Abstract

The invention discloses an information retrieval method and apparatus, belongs to the field of the internet, and aims to improve the accuracy of a retrieved result of a problem to be solved by a user. The method comprises the steps of receiving an input to-be-solved problem; determining the technical field which the to-be-solved problem belongs to; according to a pre-established knowledge base in the technical field, determining a target document matched with the to-be-solved problem in the technical field, wherein the knowledge base comprises problem objects, knowledge objects, document objects, corresponding relationships between the problem objects and the knowledge objects, and corresponding relationships between the knowledge objects and the document objects, and the knowledge objects are selected from one part of the problem objects; and returning the target document. The method and the apparatus are used for answering the to-be-solved problem.

Description

technical field [0001] The present application relates to the field of the Internet, in particular to an information retrieval method and device. Background technique [0002] With the rapid development of the Internet, users are more and more inclined to obtain answers to questions by asking questions on the Internet. After obtaining the user's question, the search engine will search based on one or more keywords appearing in the question, and return results matching the one or more keywords. [0003] However, it is very difficult for a machine to understand a human question, and the result obtained through the above method may not be the result that the user wants to obtain, resulting in low retrieval accuracy. Contents of the invention [0004] The embodiment of the present application provides an information retrieval method and device, so as to improve the accuracy of the retrieved results of the user's problem to be solved. Described technical scheme is as follows:...
