A one-dimensional embedding complex

Published in Journal of Pure and Applied Algebra, 2002

Applications of parallel corpora to the development of monolingual language technologies

Published in N/A, 2005

We describe the development of an aligned parallel corpus of English and Irish texts, along with a simple application enabling the standardization of documents written in prestandard or dialect forms of Irish.

New perspectives on self-linking

Published in Advances in Mathematics, 2005

We initiate the study of classical knots through the homotopy class of the nth evaluation map of the knot, which is the induced map on the compactified n-point configuration space.

Machine translation for closely related language pairs

Published in Proceedings of the Workshop “Strategies for developing machine translation for minority languages” at LREC 2006, 2006

Managing Data from Social Media: The Indigenous Tweets Project

Published in The Open Handbook of Linguistic Data Management, 2022

This chapter is a case study in collecting and managing linguistic data from Twitter as part of the Indigenous Tweets project, which was founded in 2011 as a way of promoting the use of Indigenous and minority languages in social media. Our principal aim in this chapter is to describe our data management procedures in sufficient detail that linguists, sociolinguists, lexicographers, or community language activists with some programming skills can begin experimenting with Twitter data themselves.

NLP and AI in languages beyond English

Published:

Abstract: We all recognize the amazing success of language models in developing advanced AI/NLP technologies like ChatGPT for English. But very few other languages have access to the billions of words of text needed to train high-quality LLMs; this is what I call “the new digital divide”. I’d like to talk in broad terms about the prospects in terms of AI and NLP for the other 7000 or so languages spoken in the world today.
