Information retrieval based on stored program electronic computers has been an active area of research since the time these machines were invented. It is therefore somewhat surprising that even now no formal computational model for IR exists. There is no well-defined logic to describe information retrieval, and there is no proof or model theory to talk about the truths of IR.
This paper argues that much of the research… CONTINUE READING
