BulTreeBank Group

The BulTreeBank Group is working on projects related to Computational Linguistics and Semantic Web. Our main task is to create Language Resources and Tools for Bulgarian. We have worked on creation of a Bulgarian Treebank, POS tagger, Partial Grammar, Text Archive, Domain Ontologies, Lexicons, XML Tools. The BulTreeBank Group is part of the Linguistic Modelling Laboratory (LML), Institute of Information and Communication Technologies , Bulgarian Academy of Sciences. The group originates from BulTreeBank Project. The project was funded by the Volkswagen Stiftung, Federal Republic of Germany under the Programme "Cooperation with Natural and Engineering Scientists in Central and Eastern Europe". The project was carried out mainly at LML in tight cooperation with researchers at the Seminar für Sprachwissenschaft (SfS), Eberhard-Karls-Universitä t, Tübingen, Germany.

CLaRK system - XML-based system for corpora development

The core of CLaRK is an XML Editor, which is the main interface to the system. Besides the XML language itself, we implemented an XPath language for navigation in documents and an XSLT language for transformation of XML documents. CLaRK is based on an Unicode encoding of the information inside the system. The basic mechanism of CLaRK for linguistic processing of text corpora is the cascaded regular grammar processor. Several mechanisms for imposing constraints over XML documents are available. The constraints cannot be stated by the standard XML technology.
