Potential and Limitations of Cross-Domain Sentiment Classification

摘要

In this paper we investigate the cross-domain performance of sentiment analysis systems. For this purpose we train a con-volutional neural network (CNN) on data from different domains and evaluate its performance on other domains. Furthermore, we evaluate the usefulness of combining a large amount of different smaller annotated corpora to a large corpus. Our results show that more sophisticated approaches are required to train a system that works equally well on various domains.
