This  workshop aims  at creating  a forum  for discussing  a critical  issue  for the
Semantic Web, that is, scalability.  As the Semantic Web evolves, scalability becomes
increasingly important.   This workshop will  focus on addressing of  the scalability
issue with respect to the development and deployment of knowledge base systems on the
Semantic Web. Typically, such systems deal with information described in Semantic Web
languages  like OWL  and RDF(S),  and provide  services such  as  storing, reasoning,
querying and  debugging. There are two  basic requirements for  these systems. First,
they have to satisfy the  application's semantic requirements by providing sufficient
reasoning support.   Second, they must  scale well in  order to be of  practical use.
Given the sheer  size and distributed nature of the  Semantic Web, these requirements
impose  additional  challenges  beyond  those  addressed by  earlier  knowledge  base
systems.  This  has been well recognized by  the community. We expect  that the above
issue  is  going to  challenge  the  Semantic  Web for  a  long  time of  period  and
significant effort is needed in order to tackle the problem.

This workshop  seeks to bring together  researchers and practitioners  to share their
recent ideas and progresses towards  building scalable knowledge base systems for the
Semantic Web. The workshop will be centered on the discussion of three major aspects:

  1. foundations, methods and technologies for pushing forward the state-of-the-art;
  2. performance evaluation and related principles, methodologies and tools;
  3. identification of important issues and future research directions.


TOPICS OF INTERESTS for the workshop include, but are not limited to:

* Reasoning mechanisms, techniques and systems
* Query evaluation and optimization
* Performance evaluation and benchmarks
* Large Semantic Web repositories
* Distributed and concurrent knowledge base systems and P2P systems
* Large scale knowledge base management
* Semantic Web-based information integration

In addition,  the workshop will include  a working session on  benchmarking and other
relevant topics solicited beforehand to participants. In order to be able to evaluate
scalability,   the  existence  of   agreed  benchmarking   datasets  is   of  crucial
importance. In many  related domains such as databases  and theorem proving, standard
benchmarks exist and  are ready to guide research on  optimization techniques. In the
Semantic Web area,  such benchmarking shave only just started to  emerge and there is
no commonly  agreed benchmark  dataset for  RDF and OWL  reasoning and  querying. The
workshop will  address this issue  in a special  working session on  benchmarking. In
this session,  existing benchmarking initiatives  will be presented and  discussed by
organizers and participants of the workshop.  The aim is to agree on a classification
of the existing datasets and requirements for additional datasets.
