This paper describes an approach to semantic document retrieval geared towards cooperative document management. In our conceptual modeling approach, a semantic modeling language is used to construct a domain model of the subject domain referred to by the document collection. This domain model is actively used for the tasks of document classification and(More)
Modeling existing and future business processes is crucial to the outcome of large-scale reengineering projects. The use of parameterized or standard components does not render business models redundant, but shifts the modeling focus even more from technical aspects to the real-world business processes. In current reengineering projects, however, there is(More)
This paper conducts an empirical analysis of a semiotics-based quality framework for quality assuring information models. 192 participants were trained in the concepts of the quality framework, and used it to evaluate models represented in an extended Entity Relationship (ER) language. A randomised, double-blind design was used, in which each participant(More)
The overall goal addressed in this paper is to improve semantic interoperability in heterogeneous systems by means of establishing mappings between relevant domain ontologies. The mappings are discovered based on the technique of semantic enrichment through extension analysis, i.e. using instance information of the ontology to enrich the original ontology(More)
This paper describes how the CAGIS environment can be used to manage work-processes, cooperative processes , and how to share and control information in a distributed, heterogeneous environment. We have used a conference organising process as a scenario and applied our CAGIS environment on this process. The CAGIS environment consists of three main parts: a(More)
