    • An Intelligent Chat Channel Processor (ICCP) 410 for chat channel communications is configured to receive a user message and classify the message into one of a question, an answer, and a statement. When the input is a question, the ICCP determines a set of relevant answers from a database that are related to the question. The ICCP determines a relatedness score reflecting a degree of relatedness between each related answer of the set and the question. A top answer is determined from the set of related answers based on the relatedness scores, and the ICCP presents at least one of the top answer and the set of related answers to the user. When the input is an answer, the ICCP stores the answer in the database, and when the input is classified as a statement, it is discarded. The ICCP receives a feedback user message that rates the top answer and modifies a reward score for it to adjust a future top answer response. The set of relevant answers may be determined using a term frequency-inverse document frequency (TF-IDF). The classifier may use a recursive neural network. The top answer may be determined using a reinforcement learning agent.
