Thank you guys for your prompt answers. I'm a beginner with Lucene and I still had some unclarities regarding its scoring function. Your answers really cleared things up for me. I guess a direct comparison with LSI is not possible after all, only the comparison between LSI and the pure VSM.
Thanks again, Sonia ____________________________________________________________________________________ Be a better pen pal. Text or chat with friends inside Yahoo! Mail. See how. http://overview.mail.yahoo.com/
