Workshop motivation and aims

Treebanks are a language resource that provides annotations of natural languages at various levels of structure: at the word level, the phrase level, the sentence level, and sometimes also at the level of function-argument structure. Treebanks have become crucially important for the development of data-driven approaches to natural language processing, human language technologies, grammar extraction and linguistic research in general. There are a number of on-going projects on compilation of representative treebanks for languages that still lack them (Spanish, Bulgarian, Portugese,Turkish) and a number of on-going projects on compilation of treebanks for specific purposes for languages that already have them (English).

The practices of building syntactically processed corpora have proved that aiming at more detailed description of the data becomes more and more theory-dependent (Prague Dependency Treebank and other dependency-based treebanks as the Italian treebank (TUT) or the Turkish treebank (METU); Verbmobil HPSG Treebanks, Polish HPSG Treebank, Bulgarian HPSG-based Treebank etc.). Therefore the development of treebanks and formal linguistic theories need to be more tightly connected in order to ensure the necessary information flow between them.

The workshop aims at being a forum for researchers and advanced students working in one or both of these areas. It will be held in conjunction with the summer school „Empiri cal Linguistics and Natural Language Processing“, Flagman hotel, Sozopol, Bulgaria.

Two round-table discussions will be organized on the following topics:

  • the relationship between the syntactic properties of a given language and the choice of linguistic theory for annotation purposes
  • the utility of treebanks for linguistic theorizing
