Abstract

The probabilistic theory of information retrieval involves the construction of mathematical models based on statistical assumptions of various sorts. One of the hazards inherent in this kind of theory construction is that the assumptions laid down may be inconsistent with the data to which they are applied. Another hazard is that the stated assumptions may not be the real assumptions on which the derived modelling equations or resulting experiments are actually based. Both kinds of error have been made repeatedly in research on probabilistic information retrieval. One consequence of these lapses is that the statistical character of certain probabilistic IR models, including the so-called 'binary independence' model, has been seriously misapprehended.
