基于群体行为的协同构建本体可信度研究

摘要

Aiming at solving the possible unpleasant situation of low-quality ontology caused by ordinary users participation in ontology collaboratively building,an ontology collaboratively building method based on group activities is presented. In the method the basic units s, p and o of triples forming ontology are regarded as the smallest knowledge objects of group behaviors, based on which the method intro-duces the reliability tree of ontology module ( RTOM) and virtual level, and nodes reliability of RTOM t is integrated into the reliability of ontology module. Dynamical computing method of multi-domains triple reliability is discussed in detail from the dimensions of group rat-ing and consumption behaviors, and finally the method is simulated and analyzed. The test shows that the method can better represent the multi-level, multi-granularity, multi-domains ontology reliability, and thus dynamically remove the low-quality ontology.%针对普通用户参与本体协同构建的可能会导致本体质量低的问题，提出一种基于群体行为的协同构建本体可信度计算方法。该方法将构成本体三元组的基本单位s、p、o作为群体行为的最小知识对象，在此基础上引入本体模块可信度树和虚拟层，综合可信度树结点可信度的本体模块可信度。从群体评分和消费两个维度详细讨论了多领域三元组可信度动态计算方法，最后进行仿真分析。仿真实验表明该方法能够较为全面地反映多层次、多粒度、多领域的本体可信度，动态地去除低质量本体。
