Methods, systems, and techniques for generating sentiment data are provided. Example embodiments provide a Sentiment Thesaurus Framework (STF), which provides a sentiment vocabulary meeting a set of criteria and a sentiment thesaurus according to certain connectedness rules. In one embodiment, the STF provides the sentiment thesaurus by relating connected adjective word-senses to valid sentiment adjective word-senses. The degree of connectedness is limited to one shift in meaning from one adjective to another, which implies at most two non-satellite or axle adjectives between a valid sentiment and a related adjective word-sense.
