TAX FIELD-ORIENTED KNOWLEDGE MAP CONSTRUCTION METHOD AND SYSTEM

摘要

Disclosed are a tax field-oriented knowledge map construction method and system. The construction method combines a top-down approach and a bottom-up approach, and the tax field-covering knowledge map construction system mainly comprises the following modules: a pattern editing module, a data processing module, an information extraction module, a fusion and disambiguation module, a quality assurance module, and a knowledge service module. In the present invention, a tax knowledge map pattern is constructed on the basis of tax knowledge in a tax expert system; information extraction is performed on processed data in accordance with a pattern diagram and according to different types; then, tax knowledge fusion is performed, the sources of knowledge in a tax knowledge map are different, there are problems such as knowledge duplication and relationship redundancy, pattern matching and entity alignment need to be performed, and after the knowledge fusion is completed, the knowledge is stored in a knowledge base; finally, knowledge feedback is performed, and the tax expert system is used to solve knowledge conflicts in the construction of an intelligent tax model. Finally, the problem that the knowledge map is not closely combined with a tax scenario is solved.
