9. A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform a method comprising: retrieving, from a data storage circuit, multiple label sets that contain labels that each classify data points in a corpus of data; generating a graph that includes a plurality of edges, each edge between two respective labels from different label sets of the multiple label sets; determining weights for the plurality of edges based upon a consistency between the data points classified by two labels connected by the edges; applying an algorithm that creates grouped labels from the multiple label sets and based upon the weights for the plurality of edges; and identifying data points from the corpus of data that represent conflicts within the grouped labels; transmitting an electronic message for presenting the grouped data points to entities for further classification; and generating a new label set based upon the grouped labels and further classification received from the entities.
15. The computer program product of claim 9 , wherein the graph is a complete multipartite graph with respect to the label sets.
