Embodiment Construction

[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Semantic structure recognition method of network information

[0024] On web pages, there are a lot of information that is not related to the subject content of the page, such as advertisements. Useful information and knowledge only exist in certain areas of the page. In the following, we call these areas semantic information blocks. Generally, there are many semantic information blocks on a page, and their semantic structure may be different, expressing different meanings respectively, such as Figure 1A , A group of information in a certain area of ​​the blog page expresses the blogger’s personal information, which has a semantic structure A; in another area is a series of blog posts published by the blogger, with n semantic information blocks, which have a semantic structure B, The preferred embodiment of the present invention can accu...

Abstract

The invention discloses a method and a device for identifying a semantic structure of network information. The semantic structure comprises a plurality of semantic comments of the network page information content related to the semantics, properties of the commented information, and relations among the semantic comments. The method comprises the following steps: storing into a semantic structure tree in the system by defining the semantic structure of a sample page; generating a semantic tree identification command and a semantic tree validity identification command; and storing a semantic structure description file, a semantic tree identification command file and a semantic tree validity identification file in an external storage after the semantic tree identification command and the semantic tree validity identification command are verified. The semantic structure of the network page information, which is defined and identified by the method and the device of the invention, can be used by various systems, such as an information extraction system, a full-text and semantic search system, a commercial information mining system, an information syndication system, a network knowledgebase system and the like.

Description

Technical field [0001] The invention belongs to the semantic network branch of the computer science and technology field, and specifically relates to a method for identifying the semantic structure of network information, which is suitable for network information extraction, full-text search and semantic search, business intelligence mining, information aggregation, network knowledge base establishment and other application fields. Background technique [0002] With the rapid development of the Internet and the Web, the information on the Internet has exploded. In addition to obtaining knowledge and information from traditional media, people are becoming more and more accustomed to seeking help on the Internet. Full-text search technology enables people to retrieve information on the Internet. As long as you enter a few keywords, you can quickly obtain information containing these keywords. However, even with search tools, people still feel that they are slowly losing their way i...
