1. A method, in a data processing system comprising a processor and a memory, for performing an operation based on an identification of similar lines of questioning by input question sources, the method comprising: obtaining, by the data processing system, question information identifying extracted features of an input question and a first source of the input question; performing, by the data processing system, a clustering operation to cluster the input question with one or more other questions of a cluster based on a similarity of the extracted features of the input question to features of the one or more other questions; and performing, by the data processing system, an operation based on results of the clustering of the input question with the one or more other questions, wherein the operation facilitates at least one of a collaboration between the first source of the input question and a second source of another question in the cluster, a communication between the first source and the second source, or a reporting of the results of the clustering operation to either the first source, the second source, or a third party.
