Learning Sentiment-Specific Word Embedding via Global Sentiment Representation

Peng Fu, Zheng Lin, Fengcheng Yuan, Weiping Wang, Dan Meng
We take global sentiment representation as a simple average of word embeddings in the text, and use a corruption strategy as a sentiment-dependent regularization.  ...  Recently, some sentiment embedding learning methods have been proposed, but most of them are designed to work well on sentence-level texts.  ...  The authors would like to thank the anonymous reviewers and the area chairs for their constructive comments.  ...

Robust Gram Embeddings

Taygun Kekec, David M. J. Tax
2016 Proceedings of the 2016 Conference on Empirical Methods in Natural Language Processing  
We propose a regularized embedding formulation, called Robust Gram (RG), which penalizes overfitting by suppressing the disparity between target and context embeddings.  ...  Our experimental analysis shows that the RG model trained on small datasets generalizes better compared to alternatives, is more robust to variations in the training set, and correlates well to human similarities  ...  We also would like to thank Hamdi Dibeklioglu and Mustafa Unel for their kind support during this work.  ...

2017 Telfor Journal  
In this paper, we assess the impact of lemmatizers and stemmers for Serbian on classifiers trained and evaluated on the Serbian Movie Review Dataset.  ...  An open issue in the sentiment classification of texts written in Serbian is the effect of different forms of morphological normalization and the usefulness of leveraging large amounts of unlabeled texts  ...  An additional drawback of lemmatizers for Serbian, in the context of sentiment analysis, is that they reduce all degrees of comparison of adverbs and adjectives into one.  ...
