{"DOI":"10.25592/uhhfdm.12676","abstract":"<p>The purpose of the inter-lingual index is to link the lexical resources from the different languages<br>\nof the project and make them machine-readable. The earlier deliverable D6.3 was the first<br>\nversion of this index. It included German Sign Language (DGS) and Greek Sign Language<br>\n(GSL). This deliverable is the second version of the index. It covers further core sign languages<br>\nof the project: British Sign Language (BSL), Sign Language of the Netherlands (NGT), French<br>\nSign Language (LSF) and Swiss-German Sign Language (DSGS). The next version will be<br>\ndeliverable 6.5 and will include languages beyond the project&rsquo;s core languages.<br>\nThe deliverable is the index itself. This report provides background information on wordnet<br>\nresearch, explains our method and choices, and presents the resulting dataset.<br>\nOur interlingual index uses the wordnet concept of synonym sets (synsets), which define con-<br>\ncepts by gathering signs and words that can represent the same meaning. This approach is<br>\nmore resistant to translation mistakes stemming from translation pairs being only valid for cer-<br>\ntain word/sign meanings. It also provides a new way to define sign types that does not rely on<br>\napproximate translations to a single spoken language word, the way glosses do. As a basis for<br>\nour index, we build on the synset inventory of Open Multilingual Wordnet (OMW).<br>\nWe use a three-step method: The first step is automatically matching candidate synsets to signs<br>\nusing the keywords and glosses associated with the sign. The second step is automatically<br>\nvalidating links that are most likely to be correct. The final step is manual validation of the<br>\nremaining links, prioritising the most useful signs.<br>\nThis work has resulted in a dataset of 7929 signs in 6 sign languages linked to 11806 synsets.<br>\nAdditionally, a web interface has been launched to make the index accessible for the general<br>\npublic.</p>","author":[{"family":"Bigeard, Sam"},{"family":"Schulder, Marc"},{"family":"Kopf, Maria"},{"family":"Hanke, Thomas"},{"family":"Vasilaki, Kiriaki"},{"family":"Vacalopoulou, Anna"},{"family":"Goulas, Theodor"},{"family":"Dimou, Athanasia-Lida"},{"family":"Fotinea, Stavroula-Evita"},{"family":"Efthimiou, Eleni"},{"family":"Fox, Neil"},{"family":"Crasborn, Onno"},{"family":"Westenberg, Lianne"},{"family":"Ebling, Sarah"},{"family":"Wawrinka, Laure"}],"id":"12676","issued":{"date-parts":[[2023,6,30]]},"language":"eng","title":"Interlingual Index for the EASIER Project's Core Sign Languages","type":"report","version":"1.0"}
