PhD Research School in Linguistics and Philology

Multilingual Lexical Resourses and Tools

The course will give a theoretical overview of lexical relations related to computational lexicons, wordnets and thesauri and will present different methods for their construction and exploitation.

Main content

The researcher training course on Multilingual Lexical Resources and Tools is a cooperation between CLARA, the Norwegian Research School on Linguistics and Philology and its local branch, the University of Bergen Research School on Linguistics and Philology.

In recent years, mono- and multilingual lexicons, wordnets and other lexical resources have become more readily available. In such databases, the information provided on words and their relations, both within and across languages, has become richer and more easily exploitable in various applications.

WordNets are being used in word sence disambiguation, machine translation, information extraction and information retrieval. Over 60 wordnets have been developed over the world. Typologically different languages have faced challenges in adapting the original model and linking wordnets across languages. Parallel corpora aligned at word level have created possibilities for analyzing translational correspondences and deriving lexical relations within and across languages by means of new computational methods (such as Semantic Mirrors). Furthermore, unstructured texts, such as ordinary web materials, can be mined in different ways by tools such as SketchEngine in order to fully automatically derive overviews of how lexical items behave in context.
