Rothenberg, Douglas H.
An efficiency model and a performance function are presented in this technical report. The efficiency model has been tailored to the needs of an information retrieval system while remaining consistent with established economic procedures. The performance function allows for the comparison of several information retrieval systems. A sample performance function is given and its characteristics discussed; optimal properties of function are also advanced and an illustration presented. (Author)
