Method and system for constructing semantic knowledge base in environmental impact evaluation field

Abstract

The invention provides a method and system for constructing a semantic knowledge base in an environmental impact evaluation field, and the method comprises the steps: constructing a professional term knowledge base and a non-professional term knowledge base corresponding to an industry category according to the business demands and industry expert knowledge for each industry category, and for each non-professional term keyword in the non-professional term knowledge base, establishing a fuzzy extraction rule through a regular expression; constructing a quaternary relationship among industry categories, terminologies, rules and keywords, and generating a keyword-rule lexicon according to the quaternary relationship; selecting corresponding professional terms from the keyword-rule lexicon according to the industry category of a target environmental assessment file, and locating a target chapter of the target environmental assessment file and a table and text content corresponding to the target chapter; and extracting target chapters and keywords in forms and text contents corresponding to the target chapters according to rules in the keyword-rule lexicon, scoring the extraction result, and evaluating the normalization of the target environmental assessment file according to the scoring result.

Description

technical field [0001] The invention relates to the field of environmental impact assessment, in particular to a method and system for constructing a semantic knowledge base in the field of environmental impact assessment. Background technique [0002] The writing of the EIA is not standardized, and the phenomenon of inaccurate professional terms occurs from time to time. When the EIA examines and approves projects, it judges whether its overall assessment of the project situation complies with industry standards and specifications based on the EIA report, and screens out non-compliant EIA reports. [0003] Thousands of environmental impact assessment documents are gathered to the Environmental Protection Bureau every month. The existing technical solution is to manually read, approve, and record non-compliant documents one by one, and the workload is huge. There are also some technical solutions in the existing technology that use information extraction technology to autom...

Problems solved by technology

[0003] Thousands of environmental impact assessment documents are gathered to the Environmental Protection Bureau every month. The existing technical solution is to manually read, approve, and record non-compliant documents one by one, and the workload is huge.

There are also some technical solutions in the existing technology that use information extraction technology to automatically extract document information, but the EIA report is different from general documents, it has a unified industry standard specification, and the EIA report is long, including text information and complex table information , the existing technology is difficult to apply to the field of environmental impact assessment
