Field knowledge base establishment method and device

Abstract

The invention provides a field knowledge base establishment method and device. After a core concept in a current to-be-established field and a target text in which the core concept is located are obtained, at least one non-core concept can be obtained from the target text and the similarity between the core concept and the non-core concept can be obtained; when the similarity satisfies a preset condition, whether the non-core concept is the same to the concept existing in a field knowledge base of the to-be-established field or not is judged; if the non-core concept is different from the concept existing in the field knowledge base of the to-be-established field; the non-core concept is reserved in the field knowledge base of the to-be-established field; the non-core concept is taken as a new core concept, a target text in which the new core concept is located is obtained; the step of obtaining the at least one non-core concept form the target text is carried out again; and after all concepts in the knowledge base of the to-be-established field are obtained, a relation between any two concepts is obtained, so the field knowledge base of the to-be-established field is obtained, and the knowledge base of the to-be-established field is established automatically.

Description

technical field [0001] The invention belongs to the technical field of information processing, and more specifically, relates to a method and device for constructing a domain knowledge base. Background technique [0002] The domain knowledge base is a collection of concepts included in the domain and the relationship between concepts. The concept is the knowledge of its domain, which can be indicated by the entry in the domain. The relationship between concepts is the degree of similarity between concepts, which can be indicated by For example, for the domain knowledge base in the financial field, entries such as finance, economics, and circulation can be used as concepts in the domain knowledge base of their respective fields. With the development of information, the domain knowledge base can make knowledge information and orderly, and make use of the sharing and exchange of knowledge. [0003] At present, the construction of the domain knowledge base is usually completed ...
