Temporal reasoning in medicine with an example in cystic fibrosis patient management-artificial intelligence mini-tutorial. 2

Abstract

For pt.1 see ibid., p.33-42. A brief history of temporal reasoning in medical applications is given. An expert system called Monitor is described that can perform the following tasks: the incremental evaluation of the data; retrieval of historical data for comparison purposes; determination of the validity of the data cross references over time; assessment of the disease progression by abstracting trends and changes from the time-ordered data; and extraction of duration information from the symptom data. An initial evaluation of Monitor using 111 cases has shown that the system can classify 88% of the cases correctly.<>
