METHOD SYSTEM AND COMPUTER PROGRAM FOR KNOWLEDGE EXTENSION BASED ON TRIPLE-SEMANTIC

摘要

According to an embodiment of the present invention, provided are a system, a method and a computer program for knowledge expansion based on Semantic-Triple. The system includes: a data update part updating existing Semantic-Triple data; a query creation module creating a query by using and combining entity synonyms and attribute synonyms; an actual query obtaining part obtaining an actual user query based on a user log; a Semantic-Triple extractor obtaining the query created by the query creation module or the actual user query as an input value, thereby targeting a search target and searching for a passage related with the query by primarily selecting a passage candidate group having relevance in accordance with the characteristic of the query, and deriving an unique instant answer based on the obtained passage and query data; and a Semantic-Triple conversion module converting the query and the unique instant answer, which is a correct answer, into Semantic-Triple which is the format of an entity, an attribute, and an instant answer.
