摘要/Abstract

摘要： 对面向产品设计的情境信息进行语义描述和分析，将情境概念之间的关联信息作为限制性条件，提出了基于情境约束的知识聚类方法。采用贝叶斯理论对聚类知识进行语义标注，对标注概念与需求概念的综合语义相似度和相关度进行计算，扩展了检索概念范围。实验结果表明，该研究方法可有效提高知识查询与推送的精确度和效率。

关键词: 情境约束, 约束聚类, 贝叶斯理论, 语义标注, 个性化推送

Abstract: Semantic description and analysis of context informations as restrictive condition between contextual concepts for product designs were presented, and a knowledge clustering method was proposed based on context constraints was proposed. Meanwhile, Bayesian theory was used to semantic annotation of clustering knowledges, and the semantic similarity and relevance of annotation concept and demand concept were calculated to expand the scopes of search. Experimental results show that the method may effectively improve accuracy and efficiency of knowledge query and push in the processes of product designs.

Key words: context constraint, constrained clustering, Bayesian theory, semantic annotation, personalized push
