As the Semantic Web evolves, scalability becomes increasingly important. This joint workshop will focus on addressing the scalability issue with respect to the development and deployment of 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, analysis, etc. There are two basic requirements for these systems. First, they have to satisfy an application's semantic requirements. 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 new challenges beyond those addressed by previous systems. This has been well recognized by the community as demonstrated by the excitement around the billion triples challenge.
For 2012, the 8th International Workshop on Scalable Semantic Web Knowledge Base Systems (SSWS2012) and the 2nd Workshop on High-Performance Computing for the Semantic Web (HPCSW2012) are merging together for the first time to address this broader issue of scalability. The event is the 2012 Joint Workshop on Scalable and High-Performance Semantic Web Systems (SSWS+HPCSW 2012), collocated with the 11th International Semantic Web Conference in Boston, USA. This joint workshop will have two tracks regarding scalability: one for knowledge base systems, and another for high-performance computing.
We expect that the issue of scalability is going to challenge the Semantic Web for a long period of time and significant effort is needed in order to tackle the problem. This joint workshop seeks to bring together researchers and practitioners to share their recent ideas and progress towards building scalable systems for the Semantic Web; participants from related disciplines such as Artificial Intelligence, Databases, Information Integration, Supercomputing, and High-Performance Computing are also welcome.
This track 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; and (3) identification of important issues and future research directions. Topics of interest for the track include, but are not limited to:
Over the last several years, there has been an increase of research in parallel Semantic Web data processing (SWDP) in both the Semantic Web community and the high-performance computing (HPC) community. As specific examples, use of HPC won the 2009 billion triples challenges, a parallel inference engine won the 2010 IEEE SCALE challenge, and the SuperComputing conference has had a birds-of-a-feather on semantic database processing for the last two years. Such events warrant special attention to scalability achieved by means of HPC, and this track seeks to facilitate synergy between relevant communities as well as between academia and industry.
