Jian‐Yun Nie, François Ste-Marie Paradis, Jean G. Vaucher · 1993
Users of a given information retrieval system may have different requirements at various times (sometimes emphasizing precision, sometimes recall), and the corpus may have different degree of emphasis regarding subjects.Therefore, a general purpose system should have parameters to allow adjustable performance.This article investigates the integration of several evaluation methods into a single system so that a user may choose an appropriate method or a combination of methods for his query evaluation.
