Paper Abstract

Intra- and inter-observer variability in the perception of radiographic findings by radiologists and the resulting uncertainty in the presence or absence of these findings complicates the process of verifying the accuracy of expert systems that use this data. To validate these expert systems, techniques must be developed to obtain a "true" set of findings for each case in the database. Several techniques are presented for obtaining these data sets. These methods may have utility in other domains where the input to an expert system consists of features which have significant variability in perception.
