ExATO - High Quality Term Extraction for Portuguese and English

Abstract

This paper presents a novel version of ExATO, a term extractor originally designed to extract relevant terms from corpora in Portuguese. In this new version not only corpora in Portuguese can be handled, but also texts in English are accepted. This extension is likely to offer the same quality pattern already achieved for Portuguese. In this paper, we draw the analysis of results in parallel corpora with respect to the intrinsic differences between Portuguese and English languages, and also the environment of usage for ExATO for Portuguese and English corpora. A brief comparison of ExATO and other similar tool is presented to illustrate the higher quality of ExATO extraction from English corpora.
