Improving Machine Learning Approaches to Coreference Resolution

چکیده
We present a noun phrase coreference system that extends the work of Soon et al. (2001) and, to our knowledge, produces the best results to date on the MUC6 and MUC-7 coreference resolution data sets — F-measures of 70.4 and 63.4, respectively. Improvements arise from two sources: extra-linguistic changes to the learning framework and a large-scale expansion of the feature set to include more sophisticated linguistic knowledge.

Corpus based coreference resolution for Farsi text
"Coreference resolution" or "finding all expressions that refer to the same entity" in a text, is one of the important requirements in natural language processing. Two words are coreference when both refer to a single entity in the text or the real world. So the main task of coreference resolution systems is to identify terms that refer to a unique entity.

متن کاملMachine Learning Approaches to Coreference Resolution
This paper introduces three machine learning approaches to noun phrase coreference resolution. The first of them gives a view of coreference resolution as a clustering task. The second one applies a noun phrase coreference system based on decision tree induction and the last one experiments with using the Bell tree to represent the search space of the coreference resolution problem. The knowled...
متن کاملLatent Structures for Coreference Resolution
Machine learning approaches to coreference resolution vary greatly in the modeling of the problem: while early approaches operated on the mention pair level, current research focuses on ranking architectures and antecedent trees. We propose a unified representation of different approaches to coreference resolution in terms of the structure they operate on. We represent several coreference resol...
