Deep question answer-based answer retrieval method and device

Abstract

The invention discloses a deep question answer-based answer retrieval method and device. The method comprises the following steps of: receiving an input query statement; carrying out retrieval according to the query statement so as to obtain a webpage which comprises candidate answers; respectively obtaining a first candidate answer, a second candidate answer and a third candidate answer on the basis of a webpage analysis method, a deep learning method and a template matching method; determining a final answer according to the first candidate answer, the second candidate answer and the third candidate answer; and displaying the final answer. Through the method and device disclosed by the invention, the answers corresponding to the questions queried by the users can be directly displayed in the search result pages, so that the relevancy and correctness of answer retrieval are improved, and the display effect of the research results is improved.

Problems solved by technology

[0004] However, the existing search engine technology can only provide users with highly relevant web pages as search results through information retrieval and document summarization technology. , and extract the desired answer by itself

Therefore, the existing search engine technology does not have an in-depth question and answer function, and cannot directly provide users with answers to questions, and the presentation effect of search results is poor.
