Projects

1988 - 1992

"Advanced Computer Technologies in the Creation of Large Linguistic Knowledge Bases (for Slavonic Languages)". Sponsored by the Bulgarian National Science Fund in cooperation with the Institute of Russian Language, Russian Academy of Sciences, Moscow, Russia.

The aim of the project was to create a computer dictionary of Bulgaria with 32 000 lexemes and a Russian dictionary with 100 000 lexemes.

I was responsible for the development of the MORPHO-ASSISTANT software system for modelling Bulgarian and Russian morphology which would serve the compilation of large dictionaries. Within this task, I developed a model for the acquisition of lexical information on the basis of the classification of lexemes with respect to a set of morphological classes. The classification itself was done by means of an index over the morphological classes, such that a lexicon writer need only provide minimal information about a particular word in order for it to be correctly classified. The MORPHO-ASSISTANT system can be adapted for use with other inflectional languages.

More specifically, I was responsible for the representation of morphological data; for creating algorithms for the analysis and synthesis of word forms and for processing of wrong word forms; I also developed tools for the acquisition and editing of lexical information and for supporting the building of the lexicon. I fully designed and implemented the software.

December 1993 - December 1994

"Interaction Among Knowledge Bases", sponsored by the Fund Eureka and the Bulgarian Ministry of Science and Education.

The primary goal of this research was to expand further the ideas behind the MORPHO-ASSISTANT lexical acquisition tool. The lexicon and the grammar were viewed as two knowledge bases that interact in the process of their common usage (e.g. in the parsing of a sentence). The project researched methodologies for establishing semantic correspondences between knowledge bases represented in various knowledge representation languages. This methodology was then applied to the problem of using the ACLRN knowledge representation language as a query language for relational databases. The problem was overcome by building an ACLRN knowledge base together with a semantic correspondence between the terminological part of the knowledge base and the relational schemata of the relational database.

I was the project leader.

January 1995 - December 1996

"Representation of Control Information", sponsored by the Fund Eureka and the Bulgarian Ministry of Science and Education.

The project built an explicit representation of the control of inference procedures in implementations of declarative knowledge representation languages. This representation allows an expert in some knowledge domain to encode control information to suit specific tasks over that domain. The project developed a special normal form for SRL (Speciate Reentrant Logic developed by Paul John King) theories and an indexing technique over such normal forms. The indexing technique enables the automatic reordering of a theory so that the theory exhibits certain relations between elements of the knowledge represented by the theory. The indexing technique also supports the reorganisation of a theory to suit those requirements of a user that are based on knowledge that is not represented by the theory, such as the environment in which the theory is to be used and the type of problem to be decided.

I was the project leader

April 1995 - June 1997

"MULTEXT-EAST" - a joint project under the Copernicus Programme of the European Union.

In the project I was responsible for preparation of the lexicon of the Bulgarian part. It is a full form dictionary in which each word form contains the appropriate grammatical information and a pointer to the lexeme. It is based on the morphological dictionary of Bulgarian language, created in cooperation with Dimitar Popov and Svetlomira Vidinska from the Institute of Bulgarian Language, see the next item

June 1995 - October 1998

"Creation of a Morphological Dictionary of Bulgarian Language"

On the basis of two machine-readable dictionaries of Bulgarian language, a methodology for extraction of the relevant linguistic knowledge about the inflectional morphological classes of words was developed. Starting with a minimal grammar of Bulgarian word formation - sufficient to analyse the information in the two machine-readable dictionaries - the project arrived at a complete morphological grammar and a morphological dictionary with 75 000 entries, which together can be used as the morphological component in a system to automatically process Bulgarian language. The dictionary and the grammar are published as a book (see Publications). I was responsible for developing the methodology for combining the knowledge from the two dictionaries and the formation of the morphological classes and classification of the lexical items. I also implemented the software for the creation of the dictionary.

January 1998 - July 2000

"CONCEDE" - a joint project under the Copernicus program of the European Union

In the project I am responsible for encoding and validation of Bulgarian machine readable dictionaries in SGML schemata for lexical knowledge bases. I implemented software modules for recognition of the structures in the lexical items in the machine readable dictionaries and converting these structures in SGML markup.

October 1998 - September 2000

"Tübingen-Sofia International Graduate Programme in Computational Linguistics and Represented Knowledge (CLARK)" - a joint project between the Seminar für Sprachwissenschaft (SfS), Eberhard-Karls-Universität, Tübingen, Germany and the Linguistic Modelling Laboratory.

The Tübingen-Sofia International Graduate Programme in Computational Linguistics and Represented Knowledge (CLARK) provides a joint teaching and research facility wherein doctoral and master's students primarily from Bulgaria and Central and Eastern Europe (CEE) pursue their researches in the interdisciplinary field of computational linguistics and knowledge representation. The programme is funded by the Volkswagen-Stiftung.

The education of the students follows an apprenticeship model. That is, the students pursue their individual researches within a collaborative project-based research environment. At the moment, there are two sub-projects in the framework of CLARK: "XML-based Tool for Corpus Linguistics" and "Neural Networks for MorphoSyntactic Disambiguation".

I was the scientific coordinator of the programme for Bulgaria
