Expertness from Structured Text? Reconsider: A Diagnostic Prompting Program,
Abstract
Reconsider is an interactive diagnostic prompting which uses simple information retrieval techniques to prompt a physician regarding possible diagnoses, given a list of positive patient findings. Its knowledge base consists of 'structured text' definitions of 3262 diseases and a synonym dictionary. Patient findings, and their synonyms, are matched against inverted files of terms from the disease descriptions, the number and selectivity of the patient findings matching terms in a given disease description determine that disease's 'score', and the matched diseases are sorted on this score to form a preliminary differential diagnosis. Definitions of diseases can be referenced for viewing by name, or by their position in a differential. While its first formal evaluation is not yet complete, the performance of RECONSIDER continues to exceed the expectations of user and designer alike.
