A Comparative Evaluation of a New Unsupervised Sentence Boundary Detection Approach on Documents in English and Portuguese

Abstract. In this paper, we describe a new unsupervised sentence boun-dary detection system and present a comparative study evaluating its performance against different systems found in the literature that have been used to perform the task of automatic text segmentation into sen-tences for English and Portuguese documents. The results achieved by this new approach were as good as those of the previous systems, es-pecially considering that the method does not require any additional training resources.
