N2 - In this paper we evaluate the performance of hybrid access methods for efficient information retrieval. For this, we establish a taxonomy of access methods using signature files; i.e. bit-sliced signature file method (BSM), hybrid method (HM), two-level signature file method (TSM), and two-level hybrid method (THM). We show from experimental results that two hybrid methods outperform BSM and TSM on retrieval. Among the hybrid methods, HM is the best method on retrieval in a small database with 20,000 records whereas THM outperforms HM when the number of matching records are small (less than 60) in a medium database with 100,000 records.
