The Semantic Web paradigm will
change drastically the way the web is
used with
the attempt to achieve semantically rich, well-structured, standardized
and
verified content for various application areas. The current effort is
to enable
the machines to process meaning which can guide the information
delivery
process. As a consequence, a major challenge is to allow various
applications
to attain interoperability and sharing of content and functionality.
Personalization is becoming increasingly important in the semantic web
context
enabling shared content and services to be tailored to the needs of
individual
users. The rapid expansion of
semantic-enriched services on the web results in exponential growth of
the
people who use such services. Users differ in many aspects, e.g.
capabilities,
expectations, goals, requirements, preferences and usage context. To
truly fulfill the Semantic Web vision for
improving the way
computers and people work together, the user perspective has to be
taken into
account. The one-size-fits-all-users approach to developing web
applications is
becoming outdated. Personalization functionality on the Semantic Web
has to be
implemented and applied to deal with user diversity. The
personalization has
been a prime concern of the user-modeling community which deals with
methods
for gaining some understanding of users, i.e. a user model, and using
that
understanding to tailor the system’s behavior to the needs of
individuals. A central role is played by methods and techniques for modeling users. Existing user modeling approaches need to be adjusted to deal with the new challenges brought by the need to deal with a diverse user population having different preferences, goals, understanding of tasks, conceptual models, etc. Added to this is the vast number of sources provided by tracking the users’ activities to discover patterns of using the web in different application areas. Furthermore, new diagnostic techniques and models are needed to capture the long-term development of users’ capabilities, the dynamics of user’s goals and conceptual understanding, the uncertainty and inconsistency of naïve users’ conceptualizations, and so on. The ambitious target is to offer manageable, extendable and standardized infrastructure for complementing and collaborating applications tailored to the needs of individual users. In this endeavor a great body of Semantic Web research on the use of well-defined standards and ontologies can be adopted to provide extensibility, flexibility, interopability, and reusability. Furthermore, the open-world assumption of the Semantic web refers to the need to take into account user viewpoints ranging from domain experts to complete novices. Traditional personalization and adaptation architectures were suited to deal with closed-world assumption, where user modeling methods, such as overlay, bug library, constraint-based modeling and other marked discrepancies in a user and expert’s semantics as erroneous, and often called them misconceptions. New approaches for open-world user modeling able to elicit extended models of users and to deal with the dynamics of a user’s conceptualization are required to effectively personalize the Semantic Web. |
