Educational Tools for Mapuzugun
Cristian Ahumada | Claudio Gutierrez | Antonios Anastasopoulos
Proceedings of the 17th Workshop on Innovative Use of NLP for Building Educational Applications (BEA 2022)

Mapuzugun is the language of the Mapuche people. Due to political and historical reasons, its number of speakers has decreased and the language has been excluded from the educational system in Chile and Argentina. For this reason, it is very important to support the revitalization of the Mapuzugun in all spaces and media of society. In this work we present a tool towards supporting educational activities of Mapuzugun, tailored to the characteristics of the language. The tool consists of three parts: design and development of an orthography detector and converter; a morphological analyzer; and an informal translator. We also present a case study with Mapuzugun students showing promising results.

Dictionaries as Networks: Identifying the graph structure of Ogden’s Basic English
Camilo Garrido | Claudio Gutierrez
Proceedings of COLING 2016, the 26th International Conference on Computational Linguistics: Technical Papers

We study the network structure underlying dictionaries. We systematize the properties of such networks and show their relevance for linguistics. As case of study, we apply this technique to identify the graph structure of Ogden’s Basic English. We show that it constitutes a strong core of the English language network and that classic centrality measures fail to capture this set of words.
