Abstract

Identifying the character entities correctly in a story becomes extremely challenging since an entity can refer to a proper noun, a phrase, or a particular definition. This study proposes BPSO-CRF, a hybrid NER method to extract character entities in Balinese stories. In addition, we develop a training dataset for balinese character named entities recognition task. We compare the proposed method against three baseline methods. Overall, BPSO-CRF obtains a relatively better recognition rate compared to the baseline method. Furthermore, only a few numbers of contextual features are relevant to improve the performance of the baseline CRF model.
