AB This paper describes a software tool that aids researchers in
   the study of agenda setting. Agenda setting theory claims that
   the mass media influences what the public thinks and talks
   about. The tool is used to cluster documents into topically
   coherent groupings that are to represent issues dominating
   press coverage. The documents are taken from the archives of
   online newspapers. In addition, the fool enables results to be
   visualised and displayed. Three methods were investigated for
   the purpose of clustering, of which the Group-Average-Linkage
   algorithm was chosen for the final testing. The choice of the
   clustering algorithm was predominantly made upon the quality of
   clusters produced Comparisons between the computer-based
   results and a method involving human readers revealed
   comparable findings and potential usefulness of the software.
