Commit-Time Requirements for an Ontology Server

An ontology is recognized as the solution for the integration of information systems. The environment of interoperation may involve many players who have agreed to commit to the ontology in order to maintain their system of speech acts and institutional facts in conformance with the coordinated system. When this interoperating community is established, it can generate a large number of institutional facts due to different range of players who can request different facets of information. In this light, however, how those players commit to ontology is still unclear. This paper discusses what sort of requirements that we need to assist how the players commit to the ontology. The approach of this paper is theoretical which is based on the literature of the concepts of speech acts and institutional facts and a case study of the Olympic games. As a result, we have defined several important commit-time requirements to explain situations of players committing to ontology in the context of ontology-based interoperation of information systems

UML-based DEMO Profiles as Metaconcepts for Interlocking Institutional Worlds

An information system supporting an organisation is based on concepts from the organisation\u27s institutional world. An institutional world consists of a collection of speech acts and institutional facts . For a group of information systems to interoperate, the organizations responsible for these systems must first agree on what the words mean in the interoperation. This agreement is called an ontology. The ontology is generally defined as an explicit specification of a conceptualization . One of the major uses of ontology is to support interoperation of information systems. Many institutions whose systems are to interoperate are not fully autonomous; they do sometimes cooperate with each other, so that their institutional worlds will interlock therefore interlocking ontologies . Modeling interlocking institutional worlds (IWs) requires a dedicated representation system that gives a formal model which is the specification of institutional facts as well as the specification of speech acts . The ontology is the specification of institutional facts. However, we do not have a system that can give a formal model for the speech acts. Therefore, this paper adopts a synthesis approach to propose the UML extension for modeling speech acts in the context of interlocking institutional worlds. DEMO is one of the most popular Language Action Paradigms (LAP)-based methodologies based on speech act theory so is close to the concept of IWs. The UML is a standard modelling language in the world of information system development and currently there is a growing interest in its adoption as a language for conceptual modeling and business process representation. Taking advantage of the fact that UML is an OMG standard and its use is growing quickly, this paper proposes UML-based DEMO profiles purposely for modelling IWs
