| Abstract | As the lifecycle of information technology becomes shorter and the characteristics of related personnel and projects become more diversified, there come to transformations of e-Business environments in these days. Moreover, the heterogeneous and distributed information of e-Business environments are not machine-understandable. In order to integrate the heterogeneous and distributed information of e-Business environments, self-describing protocols or integrative software design methodologies are needed and ontology would play an important role. In this study, the author proposes a framework for e-Business integration, which is based on a collaborative interoperable environment and the syntactic/semantic integration. The environment should be constructed by meta-modeling and employment of agents. The author classifies the agents by interface agents for message exchange, task agents for intra-process, and information agents for interconnection of legacy systems. The author is responsible for managing semantics by using the ontology and could make correct and automatic transactions between them. And the author uses DAML (DARPA Agent Markup Language) for specification of meta-models and builds ontology through the systematic approach. The ontology is represented in data and process meta-models, separately. The meta-models are built in a layered architecture based on the IRDS (Information Resource Dictionary Standard ISO/IEC 10027:1990) framework. The layers in this study are DAML layer, PSL-ontology layer, e-Business application layer, and XML Schema layer. The PSL-ontology layer is presented in modeling the process. An illustrative example of e-Business scenario is given, which is quoted from the RosettaNet standard and is concerning order management, such as quotation and purchase order. And the ontology is applied to the scenario. Finally, the methodologies for using and evaluating ontology are proposed, which are about the information retrieval, inferences, and evaluation criteria. And then, a prototype with database is implemented. By defining, sharing and managing resources and business-processes on the proposed ontology-based framework, it is possible to get rid of the cause of redundancy and inconsistency in e-Business environments. |
