First Claim
1. A question answering system for structured knowledgebase using deep natural language question analysis, the question answering system comprising:
- a deep natural language question analysis unit configured to create a structure of a semantic frame by analyzing a natural language question that is input;
a question-intermediate expression creation unit configured to create a question-intermediate expression of a lexicon level based on the semantic frame;
a knowledgebase-specialized query creation unit configured to create a query used to search in knowledgebase that is a subject of search, based on the question- intermediate expression; and
a knowledgebase search unit configured to find a correct answer in the knowledgebase that is subject of search based on the query, to provide an accuracy of the correct answer, a confidence of the correct answer and an evidence for the correct answer.
