Abstract - Natural Language Processing ||
Multilingual Subjectivity Analysis University of North Texas
There is growing interest in the automatic extraction of opinions, emotions, and sentiments in text (subjectivity), to provide tools and support for various natural language processing applications. Most of the research to date has focused on English, which is mainly explained by the availability of resources for subjectivity analysis, such as lexicons and manually labeled corpora. In this talk, I will describe methods to automatically generate resources for subjectivity analysis for a new target language by leveraging on the resources and tools available for English, which in many cases took years of work to complete. Specifically, I will try to provide answers to the following questions. First, can we derive a subjectivity lexicon for a new language using an existing English lexicon and a bilingual dictionary? Second, can we derive subjectivity-annotated corpora in a new language using existing subjectivity analysis tools for English and parallel corpora? Finally, third, can we build tools for subjectivity analysis for a new target language by relying on these automatically generated resources?
