Important.Semantic.Web.Research.Areas
In this section we intend to describe a few of the more important current research topics
needing to be solved to further the development of Semantic Web services:
??? Ontology integration and translation is a major problem for interconnecting distributed
services and systems (Gruber, 1993; Heflin & Hendler, 2000; Heflin et al., 1999): How
can differing ontologies for related topics be mapped on each other?
??? Web Service orchestration, interoperation, and transaction handling needs to be
standardized (UDDI, 2001; Web Services Choreography Requirements, 2003; Web
Services Transaction, 2002).
??? Standards to allow for personalization need to find wide acceptance (PICS, n.d.; Stahl &
V?¶lter, 2005; for discussions on currently-available, yet still rarely-used standards).
Remaining.Challenges
Besides the technical questions which currently enjoy most attention, a multitude of additional
topics needs to be investigated before distributed agent systems and the Semantic
Web become truly viable.
