In-Depth Information
together the databases of the Transpole, Semurval and SNCF operators. We have
simulated this authority by creating an XML database enabling the itinerary search
for a trip from Valenciennes to Lille. The user information is stored in the
Lightweight Directory Access Protocol
(LDAP) directory, which is the same one
that MASC uses for user management.

Use case diagram of the itinerary search service seen
from the perspective of personalization
By analyzing this use case diagram and following the rules of the PerMet
method for agent model analysis (see section 3.4.4), we obtain an agent model for
the itinerary search and an agent model for management of the user profile. Indeed,
rule 1 (an agent model of expected functionality of the service) and rule 3 (an agent
model by external resource), led us to an agent model for the itinerary search and for
the management of user information. Rule 2, which stipulates that one agent model
is needed per interaction platform, will not be applied here because in this
application the objective is to leave management of the interaction between the user
and service to the MASC platform. The user accesses the service via a Web
browser. The different roles that these agents must play are described in Figure 3.15.
