Question answering system and method for structured knowledgebase using deep natural language question analysis |
摘要 |
Disclosed are a question answering system for structured knowledgebase using deep natural language question analysis, and a method thereof, the question answering system for structured knowledgebase using deep natural language question analysis includes 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. |

1. A question answering system for structured knowledgebase using deep natural language question analysis, the question answering system comprising:
one or more processors that process computer executable program code embodied in computer readable storage media, the computer executable program code comprising: deep natural language question analysis program code that creates a structure of a semantic frame by analyzing a natural language question that is input; question-intermediate expression creation program code that creates a question-intermediate expression of a lexicon level based on the semantic frame; knowledgebase-specialized query creation program code that creates a query used to search in a knowledgebase that is a subject of search, based on the question-intermediate expression; and knowledgebase search program code that finds a correct answer in the knowledgebase that is the subject of search based on the query, and that provides an accuracy of the correct answer, a confidence of the correct answer and an evidence for the correct answer. |
