Super-Fast RDF Search Engine Developed

Posted by ScuttleMonkey on from the google-to-buy-ireland dept.

The Register is reporting that Irish researchers have developed a new high-speed RDF search engine capable of answering search queries with more than seven billion RDF statements in mere fractions of a second. "'The importance of this breakthrough cannot be overestimated,' said Professor Stefan Decker, director of DERI. 'These results enable us to create web search engines that really deliver answers instead of links. The technology also allows us to combine information from the web, for example the engine can list all partnerships of a company even if there is no single web page that lists all of them.'"

    Now all we need to do is get everyone to start using RDF.... wait.. you dont even know what that is??
    It's the Resource Description Framework, which RSS is a subset of.

    Actually, only RSS 1.0 is based on RDF. The only similarity between RDF and the more popular RSS 2.0 and RSS 0.92 is that they are all based on XML.

    Hello, I am one of the main developers of SWSE. True, the press release is vague, but there is only so much you can say in a press release aimed for the general public.

    We have a Technical Report available at http://www.deri.ie/fileadmin/documents/DERI-TR-200 7-04-20.pdf that should answer most of the technical questions.

    From the abstract:

    "We present the architecture of an end-to-end search engine that uses a graph data model to enable interactive query answering over structured and interlinked data collected from many disparate sources on the Web.

    In particular, we study distributed indexing methods for graph-structured data and parallel query evaluation methods on a cluster of computers.

    We evaluate the system on a dataset with 430 million statements collected from the Web, and provide scale-up experiments on 7 billion synthetically generated statements."

    As one of the developers on the project (along with user aharth), feel free to ask any specific questions you may have here. The article is quite vague and so I refer you to a technical report at http://www.deri.ie/fileadmin/documents/DERI-TR-200 7-04-20.pdf/.

      Text search on literals is supported through Lucene. Only vanilla keyword searches are currently supported. The query syntax for the indexing is a subset of SPARQL. The code is Java and has yet to be officially released.

    If you're going to steal a joke, you need to make sure to replace all references to the original. Find / Replace works great for this.

    2 all: remove the ending slash '/' from the URL above, it will work then.
