Method for searching structured data and search engine system for implementing same

Abstract

The invention provides a search engine system which comprises a structured data memory bank, a demand analysis module and a searching assembly, wherein the structured data memory bank is used for storing structured data; the structured data comprises attribute values corresponding to a plurality of attribute tags; semantic templates are also stored in the memory bank; the semantic templates comprise the attribute tags; the demand analysis module is used for receiving a query word expression from a client and determining the corresponding semantic template according to the query word expression; and the searching assembly is used for searching the structured data memory bank so as to obtain the structured data to be searched. The search engine system provided by the invention analyzes the search expression of a user through the semantic templates so as to exactly know a biggest demand of the user and provide a most suitable mode expression capable of meeting the demand of the user for the user, and thus, the user obtains good using experience, the searching efficiency is improved and the network flow is saved.

Description

technical field [0001] The invention relates to search engine technology, in particular to a search method for structured data and a search engine system for realizing the search method. Background technique [0002] The rapid development of the Internet provides people with a new carrier for information storage, processing, transmission and use, and network information has quickly become one of the main channels for people to obtain knowledge and information. While such a scale of information resources incorporates almost all the knowledge possessed by human beings, it also brings the problem of how to fully develop and utilize resources for users of resources. The search engine came into being precisely under this demand, and it assists network users to find information on the Internet. Specifically, search engines use specific computer programs to collect information from the Internet according to certain strategies, and after organizing and processing the information, p...
