27. A computer-implemented method for facilitating the production of an online thesaurus used to generate sentiment data for online content, comprising: generating and storing in a computer memory a plurality of valid sentiment adjective word-senses in a vocabulary data repository by determining whether each adjective from a set of possible adjectives is a valid sentiment based at least upon evaluation of a set of rules that define valid sentiments; and for each generated valid sentiment adjective word-sense, determining a set of related adjectives that meets a plurality of connection rules that limit, for each related adjective in the set, a degree of distance in meaning between the related adjective and the valid sentiment adjective word-sense; and storing, in a thesaurus data structure in a computer memory, the set of related adjectives, along with indications of the plurality of connection rules that have been met, to correspond with the valid sentiment adjective word-sense, such that, responsive to an indication of one of the related adjectives, the valid sentiment adjective word-sense can be retrieved.
