Abstract: Computer systems and methods generate a cluster chart for HR-related documents. A host computer data center comprises a database for electronically storing HR-related documents, a web server, and a programmable computer device. The programmable computer device is programmed to determine clusters of prevalent terms in a collection of HR-related documents in the database. The collection of HR-related documents from which the clusters are generated is identified based on search criteria submitted from a client computer device. The clusters of prevalent terms in the collection can be determined using a clustering algorithm employing algebraic transformations of a term-document matrix generated from the collection of HR-related documents. The programmable computer device is also programmed to assign each of the HR-related documents in the collection to one or more of the determined clusters, and to generate a chart graphically showing the clusters. Each cluster in the chart has a characteristic (e.g.
