A system, method and program product for categorizing, analyzing, and continually aggregating unstructured communication data in the form of a query and responses. The method initially categorizes the conversation thread as a query and then uses natural language understanding technologies to start analyzing and extracting entities, sentiment and keywords. It then categorizes and aggregates those responses accordingly, providing the user with a continuously updated summary. The method groups the responses into Positive/Affirmative and Negative. The system can also determine conversations that need further action or response from the organizer by categorizing more complex individual responses that contain questions or action items. The method further analyzes an e-mail thread to identify a certain type of conversation, e.g., an RSVP/Poll, collect multiple responses, analyze the responses and tally up the results to create a summary that may be communicated back to the group thread originator according to a preferred messaging modality.
