A Greek Morphological Lexicon and Its Exploitation by Natural Language Processing Applications

This paper presents a large-scale Greek morphological lexicon, developed at the Software & Knowledge Engineering Laboratory (SKEL) of NCSR “Demokritos”. The paper describes the lexicon architecture and the procedure to develop and update it. The morphological lexicon was used to develop a lemmatiser and a morphological analyser that were exploited in various natural language processing applications for Greek. The paper presents these applications (controlled language checker, information extraction, information filtering) and discusses further research issues and how we plan to address them.
