== Overview ==

   The development  of sophisticated 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 2011 covers
   the  broad area of  Computational Logic  and its  applications, with
   special   interest   on   topics   related  with   new   formalisms,
   environments, languages, tools,  and applications.  A non-exhaustive
   list of topics follows:

- 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

== Important Dates ==

    Deadline for paper submission: May 10, 2011
    Notification of paper acceptance: June 10, 2011
    Camera-ready papers: July 1, 2011
    Conference dates: October 10-13, 2011

== Submission Guidelines ==

   All  papers should  be submitted  through the  conference management
   website at:

      http://www.easychair.org/conferences/?conf=epia2011

   Papers should  not exceed fifteen (15)  pages in length  and must be
   formatted according to the information for LNCS authors. Papers must
   be submitted  in PDF (Adobe's  Portable Document Format)  format and
   will  not be accepted  in any  other format.  Papers that  exceed 15
   pages  or do  not follow  the  LNCS guidelines  risk being  rejected
   automatically  without  a  review.   At  least one  author  of  each
   accepted paper  must register for the  conference.  More information
   about the  Springer's Lecture Notes  in Computer Science  (LNCS) are
   available on the Springer LNCS Web site

   The best  papers (the  exact number is  decided by the  EPIA Chairs)
   will appear  in the  proceedings published by  Springer in  the LNAI
   series. The remaining  accepted papers will be  published in a venue
   TBA.
