Design Challenges and Misconceptions in Named Entity Recognition

  title={Design Challenges and Misconceptions in Named Entity Recognition},
  author={Lev-Arie Ratinov and Dan Roth},
We analyze some of the fundamental design challenges and misconceptions that underlie the development of an efficient and robust NER system. In particular, we address issues such as the representation of text chunks, the inference approach needed to combine local NER decisions, the sources of prior knowledge and how to use them within an NER system. In the process of comparing several solutions to these challenges we reach some surprising conclusions, as well as develop an NER system that… CONTINUE READING
