LX-Sentence Splitter

LX-Sentence Splitter is a language processing tool for delimiting sentences in Portuguese. It was developed and is maintained by the NLX-Natural Language and Speech Group at the University of Lisbon, Department of Informatics.

LX-Sentence Splitter marks sentence boundaries with <s>…</s>, and paragraph boundaries with <p>…</p>. It also unwraps sentences split over different lines. A f-score of 99.94% was obtained when testing on a 12,000 sentence corpus accurately hand tagged with respect to sentence and paragraph boundaries.
