Invited Talks:

Ian Horrocks, University of Oxford


So called "Semantic Technologies" are rapidly becoming mainstream technologies, with RDF and OWL now being deployed in diverse application domains, and with major technology vendors starting to augment their existing systems accordingly. For example, Oracle Inc. recently enhanced its well-known database management system with modules that use RDF/OWL ontologies to support "semantic data management", and their product brochure lists numerous application areas that can benefit from this technology, including Enterprise Information Integration, Knowledge Mining, Finance,Compliance Management and Life Science Research. This is, however,only the first step for Semantic Web research; we need to demonstrate that the Semantic Technologies we are developing can (be made to)exhibit robust scalability if deployments in large scale applications are to be successful. In this talk I will review the evolution ofSemantic Technologies to date, and show how research ideas from logic based knowledge representation developed into a mainstream technology. I will then go on to examine the scalability challenges arising from deployment in large scale applications, and discuss ongoing research aimed at addressing them.

Semantic Web Directions

In this talk, Peter Mika will describe some of the ways in which semantic technologies are currently being used at Yahoo! in both search and online media. In turn, he will reflect on what pieces of the Semantic Web have proved to be useful for Yahoo! in the past, and where he sees the potential for future Semantic Web research.

Publishing, sharing and exploring online data

In this talk I will try to list critical challenges for making online data useful to a wide audience, including companies and citizens. Trust is such an issue which requires both research and easy-to-understand concepts for getting this across and accepted. Other issues include the need for data authorities, a simple but effective versioning strategy and new new ways of exploring data (i.e., moving beyond the Google paradigm). And, finally we need to consider whether data representation formats are really a bottleneck, or that we are just too much fixated on these.

Problem Solving Methods for the Semantic Web: back to the future

We know how to write ontologies, and we know how to publish data on the web. We even have relatively stable theories and tools for this. But once these data are published, there is neither theory nor tooling for how to build the applications that use the ontologies and datasets. In order to really propel the Web of Data forward, we need libraries of problem solving components that can be reused and reconfigured to build applications in a more cost-effective and reliable manner than is 
currently done (which is: from the ground up, every time again).

The extensive work on Knowledge Engineering in the 1990s has resulted in a systematic analysis of task-types, and the corresponding problem solving methods that can be deployed for different types of tasks. That analysis was the basis for a sound and widely accepted methodology for building knowledge-based systems, and has made it is possible to build libraries of reusable models, methods and code.

We need to re-use these lessons from the past, and adapt them to our new Web-based world. Both theories, and tools.

LOD Benchmark Council

The LODBC initiative has the following aims:

The emergence of the LODBC community will accelerate development in performance and scalability of RDF and graph databases as well as drive convergence of functionality and will finally provide the growing end user community with fair and mutually comparable metrics for guiding product selection. This constitutes a win-win scenario for both vendor and user communities and will contribute towards a rapid maturation of the technology, similarly to what has happened in the relational arena with the first TPC benchmarks.

  • Create a forum for cooperation between vendors and academia around the topic of benchmarking. A benchmarking effort without sufficient involvement from the vendor community will not be credible, hence the aspect of community building and cooperation and eventual consensus between vendors on what constitutes relevant and fair benchmarking is central to the LODBC initiative.
  • Develop benchmark workloads, data generators and test drivers for measuring the performance of RDF and/or graph databases.
  • Carry out and publish benchmarks in close cooperation with the vendors of the systems being benchmarked.
  • Provide a TPC-style auditing service for certifying results published by vendors for benchmarks endorsed by the LODBC.
  • Create a long-lived, industry supported association similar to the TPC for continued cooperation around benchmarking and for functioning as a clearinghouse for publishing audited benchmark results.
