Abstract

The invention discloses a method and device for acquiring a search result. The method comprises the steps of receiving a question to be searched; conducting syntactic-semantic parsing on the question to obtain a question subjected to syntactic-semantic parsing; acquiring the knowledge content in a pre-established knowledge base, wherein the knowledge content contains text data obtained after syntactic-semantic parsing is conducted on original text data; obtaining an answer corresponding to the question according to the question subjected to syntactic-semantic parsing and the knowledge content, and determining the answer as the search result. By the adoption of the method, the accuracy of the acquired search result can be improved.

Description

Technical field [0001] The present invention relates to the field of information technology, in particular to a method and device for obtaining search results. Background technique [0002] With the popularization of the Internet, the information on the Internet has become more and more abundant. Now people can easily obtain the information they want through search engines. However, search engines usually search for information based on keyword matching, staying at the surface of the language, making it difficult to further improve the search effect. [0003] In order to overcome the shortcomings of search engines, automatic question answering systems have emerged in the research process of retrieval technology, such as the Xiaodu robot developed by Baidu. In the automatic question answering system, the user does not need to disassemble the question into keywords, but can directly submit the question to the question answering system, which obtains the answer to the question throug...
