4th International Conference on Formal Ontology in Information Systems Topics We seek high-quality papers on a wide range of topics. While authors may focus on fairly narrow and specific issues, all papers should emphasize the relevance of the work described to formal ontology and to information systems. Papers that completely ignore one or the other of these aspects will be considered as lying outside the scope of the meeting. Topic areas of particular interest to the conference are: Foundational Issues * Kinds of entity: particulars vs. universals, continuants vs. occurrents, abstracta vs. concreta, dependent vs. independent, natural vs. artificial * Formal relations: parthood, identity, connection, dependence, constitution, subsumption, instantiation * Vagueness and granularity * Identity and change * Formal comparison among ontologies * Ontology of physical reality (matter, space, time, motion, ...) * Ontology of biological reality (genes, proteins, cells, organisms, ...) * Ontology of mental reality (mental attitudes, emotions, ...) * Ontology of social reality (institutions, organizations, norms, social relationships, artistic expressions, ...) * Ontology of the information society (information, communication, meaning negotiation, ...) * Ontology and natural language semantics, ontology and cognition, ontology and epistemology, semiotics Methodologies and Applications * Top-level vs. application ontologies * Role of reference ontologies; Ontology integration and alignment * Ontology-driven information systems design * Requirements engineering * Knowledge engineering * Knowledge management and organization * Knowledge representation; Qualitative modeling * Computational lexica; Terminology * Information retrieval; Question-answering * Semantic web; Web services; Grid computing * Domain-specific ontologies, especially for: Linguistics, Geography, Law, Library science, Biomedical science, E-business, Enterprise integration, ... Deadlines and Further Information * Electronic abstracts: May 1, 2006 * Final submissions: May 5, 2006 * Acceptance Notification: June 26, 2006 * Submission of camera-ready paper: July 28, 2006 Submitted papers must not exceed 5000 words (including bibliography).
