Every day, information on the Web becomes increasingly
enriched. Web access is now very useful in many aspects of
daily life, particularly for writing documents and programs.
In fact, it has become quite usual to edit files while referring
to information on the Web. During the file-editing process,
we usually visit so many Web pages that we cannot remember
all of the relevant ones. Later, if we want to revisit the
same Web pages to modify some part of a file, it can be very
hard to track down the Web pages originally referred to.
In this paper, we propose methods for finding relationships
between files and Web pages based on the co-occurrence of
data in Web-access logs and file-access logs. These relationships
are very useful for revisiting Web pages related to
target files. To analyze co-occurrence in these two types of
access logs, there are two approaches for merging the logs,
involving a trade-off between accuracy and execution time.
We call them the Pre-Merge and Post-Merge methods, and
we have evaluated these two methods using actual access
logs.
