The involvement in NLP research in the Institute of information Technologies - BAS is tightly connected to the basic research topics at the Artificial Intelligence Department - Knowledge Representation and Logic Programming. It has begun a few years ago with the development of the Net-Clause Language (NCL). NCL is a distributed logic programming language, based on data-driven computation and spreading activation. A formalism for grammar representation with a built-in parser has been developed based on NCL. It offers distributed knowledge representation and processing, and a data-driven spreading activation control scheme. Grammars, described in the formalism, are mapped into network models and can be directly executed (parsed) as network programs in a distributed data-driven manner. The parsing scheme utilizes the NCL default reasoning mechanism. (NCL is available by anonymous ftp from the University of Georgia AI archive ai.uga.edu, directory ai.misc) The research and development activities in the AI department are currently oriented also towards hypertext and multimedia systems and cover application of knowledge-based methods and techniques in the presentation and retrieval of multimedia documents.

The AI Department was partner in the following CEC funded projects: 1. Joint European Project in University education in AI, TEMPUS - JEP 1728 (1991-1994) 2. Joint European Project in Knowledge-based Systems TEMPUS - JEP 1497 (1991-1994) 3. Joint European Project in University education in Computer Science for business, social and humanitarian specialists, TEMPUS - JEP 7272 (1994-1997) 4. Pan-European Scientific Network in Inductive Logic Programming (ILPNET) PECO 92, contract No. CIPA3510OCT920044 (1993-1996) 5. INCO-COPERNICUS PL 1104-96 AGILE - Automatic Generation of Instructions in Languages of Eastern Europe. 6. . INCO-COPERNICUS PL 1060-96 ARCHIMED - Advanced Multimedia System Architectures for Educational Telematics. We are also associate nodes in COMPULOG and MLNET.

Courses on "Methods and Algorithms for NLP" and "Human-Computer Interfaces ic Knowledge-Based Systems" are taught by members of AI Department in 3 Bulgarian Universities.
