Abstract: A data mining system extracts job opening information and derives, for a given job, relevant competencies and derives, for a given candidate, relevant competencies, for the candidate. In some embodiments, the data mining performs authentication of relevant competencies before performing matching. The matching outputs can be used to provide data to a candidate indicating possible future competencies to obtain, to provide data to a teaching organization indicating possible future competencies to cover in their coursework, and to provide data to employers related to what those teaching organizations are covering.
