INFORMATION RETRIEVAL

2 Information retrieval distinction leads one to describe data retrieval as deterministic but information retrieval as probabilistic. Frequently Bayes' Theorem is invoked to carry out inferences in IR, but in DR probabilities do not enter into the processing. Another distinction can be made in terms of classifications that are likely to be useful.
