基于本体的情景建模评价研究

Research on Evaluation of Ontology-Based Context Modeling

情景建模是个性化信息服务、环境智能实现的基础。文章通过文献调研法,在已有研究的基础上筛选出19个评价指标,构建一个基于本体的情景建模评价框架。然后文章选择了国内外7个较为典型的情景模型进行比较研究,以检验该评价框架的可行性。评估结果表明当前研究情景本体建模在实体概念方面较为重视,而在系统应用及建模性能方面较为欠缺,主要体现在社交、隐私保护、不确定性处理及概念的简明性方面。

Context modeling is the basis of the implementation of personalized information service and ambient intelligence. 19 evaluation indexes are selected on the basis of previous studies by the method of document investigation. This paper proposes an evaluation framework of ontology-based context modeling. Then 7 context models at home and abroad are compared under this evaluation framework to demonstrate the applicability of the evaluation framework. The evaluation shows that current ontology-based context modeling attaches more importance to concept of entities, but lack comparative analysis on the application and performance of context modeling, which is mainly reflected in the social interaction, privacy protection, the clarity of concepts and ambiguity handling.
