  <dc:description xmlns:ns0="xml" ns0:lang="en">Although retrieval systems based on probabilistic models will rank the  objects (e.g. documents) being retrieved according to the probability of  some matching criterion (e.g. relevance) they rarely yield an actual  probability and the scoring function is interpreted to be purely ordinal  within a given retrieval task. In this paper it is shown that some scoring  functions possess the likelihood property, which means that the scoring  function indicates the likelihood of matching when compared to other  retrieval tasks which is potentially more useful than pure tanking  although it cannot be interpreted as an actual probability. This property  can be detected by using two modified effectiveness measure, entire  precision and entire recall. Empirical evidence is offered to show the  existence of this property both for traditional document retrieval and for  analysis of crime data where suspects of an unsolved crime are ranked  according to probability of culpability.</dc:description>
