The Open Multilingual Online Lexicon of Okinawan (OMOLO) project aims to create an accessible, user-friendly digital lexicon for the endangered Okinawan language using digital humanities tools and methodologies. The multilingual web application, available in Japanese, English, Portuguese, and Spanish, will benefit language learners, researchers, and the Okinawan community in Japan and diaspora countries such as the U.S., Brazil, and Peru. The project also lays the foundation for an Okinawan UD Treebank, which will support computational analysis and the development of language technology tools such as parsers, machine translation systems, and speech recognition software. The OMOLO project demonstrates the potential of computational linguistics in preserving and revitalizing endangered languages and can serve as a blueprint for similar initiatives.

With the increasing availability of wordnets for ancient languages, such as Ancient Greek and Latin, gaps remain in the coverage of less studied languages of antiquity. This paper reports on the construction and evaluation of a new wordnet for Coptic, the language of Late Roman, Byzantine and Early Islamic Egypt in the first millenium CE. We present our approach to constructing the wordnet which uses multilingual Coptic dictionaries and wordnets for five different languages. We further discuss the results of this effort and outline our on-going/future work.
