The.WASP.Model
We propose a unified framework that is founded on four building blocks which, in our
point of view, will be absolute necessities to populate the future Web with more powerful
applications:
??? Web Services as a means of providing a unified communication interfaces between
applications and agencies (Christensen et al., 2001; Dale, 2002; UDDI, 2001);
??? Agents as a natural and central means to represent typical tasks and solutions for a
distributed and constantly changing information environment;
??? Semantic Web technologies as a means to provide data and information in a consistent
manner that allows retrieval and reasoning; and
??? Personalization technologies to customize processes to the needs of the individual
user, an absolute necessary concerning the current (and future) size of the World Wide
Web, lest it becomes impossible to separate useless from useful information.
(The initials of these core technologies also provide the acronym for our framework:
WASP)
Agents will be the central building block of this architecture, because they implement the
actual business logic. Web Services are the natural means of communication and collaboration
for agents working under the described model; the Semantic Web is the environment
(world) for these agents, and the personalization rules basically can be used to make up or
modify the beliefs of the agents.
