ABSTRACT
In this work, we assess objectivity in online news media. We propose to use topic independent features and we show in a cross-domain experiment that with standard bag-of-word models, classifiers implicitly learn topics. Our experiments revealed that our methodology can be applied across different topics with consistent classification performance.

Improved classification with allocation method and multiple classifiers
We propose a new allocation method for building a classification ensemble.Allocation method uses multiple classifiers: the allocator and micro classifiers.Allocator separates the dataset and allocates them to one of micro classifiers.Allocator is based ...
Hierarchical classification in text mining for sentiment analysis of online news
Sentiment analysis in text mining is a challenging task. Sentiment is subtly reflected by the tone and affective content of a writer's words. Conventional text mining techniques, which are based on keyword frequencies, usually run short of accurately ...
A boosted SVM based sentiment analysis approach for online opinionated text
RACS '13: Proceedings of the 2013 Research in Adaptive and Convergent SystemsThe opinionated text available on the Internet and Web 2.0 social media has created ample research opportunities related to mining and analyzing public sentiments. At the same time, the large volume of such data poses severe data processing and ...
