知识库是集团企业云制造平台中知识服务的重要基础,知识库的质量直接决定着知识服务的质量。目前单一分散的知识库不能提供统一的知识资源全局视图,不利于知识资源的共享。多知识库整合技术已经成为该领域的研究热点之一。提出一种基于知识库分割的多知识库整合方法,采用基于蚁群聚类的分割策略,将知识库有效划分为知识块集。在知识块间利用语义概念映射生成知识块间映射图,从而实现多知识库整合。通过对算法的时间复杂度进行分析,表明该方法在时间复杂度方面要优于基于最小概念集的多知识库整合方法;实验结果也表明该方法在运行性能方面明显优于已有的方法。
知識庫是集糰企業雲製造平檯中知識服務的重要基礎,知識庫的質量直接決定著知識服務的質量。目前單一分散的知識庫不能提供統一的知識資源全跼視圖,不利于知識資源的共享。多知識庫整閤技術已經成為該領域的研究熱點之一。提齣一種基于知識庫分割的多知識庫整閤方法,採用基于蟻群聚類的分割策略,將知識庫有效劃分為知識塊集。在知識塊間利用語義概唸映射生成知識塊間映射圖,從而實現多知識庫整閤。通過對算法的時間複雜度進行分析,錶明該方法在時間複雜度方麵要優于基于最小概唸集的多知識庫整閤方法;實驗結果也錶明該方法在運行性能方麵明顯優于已有的方法。

Knowledge base is an important foundation of knowledge services in the Group’s Enterprise Cloud manufac-turing platform.As a result,the quality of the knowledge base directly determines the quality of knowledge services.Sin-gle dispersed knowledge base cannot provide a unified global view of the knowledge resources,which is not conducive to the sharing of knowledge resources.Multiple knowledge bases integration technology has become one of the focuses.An efficient integration of multiple knowledge bases method based on knowledge blocks is proposed,which divides a knowl-edge base into a set of blocks through an improved ant colony clustering algorithm.Then,the mapping between blocks is based on computing semantic similarity of candidate mapping entity pairs are selected from the block mapping result. Through the algorithm’s time complexity analysis,the time complexity is better than the method of integration based on the minimum set of concepts knowledge base.The results also show that the operating performance of the method is obviously superior to existing methods.
