Abstract

Conditional Random Fields (CRF) is a probabilistic method for structured prediction which has been widely applied in various areas such as Natural Language Processing (NLP), including the Named Entity Recognition (NER), computer vision, and bioinformatics. Therefore, this paper proposes to perform the task of applying the method CRF NER and an evaluation of its performance based on the corpus of HAREM. In summary, the system NERP-CRF achieved the best Precision results when compared to the systems evaluated in the same corpus, proving to be a competitive and effective system.
