Scope and Topics

There has been an explosion recently in the development of Semantic  
Web (SW) applications in various application areas (e.g. in e-science,
digital libraries). As the size of the SW is expected to further grow  
in the coming years, scalability and performance of SW systems becomes
increasingly important. Typically, such systems deal with information  
described in SW languages like OWL and RDF(S), and provide services for
storing, querying, updating and reasoning over large volumes of  
triples. Defining adequate performance targets is one of the major  
challenges
for the development of SW systems that integrate reasoning with  
manipulation of large scale RDF/OWL ontologies and their instances. In
particular, many traditional reasoning algorithms raise serious  
scalability concerns because they do not rely on secondary storage and  
appropriate
indexing techniques.

In order to be able to evaluate the scalability and performance of SW  
systems, the existence of agreed benchmarking datasets is also 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 SW area, such benchmarks have only  
just started to emerge (e.g. LUBM). Yet, there is no commonly agreed  
benchmark
covering the complexity of real SW ontologies and related instances.  
Further research need to be conducted on the synthetic generation of SW
datasets that simulate the various distributions of graph features (in/ 
out property degrees, subsumption relationships, etc.) exhibited by
existing SW applications.


TOPICS OF INTERESTS for the IJSWIS special issue include, but are not  
limited to:
*        Foundations, methods and tools for SW benchmarking;
*        Scalability metrics and performance targets of SW systems;
*        Performance evaluation of existing SW query, update and  
reasoning services;
*        Design and implementation of high performance SW systems;
*        Analysis of synthetic and real large-scale SW repositories.



Submission Process

Submissions to this special issue should follow the journal's  
guidelines for submission (http://www.idea-group.com/journals/details.asp?ID=4625&v=guidelines 
).
After submitting the paper, please also inform guest editors by an  
email with the paper ID assigned by the submission system. Papers must  
be of
high quality and should clearly state the technical issue(s) being  
addressed as related to scalability and performance of SW systems.  
Research
papers should present a proof of concept for any novel technique they  
are proposing. Case studies should discuss the significance and  
applicability
of their proposed architecture/system. If a submission is based on a  
prior publication in a workshop or conference, the journal submission  
must involve
substantial advance (a min. of 30%) in conceptual terms as well as in  
exposition (e.g., more comprehensive testing/evaluation/validation or  
additional
applications/usage).


All papers must be submitted by September 1, 2008. The editors  
recommend that the number of pages should not exceed 35. All papers  
are subject to
peer review performed by three established researchers selected from a  
panel of experts established for this special issue. Accepted papers  
have an
opportunity for further revision and an additional round of reviewer  
feedback. Information on the journal with online submission can be found
at: http://www.ijswis.org. Please submit manuscripts through that  
online system.
