文章针对目前不良信息过滤系统缺乏语义分析的问题,结合基于领域本体的概念语义相似度计算模型,构建了一种基于语义分析的不良信息过滤系统。该系统从文档语义分析的角度,将统计和语义两方面因素进行了有效结合。实验证明本文提出的不良信息过滤系统较传统的信息过滤系统在滤全率和滤准率方面都有了一定的改进。
Aiming at the actual ineffective information filtering system lacking of semantic analysis, a kind of ineffective information filtering system based on semantic analysis was constructed by combining domain ontology-based concept semantic similarity computation mode. From the document semantic analysis, the system availably integrates both statistic factor and semantic factor. Compared with the traditional information filtering system, the system proposed in this paper has been obviously improved in the radio of precision and recall.
