Computational Logic with Applications

The integration of new complex intelligent systems requires more and more sound and appropriate foundations and tools, resulting in new problems and challenges for the computational logic practitioners. Computational logic has been widely used in complex applications in important areas such as the Deductive Databases, Natural Language Processing and Program Analysis, and more recently on the Semantic Web and related Web Tools. These novel applications have exposed the limits of existing approaches, showing the need for research on better languages and more sophisticated implementations of reasoning systems. The COLA thematic track of EPIA 2009 covers the broad area of Computational Logic and its applications, with special interest on topics related with new formalisms, environments, and applications. A list of non-exhaustive topics can be found below.

Topics of Interest

  • Logic based knowledge representation and applications.
  • Declarative semantics of rule languages and applications.
  • Program Analysis, Program Transformation, Validation and Verification, Debugging, Profiling.
  • Implementation of reasoning systems, in particular logic programming, contextual logic programming and tabling systems.
  • Abductive and Inductive Logic Programming
  • Ontologies, Description Logics and integration with reasoning systems.
  • Reasoning with incomplete and uncertain information, including non-monotonic reasoning as well as probabilistic and fuzzy logic programming formalisms.
  • Reasoning on the Semantic Web.
  • Applications: Deductive Databases, Data Integration, Natural Language, Semantic Web, and Web Tools.
