Predicative Adjectives: An Unsupervised Criterion to Extract Subjective Adjectives
Michael Wiegand, Josef Ruppenhofer and Dietrich Klakow
We examine predicative adjectives as an unsupervised criterion to extract
We do not only compare this criterion with a weakly supervised extraction
method but also with gradable adjectives, i.e. another highly subjective subset
of adjectives that can be extracted in an unsupervised fashion.
In order to prove the robustness of this extraction method, we will evaluate
the extraction with the help of two different state-of-the-art sentiment
lexicons (as a gold standard).
