This paper describes algorithms which rerank the top N hypotheses from a maximum-entropy tagger, the applica- tion being the recovery of named-entity boundaries in a corpus of web data. The …...

This paper presents comparative experimen- tal results on four techniques of language model adaptation, including a maximum a posteriori (MAP) method and three dis- criminative training methods, the boosting algorithm, …...

Lasso is a regularization method for pa- rameter estimation in linear models. It op- timizes the model parameters with respect to a loss function subject to model com- plexities. This …...

This paper proposes two techniques for fast sequential labeling such as part-of-speech (POS) tagging and text chunking. The first technique is a boosting-based al- gorithm that learns rules represented by …...

This paper proposes a boosting algorithm that uses a semi-Markov perceptron. The training algorithm repeats the training of a semi-Markov model and the update of the weights of training samples. …...

Research in text classification currently fo- cuses on challenging tasks such as sen- timent classification, modality identifica- tion, and so on. In these tasks, approaches that use a structural representation, …...

We present an approach to learning bilin- gual n-gram correspondences from relevance rankings of English documents for Japanese queries. We show that directly optimizing cross-lingual rankings rivals and complements machine …...

We address the problem of identifying mul- tiword expressions in a language, focus- ing on English phrasal verbs. Our poly- glot ranking approach integrates frequency statistics from translated corpora in …...
