The main objective of the project is to design the conceptual scheme of a research infrastructure supporting the networking of centres for high-quality research in Slavic lexicography, fostering their scientific capacity, integrating their digital resources and opening them up to the European academic community. The project will provide strategies for the coordination, unification and extension of existing digital lexical resources and the creation of new ones, in accordance with the recent advances in the field and the international standards. This will ensure their reusability and interoperability, so that researchers in humanities and social sciences as well as business will have easy access to digital bi- and multilingual dictionaries of Slavic languages. Thus the project will contribute to preserving and supporting the multilingual and multicultural European heritage. In more distant perspective we envisage the creation of a general lexical data base with the possibility of searching entries in any Slavic language, with information on the words’ etymology and correspondences in all Slavic languages and in English. The data base will possess a rich system of links between forms and meanings of words in synchrony and diachrony. An interactive Web portal will enable the supervised extension of the data base by the end users (Wiki-style) and ensure fast growth and relevance to the users’ needs. The partners in the project are research organisations from six European countries whose six national languages belong to the Slavic group: Bulgaria, Poland, Russia, Slovakia, Slovenia and Ukraine. All partners are national centres for high-quality research in lexicography and digital resources. Each partner is responsible for coordinating a part of the work matching their specialisation and experience. The six thematic working groups are designed as fora for discussing specific parts of the project, and the work programme provides a detailed breakup of the task in time.
