Technologies are disclosed for identifying converged conversation threads. A number of the most recent messages in a conversation thread are selected. Selected messages that are action messages or query messages are identified. Scores are then assigned to the action and query messages. A determination is then made as to whether the conversation thread is converged or non-converged based upon the scores. Data is then stored that indicates that the conversation thread is converged or non-converged. The stored data can be used to locate converged or non-converged threads and identify the threads in a UI as such.
