Abstract

In this paper, two algorithms are designed for finding maximal forward references from very large Web logs,longest sequences of Web pages visited by a user withoutrevisiting some previously visited page in the sequence, andtheir performance is comparatively analyzed. It is shownthat the two algorithms have linear (hence optimal) timecomplexity.
