Abstract: To support effective sharing and quick searching of various business components, a description language named Web Ontology Language for Business Component (OWL-BC) based on domain ontology was proposed. Business terminology and business data were extracted from some business standards, and were employed as the norms for defining functional semantics and data semantics of business components to solve heterogeneous semantics problems. Accordingly, in order to meet the requirements of business activities, functional and data semantics matching approaches were jointly used to search for suitable business components. Considering the decomposition and composition of data semantics, a greedy heuristic based on concept-set correlation was proposed to conduct business components composition matching. Efficiency of the algorithm was validated by experiments.
