Papers
A model of inexact reasoning in medicine
TL;DR: In this paper, a quantification scheme is proposed to model the inexact reasoning processes of medical experts, which is essentially an approximation to conditional probability, but offers advantages over Bayesian analysis when they are utilized in a rule-based computer diagnostic system.
A simple algorithm for identifying negated findings and diseases in discharge summaries
TL;DR: It is concluded that with little implementation effort a simple regular expression algorithm for determining whether a finding or disease mentioned within narrative medical reports is present or absent can identify a large portion of the pertinent negatives from discharge summaries.

TL;DR: The models are distinguished more by the number of variables and parameters that they contain than by their error rates; these differences suggest which models may be the most amenable to future implementation as paper-based guidelines.
