Network search method based on semantic web technology

Abstract

The invention discloses a network search method based on a semantic web technology, and belongs to the technical field of design and development of local area network search engines. The network search method based on the semantic web technology comprises the specific steps that 1, a user situation model is constructed; 2, the situation model and a search engine are integrated; 3, the similarity of keyword vectors and concept keyword vectors is calculated; 4, target concepts are matched to obtain a target concept set; 5, the frequency of candidate keywords is limited; and 6, the target concepts are clustered. According to the network search method, by integrating the user situation model with the search engine, user situation information analysis and utilization in an information searching service are greatly enhanced; and by adopting the semantic web technology, a computer and human can well cooperate to complete work, and the structure and the characteristic of the user situation information are described in a formalized mode to be transformed into the form that the computer can understand and used by the search engine.

Description

technical field [0001] The invention relates to the technical field of design and development of a local area network search engine, in particular to a network search method based on semantic web technology. Background technique [0002] At present, the main tool for users to query information on the Internet is the search engine. Intuitively speaking, a search engine is a software system that runs on the Internet. It collects information from the Internet according to certain strategies and uses specific computer programs. Displayed to the user through a specific user interface. [0003] Nowadays, the rapid development of information technology provides people with a broader sharing platform. Network retrieval has become a common channel for people to obtain information. Classification and retrieval problems. However, the traditional keyword-based retrieval method, because of ignoring the semantic information contained in the keyword itself, has a low recall rate and pre...

Problems solved by technology

[0004] The purpose of the present invention is to provide a network search method based on Semantic Web technology, to solve the traditional keyword-based retrieval method proposed in the above-mentioned background technology, because the semantic information contained in the keyword itself is ignored, and the result is relatively low. The recall and precision rates are becoming less and less suitable for the needs of retrieval
