单向性模型下的主题数据库聚合性分析

Aggregation Analysis of Subject Databases Based on Unilateral Model

对主题数据库技术中的亲合性分析方法进行研究,基于单向性模型对该分析方法进行了改进.提出用聚合性分析方法研究主题数据库技术,并用实体之间的聚合度来分析主题数据库,通过聚合性矩阵建立主题数据库,能较为清楚地反映实体之间的相关性和趋向性.通过实例对实体之间的相关性进行了分析,表明实体聚合度的提出简化了分析过程,利用聚合性矩阵可以更清楚地观察到实体关系的紧密程度,聚合性分析方法有利于理解和分析实体关系,达到清晰实体关系和简化计算的效果.

<Abstrcat>The relative analysis method of subject database technology were studied, and put forward an improved unilateral model and computing formula. We proposed establishing subject databases with aggregation matrixes, analyzing subject databases on the aggregation level of entities and studying subject database technology in aggregation analysis method, so that the relativity and tendency of entities could be clearly reflected. We came to know that the analyzing process could be predigested with the aggregation level of entities, and the compactness of entities could be obviously observed with aggregation matrix based on relatives about the activities of enterprise of a real instance. It is advantageous to the comprehension and study of the connection of entities by means of aggregation analysis, and the relation of entities can be easily understood in theory and predigested in practice.
