Opinion 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 کاملDomain Adaptation for Opinion Mining: A Study of Multipolarity Words
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. W...
متن کاملOpinion Mining, Social Networks, Higher Education
Background and Aim: With the advent of technology and the use of social networks such as Instagram, Facebook, blogs, forums, and many other platforms, interactions of learners with one another and their lecturers have become progressively relaxed. This has led to the accumulation of large quantities of data and information about studentschr('39') attitudes, learning experiences, opinions, and f...
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...
متن کاملAutomatic Domain Ontology Extraction for Context-Sensitive Opinion Mining
Automated analysis of the sentiments presented in online consumer feedbacks can facilitate both organizations’ business strategy development and individual consumers’ comparison shopping. Nevertheless, existing opinion mining methods either adopt a context-free sentiment classification approach or rely on a large number of manually annotated training examples to perform contextsensitive sentime...
