In this paper, we describe a logical ontology design pattern that summarizes a relationship and its inverse between two distinguished members of an n-ary relationship.

The authors have implemented FIPA 98 Spec 12: Ontology Service. In addition, we developed a sample application of online shopping service that integrated multiple database schemata using the ontology service to verify and demonstrate the specification and the implementation. In this paper, we briefly introduce FIPA and FIPA Specifications at first. Next, we describe Comtec Agent Platform, on wh...

The proliferation of heterogeneous sources of instances raises a research issue of achieving interoperability through instance matching. In this paper, we propose an efficient algorithm for ontology instance matching by considering the semantic links associated to a particular instance. An instance is specified explicitly with the help of linked concepts, properties and their values in a neighb...

The system we have developed is called POSOLE, or the POSet Ontology Laboratory Environment. POSOLE consists of a set of modules supporting ontology representation, categorization of nodes in the ontology, and analysis. The analysis modules provide support for analysis of the ontological structure, the structure of input queries to the categorization module with respect to that structure, and t...

Conceptual models are built with concepts and relationships between them to reach a unified view of domain problems. There many kinds conceptual developed in different modeling languages, such as class diagrams entity-relationship models. In this paper, the authors have specific meta-model following Ecore standard define These domain-specific can be automatically formalized ontologies using mod...

The civil law system is highly characterized by relationships. The general rule is that any document of this domain is always embedded in a context of the legal order. The legal order can be defined as a set of norms; thus, understanding concepts of a legal norm is important to understanding other legal norms. However, this feature impairs knowledge of the law, since a thorough understanding of...

Support for modularity allows complex ontologies to be separated into smaller pieces (modules) that are easier to maintain and compute. Instead of considering the entire complex ontology, users may bene t more by starting from a problem-speci c set of concepts (signature of problem) from the ontology and exploring its surrounding logical modules. Additionally, an ontology modularization mechani...
