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

Correct link: http://www.deri.ie/fileadmin/documents/DERI-TR-200 7-04-20.pdf

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/.

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."

Some of their software is at http://www.deri.ie/publications/tools/
but not the "yars2" world-record-busting supergadget.

Ok so it's not public and someone from the project posted a PDF with more information than the press release. http://www.deri.ie/fileadmin/documents/DERI-TR-200 7-04-20.pdf I'd like to play with RDF someday when I have free time.

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.

DERI

As (one version of) its name implies ("Really Simple Syndication"), RSS is an excellent way to get your content out to the feed consuming public (people or systems). However, since it is so generic, it has its limitations. When you see an RSS feed, how do you know what it is? Did it come from a blog, a bulletin board, a news site, your aunt's recipe site, a bookmarks list or a set of recently updated photos? Apart from an analysis of the "generator" string, the proposed RSS 3.0 doesn't easily solve this existing problem. How is content related to other content? Have there been any replies or comments on this content? Is item 1 a reply to item 2?

For my part, I'm interested in content that comes from online community discussions: blogs, mailing lists, bulletin boards, newsgroups - something where one person makes a post on a 'forum' and someone replies to that post.

Researchers in our Semantic Web cluster at DERI, NUI Galway have been working on an open specification for describing communities using online discussion forums, leading to what Ryan King and others term "distributed conversations".

The result is SIOC, standing for Semantically-Interconnected Online Communities .

The initial version of our SIOC specification has been drafted. It can be used in on its own (having a complete set of terms) or in conjunction with other RDF formats such as RSS 1.0 (and 1.1).

At the moment, online communities are islands that are not interlinked, and the SIOC ontology has been proposed to not only link these communities but to leverage data in ways that were previously unknown.

While there are many (useful) classes and properties in SIOC, it can essentially be boiled down to: Users create Posts that are contained in Forums that are hosted on Sites, e.g.

Site -> host_of -> Forum -> container_of -> Post -> has_creator -> User

Posts have reply Posts, and Forums can be parents of other Forums.

In terms of producing metadata, we've started with SIOC exporters for open-source discussion systems such as WordPress and Drupal / CivicSpace, and more are on the way. We'd also love to get input from creators of other community discussion systems. Thanks.
