Sinossi

Quotation Extraction consists of identifying quotations from a text and associating them to their authors. In this work, we present a Quotation Extraction system for Portuguese. Quotation Extraction has been previously approached using different techniques and for several languages. Our proposal differs from previous work since we use Machine Learning to automatically build specialized rules instead of human-derived rules. Machine Learning models usually present stronger generalization power compared to human-derived models. In addition, we are able to easily adapt our model to other languages, needing only a list of verbs of speech for a given language. The previously proposed systems would probably need a rule set adaptation to correctly classify the quotations, which would be time consuming. We tackle the Quotation Extraction task using one model for the Entropy Guided Transformation Learning algorithm and another one for the Structured Perceptron algorithm. In order to train and evaluate the system, we have build the GloboQuotes corpus, with news extracted from the globo.com portal.
