Abstract

The invention discloses an automatic question answering method and a system thereof. The automatic question answering method comprises the following steps: step A, the information of a question is acquired through the analysis of the question; step B, the query criterion is generated according to the analysis results of the question for retrieval by using the search engine in knowledge source, thus searching out the file collection relating to the query criterion; the file collection is divided into paragraph collections; step C, paragraph collections relating to the query criterion are retrieved in a centralized way from the paragraphs by using the paragraph retrieval method according to the file retrieval results; and the answer of the question is returned from the paragraph collections. The automatic question answering method and the system improve the accuracy of answers and the precision of returning correct results.

Description

technical field [0001] The present invention relates to the fields of knowledge engineering, natural language processing, and computer network information technology, in particular to a document-based automatic question answering method and system. Background technique [0002] The current network contains an increasing amount of information, and people can get answers to a large number of questions from the network. Usually, the network is composed of a large number of hypertexts (web pages). However, it is very difficult for users to quickly locate required information in the network. An important method to solve this problem in the prior art is to use a search engine to search for the required answer to the question through keyword matching. [0003] However, this method usually results in a large number of webpages that contain search keywords but have nothing to do with the answers. Users usually need to manually or further search for relevant webpages in the search re...
