20. A system for collaborative note taking based on a speech by a speaker and providing a summary to a user in an audience of the speaker, the system comprising: a memory; an input/output circuit for: receiving a set of information from the speech; retrieving portions of information from the set of information; and retrieving portions of context information from a presentation information source to obtain domain information, the portions of information from the speech being temporally associated with the portions of context information from the presentation information source; a processor that performs the operations: determines at least one language model based on the portions of information from the speech and the temporally associated portion of context information from the presentation information source, wherein the at least one language model is dynamically determined; applies the language model to the set of information to extract salient tokens from the set of information; generates the summary; transmits the summary to be displayed to the user; and adjusts the language model according to the user feedback after receiving collaborative user feedback information relating to the summary; and a relevance and correctness determination circuit for verifying relevance of the salient tokens based on support information to obtain verified tokens, wherein the summary is generated by assembling the verified tokens.
