in the answering activity, while also faithfully updating the call information.

In addition, the evaluation system 240 may increase the second expert index associated with the answerer by 1 when the selected answerer actually establishes the call in response to the call connection request at the available time.

As described below, the second expert index may be used as data for determining the reward content for the answerer in the charging system 250. That is, the content of the questioner's evaluation of the answerer's answer is determined to determine the reward content of the answerer. Therefore, according to the present embodiment, the respondents have an advantage in that they participate in the response activity in an effort to improve the reward contents, such as increasing the amount of compensation.

On the other hand, according to another embodiment of the present invention, the call connection system 230 controls the call setup with the answerer's terminal while already connected to the questioner's terminal. In this case, the expert information includes the phone number information of the expert, and the call connection system 230 controls the call setup between the terminal of the questioner and the terminal of the answerer using the telephone number information.

In addition, according to another embodiment of the present invention, the call connection system 230 establishes a call between the terminal of the questioner and the terminal of the answerer in a call back manner. According to the present embodiment, each step as shown in FIG. 8 is performed in the call connection system 230.

The call connection system 230 receives a question and telephone number information of the interrogator from the interrogator in step 801. According to an embodiment, the call connection system 230 may receive the question by voice from a terminal such as a telephone or a mobile phone of the questioner, or may receive a text through a predetermined user web page. In addition, even when the question is input from a terminal such as a phone or a mobile phone, it is also possible to receive texts using SMS. On the other hand, even when the question is input by voice, the telephone number information is preferably input by text.

The call connection system provides the question to the selected answerer in step 802. The question entered in text may be provided to the answerer in text and the question input in voice. Further, according to another embodiment of the present invention, the question may be provided by voice or text according to the selection of the answerer who is provided with the question (or according to the type of the terminal where the answerer is provided with the question). In this case, a voice recognition system for recognizing a question input by voice and converting it into a text and a text recognition system for recognizing a character to generate a voice should be further provided.

When the answerer who is provided with the question is determined to answer the question, the call connection system 230 requests a call connection with the questioner. When a call connection request is input from the answerer in step 803, the call connection system 230 sets up a call between the interrogator's terminal and the answerer's terminal using the phone number information of the interrogator in step 804. To control.

As such, the call connection system 230 enables the caller to make a phone call with an answerer who has determined that the questioner can answer the question, so that the answerer cannot answer the question only after the call is connected. This prevents the interrogator from repeating the above process to establish a call with a new answerer. If there is no call connection request from the answerer within a certain period, or if a signal is input that is not a call connection request and cannot be answered, the call connection system 230 notifies the answering machine selection system 220 of this fact. Therefore, it is preferable that a new answerer other than the answerer is selected.

According to another embodiment of the present invention, the call connection system 230 selects a new answerer if the answerer cannot answer the question of the questioner even after a call is established between the questioner and the answerer. Make sure you can talk to the questioner.

By such a configuration, the questioner can be provided with a call connection with a new answerer without repeating the above-described procedure such as selecting a category.

At this time, the charging system 250 charges the questioner with the cost associated with the new answerer without charging for the cost associated with the answerer (ie, the cost from the call setup with the answerer to before the call setup with the new answerer). It is desirable to charge only.

In addition, when the signal corresponding to the '*' button is input, the call connection system 230 transmits voice guidance information (or text guide information) on whether the caller's call setting is desired or not to the terminal of the interrogator. It is preferable to control call setup with a new answerer only when a call setup request with a new answerer is input from the questioner.

The billing system 250 determines the costs associated with the questioner in accordance with a predetermined fee calculation method and determines the reward content associated with the answerer in accordance with a predetermined reward calculation method. The cost may be calculated in various ways based on the number of call establishments between the questioner and the answerer, the holding time from the caller to the caller until the call ends, the expert's index, and the like. The reward content may be calculated based on the evaluation data input by the questioner in addition to the call setup frequency, the holding time, and the expert index.
