Named entity recognition using conditional random field for kannada language

Abstract

— Named Entity Recognition (NER) is a significant errand in Natural Language Processing (NLP) applications like Information Extraction, Question Answering and so on. In this paper, factual way to deal with perceive Kannada named substances like individual name, area name, association name, number, estimation and time is proposed. We have achieved higher accuracy in CRF approach than the in HMM approach. The accuracy of classification is more accurate in CRF approach due to flexibility of adding more features unlike joint probability alone as in HMM. In HMM it is not practical to represent multiple overlapping features and long term dependencies. CRF ++ Tool Kit is used for experimentation. The consequences of acknowledgment are empowering and the approach has the exactness around 86%.
