A method (and system) of determining a knowledge gap between a first database containing a set of problems records and a second database containing solutions documents, includes developing a set of clusters of the problems records of the first database, where each cluster has a centroid, developing a dictionary having entries based on the problems records in the first database, developing a vector space correlated to the solutions documents in the second database, where the vector space is based on the dictionary entries, developing a listing of distances between the cluster centroids and the vector space, and determining a knowledge gap for each cluster.
