This volume contains the papers presented at the 3rd International Symposium onFoundationsofInformationandKnowledgeSystems(FoIKS2004), whichwas held in Castle Wilhelminenberg, Vienna, Austria, from February 17th to 20th, 2004. FoIKS is a biennial event focussing on theoretical foundations of information and knowledge systems. It aims at bringing together researchers working on the theoretical foundations of information and knowledge systems and attracting researchers working in mathematical ?elds such as discrete mathematics, c- binatorics, logics, and ?nite model theory who are interested in...

This volume contains a selection of papers presented at the 15th International Conference on Applications of Declarative Programming and Knowledge M- agement, INAP 2004, and the 18th Workshop on Logic Programming, WLP 2004, which were held jointly in Potsdam, Germany, from March 4th to 6th, 2004. Declarative programming is an advanced paradigm for the modeling and solving of complex problems. This speci?cation method has become more and more attractive in recent years, for example, in the domains of databases, for the processing of natural language, for the modeling and processing of...

This book constitutes the thoroughly refereed post-conference proceedings of the 18th International Conference on Applications of Declarative Programming and Knowledge Management, INAP 2009, held in Evora, Portugal, in November 2009. The 12 revised full papers presented together with 2 invited talks were carefully reviewed and selected during two rounds of reviewing and improvement. The conference comprehensively covers the impact of programmable logic solvers in the internet society, its underlying technologies, and leading edge applications in industry, commerce, government, and societal...
