The survey of research in the field of Named Entity Recognition and Classification (NERC) features, techniques and evaluation methods, is presented, though it is not extensive and may not cover all the languages. It gives the depth of previous work in the field. Automatic named entity recognition and classification in the text surely improves the quality of results while searching the web. Highly accurate Named Entity Recognition (NER) is a challenge even today. The output of NER system is used for question answering, document clustering, document summarization [9].
