DelphinCst

The Centre for Language Technology, or CST, (www.cst.dk) at the University of Copenhagen works with many areas of human language technology, both at the European level and within Denmark. Our research activities include formal grammatical descriptions of Danish (both LFG and HPSG), lexicography, machine translation, evaluation of HLT products, text proofing tools, language technology in multimodal systems and content-based querying.

We have developed a medium-size Danish grammar in the LKB system, which has been used for parsing of user queries and text fragments in the Danish project Ontoquery (www.cst.dk/ontoquery) and the EU project MOSES (www.cst.dk/moses). In both projects, we have used PET to run the grammar.

In addition, a number of satellite grammars are developed in LKB and related platforms. CST participated in the Scandinavian Network of Machine Translation and Grammar Engineering, as a result of which a small-coverage translation system was developed for Mainland Scandinavian. Finally, a number of CST researchers are engaged in empirical and formal studies of HPSG. Some of this work aims at defining formally restrictive fragments of HPSG without loss of empirical adequacy.
