基于领域本体的业务组件描述与组合匹配 肖 建, 肖 岚, 黄 毅, 郑 力 （清华大学 工业工程系, 北京 100084） 摘 要：为支持各类业务组件的有效共享和快速检索，提出了一种基于领域本体的业务组件描述语 言 OWL-BC，并从领域标准中提炼了业务术语和业务数据分别作为定义功能语义和数据语义的规范， 以解决组件之间的语义异构问题。相应地，为满足业务流程活动的需求，通过功能语义匹配和数据 语义匹配两方面结合对业务组件进行检索，特别是针对数据语义存在的分解和组合关系，提出了基 于概念集合关联度的启发式算法进行组件组合匹配。实验表明，该算法具有良好的效率。 关键词：领域本体; 语义标注; 组件组合; 匹配算法 中图分类号：TH166 文献标识码：A Business components description and composition matching based on domain ontology XIAO Jian, XIAO Lan, HUANG Yi, ZHENG Li (Department of Industrial Engineering, Tsinghua University, Beijing 100084,China) Abstract: To support the effectively sharing and rapidly discovery of various business components, a description language OWL-BC based on domain ontology is proposed. Business terminology and business data are extracted from some business standards, and employed as the basis of functional semantics and data semantics of business components to reconcile heterogeneous semantics problems. Accordingly, to meet the requirement of business activities, functional and data semantics matching approaches are jointly used to discover suitable business components. Considering the decomposition and composition of data semantics, a greedy heuristic based on concept-set relativity is proposed to conduct business components composition matching. The efficiency of the algorithm is validated by experiments. Key words: domain ontology; semantic annotation; components composition; matching algorithm 0 引言 在激烈的竞争中，企业的业务流程必须能够快速应对市场变化，特别是在业务流程再造（Business Process Re-engineering, BPR ）理念的指导下，流程的变化往往带来信息系统结构的变化。为了支持 信息系统的快速、动态重组，从第三方或企业原有的组件库中获得一些立刻能用的功能业务组件来 组成新的信息系统，显然要比开发新的功能模块更为可取。 基于组件的软件工程（Component-Based Software Engineering, CBSE ）正是以此为目的发展起来 并得到广泛应用的，例如 OMG
