Methods, systems and computer program products are provided. Methods for detecting helpful query responses include generating helpfulness terminology data corresponding to words, terms, phrases and/or symbols that correspond to an expression of helpfulness. A query based exchange including multiple messages is identified. The messages are analyzed using the helpfulness terminology data to detect a helpful message. The helpful message is associated with a source participant and a helpfulness value that corresponds to the source participant is modified. A value corresponding to the query based exchange indicating that the query based exchange was successful is stored.
