Abstract

We present newly-produced comparable corpora of book reviews in English and Russian. The corpora are comparable in terms of domain, style and size. We are using them for cross-lingual experiments in document-level sentiment
classi�cation. Quantitative analyses of the corpora and
the language di�erences they exhibit highlight a number of issues that must be considered when developing systems for automatic sentiment classi�cation. We also present experiments with a sentiment classi�cation system applied to the corpora.
The results suggest that di�erences in the way that sentiment is expressed in the two languages lead to large di�erence in sentiment classi�cation accuracy.
