Abstract

The invention provides an answer positioning method and device based on deep questions and answers. The answer positioning method comprises the steps that an input query sentence is received; the query sentence is parsed to generate a semantic parsing tree corresponding to the query sentence; a pre-established matching library is utilized to match the semantic parsing tree so as to obtain the aligning probability of a candidate answer and the semantic parsing tree in the matching library; a final answer is determined according to the aligning probability. By the adoption of the answer positioning method, the process that a user clicks a link and find an answer in a tedious text can be avoided, the answer required by the user is visually and clearly displayed, and the search service request of the user is deeply met.

Description

technical field [0001] The present invention relates to the field of Internet technologies, and in particular, to a method and device for answer positioning based on in-depth question answering. 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' expectations for search engines are getting higher and higher. When a user inputs a question to be queried through a search engine, the desired search result is no longer a relevant web page, but an answer to the question can be directly obtained. [0004] However, the existing search engine technology can only provide users with highly relevant web pages as search results through information retrieval and document abstract technology. ...
