Context-awareness is highly desired across several application domains. Semantic Web
Services (SWS) enable the automatic discovery of distributed Web services based on
comprehensive semantic representations. However, although SWS technology supports
the automatic allocation of resources for a given well-defined task, it does not entail
the discovery of appropriate SWS representations for a given situational context.
Whereas tasks are highly dependent on the situational context in which they occur,
SWS technology does not explicitly encourage the representation of domain situations.
Moreover, describing the complex notion of a specific situation in all its facets
is a costly task and may never reach semantic completeness. Particularly, following
the symbolic SWS approach leads to ambiguity issues and does not entail semantic meaningfulness.
Apart from that, not any real-world situation completely equals another, but has to
be matched to a finite set of semantically defined parameter descriptions to enable
context-adaptability. To overcome these issues, we propose Conceptual Situation Spaces
(CSS) which are aligned to established SWS standards. CSS enable the description of
situation characteristics as members in geometrical vector spaces following the idea
of Conceptual Spaces. Semantic similarity between situations is calculated in terms
of their Euclidean distance within a CSS. Extending merely symbolic SWS descriptions
with context information on a conceptual level through CSS enables similarity-based
matchmaking between real-world situation characteristics and predefined resource representations
as part of SWS descriptions. To prove the feasibility, we apply our approach to the
domain of E-Learning and provide a proof-of-concept prototype. |
