Big Data Methods for Computational Linguistics
Résumé
Many tasks in computational linguistics traditionally rely on hand-crafted or curated resources like the-
sauri or word-sense-annotated corpora. The availability of big data, from the Web and other sources,
has changed this situation. Harnessing these assets requires scalable methods for data and text ana-
lytics. This paper gives an overview on our recent work that utilizes big data methods for enhancing
semantics-centric tasks dealing with natural language texts. We demonstrate a virtuous cycle in harvest-
ing knowledge from large data and text collections and leveraging this knowledge in order to improve
the annotation and interpretation of language in Web pages and social media. Specifically, we show how
to build large dictionaries of names and paraphrases for entities and relations, and how these help to
disambiguate entity mentions in texts.
