14. A computer system for generating a conversation model representative of a state of a conversation between a plurality of participants, comprising: a non-transitory computer readable storage medium storing executable computer program instructions comprising instructions for: retrieving conversation text associated with the conversation, the conversation associated with a conversation interface accessible to the plurality of participants and displayed by a hardware client device of each participant, the conversation interface displaying content associated with the conversation; identifying a plurality of conversation model components representative of the conversation within the conversation text, each conversation model component associated with a timestamp representative of a time within the conversation in which the conversation text associated with the conversation model component occurs; determining correlation scores between pairs of conversation model components, wherein a correlation score represents a measure of relatedness between a pair of model components; querying a document corpus with one or more identified conversation model components associated with timestamps that occurred within an interval of time temporally adjacent to a time of querying the document corpus to identify candidate components included within the document corpus that are associated with the one or more identified conversation model components, the identified candidate components comprising key phrases or entities; identifying extrapolated conversation model components based on the plurality of conversation model components and the determined correlation scores, each extrapolated conversation model component selected from the identified candidate components included within the document corpus; storing the plurality of conversation model components, the extrapolated conversation model components, and the correlation scores as a conversation model; retrieving additional content based at least in part on the extrapolated conversation model components; updating the conversation interface displayed by each hardware client device to additionally display the retrieved additional content; a processor for executing the computer program instructions.
