Logic structure tree construction method based on geoscience branch subject expert knowledge

Abstract

The invention discloses a logic structure tree construction method based on geoscience branch discipline expert knowledge, and the method carries out the improvement of a geoscience thesaurus through17 discipline professional knowledge nodes, and achieves the specialized, unified and systematic expression. Through construction of a geoscience thesaurus, logic structure construction is achieved, and corpus relation three-dimensional expression is achieved. And then informatization analysis is performed by using a geological word segmentation dictionary with the capacity of 40,000 words, corpora in the 40,000 word segmentation dictionary is clearly classifed, and a geoscience thesaurus is perfected so as to achieve three-dimensional construction of the coverage geoscience corpora. By facing the field of geoscience discipline, controlled, normalized and systematic geoscience descriptors are used as basic elements, and each geoscience descriptor is used as a reference system to establisha relationship between words. During retrieval, a certain keyword is retrieved, so that the hypernyms, the hyponyms, the related words and the English words are obtained from the logic structure treebased on the geoscience thesaurus, and one retrieval word is expanded to N retrieval words.

Description

technical field [0001] The invention relates to the technical field of geoscience data structure trees, in particular to a method for constructing a logical structure tree based on expert knowledge of geoscience branches. Background technique [0002] For any professional field, its knowledge model is composed of objects, attribute characteristics, concepts involved in objects and the relationship between them. Summarize and abstract geoscience objects and their relationships to form geoscience concepts, relationships, or rules; express geoscience concepts and relationships qualitatively and quantitatively as attribute information and values; at the same time, attributes and values ​​are used to understand various The expression of things, phenomena or their processes in geoscience is the basis for distinguishing different geoscience concepts and relationships. All kinds of geoscience data are the carrier of the whole geoscience knowledge model. To build a geoscience knowl...

Problems solved by technology

[0005] At present, in the existing technology, the keywords selected by users themselves and the related words found in the query are often non-standardized natural language, and the expression and composition of words are affected by personal factors, and it is difficult to fully obtain synonyms and synonyms of keywords, etc.
