This research investigated the application of techniques successfully used in previous information retrieval research, to the more challenging area of medical informatics. It was performed on a biomedical document collection testbed, Z .CANCERLIT, provided by the National Cancer Institute NCI , which contains information on all types of cancer therapy.
