Abstract

The present invention proposes an answer positioning method and device based on in-depth question and answer, wherein the method includes: receiving an input query statement; parsing the query statement to generate a semantic analysis tree corresponding to the query statement; using a pre-established matching library, Match the semantic parsing tree to obtain the alignment probability of the candidate answer in the matching library and the semantic parsing tree; determine the final answer according to the alignment probability. Through the present invention, the process of clicking links and searching for answers in lengthy texts can be avoided by users, the answers required by users can be displayed intuitively and clearly, and the search service requirements of users can be deeply satisfied.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a method and device for locating answers based on in-depth questions and answers. Background technique [0002] Deep Question and Answer (DeepQA) refers to understanding human language, intelligently identifying the meaning of questions, and extracting answers to questions from massive Internet data. [0003] With the rapid development of the Internet, the functions of search engines are becoming more and more powerful, and users have higher and higher expectations for search engines, starting to change from basic relevant web page recall to intelligent question answering. When a user enters a question to be queried through a search engine, the search result that is expected to be obtained is no longer a relevant web page, but an answer to the question can be obtained directly. [0004] However, the existing search engine technology can only provide users with highl...
