The cultural component of the intended platform comprises textual data, images of artifacts and living entities (animals and plants in the area), as well as audio and video. The thesaurus covers the domains of Archaeology, Literature, Mythology, and Travel; therefore, it can be viewed as a set of inter-linked thesauri.

abstract = {Wordnets have been a popular lexical resource type for many years. Their sense-based representation of lexical items and numerous relation structures have been used for a variety of computational and linguistic applications. The inclusion of different wordnets into multilingual wordnet networks has further extended their use into the realm of cross-lingual research. Wordnets have been released for many spoken languages. Research has also been carried out into the creation of wordnets for several sign languages, but none have yet resulted in publicly available datasets. This article presents our own efforts towards an inclusion of sign languages in a multilingual wordnet, starting with Greek Sign Language (GSL) and German Sign Language (DGS). Based on differences in available language resources between GSL and DGS, we trial two workflows with different coverage priorities. We also explore how synergies between both workflows can be leveraged and how future work on additional sign languages could profit from building on existing sign language wordnet data. The results of our work are made publicly available.},

The project will produce a framework for intelligent machine translation to bring down language barriers among several spoken/written and sign languages. This paper describes the experience of the ILSP team to contribute to a multilingual repository of signs and their corresponding translations and to organize and enhance a bilingual dictionary (GSL – Modern Greek) as a result of this mapping; this will be the main focus of this paper. The methodology followed relies on the use of WordNet and, more specifically, the Open Multilingual WordNet (OMW) tool to map content in GSL to WordNet synsets.},

This infrastructure comprises a multi-lingual and multi-modal corpus (i.e., a corpus of textual data supplemented with images and video) that belongs to the humanities domain along with a dedicated database (content management system) with advanced indexing, linking, and search functionalities. We will present the corpus itself focusing on the content, the methodology adopted for its development, and the steps taken towards rendering it accessible via the database in a way that also facilitates useful visualizations. In this context, we tried to address three main challenges: (a) to add a novel annotation  layer, namely geotagging, (b) to ensure the long-term maintenance of and accessibility to the highly heterogeneous primary data – even after the life cycle of the current project – by adopting a metadata schema that is compatible to existing standards; and (c) to render the corpus a useful resource to scholarly research in the digital humanities by adding a minimum set of linguistic annotations.},
