This paper introduces some related concept of faceted classification schema and the definition of facet-weight. An improvement is also proposed in component retrieval schema with facet-weight. The improved schema can effectively raise the recall and precision ratio of retrieval, especially when querying the large-scale component-library. Experiment shows that the improvement is efficient and feasible.%介绍刻面分类模式的相关概念,引入刻面权重的定义,并对基于刻面描述的构件检索模型进行改进.改进后的模型可以有效地提高检索的查全率与查准率,尤其是在对大规模构件库进行查询的时候.实验结果证明了该改进的可行性与有效性.
