Second Release of the DBpedia Relationship Finder. The Relationship Finder explores the DBpedia infobox dataset to find out which relations exist between two things. It can answer questions like “How are Leipzig and the Semantic Web related?“. The new version includes, amongst other changes, better algorithms and the possibility to ignore objects and properties.

OntoWiki 0.7 is now available for download. Changes in this release include

• Access Control at Model and Action level
• Enhancements in System Ontology http://ns.ontowiki.net/SysOnt/
• User Data is now FOAF compatible and managed as RDF Knowledge Base
• New SPARQL Query Shell together with a brand new SPARQL Engine
• New URI Routing (list, (class) view)
• GUI enhancements
• Several bug fixes
• Environment Changes include: New Zend 1.0.0, New RAP 0.9.5, Separation from Powl

Notes for Updaters:

• Create a new config.ini from the distributed file, the old 0.6 one doesnt work with 0.7
• Users are saved as RDF content now, you need to reregister your users.

Within the last year monthly Powl/OntoWiki downloads were skyrocketing. Check out OntoWiki’s Sourceforge statistics page, do get more details. They effectively quadrupled within the last year, reached now a level of 400-500 monthly downloads and we expect even higher increases in the upcoming year, as OntoWiki will significantly mature, include many more additional features and be overall easier-to-use also for knowledge engineering novices.

Christian Weiske, one of our diploma students, has ran some benchmarks to compare his new PHP SparqlEngineDb to some other implementations (Jena, ARC, Redland). The results are surprising - in most cases, his new SPARQL Engine is faster then all competitors.

OntoWiki 0.7, which will be released in the next two weeks, will be shipped with this new engine and a nice SPARQL shell.

Detailed benchmark results are available at cweiske.de.
