ABSTRACT To construct large scale ontologies, two major approaches are discussed by many researchers. One is a cooperative construction of ontologies, and the other is a modularization of ontologies. To combine these two approaches, this paper discusses a framework for supporting cooperative ontology construction based on dependency management among modularized ontologies. In such a situation, one of the key issues is the maintenance of consistency among inter-dependent ontologies because each ontology is revised asynchronously by different developers. In order to realize consistent development of ontologies, the framework provides two functions: to manage the dependencies between ontology modules and to keep and restore consistencies between them when they are influenced by changes of other modules. Furthermore, we outline an implementation of our framework in our environment for building/using ontology: Hozo.

    ABSTRACT: Resolving semantic ambiguities in electronic business-services (eBS) during their discovery in broker systems is essential for th e setup and enactment of business-to-business (B2B) collaboration. These ambiguities do not merely result from differently understood terminology, but also f rom specifications for- mulated in other human languages than English. Using third-party information sources in differing human languages such as blogs, wikies, RSS feeds to find out more about eBS, additionally requires semantic screening, ranking, and merging. Such third-party information helps organizations to estab lish trust in an eBS they discover in an anonymizing, electronic broker. Here, ontol ogies lend themselves for resolving the ambiguities of eBS descriptions and of the ir related third-party information from the Web. While tool support exists for the development and maintenance of ontologies, the question remains unanswered what the degree of utility is of these tools in the context of ambiguity resolut ion while discovering eBS. In this paper, we fill the gap by performing an ontology-t ool evaluation that allows a comparison of their utility.

    ABSTRACT: Traditional knowledge sharing of distributed ontologies can be obtained by adopting ontology integration and mappings. It is difficult to maintain such ontology based knowledge systems because there needs a global ontology or the maintenance of complex ontology mapping relations. In this paper, a novel approach based on ontology context immigration (OCI) is proposed for knowledge sharing of distributed ontologies. As for a local semantic term based on distributed ontologies, an appropriate ontology context of the term is specified, which can be used to eliminate semantic heterogeneity between relevant semantic terms of distributed ontologies. The experimental results also show that it is efficient. This approach does not require the support of a global ontology or the maintenance of complex ontology mapping relations, and thus has a better maintainability and scalability.

    ABSTRACT: The widespread use of ontologies in the last years has raised new challenges for their development and maintenance. Ontology development has transformed from a process normally performed by one ontology engineer into a process performed collaboratively by a team of ontology engineers, who may be geographically distributed and play different roles. For example, editors may propose changes, while authoritative users approve or reject them following a well defined process. This process, however, has only been partially addressed by existing ontology development methods, methodologies, and tool support. Furthermore, in a distributed environment where ontology editors may be working on local copies of the same ontology, strategies should be in place to ensure that changes in one copy are reflected in all of them. In this paper, we propose a workflow-based model for the collaborative development of ontologies in distributed environments and describe the components required to support them. We illustrate our model with a test case in the fishery domain from the United Nations Food and Agriculture Organisation (FAO).
