1 What is a Cooperative Information System? A large number of cooperating component systems distributed over large, complex computer and communication networks and working together cooperatively, requesting and sharing information, constraints, and goals.
2 Main contributions of accepted papers Paradigms Methodologies Tools Algorithms Platforms Applications
3 Information integration Use of machine learning techniques for dynamic integration of schemas Comparison of techniques for dynamic maintenance of the decomposition of a global query into local queries Use of similarity techniques for schema matching Extension of methodologies for integration to multimedia schemas Dynamic B2B integration using workflows to model processes Extensions of Object Definition Languages with restructuring and integration operators
4 Information search Machine generation of ontologies and dynamic information seeking Planning and optimization of information search in a complex set of heterogeneous information sources
5 Multi and federated database systems Optimization of distributed integrity constraint checking Extension of the concurrency control model to multidatabase systems Use of mobile agents to improve information retrieval in a GIS
6 Workflow, groupware, CSCW models and systems A workflow query language based on XML A process model and negotiation mechanism for dynamic cross organiza- tional process interconnection A model for synchronous multiuser interaction in cooperative applications
7 Agents Interaction among agents –with different culture and skills –through suggestive agents –A new and efficient multi agent negotiation protocol based on multiple negotiations Very large scale agent systems –Random flexible local matchmaking –Improving the use of local information by using an XML centralized knowledge repository
8 Architectures Peer to peer systems –A flexible and efficient access structure Event/based systems –Improving with semantic features and a flexible architecture for composing services –Extension with content based interaction that use generic constraints and types Collaborative virtual environment –Use of an aspect oriented framework for improving the awareness and user preferences adoption Wrapper mediator architecture –A cost model for wide area application processing
9 Web information systems and e-services An environment for E-service description, composition and matching A repository and matching techniques for XML documents sharing An analysis of behaviour and evolution of electronic markets A marketplace template for inter enterprise cooperation Improved on-line and off-line recommendation system based on collaborative filtering
