Abstract
Sentiment detection has gained relevance in the last years
due to the vast amount of publicly available opinion in the form of Web
forums or blogs. Yet, it still suffers from the ambiguity of language,
lowering the efficacy and accuracy of sentiment detection systems. Thus,
it is important to also invoke context information to refine the initial
values of sentiment terms. Moreover, domain-independence is desirable
to avoid using a topic determination beforehand. This work investigates
strategies for extracting non-generic features to be integrated into a so called
contextualized sentiment lexicon, capable of getting the context
correctly and assigning sentiment terms the proper sentiment value. The
proposed approach will be applied in an online-media aggregation and
visualization portal, covering a vast number of news media sources.
