Topic By Topic Performance of Information Retrieval Systems

Abstract
Formulation of topic properties is the goal of this paper. These properties are to be used in judging the difficulty of topics appropriate to the Text REtrieval Conference (TREC) ad hoc task. Applying statistical methods to both TREC-6 and TREC-7 information retrieval results, we identify topic pairs that exemplify topic properties useful in relating topic statements to system performance. From two topics that seem the same with respect to the challenge they provide information retrieval systems, we formulate topic properties by relating the corresponsing topic statements to what is known about information retrieval systems. Some properties apparent in the topic pairs identified are linked to topicexpansion. These pairs exemplify both the need for expansion and the danger in automatic expansion.Citation
