Abstract
Lexicon-based (or knowledge-based) approaches to sentiment analysis require a lexical resource referred to as sentiment or opinion lexicon for analysing the sentiment. The single words or phrases of a text can then be matched to the lexicon entries and the polarity can be assigned. The biggest challenge is to generate the lexicon. In this chapter, we briefly introduce various approaches to generate domain-specific sentiment lexicons.
