Abstract

Claims (48)

1 . A method performed by a computing system for providing an integrated chatbot-based service, the method comprising:

receiving, by an integrated chatbot, a query from a user device;

extracting a keyword from the query;

extracting a main keyword by removing, from among the extracted keyword, a keyword that does not match a content keyword previously extracted and stored from content respectively associated with a first chatbot and a second chatbot;

transmitting the extracted main keyword to the first chatbot and the second chatbot;

receiving a content search result corresponding to the extracted main keyword from the first chatbot and the second chatbot; and

providing a response to the query to the user device based on the received content search result.

2 . The method of claim 1 , wherein the content keyword is extracted from content of the first chatbot and the second chatbot based on an occurrence frequency of a keyword.

3 . The method of claim 1 , further comprising:

providing a fall-back message to the user device immediately in response to determining that the main keyword does not exist as a result of the removing of the keyword.

4 . The method of claim 1 , wherein the providing the response comprises:

providing the content search result to the user device when a number of contents included in the content search result is within a predetermined range.

5 . The method of claim 1 , wherein the providing the response comprises:

recommending a search term related to the main keyword when a number of contents included in the content search result exceeds a reference value.

6 . The method of claim 5 , wherein the recommending the search term comprises:

calculating a relevancy score based on a co-occurrence frequency of each content keyword of content keywords appearing in content included in the content search result and the main keyword; and

selecting a content keyword whose relevancy score is equal to or greater than a reference value from among the content keywords; and

configuring a search term recommendation list based on the selected content keyword.

7 . The method of claim 6 , wherein the configuring the search term recommendation list comprises:

configuring the search term recommendation list by arranging the selected content keyword in order of a higher relevancy score.

8 . The method of claim 6 , wherein the relevancy score is calculated based on the co-occurrence frequency and an occurrence frequency of a content keyword.

9 . The method of claim 1 , wherein the providing the response comprises:

recommending, when content does not exist in the content search result and a number of the extracted main keyword is plural, removal of some of the extracted main keywords.

10 . The method of claim 9 , wherein the recommending the removal of some of the extracted main keywords comprises,

providing a removal recommendation list of some keywords by removing one keyword from among the extracted main keywords in order of lower weight and recommending content re-search using remaining main keywords except for the one removed keyword.

11 . The method of claim 10 , wherein the providing the removal recommendation list further comprises:

providing, if content is not searched as a result of the content re-search, a removal recommendation list of some keywords by removing two keywords from among the extracted main keywords in order of lower weight and recommending content re-search using remaining main keywords except for the two removed keywords.

12 . The method of claim 10 , wherein the weight is a value derived using a TF-IDF (Term Frequency-Inverse Document Frequency) algorithm,

wherein the Document corresponds to content.

13 . The method of claim 1 , wherein providing the response comprises,

sorting the content search result according to a predetermined priority to provide it to the user device.

14 . The method of claim 13 , wherein the predetermined priority is based on at least one of a relevancy with a currently ongoing event and a number of views of the searched content.

15 . A system for providing an integrated chatbot-based service comprising:

a memory configured to store one or more instructions; and

one or more processors configured to execute the stored one or more instructions to perform:

receiving a query from a user device;

extracting a keyword from the query;

extracting a main keyword by removing, from among the extracted keyword, a keyword that does not match a content keyword previously extracted and stored from content respectively associated with a first chatbot and a second chatbot;

transmitting the extracted main keyword to the first chatbot and the second chatbot;

receiving, from the first chatbot and the second chatbot, a content search result corresponding to the extracted main keyword; and

providing a response to the user device based on the received content search result.

16 . A non-transitory computer readable recording medium storing computer program executable by at least one processor to perform:

receiving, by an integrated chatbot, a query from a user device;

extracting a keyword from the query;

extracting a main keyword by removing, from among the extracted keyword, a keyword that does not match a content keyword previously extracted and stored from content respectively associated with a first chatbot and a second chatbot;

transmitting the extracted main keyword to the first chatbot and the second chatbot;

receiving, from the first chatbot and the second chatbot, a content search result corresponding to the extracted main keyword; and

providing a response to the query to the user device based on the received content search result.
