11. One or more non-transitory computer-readable storage media having computer-executable instructions embodied thereon, wherein when executed by at least one of processor, the computer-executable instructions cause the processor to: receive a plurality of user feedback items and a plurality of support solutions to the user feedback items; identify associations between the user plurality of user feedback items and the plurality of support solutions, including: filtering the plurality of user feedback items using a domain-specific dictionary of terms that is derived from documents corresponding to the plurality of support solutions; and assign a term frequency-inverse document frequency (TF-IDF) score to each of the filtered user feedback items; generate, based on the TF-IDF scores, a mapping of a given phrase from the filtered user feedback items to one or more support solutions from the plurality of support solutions; and generate an items-solutions model using the mapping of the given phrase to the one or more support solutions; and when the processor receives a new instance of user feedback: automatically determine, using the items-solutions model and based on a phrase included in the user feedback, one or more support solution responses to the new instance of user feedback; and output the one or more determined support solution responses to a user.

The computer-readable storage media of claim 11 , wherein the computer-executable instructions further cause the processor to identify groups of related user feedback items that share a support solution.
