Current controlled medical terminologies fall short of the needs of informatics application developers. To overcome the limitations of current medical terminologies, many groups are independently enhancing existing terminologies to meet their local needs. With proper computer-based support, local enhancements can be used as evolutionary stepping stones(More)
As the size and complexity of medical terminologies increase, terminology modelers are increasingly hampered by lack of tools and methods to manage the development process. This paper presents our use and ongoing evaluation of a description-logic classifier to support cognitive scalability of the underlying terminology and our enhancements to that(More)
BACKGROUND Randomized clinical trial (RCT) results are often difficult to find, interpret, or apply to clinical care. The authors propose that RCTs be reported into electronic knowledge bases-trial banks-in addition to being reported in text. What information should these trial-bank reports contain? METHODS Using the competency decomposition method, the(More)
Clinical trials constitute one of the main sources of medical knowledge, yet trial reports are difficult to find, read, and apply to clinical care. Reasons for these difficulties include the lack of a common, standardized, structure for trial reports; the restricted length of reports; and limited computer support for use of the literature. We propose a new(More)
This paper explores a model of choice and explanation in medical management and makes clear its advantages and limitations. The model is based on multiattribute decision making (MADM) and consists of four distinct strategies for choice and explanation, plus combinations of these four. Each strategy is a restricted form of the general MADM approach, and each(More)
There has been little or no integration of specific studies from the clinical literature with computer-based medical advice systems. This paper reports preliminary results of a research project designed to model reasoning from the clinical literature. The program, named "Roundsman", draws upon structured representations of the clinical literature in order(More)
refined in an iterative, incremental fashion. Even when a satisfactory draft evolves, an author frequently makes minor changes on each reading of the paper, particularly if the author sets the manuscript aside between readings. Compared to the manual process of writing a paper, the process of creating a computer program to generate prose can be even more(More)
