Where did it all go wrong? New Tools for Automatic Error Analysis in NLP
- đ¤ Speaker: Jonathan Kummerfeld

Abstract
System performance is typically interpreted through metrics, which quantify errors, but do not analyse them. In this talk I will present new tools that automatically analyse system output, giving a linguistically intuitive breakdown of errors.
For parsing I will present results for English and Chinese, showing how error distributions vary between systems, what types of errors are being resolved by re-rankers, and what types are introduced when parsing out-of-domain text. For co-reference resolution I will present some preliminary results, comparing the errors made by systems in a recent shared task.
Jonathan is a PhD candidate at the University of California, Berkeley, advised by Dan Klein
