Abstract

The SMART System and Okapi System are two distinguished information retrieval (IR) systems. The former uses a vector space model and the latter uses a probabilistic retrieval strategy. A lot of previous research on information retrieval was carried out on these two systems, which showed that both were effective in IR. In this paper, we carry out a series of experiments on TREC-9 collections to discuss the different performance between these two kinds of retrieval systems in Chinese information retrieval. Our experimental results show that the performance of the Okapi System is better than that of the SMART System.
