General Overview

The vision of the Semantic Web has always been a global Web of knowledge parallel to the existing Web of data. This vision has been returned to numerous times, including the call for ISWC 2005 to "put the Web back in the Semantic Web", or Tim Berners-Lee's recent post on the Giant Global Graph.

While standards and technology progress towards maturity, and Semantic Computing is reaching readiness for isolated application (e.g., behind company firewalls), the challenges of the originally envisioned global Semantic Web have received less attention. We expect millions, even billions, of knowledge and service providers and consumers to interact, integrate and coordinate (Figure 1). Technological solutions paying tribute to the issues of scalability, heterogeneity, dynamism, distributedness and openness that come along in such an environment are thus a necessity.

With this workshop we aim at bringing together promising cutting-edge middleware and Semantic Computing research, which - in integration and coordination rather than in current isolation - address the aforementioned challenges and can form a new semantic middleware layer that enables the global Web of knowledge and services, and hence the true Semantic Web vision. We address the traditional issues of data and process heterogeneity, however with a clear focus on large-scale, open and distributed environments, i.e. in settings that match the Semantic Web in the true Web sense, rather than on a corporate or even application level.

Middleware technology is traditionally seen to provide the functionality necessary to abstract providers and consumers from syntactic and technical heterogeneities. However, it is clear that for the Semantic Web, current solutions such as CORBA are not appropriate. The same holds for the Semantic Web service approaches proposed in the last years, which focus on the automation of the tasks in the process of using Web services and building service-oriented architectures (publishing, discovery, composition). For a truly global Semantic Web it is necessary that novel middleware solutions are developed and that further synergies between existing Semantic Computing and non-semantic technologies are exploited in integrated manners. The outcome of the workshop is thus expected to provide new insights, ideas, and technologies that enable a semantic middleware that delivers an interaction and coordination platform, and that virtually grants access to the available knowledge and services on the global Semantic Web.

In consequence the workshop focuses on three cutting edge Semantic Computing research areas whose integration is expected to enable the new semantic middleware:

The workshop will collect the best results from these fields, while clearly favoring proposals that might deliver solutions to all three of them. We clearly focus on approaches that exploit the synergies between the three fields in order to develop novel and promising technologies towards a global Web of knowledge and services.

Personal Semantic Web Through A Space Based Computing Environment

The Semantic Web in its current form represents information that is either static or monotonically changing. It has its roots in the World Wide Web and thus takes this web-wide persona. The information and ontologies used have standard web-wide semantics grounded in common and generally accepted real-world concepts. Deviation from this - at least in the semantic sense is not permitted.

Much of the usage of information - that will invariably become part of the Web - will be personal and/or local; its semantics, structure and adherence to real-world concepts will be grounded by the local users of that information resulting in many localised Semantic Webs.

These local Semantic Webs will contain information that is highly dynamic, non-mononticaly changing, adhering loosely (if at all) to their stated ontologies or even not to any standardised, written, commonly understood ontology and behave and be reasoned about according localised, non-standard and non-intuitive logics.

The dynamicity and monotonicty of information in and forming the Semantic Web will vary depending upon locality and be organised according to person, usage etc as - what we term - spaces.

We describe here our vision and an architectural concept regarding the development of these small, localised information or knowledge spaces by which persons via autonomous agents interact through control-flow-free mechanisms.
