Description

A question-and-answer system for correcting misinterpretations and deriving intentions {QUERY AND ANSWER SYSTEM}

The present invention relates to a question-and-answer system for correcting misinterpretation and deriving intentions, and more particularly, in order to present an accurate response to a query presented by the inquirer, a sub-category is generated from a sub-category It relates to a question-and-answer system that repeats the steps of analysis, question generation, query and response reception a plurality of times so that it can be derived by asking a reverse question.

In general, an information search method analyzes a query input by a user, and sorts and provides search results corresponding to the analyzed query in order of popularity.

For example, when a user enters 'drum' as a query and wants to search for information related to the drum, which is an instrument, the conventional information retrieval method shows that 'drum washing machine' is popular as a search result corresponding to 'drum' by other users. If it is high, there is a problem in that a user's desired search result cannot be preferentially provided by providing a drum washing machine as a search result preferentially rather than a drum, which is a musical instrument that the user wants to search.

For example, when the query input by the user is 'jeans', the conventional information search method searches only popular products among men's jeans or women's jeans. If it is provided as , it results in the user not being able to properly search for the desired information.

In addition, when a user inputs only jeans, it is impossible to know which information among various information related to jeans, such as meaning, sales place, type, color, etc.

As such a prior art, Korean Patent Registration No. 10-0952284 "Method and System for Providing Search Service Using Timely Query Words" is mentioned.

The question-and-answer system for correcting misinterpretation and deriving intentions according to the present invention is designed to more accurately determine the query intent of the inquirer, and to provide an accurate response through this.

1 and 2, information related to the message input into the database unit is retrieved through the step 10 of receiving the querying message, the step of analyzing the morpheme of the received message (20), and the analyzed message. generating a query by searching (30), outputting the query to the inquirer (40), receiving a response message to the query (50), analyzing the message, generating a query, querying and It is characterized in that it consists of repeating the step of receiving the response message, and deriving and outputting an answer to the questioner's question according to the response to the inquirer (60).

First, the question-and-answer system according to the present invention can be applied to portal sites, mobile devices, messengers, and the like. When a queryer inputs a message, the message is received, and the message is transmitted through the steps of analyzing the morpheme of the received message. made to be recognizable.

The morpheme analysis step analyzes the words or sentences of the received message or both. The ETRI morpheme analysis algorithm refers to the Hangul morpheme analysis algorithm disclosed by the Korea Electronics and Telecommunications Research Institute as an open API. It is also possible to use the API opened by Google for English morpheme analysis.

As described above, when the message is recognized by analyzing the morpheme of the received message, information related to the message is retrieved. At this time, the database unit is accessed to search for related information. At this time, the database unit is stored in a physical hard drive. Data such as encyclopedias and dictionaries, and web pages, homepages, sites, and shopping information connected through networks and the Internet can all be included.

In this case, in the present invention, a classification algorithm for classifying each search information by upper category and lower category may be introduced in order to secure search convenience, and a question corresponding to the searched category, particularly the upper category, is generated.

For example, when a queryer searches for 'automobile', the database unit classifies the search word 'automobile' into subcategories, that is, into categories of imported and domestic cars, and then asks questions such as 'imported cars' and 'domestic cars'. is created, and the generated question is outputted to the queryer to query.

As described above, the inquirer is asked a question, answers it, and if the answer is 'domestic car', the message is analyzed to allow selection by manufacturer, which is a sub-category, again.

As another embodiment, the category may be classified into a tree-type category, and after analyzing a message, a search may be started from a category within a group set as the highest category.

Specifically, when searching for vacuum cleaner filter replacement, search for “cleaner” in the product category. When "cleaner" is searched for, "CB2008" is searched for in the model group category corresponding to "cleaner", and then "filter" is searched for in the parts group category corresponding to "CB2008". Finally, "replacement" is searched for in the action group category corresponding to "filter", and a more accurate result can be derived by asking the queryer a query that induces an answer, such as a model name, in each search process.

As described above, the present invention repeats the steps of analyzing the message, generating a query, and receiving the query and response message, and gradually subcategorizes the questions to generate sub-categories so that the query intention of the inquirer can be clarified. This is done to provide accurate information.

In addition, as these questions are limited to 3 to 5 questions, it is desirable not to accumulate fatigue on the questioner. It's good to be able to react.

These predicted answers and questions are generated by calculating the question and answer probabilities through the conventional accumulated data, and based on the correlation ratio for each category.
