By adopting this approach, users can find the traveling similarity with
other tourists in the management server. The procedure of finding the most
similar user is a little inefficient since the records of every two users need
to be compared once. The number of repeated locations of two users can
not indicate the traveling similarity of them because the total visited loca-
tions should also be considered in the similarity evaluation. The numbers
of repeated scenes will be divided by the number of total scenes visited by
tourists. The final results will present the degree of the similarity between
users' travel records. With adequate presentation like ranks, users will find
similar tourists and can access locations they visited.
There are several services provided by this server. Figure 13.4 shows sev-
eral components of the management server. The three components in the
upper side of this server are the login manager, the travel topics manager,
and the resources pool. All of them can be considered as front services of this
server. The agent program runs on the server, there is no direct interfaces
for users to operate it. The travel topics manager and the resources pool are
interfaces for users to edit travel notes and access multimedia resources in
the server. The other three components are on the lower side of Figure 13.4:
the Web page server, the database, and the usage history analyzer. All of
these components provide services for storing and analyzing information
from users.
