The Open Multilingual Wordnet (OMW) is an open source project that was launched with the goal to make it easy to use wordnets in multiple languages without having to pay expensive proprietary licensing costs.As OMW evolved, the interlingual indicator (ILI) 1 was used to allow semantically equivalent synsets in different languages to be linked to each other.OdeNet 2 is the German language wordnet which forms part of the OMW project.This paper analyses the shortcomings of the initial ILI classification in OdeNet and the consequent methods used to improve this classification.

The Princeton WordNet for the English language has been used worldwide in NLP projects for many years.With the OMW initiative, wordnets for different languages of the world are being linked via identifiers.The parallel development and linking allows new multilingual application perspectives.The development of a wordnet for the German language is also in this context.To save development time, existing resources were combined and recompiled.The result was then evaluated and improved.In a relatively short time a resource was created that can be used in projects and continuously improved and extended.

In this paper we describe our current work on representing a recently created German lexical semantics resource in OntoLex-Lemon and in conformance with Word-Net specifications.Besides presenting the representation effort, we show the utilization of OntoLex-Lemon to bridge from WordNet-like resources to full lexical descriptions and extend the coverage of WordNets to other types of lexical data, such as decomposition results, exemplified for German data, and inflectional phenomena, here outlined for English data.
