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.
