Combining Sample Selection and Error-Driven Pruning for Machine Learning of Coreference Rules

Authors: nan

Publication: TIPSTER (2002)

DOI: nan

Most machine learning solutions to noun phrase coreference resolution recast the problem as a classification task. We ex- amine three potential problems with this reformulation, namely, skewed class dis- tributions, …...

Named Entity Recognition: A Maximum Entropy Approach Using Global Information

Authors: nan

Publication: TIPSTER (2002)

DOI: nan

This paper presents a maximum entropy-based named entity recognizer (NER). It differs from pre- vious machine learning-based NERs in that it uses information from the whole document to classify each …...

Coreference Resolution Using Competition Learning Approach

Authors: nan

Publication: TIPSTER (2003)

DOI: nan

In this paper we propose a competition learning approach to coreference resolu- tion. Traditionally, supervised machine learning approaches adopt the single- candidate model. Nevertheless the prefer- ence relationship between the …...
