11. A system for predicting user behaviors based on term taxonomies, comprising: a processing unit; and a memory, the memory containing instructions that, when executed by the processing unit, configure the system to: generate phrases respective of user generated content, wherein each phrase is a sentiment phrase or a non-sentiment phrase, each sentiment phrase including at least one word describing a sentiment; identify at least one connection between at least two of the generated phrases, wherein each connection is a direct connection or a hidden connection; generate at least one term taxonomy based on the identified at least one connection, wherein each term taxonomy is an association between a non-sentiment phrase and at least one of a plurality of sentiment phrases; periodically analyze the at least one term taxonomy to determine at least one trend of each non-sentiment phrase respective of the associated plurality of sentiment phrases; and generate a prediction of future behavior of the at least one trend with respect to the at least one term taxonomy.
