Abstract

The low effectiveness of most current information systems has often been pointed out and deplored. A number of misconceptions and experiments under unrealistic conditions have contributed to the faulty design and evaluation of information systems. The postulate of representational predictibility can help to clarify some of the still pending issues as there are the strenghts and limitations of uncontrolled natural language text in retrieval systems, factors for their evaluation, the reliability, consistency, and exhaustivity of indexing, the postulated 'inverse precision-recall relationship', and the usefulness of syntactical evices. The performance of information systems can be imporved if representational predictibility is aimed at in their design and operational use
