[show abstract][hide abstract] ABSTRACT: Existing methodologies to increase the efficiency of design of supply chain management (SCM) processes consider cost, quality, function, and technology attributes of products separately. However, there is no integrated information infrastructure to consider these attributes together. We have devised new table structures to combine the four attributes and their relationships organically. Simple ontology concepts for this information infrastructure were introduced, considering the supply chain tree and the structure of attribute–relationship tables, with some restrictions from a general ontology for the semantic Web. Basic database schemas using the designed ontology were created for the information infrastructure for SCM collaboration. A software component architecture that provides interface services to clients and other business logic in future semantic Web services was also developed, based on this information infrastructure and using the component-based software development (CBSD) methodology. We built Servlet classes for Web presentation, and used Enterprise JavaBeans (EJB), Entity Beans and Session Beans for business logic. Examp les to demonstrate our information infrastructure are also described. Experiments using the three platforms provide performance data that show the capability of our server-side software component system.

[show abstract][hide abstract] ABSTRACT: This paper concerns the motivation for and subsequently the analysis of proposed additions, in the form of new operators, to a concept language Ontolog for use in querying a content-based text retrieval system. The expressiveness of the proposed query language introduces the possibility for querying both objects in the base but also mechanisms for direct querying of the ontology, and it furthermore enables the end- user to tailor the evaluation principle of the system by in∞uencing query expansion in the ontology.
