Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0038] figure 1 A schematic diagram of a device for indexing based on text information is shown according to one aspect of the present invention. The index building device 1 includes information determining means 101 , topic extracting means 102 , label determining means 103 and index building means 104 .

[0039] Wherein, the information determining means 101 determines the structured information according to the text information. Specifically, the information determining means 101 obtains the text information through interaction with data sources, such as encyclopedia data, etc., and then, by structuring the text information, such as analyzing the catalog information, subtitles, etc. Directory information, etc., from which structured information is determined.

[0040] For example, by interacting with encyclopedia data such as Baidu Encyclopedia and Inte...

Abstract

The invention provides a method and equipment for building indexes and matching inquiry input information of a user. According to text information, structural information is determined and subject words are extracted; according to a subject corresponding to the subject words, label words corresponding to the subject are determined; and the indexes are built form the subject words and the label words. Moreover, the subject words and the label words are obtained through analysis of the inquiry input information input by the user, matching inquiry is carried out in the built indexes, and candidate text information is obtained; according to the semantic matching degree of the candidate text information and the inquiry input information, and target text information matched with the inquiry input information is determined. Compared with the prior art, on the basis of encyclopedia or other network resource knowledge, extracting of subjects and titles is carried out, effective description of resource knowledge content is formed, and accordingly semantic searching of the resource knowledge is more efficient, the searching requirements of the user for complicated descriptions which the user cannot accurately express by means of key words are met, and use experience of the user is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a technology for indexing and matching user query input information. Background technique [0002] In the process of using search engines, people often don’t know what keywords to input to express their thoughts.
