We describe a mechanism and an algorithm to support construction of a large complex conceptual lexicon from an existing alphabetical lexicon.

This paper presents a large-scale Greek morphological lexicon, developed by 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 included in a controlled language checker for Greek. The ...
