Domain Adaptation for Opinion Mining: A Study of Multipolarity Words
نویسندگان
چکیده
Expression of opinion depends on the domain. For instance, some words, called here multi-polarity words, have different polarities across domain. Therefore, a classifier trained on one domain and tested on another one will not perform well without adaptation. This article presents a study of the influence of these multi-polarity words on domain adaptation for automatic opinion classification. We also suggest an exploratory method for detecting them without using any label in the target domain. We show as well how these multi-polarity words can improve opinion classification in an open-domain corpus.

Résumé. Les méthodes de détection automatique de l’opinion dans des textes s’appuient sur l’association d’une polarité d’opinion aux mots des textes, par lexique ou par apprentissage. Or, certains mots ont des polarités qui peuvent varier selon le domaine thématique du texte. Nous proposons dans cet article une étude des mots ou groupes de mots marqueurs d’opinion au niveau du texte et qui ont ...

متن کاملOpinion Mining by Transformation-Based Domain Adaptation
Here we propose a novel approach for the task of domain adaptation for Natural Language Processing. Our approach captures relations between the source and target domains by applying a model transformation mechanism which can be learnt by using labeled data of limited size taken from the target domain. Experimental results on several Opinion Mining datasets show that our approach significantly o...
متن کاملEvaluation of different strategies for domain adaptation in opinion mining
The work presented in this article takes place in the field of opinion mining and aims more particularly at finding the polarity of a text by relying on machine learning methods. In this context, it focuses on studying various strategies for adapting a statistical classifier to a new domain when training data only exist for one or several other domains. This study shows more precisely that a se...
