Multilingual Entity-Centered Sentiment Analysis Evaluated by Parallel Corpora

We propose the creation and use of a multilingualparallel news corpus annotatedwith opinion towards entities, produced byprojecting sentiment annotation from onelanguage to several others. The objectiveis to save annotation time for developmentand evaluation purposes, and to guaranteecomparability of opinion mining evaluationresults across languages. By creatingthis resource, we answered the questionwhether sentiment is consistently translatedacross languages so that projectioncan actually be an option. We describe ourapproach to multilingual sentiment analysisand show its performance in 7 languagesof the parallel corpus.
