In this project note we describe our work to make better documentation for the Open Multilingual Wordnet (OMW), a platform integrating many open wordnets.This includes the documentation of the OMW website itself as well as of semantic relations used by the component wordnets.Some of this documentation work was done with the support of the Google Season of Docs.The OMW project page, which links both to the actual OMW server and the documentation has been moved to a new location: https://omwn.org.

This paper introduces Wn, a new Python library for working with wordnets.Unlike previous libraries, Wn is built from the beginning to accommodate multiple wordnets-for multiple languages or multiple versions of the same wordnet-while retaining the ability to query and traverse them independently.It is also able to download and incorporate wordnets published online.These features are made possible through Wn's adoption of standard formats and methods for interoperability, namely the WN-LMF schema (Vossen et al., 2013;Bond et al., 2020) and the Collaborative Interlingual Index (Bond et al., 2016).Wn is open-source, easily available, 1 and well-documented. 2

The Global Wordnet Formats have been introduced to enable wordnets to have a common representation that can be integrated through the Global WordNet Grid.As a result of their adoption, a number of shortcomings of the format were identified, and in this paper we describe the extensions to the formats that address these issues.These include: ordering of senses, dependencies between wordnets, pronunciation, syntactic modelling, relations, sense keys, metadata and RDF support.Furthermore, we provide some perspectives on how these changes help in the integration of wordnets.

In this paper we discuss the experience of bringing together over 40 different wordnets. We introduce some extensions to the GWA wordnet LMF format proposed in Vossen et al. (2016) and look at how this new information can be displayed. Notable extensions include: confidence, corpus frequency, orthographic variants, lexicalized and non-lexicalized synsets and lemmas, new parts of speech, and more. Many of these extensions already exist in multiple wordnets – the challenge was to find a compatible representation. To this end, we introduce a new version of the Open Multilingual Wordnet (Bond and Foster, 2013), that integrates a new set of tools that tests the extensions introduced by this new format, while also ensuring the integrity of the Collaborative Interlingual Index (CILI: Bond et al., 2016), avoiding the same new concept to be introduced through multiple projects.
