- 345 sameAs 345.
- 345 abstract "We propose a new dynamic constraint optimization problem (COP) formalization for Web services composition problem that permits extension of the original abstract workflow (in case failure) based on the OWL-S service profile description of the underlying semantic Web services and using OWL-S control constructs. Moreover, we have developed a novel, human-centered, agent-based protocol able to find "satisfying" solutions for this problem in real time. This protocol allows restriction and/or relaxation within the original workflow through addition and/or removal of new sub-tasks, deals with a dynamic environment, and uses incomplete, uncertain information.".

- 349 abstract "A current major obstacle to the development of ontologies in support of the Semantic Web is the inability to handle very large ontologies. We propose a solution which consists in augmenting the functionality of a relational DBMS to include the reasoning mechanisms (implemented as stored procedures) that are the essence of ontology management. As a result, a single system is used to store, query, update, and reason about a very large ontology. The OntoMinD prototype we have developed shows very promising performances, according to our tests with the LUBM benchmark.".

- 356 abstract "This paper proposes WebKER, a system for extracting knowledge from Web documents based on domain ontologies and suffix-array-based wrapper learning. It also gives the performance evaluation of this system and the comparison between querying information in the Knowledge Base (KB) and querying information in the traditional database. Moreover, the outstanding-wrapper selection and a novel method for linking and merging the knowledge are also presented.".
