Embodiment Construction

[0021] figure 1 It is a flow chart of an embodiment of the method for building a business domain knowledge base provided by the present invention. Such as figure 1 As shown, the execution subject of the following steps may be a terminal or server with a data processing function, or one or more modules or chips on the terminal or server. The business domain knowledge base construction method specifically includes:

[0022] S101. Create an ontology of a business domain, where the ontology of the business domain includes concepts;

[0023] Among them, ontology is a standardized description of domain concepts and the relationship between concepts. The so-called ontology of the business domain in this solution can describe the concept of a business domain and the relationship among the concepts. When constructing the business domain knowledge base, the ontology of the business domain can be created through the ontology modeling tool first, and then the database can be construct...

Abstract

The invention provides a business domain knowledge base building method and device. The business domain knowledge base building method comprises creating a business domain ontology which comprises concepts; utilizing the concepts included in the business domain ontology as first key words respectively and searching information items related to the concepts; building retrieve items of a business domain according to the concepts included in the business domain ontology; storing content corresponded information items in every retrieve item in a business domain knowledge base. An embodiment of the business domain knowledge base building method and device effectively solves the technical problem that the efficiency of people searching information from the existing knowledge base is low in the prior art.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a method and device for constructing a business field knowledge base. Background technique [0002] In the prior art, the method of constructing the knowledge base adopts a large number of manual searches of existing network information resources to construct knowledge bases in different business fields. When a search engine searches for resource information in the knowledge base, the knowledge base will contain search keywords All web pages of are returned one by one, giving a large number of search results from a grammatical point of view. [0003] However, in the prior art, the semantic information of each page needs to be analyzed and interpreted by the searcher himself, so the search efficiency is low. Contents of the invention [0004] The invention provides a method and device for constructing a business domain knowledge base, which is used to solve the tec...
