  We have developed an application that will take a "MEDLINE" output from the
PubMed database and allows the user to cluster all non-trivial words of the
abstracts of the PubMed output. The number of clusters to use can be selected
by the user.
  A specific cluster may be selected, and the PMIDs and dates for all
publications in the selected cluster are displayed underneath. See figure 2,
where cluster 12 is selected.
  The application also has an "Abstracts" tab, where the abstracts for the
selected cluster can be perused. Here, it is also possible to download a HTML
file containing the PMID, date, title, and abstract for each publication in the
selected cluster.
  A third tab is called "Titles", where all the titles for the selected cluster
are displayed.
  Via a "Use Cluster" button, the selected Cluster can itself be clustered. A
"Back" button allows the user to return to any previous state.
  Finally, it is also possible to exclude documents whose abstracts contain
certain words (see figure 3).
  The application will allow researchers to enter general search terms in the
PubMed search engine, then use the application to search for publications of
special interest within those search terms.
