摘　　要：针对知识推送问题,建立了基于场景的知识推送模型、场景驱动的知识库模型。采用语义相似度的方法计算知识使用场景的相似度,通过知识使用场景与知识的映射,实现与任务场景最匹配知识的推送。以某气门生产企业的工艺知识推送为例验证了该知识推送方法的可行性。To solve the problem of knowledge pushing, the models of knowledge pushing based on knowledge usage scenario and knowledge base drove by usage scenario are proposed. Semantic similarity is used to calculate the similarity between knowl- edge usage scenario and knowledge index. According to the relationship between knowledge and knowledge usage scenario, knowledge is recognized and pushed to the task. A case study of process knowledge push in a valve production enterprise is pro- vided to demonstrate the feasibility of this method.

关 键 词：知识使用场境 知识推送 语义相似度
