An embodiment of the present invention will be described with reference to the accompanying drawings. When possible, the same parts are designated by the same reference numerals, and duplicate description is omitted.

FIG. 1 is a block diagram showing a functional configuration of the dialogue server 100 and the user terminal 200 of the present embodiment. The dialogue server 100 is a device that searches for response candidates corresponding to the input keywords transmitted from the user terminal 200 and transmits the response candidates to the user terminal 200. For example, it is used in the FAQ search system.

The dialogue server 100 includes a receiving unit 101 (acquisition unit), a search unit 102, a response unit 103, a truth table database 104, and a FAQ database 105. Further, the user terminal 200 includes a key reception unit 201, a user information storage unit 202, a communication unit 203, and a display unit 204. First, each configuration requirement of the dialogue server 100 will be described.

The receiving unit 101 is a part that receives an input sentence transmitted from the user terminal 200 and acquires an input keyword.

The search unit 102 is a part that searches the truth table database 104 based on the input keyword and acquires response candidates. In the present embodiment, the response candidate is, for example, a question sentence candidate for an input keyword in the FAQ search system. Further, the search unit 102 uses the user information transmitted from the user terminal 200 to perform a search for further narrowing down the response candidates. In addition, the search unit 102 may select a search keyword for narrowing down the response candidates instead of the user information based on the frequency of use and the like, and acquire it from the truth table database 104 as a listening back key.

The response unit 103 is a part that transmits the response candidate or the listen-back key searched by the search unit 102 to the user terminal 200.

The truth table database 104 stores one or more search keywords in association with a question sentence candidate which is a response candidate. The truth table database 104 is created by the administrator of the dialogue server 100 based on the question sentence candidates of the FAQ database 105. The dialogue server 100 includes an information processing unit that performs morphological analysis, and the information processing unit automatically extracts search keywords from question sentence candidates by referring to the FAQ database 105, and constructs a truth table database 104. May be. As for the combination of search keywords in the truth table database, it is preferable that different keywords are set for each question sentence candidate so that the question sentence candidate can be uniquely determined.

The FAQ database 105 stores the question text and the answer in association with each other. The question text and the question text candidate are the question text or the candidate thereof desired by the user. For example, it is a sentence such as "how to operate a terminal". In the present embodiment, the question sentence is referred to as a question sentence candidate in the state before the decision, but the content thereof does not change.

The answer is the answer to the question. For example, when the question sentence candidate is related to the operation method, it is information about the operation method. The answer may be shown in text, or it may be a link to an external server that describes the operation method. The truth table database 104 and the FAQ database 105 may be constructed as one database.

Next, the configuration requirements of the user terminal 200 will be described.

The key receiving unit 201 is a part that receives an input sentence by being operated by the user.

The user information storage unit 202 is a part that stores user information of the user terminal 200. The user information is, for example, setting information such as a model name of the user terminal 200, a model identifier, a user's gender / characteristic, a user's address, and a language used by the terminal. The so-called user information is identification information that identifies a user or a user terminal 200, or information that indicates the characteristics, settings, or attributes thereof. This information may be set by the user or may be preset in the terminal.

The communication unit 203 is a part that transmits an input sentence input by the user, an affirmative / negative instruction for listening back, and user information to the dialogue server 100. In addition, it is a part that receives a question sentence candidate or a reply keyword from the dialogue server 100.

The display unit 204 is a part that interactively displays an input sentence, a question sentence candidate, or a reply keyword input by the user. That is, the display unit 204 is a part that displays a dialogue screen with the dialogue server 100.

Next, the operation of the dialogue server 100 and the user terminal 200 configured in this way will be described. FIG. 2 is a sequence diagram showing the operation.

In the user terminal 200, the key reception unit 201 receives input text from the user (S101), the communication unit 203 extracts user information from the user information storage unit 202 (S102), and inputs input text and user information. It is transmitted to the dialogue server 100 (S103).

In the dialogue server 100, the receiving unit 101 receives the input text and the user information transmitted from the user terminal 200. The receiving unit 101 extracts the input keyword from the input text and recognizes the input content (S104).

The search unit 102 performs a search process on the truth table database 104 based on the extracted input keywords, and extracts one or more question sentence candidates (S105). When there are a plurality of extracted question sentence candidates, the search unit 102 compares the user information acquired in step S103 with the search keywords of the extracted plurality of question sentence candidates (S106). The user information to be compared may be one or a plurality. Further, as described later, the combination of a plurality of user information may be changed and compared. Further, as the user information used for the search, it is preferable to give priority to the user information described in the truth table database 104 as the search keyword.

As a result of the comparison, the search unit 102 determines a question sentence candidate associated with the search keyword that matches the user information (S107). In addition, even if the search unit 102 uses the user information, if a plurality of question sentence candidates remain, all of them may be determined as question sentence candidates, and the search unit 102 may match the search keyword in the truth table database 104. One question sentence candidate may be determined based on the degree of (the number of matching keywords).

The response unit 103 transmits the determined question sentence candidate to the user terminal 200. In the user terminal 200, the user instructs the question sentence candidate with the intention of affirmation / denial. In the present embodiment, when the user gives an affirmative instruction, the user terminal 200 transmits to that effect to the dialogue server 100 (S108).

In the dialogue server 100, the search unit 102 acquires the answer corresponding to the question sentence candidate that received the affirmative instruction from the user terminal 200 from the FAQ database 105 (S109). The response unit 103 transmits a question sentence (question sentence candidate) and its answer to the user terminal 200 (S110).

By using the user information transmitted from the user terminal 200 in this way, it is possible to narrow down the question sentence candidates without having unnecessary dialogues, and it is possible to reduce the number of dialogues.

Next, a specific example of the dialogue screen of the user terminal 200 in the above processing will be described. FIG. 3 is a diagram showing a specific example of the dialogue screen in the user terminal 200. As shown in FIG. 3, the balloon u1 indicates an input sentence input by the user by operating the key reception unit 201. The dotted line frame u11 indicates the user information stored in the user information storage unit 202. Here, as the user information, the terminal used: terminal A and the gender: male are stored. Although the dotted line frame u11 is specified for convenience of explanation, it is not displayed on the actual dialogue screen. The balloon s2 indicates a question sentence candidate searched by the dialogue server 100.

In the dialogue server 100, the receiving unit 101 receives the input sentence indicated by the balloon u1 and extracts the "operation method" as an input keyword from the input sentence (corresponding to S104 in FIG. 2). The search unit 102 performs a search based on the "operation method" and acquires a question sentence candidate (corresponding to S105 in FIG. 2).

On the other hand, as shown in FIG. 4, the truth table database 104 stores the question sentence candidates and the search keywords in association with each other. As shown in FIG. 4, the search keywords "terminal A" and "operation method" are associated with the question sentence candidate "operation method of terminal A". Further, the "terminal B" and the "operation method" are associated with the "terminal B operation method". Further, "PC" and "operation method" are associated with "PC operation method". The truth table database 104 naturally stores other question sentence candidates and their search keywords.

Then, the search unit 102 searches the truth table database 104 using the search keyword "operation method" as a key, and searches for the question sentence candidates "operation method of terminal A", "operation method of terminal B", and "PC". "Operation method" is extracted (S105 in FIG. 2).

Further, the search unit 102 narrows down the question sentence candidates by using the user information. Here, the search unit 102 compares the user information with the search keyword of each question sentence candidate (S106 in FIG. 2), and sets the user information: "operation method of terminal A" including the terminal A as the question sentence candidate. Determine (S107 in FIG. 2).

The response unit 103 generates a message including the question sentence candidate extracted by the search unit 102, and performs a transmission process. Specifically, as described in the balloon s2, do you want to display the answer about "How to operate terminal A"? ] Message is generated and sent to the user terminal 200. The user terminal 200 displays the message on the dialogue screen.

In the past, when narrowing down the question sentence candidates, the question sentence candidates were gradually narrowed down by asking the user back using the search keyword, but by using the user information, the questioning back processing is omitted. be able to.

Next, a process when the user denies the question sentence candidate presented by the dialogue server 100 will be described. FIG. 5 is a sequence diagram showing the operation. Steps S101 to S107 are the same as in FIG.

In the dialogue server 100, when the response unit 103 transmits the question sentence candidate and the receiving unit 101 receives the negative instruction from the user terminal 200 (S108a), the search unit 102 is included in the negatively instructed question sentence candidate. Instead of the user information, one search keyword is acquired from the truth table database 104 as a return key (S112). As described above, the selection as the listening key is determined based on the frequency of use in the truth table database 104 and the like.

In the dialogue server 100, the search unit 102 determines a question sentence candidate including one search keyword selected as the listening key (S113). The response unit 103 transmits the question sentence candidate to the user terminal 200. In the user terminal 200, the display unit 204 displays the question sentence candidate, and the key reception unit 201 receives affirmative / negative instructions for the question sentence candidate from the user.

As a result, it is possible to narrow down the question sentence candidates without using the user information. In the above description, the search-back process is performed using the search keyword (list-back keyword), but instead of the listen-back keyword, another user information may be used to narrow down the question sentence candidates.

FIG. 6 is a diagram showing a dialogue screen in the above process. The balloon u3 is an input sentence input by the user. Similar to the above, the dotted line frame u31 is the user information stored in the user terminal 200.

When the dialogue server 100 receives the input sentence and the user information from the user terminal 200, the dialogue server 100 determines "the operation method of the terminal A" as a question sentence candidate using the user information and transmits it. In FIG. 6, does the dialogue server 100 display the answer about "the operation method of the terminal A"? 』Generate and send a message.

In the user terminal 200, the negative operation of the question sentence candidate is performed, and the negative instruction is transmitted to the dialogue server 100. On the dialogue screen, "No" is displayed as indicated by the balloon u32.

In the dialogue server 100, the receiving unit 101 receives the denial of the question sentence candidate "operation method of the terminal A", and the search unit 102 determines that the user information: terminal A has been denied.

Therefore, the search unit 102 excludes the user information: terminal A from the search keyword, extracts another new search keyword from the truth table database 104, and performs a search based on the search keyword. In FIG. 6, the search unit 102 selects "terminal B" as a search keyword, and transmits this as a return keyword to the user terminal 200.

If the question text candidate determined using the user information is denied by the user, it is assumed that the user information is inappropriate. Therefore, in such a case, performing a search without using user information leads to a reduction in the number of dialogues.

In FIG. 6, the acquired key is described as terminal A (user information) and operation method (normal). The acquired key indicates the keyword used in the search, and the parentheses indicate the source of the keyword. By displaying this notation on the dialogue screen, the user can know what kind of keyword is used in the search result, and can accurately understand the search result.

Next, a modified example in the processing of the dialogue server 100 for searching by combining user information will be described. FIG. 7 is a diagram showing a dialogue screen (another example) in the user terminal 200. As shown by the dotted line frame 21, the user terminal 200 stores the constellation: Gemini and blood type 0 as user information. As described above, the dotted line frame 21 is shown for convenience of explanation, but it is not actually displayed.

When the receiving unit 101 receives the input sentence "tell me fortune" and the constellation of user information: Gemini and blood type: O type in the dialogue server 10, the input keyword "fortune" is first acquired from the input sentence. .. The search unit 102 searches for some question sentence candidates using the input keyword "fortune" as a key. Further, the user information is combined with each other to narrow down the question sentence candidates (see step S106 in FIG. 2). For example, the search unit 102 searches with a combination of "Gemini", "O type", and "Gemini, O type". Depending on the combination of user information, the question sentence candidate may not be linked. In that case, of course, it is not possible to narrow down the question sentence candidates.

In the example of FIG. 7, the following question sentence candidates are narrowed down.

-Gemini fortune-O-type fortune-Gemini O-type fortune The user instructs the appropriateness from these question sentence candidates, and the dialogue server 100 gives the user the question sentence and the answer according to the instruction. Can be presented to.

FIG. 8 is a specific example of the truth table database 104 used in the dialogue screen of FIG. 7. As shown in FIG. 7, in the truth table database 104, "Gemini fortune", "O-type fortune", and "Gemini O-type fortune" are stored together with their respective search keywords. The truth table database 104 is used to enable the dialogue shown in FIG.

If the user denies each question sentence candidate obtained from the combination of these user information, the user does not use the user information, but uses other search keywords to perform a repeat process or the like. The search process is performed with.

Next, it may be preferable not to use the user information based on the relationship between the input keyword and the search keyword in the truth table database 104. FIG. 9 is a diagram showing a specific example of the dialogue screen and a specific example of the truth table database 104 in order to explain a suitable example thereof.

FIG. 9A is an example of a dialogue screen. As shown in the figure, the user inputs "Tell me how to operate the terminal B" as an input sentence (speech balloon u4). The user terminal: terminal A is registered as the user information (dotted line frame u41). Referring to FIG. 2, in order to execute a search using user information, the search unit 102 of the dialogue server 100 performs a search using the input keywords "terminal B" and "operation method", and then the user information. A search is performed using "terminal A" (FIGS. 2 S105 and S106).

However, in this example, the truth table database 104 of the dialogue server 100 stores only the search keywords "terminal B" and "operation method" in association with the "operation method of terminal B" (FIG. 9 (b). )).

Therefore, the input keyword and the search keyword are completely matched, and the search unit 102 can determine that there is no need to further perform a search using the user information. Therefore, the search unit 102 can determine one question sentence candidate without performing step S106 in FIG.

In FIG. 9A, the dialogue server 100 further transmits an answer about "the operation method of the terminal B" to the user terminal 200 (speech balloon s4). Therefore, the number of dialogues can be reduced.

Therefore, when the input keyword and the search keyword completely match, it is not necessary to further narrow down using the user information, and the search unit 102 determines the question sentence candidate corresponding to the input keyword. If there are a plurality of question sentence candidates, all of the plurality of question sentence candidates are provided to the user terminal 200 as question sentence candidates.

Next, a process for determining a question sentence candidate by combining input keywords and user information so as to completely match the search keyword in the truth table database 104 will be described.

FIG. 10 is a diagram showing a specific example of the dialogue screen and a specific example of the truth table database 104 when performing the processing.

FIG. 10A shows a specific example of the dialogue screen. As shown in the figure, the user inputs "Tell me how to operate the terminal B" as an input sentence (speech balloon u5). In the user terminal 200, the user terminal: terminal A, gender: male,: Japanese are registered as user information (dotted line frame u51).

On the other hand, FIG. 10B shows the stored contents of the search keyword and the question sentence candidate in the truth table database 104. In order to make an exact match with the search keyword shown in FIG. 10B, the search unit 102 of the dialogue server 100 searches by the "operation method" of the input keyword, and then performs a search using the user information. Select Terminal: Terminal A, Language: Japanese.

As described above, in the dialogue server 100, the search unit 102 can determine more appropriate user information by selecting a combination of the input keyword and the user information that exactly matches the search keyword in the truth table database 104. ..

In the example of FIG. 10A, the dialogue server 100 transmits "the operation method of the terminal A in Japanese" to the user terminal 200 as a question sentence candidate (speech balloon s5).

Next, the operation and effect of the dialogue server 100 of the present embodiment will be described. The dialogue server 100 is a dialogue server that responds to search results based on input by the user, and the receiving unit 101 acquires input keywords from the user terminal 200 operated by the user and is associated with the user. Receive information.

The truth table database 104 stores one or more search keywords in association with a question sentence candidate (corresponding to a response candidate), and the search unit 102 stores input keywords and user information from the truth table database 104. Search for response candidates corresponding to.

The response unit 103 transmits the response candidate searched by the search unit 102 to the user terminal 200.

According to the dialogue server 100, the number of dialogues with the user terminal 200 can be reduced by using the user information. Therefore, it enables an efficient search for the user. Further, for the dialogue server 100, by reducing the number of dialogues, it is possible to reduce the hardware load of the control unit that controls the processing operation. In addition, network traffic can be reduced.

In the above description, the user information is supposed to be transmitted from the user terminal 200, but the user information is not limited thereto. User information such as user attribute information or registration information is registered in the dialogue server 100 or other servers arranged on the network, and the dialogue server 100 may acquire user information from there. In that case, it is necessary to associate the identification information such as the user ID with the user information. Further, the dialogue server 100 needs to acquire a user ID and the like from the user terminal 200 when performing a search.

In the dialogue server 100, the search unit 102 may perform a search for prompting additional input according to the input keyword and the user information. For example, if it is not possible to narrow down the question sentence candidates to a predetermined number or less even by using the input keyword and the user information, the question sentence candidates may be narrowed down by using the listening key to further prompt the additional input. ..

Further, in the dialogue server 100 of the present embodiment, the search unit 102 performs a search based on the input keyword to obtain a plurality of question sentence candidates (response candidates), and among the plurality of question sentence candidates (response candidates). Search for question text candidates (response candidates) that include user information. The response unit 103 transmits the searched question sentence candidate (response candidate) to the user terminal 200.

According to the dialogue server 100, when the same keyword as the user information is registered in the truth table database 104, the search can be efficiently performed by giving priority to the keyword. That is, the user information may include information that is not directly related to the search, such as gender and age. Even if such user information is used, the search efficiency does not increase and it does not contribute to the reduction of the number of dialogues. Therefore, when there is a plurality of user information, the search efficiency can be improved and the number of result dialogues can be reduced by giving priority to the information registered in the search database.

In the dialogue server 100, the search unit 102 performs a search using one or a plurality of user information according to predetermined conditions among the plurality of user information.

As predetermined conditions, keywords included in the closest question sentence candidate (response candidate), keywords included in all question sentence candidates (response candidate), and question sentence candidate (response candidate) at the top of the ranking. By switching the user information according to the question sentence candidate (response candidate) such as the keyword and the keyword of the question sentence candidate (response candidate) based on the match type, it is possible to improve the reduction of the number of dialogues.

When selecting the user information included in "all question sentence candidates", select the user information in which the input keyword and the user information and the search keyword of the truth table database 104 are a perfect match. Is good. The perfect match is a state in which one or more search keywords associated with each question in the truth table database 104, the input keywords, and the user information are matched without excess or deficiency.

When the user information that is a perfect match is selected, the dialogue server 100 can return the question sentence candidate corresponding to the perfect match without returning the listening key.

It should be noted that selecting user information with an excessive number of search keywords, that is, selecting user information with less user information and input keywords than the search keywords (insufficient match) also narrows down the question text candidates. Above, it has technical significance. Therefore, it is conceivable to select user information that is a shortage match in addition to the perfect match.

The "closest question sentence candidate" is a usage in which the number of matches increases when a plurality of search keywords associated with the question sentence candidate are compared with a plurality of keywords consisting of input keywords and user information. It is a question sentence candidate corresponding to the person information. For example, if the search keywords are A, B, and C associated with the question sentence candidate, the input keywords are A, and the user information is B and D, the user information: B is the user information. : The number of matches is larger than that of D. User information in this case: The question sentence candidate using B is the closest question sentence candidate. Therefore, user information: B is selected.

The "question sentence candidate at the top of the ranking" means a question sentence candidate at the top based on the ranking based on the browsing frequency or the like. Ranking based on other criteria may be used regardless of the frequency of browsing.

When the receiving unit 101 receives a negative intention for one question sentence candidate (response candidate) from the user terminal 200 in the dialogue server 100, the search unit 102 does not use the user information used for the search. Search again. For example, the search unit 102 acquires another search keyword from the truth table database 104 instead of the user information, and performs a search using the search keyword.

With this configuration, if the response candidate acquired by the search using the user information is denied by the user, it is considered that the user information is inappropriate for the search. Therefore, in that case, by excluding the user information and re-searching, it is possible to perform an appropriate search and, as a result, improve the reduction in the number of dialogues.

Further, in the dialogue server 100, when there are a plurality of user information, the search unit 102 changes the combination of the plurality of user information and combines the user information with the input keyword to perform each search.

With this configuration, when there are multiple user information, the number of dialogues can be increased by changing the combination of the plurality of user information and performing a search using the changed user information and the input keyword. Can be reduced.

Further, in the dialogue server 100, the search unit 102 uses a keyword group consisting of one or a plurality of search keywords registered for each question sentence candidate (response candidate) in the truth table database 104, an input keyword, and one or a plurality of uses. One or a plurality of user information is selected so that the keyword group consisting of a combination of the person information and the keyword group are completely matched, and the search is performed using the one or more user information and the input keyword.

With this configuration, when there is no question sentence candidate that exactly matches the input keyword and the search keyword, the user information is selected so that the input keyword and the search keyword completely match, thereby enabling an efficient search. That is, the question sentence candidates corresponding to the exact match search keywords without excess or deficiency are likely to be the search results desired by the user, and enable efficient search.

Further, in the dialogue server 100, the search unit 102 completely matches the keyword group consisting of one or a plurality of search keywords registered for each question sentence candidate in the truth table database 104 with the keyword group consisting of the input keywords. If so, do not select one or more user information.

According to this configuration, it is not necessary to select user information when only the input keyword exactly matches the search keyword. Therefore, it enables efficient search.

The block diagram used in the description of the above embodiment shows a block of functional units. These functional blocks (components) are realized by any combination of hardware and / or software. Further, the means for realizing each functional block is not particularly limited. That is, each functional block may be realized by one physically and / or logically coupled device, or directly and / or indirectly by two or more physically and / or logically separated devices. (For example, wired and / or wireless) may be connected and realized by these plurality of devices.

For example, the dialogue server 100, the user terminal 200, and the like in one embodiment of the present invention may function as a computer that performs the processing of the present embodiment. FIG. 11 is a diagram showing an example of the hardware configuration of the dialogue server 100 and the user terminal 200 according to the present embodiment. The above-mentioned dialogue server 100 and user terminal 200 may be physically configured as a computer device including a processor 1001, a memory 1002, a storage 1003, a communication device 1004, an input device 1005, an output device 1006, a bus 1007, and the like. ..

In the following description, the word "device" can be read as a circuit, a device, a unit, or the like.
