摘要
针对土地评估系统中评估知识紧密结合模式和松散结合模式的缺点 ,采用评估知识库作为专题数据与程序的接口 ,对评估知识与数据实体的相互关系、评估知识分类、表达。
Traditionally evaluation knowledge is integrated with land evaluation software by tight mode or loose mode. It can not meet the needs that the land evaluation systems can be organized at will in different cities, and entities such as factors and samples can be analyzed by different methods or processes. The evaluation knowledge' s classifications, expressions, storage, integrated mode and the relations with data entities are discussed, and the evaluation repository is designed. Three types of evaluation knowledge: descriptive knowledge, rational knowledge,process knowledge are divided into several subsections such as entities, database structure, fields content, formula parameters and calculating methods etc. They will be expressed as strings and saved in the repository file.
