The method utilises a formula from communication theory due to Shannon and Weaver which describes the uncertainty H(p\,p2,...pn) in outcome of an event which is the result of a Markov process where the individual events have probabilities of occurrence Pi,p2,-Pn- A taxonomy of basic windows operations is developed for Microsoft Windows and used to show that a windows dialogue can also be described as a Markov process.	cache/ajis02-402.pdf	txt/ajis02-402.txt
