The WKWSCI Sentiment Lexicon

The WKWSCI Sentiment Lexicon by Christopher S. G. Khoo, Sathik Basha Johnkhan and Jin-Cheon Na is based on the 6of12dict lexicon, and currently covers adjectives, adverbs and verbs. The words were manually coded with a value on a 7-point sentiment strength scale. The effectiveness of the four sentiment lexicons for sentiment categorization at the document-level and sentence-level was evaluated using an Amazon product review dataset. The WKWSCI lexicon obtained the best results for document-level sentiment categorization, with an accuracy of 75%. The Hu & Liu lexicon obtained the best results for sentence-level sentiment categorization, with an accuracy of 77%.
