NAACL HLT 2007 Workshop: Confidence Estimation for Natural Language Processing Confidence estimation (CE) is a method for automatically estimating the reliability of output generated by NLP systems. It is useful in scenarios where the underlying systems make errors, especially when human users are involved. This is the case in many areas of NLP, because systems are known to be imperfect. Applications can exploit knowledge of likely mistakes to improve their interactions with users and thereby enhance their overall effectiveness. The workshop aims at bringing researchers from different NLP fields together. We would like to provide a forum for sharing ideas, techniques, and experience on common aspects of CE across different areas of NLP. We hope to provide an opportunity for researchers to learn from previous and ongoing work in other fields.
