Different Approaches to Automatic Polarity Annotation at Synset Level
E. Maks, Piek T. J. M. Vossen · VU Research Portal · 2011
In this paper we explore two approaches for the automatic annotation of polarity (positive, negative and neutral) of adjective synsets in Dutch. Both approaches focus on the creation of a Dutch polarity lexicon at word sense level using wordnet as a lexical resource. The first method is based upon the simple transfer of an English sentiment lexicon (Sentiwordnet 1.0) into Dutch. The second approach regards the use of a wordnet based propagation algorithm with different settings with respect to the quality and length of the seed lists. Results are validated against manually compiled gold standards and compared with results of similar approaches generating polarity lexicons for English.
