Scripting languages play a central role in the development of flexible, lightweight semantic web applications. Hence, the workshop aims to bring together developers of the RDF base infrastructure for scripting languages with practitioners building applications using these languages. It includes a scripting challenge which will award a prize (an Apple iPod Video or alternatively Euro 200 cash) to the most innovative small scripting application or mashup. The workshop is co-located with 4th European Semantic Web Conference and takes place on June 6, 2007 in Innsbruck, Austria.

"Cofundos.org is a novel platform for spurring innovation and development of open-source software. It can have quite an impact on open-source and web collaboration in general: Cofundos.org is about revealing bright ideas regarding the development of open-source software and attracting a critical mass for their realization. The main idea of Cofundos.org is to share innovative (open-source) ideas, to refine them and to mobilize funding for their realization.\r\n\r\nThere exist now already a number of Web sites and services empowering its users to pool resources in order to achieve certain goals.\r\nPledgebank for example is a universal pledging service, whereas Fundable is a platform for goal-oriented fundraising.Change.org, tries to connect people concerned about certain causes with non-profit organizations that relate to them. And when it comes to widgets, ChipIn makes it easy to embed dynamic fundraising boxes into any website. There are a number of Facebook applications as well.\r\n\r\nMissing so far was a platform exploiting the power of many distinctively for open-source software development. This is the aim of Cofundos.org. The concept is based on the following principles:\r\n\r\n
    \r\n
  • Open-knowledge and open-source. All ideas and contributions on Cofundos are licensed under a Creative Commons Attribution License. All project outcomes must be licensed under an OSI approved open-source license.
    • \r\n
  • Reputation and community. Bright ideas and excellent solutions often originate from outstanding individuals. But it needs a community to mature these ideas and solutions and in order to bring the critical mass together for their realization.
    • \r\n
  • Fairness and trust. An open, accountable and transparent environment will foster fair communication and trustworthy relationships between its users.
    • \r\n
  • Big impacts can be achieved in small steps. Conceiving and realising bright ideas does not require many year developments or huge amounts of funding. Their realisation can be achieved by bringing together innovative ideas with clearly defined features and requirements based on community involvement and fostering their accomplishment by committed specialists.\r\n
    • \r\n
\r\n\r\nIn addition to these principles, Cofundus.org is entirely semantically interoperable - all (non-sensitive) content is accessible in the form of Atom, JSON feeds or as RDF export. Cofundos invites everybody to register or login using OpenId and to post software ideas, requirements or even bid for the realization of existing projects.\r\n\r\nCofundos is operated by the Agile Knowledge and Semantic Web research group (AKSW) at the Department of Business Information Systems at Universität Leipzig.

"\"xOperatorFresh from the subversion repository, our new semantic agent project xOperator is now able to play with my local OntoWiki knowledge bases. The initial development to this tool will be done by Jörg Unbehauen as part of his master thesis.\r\n\r\n
xOperator tries to create a decentralized network of trust. Information is shared in the form of resources, which can be anything (even the information that you are selling your old washing machine). In a later stage it enables you to find friends of friends like centralized services, can already. At the end of the road, xOperator might even be able to find the best product for you without the normally necessary tedious internet research. Companies will be able to offer semantic annotated information about their products, giving the customer a new way of yet unknown price transparency.
\r\n\r\n\r\n\"FirstAlthough xOperator is able to use any SPARQL endpoint out there, our main use case is to marry it with OntoWiki. Users should be able to use the agent just as an additional view to the knowledge bases of their OntoWiki installation.\r\n\r\nTo do this, it will be possible not only to ask the agent with special query languages like SPARQL but also to ask him with natural language. To achieve this, xOperator will map templates based on the Artificial Intelligence Markup Language (AIML) to SPARQL queries and transform the XML result set to the instant message which will be send back to the user.\r\n\r\n

Implementation Status

\r\n
The agent is able to log into existing accounts and can receive querying and configuration commands. The template based query generation is still a bit quirky. Queries can only be executed against locally configured data stores, the p2p part is not yet implemented.
\r\n\r\nIf you're interested in the project, please write to the public mailing list xoperator-public in our SourceForge area. The official homepage is http://aksw.org/Projects/xOperator" .

Most notably, DL-Learner now has a flexible component based design, which allows to extend it easily with new learning algorithms, learning problems, reasoners, and supported background knowledge sources. A new type of supported knowledge sources are SPARQL endpoints, from which DL-Learner can extract knowledge fragments, which enables learning classes even on large knowledge sources like DBpedia. Furthermore, DL-Learner now supports learning from positive examples only, inclusion axiom learning, the usage of N-Triple files as background knowledge, the OWL API reasoner interface, and has a more powerful web service interface.

"Solely for the reader community of the AKSW blog we have a technology preview, which we hope will increase the amount of semantics on the Web and maybe even provide the missing spark for a large scale deployment of semantic technologies on the Web. Triplify is a minimalistic technique to \"semantify\" Web applications by exposing information from their relational database backends as RDF, JSON and Linked Data. The required effort to do so is minimal - just some SQL queries selecting the information to be made available have to added to the Triplify configuration. Triplify cares about everything else.\r\n\r\nThe Triplify implementation and further information is available from the still preliminary web site at: http://triplify.org" .

For those who missed the first Triplify announcement:\r\n\r\nTriplify enables the effortless “semantification” of Web applications. Triplify is a small plugin for Web applications, which reveals the semantic structures encoded in relational databases by making database content available as RDF, JSON or Linked Data.\r\n\r\n\"Triplify\r\n\r\nTriplify is very light weight: It consists just of few files with less than 500 lines of code. For a typical Web application a configuration for Triplify can be created in less than one hour and if this Web application is deployed multiple times (as most open-source Web applications are) the configuration can be reused without modifications.\r\n\r\nTriplify makes Web applications easier mashable and lays the foundation for next generation, semantics based Web searches.\r\n\r\nMore infos, the software release, some example configurations for OpenConf, Open Journal Systems, WackoWiki, WordPress and Drupal are available from: http://triplify.org" .

I will give a talk about our xOperator project at the European Semantic Web Conference (ESWC2008) on Tenerife next Wednesday. The xOperator is an agent for xmpp / jabber network which queries and shares trusted resources (using RDF/SPARQL) for you and your jabber friends. In addition to the full paper, we got good reviews for the demo session too. So I present the xOperator in a more technical way at the demo session on Tuesday.

Another project which we started here is RDFAPI-JS. I present this work at the Scripting for the Semantic Web Workshop (SFSW2008) which is co-located with the ESWC. RDFAPI-JS is used for RDFa widgets which can be used to modify embedded RDF models.

More information about the LSWT can be found (in German) at: http://aksw.org/Events/2009/LeipzigerSemanticWebDay." . "2009-04-30T14:54:15"^^ . . . "2009-02-10T00:56:14"^^ . "Paper on Triplify accepted at WWW 2009" . "Our paper \"Triplify - Light-weight Linked Data Publication from Relational Databases\" was accepted for the Semantic Data Web track at this years World Wide Web Conference. In the paper we discuss the motivation, workings of Triplify as well as its spatial and update log extensions. WWW 2009 will take place from April 20th to 24th in Madrid. Besides paper presentations WWW 2009 also includes a workshop on Linked Data on the Web (LDOW2009)." . "2009-02-11T09:03:47"^^ . . . "2009-02-11T15:42:27"^^ . "DBpedia Live Extraction Test Server" . "We currently feature a live extraction of DBpedia on one of our servers. The live extraction is aimed at bringing Wikipedia and DBpedia closer together. Errors in DBpedia can soon be corrected directly by editing the corresponding Wikipedia article.\r\nWe created a test page on Wikipedia for observing the effects of the live extraction on the endpoint at: http://en.wikipedia.org/wiki/User:DBpedia\r\n\r\nOur further plans regarding the live extraction are:\r\n
    \r\n
  • Changing the current Virtuoso version to 6.0, which will come out soon (counting the days...)\r\nNote: since Virtuoso has a Wikipedia page with an Infobox, you could tell your personal semantic agent to notify you, as soon as the 6.0 release is out, as it can now be queried with SPARQL on DBpedia-Live. See the Wikipedia page, DBpedia and DBpedia-Live (Addition: Kidehen just contacted us and installed a DBpedia vad on our DBpedia mirror and now the data is accessible via LinkedData also. See http://db0.aksw.org:8890/resource/Virtuoso_Universal_Server. Note the owl:sameAs link to the original DBpedia.)
    • \r\n
  • Getting all extractors online (some are deactivated right now)
    • \r\n
  • Gathering feedback from the community, as DBpedia is a vital resource of the Semantic Web.
    • \r\n
  • Deploy the Live-Extraction on the public DBpedia endpoint.
    • \r\n
  • Deploy an OntoWiki on our DBpedia-Live mirror.
    • \r\n
\r\n\r\n\r\nAs we are in the phase of active developments, we are looking forward to receive your feedback and comments on the live extraction and our further ideas (described below).\r\n\r\nWorkings of the algorithm:\r\nEach extractor now has 3 different states:\r\nActive, Keep, Purge, which can be used (in order) to update triples, leave triples unchanged, remove triples.\r\nAs each extractor is responsible for certain properties in DBpedia and the overlapping is low, we used this to determine which triples to keep and which to delete. Let's say an article like dbpedia:Berlin is updated. First the current triples which have dbpedia:Berlin as subject are retrieved from DBpedia-Live via a SPARQL. A Diff is created and all triples that changed are deleted and all new ones are updated. When an extractor, such as the ExternalLinksExtractor, is in status 'Keep' a filter is imposed on the SPARQL query, which filters all triples with properties corresponding to the extractor (in this case http://dbpedia.org/property/reference) . The triples, which are filtered out during retrieval, do not show up in the Diff and will therefore be deleted. Certain properties such as owl:sameAs are always included in the filter, as they are not generated by any DBpedia extractors.\r\nAlso more sophisticated filters like triples with a certain namespace as predicate and object. This gives control over which data to keep, remove, update in DBpedia.\r\n\r\nThis is an example of the current filters imposed on the queries as on our test server (!regex is very fast, while regex isn't). From these, It is also possible to guess which extractors are currently still deactivated:\r\nSELECT * WHERE { ?p ?o.FILTER(\r\n((!regex(str(?p), 'http://dbpedia.org/property/wikilink'))\r\n&&(!regex(str(?p), 'http://dbpedia.org/property/wordnet_type'))\r\n&&(!regex(str(?p), 'http://www.w3.org/2002/07/owl#sameAs'))\r\n&&(!regex(str(?p), 'http://dbpedia.org/property/abstract'))\r\n&&(!regex(str(?p), 'http://www.w3.org/2000/01/rdf-schema#comment'))\r\n&&(!regex(str(?p), 'http://xmlns.com/foaf/0.1/depiction'))\r\n&&(!regex(str(?p), 'http://xmlns.com/foaf/0.1/img'))\r\n&&(!regex(str(?p), 'http://dbpedia.org/property/hasPhotoCollection'))\r\n&&(!regex(str(?o), 'http://dbpedia.org/class/yago/'))\r\n&&((!regex(str(?p), 'http://www.w3.org/1999/02/22-rdf-syntax-ns#type') \r\n||!regex(str(?o), 'http://dbpedia.org/ontology/') )))). }\r\n\r\n\r\nOpen issues:\r\n
    \r\n
  • synchronization with the LOD cloud, e.g. automatic creation of links if new DBpedia instances appear.
    • \r\n
  • as there is no static state in DBpedia-Live any more Yago and Umbel also have to be loaded on the fly
    • \r\n
\r\n\r\n\r\nA collection of ideas on an update log:\r\n
    \r\n
  1. OWL 2 Axiom Annotations: Although this would result in at least 5 times more triples, it would represent a clean solution, tackling many problems. As the extractors already have URIs the provenance of a triple would be clear. Also additional information like confidence can be kept. DBpedia is quite a small dataset compared to Bio2RDF (2.5 billion triples) and DBtune (14 billion), so performance might not be a problem.
    2. \r\n
  2. making a service that could parse older revisions of Wikipedia pages on the fly and recreate older versions.
    3. \r\n
  3. making Named Graphs, any ideas?
    4. \r\n
  4. Additionally, the update log idea of the WWW paper about Triplify can be applied
    5. \r\n
\r\n\r\nSome ideas on a Live update stream to create synchronized mirrors of DBpedia (far future):\r\n1. release DBpedia dumps more frequently, e.g. once a week\r\n2. Provide a method to receive updates via a push or pull mechanism in SPARUL\r\n\r\nDBpedia is a joint effort of AKSW (Sören Auer, Jens Lehmann, Sebastian Hellmann), Freie Universität Berlin (Chris Bizer, Georgi Kobilarov, Anja Jentsch) and OpenLink Software, who provide the public endpoint and the powerful Virtuoso Universal Server. \r\n" .

\"OntoWiki
\r\n

We've prepared a brand new OntoWiki Screencast from the source trunk to show some special features of the new OntoWiki.

\r\n

In particular, this screencast demonstrates\r\n

    \r\n
  1. the model dashboard with current discussions,
    2. \r\n
  2. discussions on specific resources,
    3. \r\n
  3. how to create a new property on a resource,
    4. \r\n
  4. how to link a local resource with an external one (from sindice), and
    5. \r\n
  5. how to gather linked data from this external resource.
    6. \r\n
\r\n

\r\n

From a technical point of view, this screencast demonstrates our new RDFa widget library (thx to Norman Heino), our data wrapper system (thx to Philipp Frischmuth) and our new map plugin (thx to Nathanel Arndt).

\r\n

The screencast is based on revision 3333 from the current trunk and uses the Virtuoso backend.

OntoWiki 1.0 will have an enhanced plug-in architecture and a lot of APIs that allow you to customize the user interface. In addition to plug-ins which have been around for some time, there are three new extension types:\r\n
    \r\n
  • Components
    • \r\n
  • Modules
    • \r\n
  • Wrapper
    • \r\n
\r\n\r\nIn short, components are pluggable controllers, modules are those little boxes OntoWiki has been using for some time now and wrapper are extension for extracting triples from external sources and importing them into your knowledge base.\r\n\r\nOne wrapper that ships with OntoWiki can e. g. load triples from Linked Data-enabled endpoints like Sindice or DBpedia. Among others, this feature is demonstrated in the new screencast. But the wrapper is only a part of OntoWiki's new Linked Data enhancements. A plug-in publishes resources as linked data, provided their URI shares the prefix with the domain the respective OntoWiki installation runs under and the named graph is readable.\r\n\r\nBesides extensibility, improvements in performance was one of the key goals for OntoWiki 1.0. Thus, it was only natural to make OntoWiki work with Virtuoso, one of the fastest RDF triple stores around. Besides Virtuoso, MySQL is still supported as well. It underwent, however, serious refactoring and is now based around ZendDb instead of ADOdb as its abstraction layer.\r\n\r\nA preliminary version (OntoWiki 0.9) will be released in the coming weeks. It is based on the 1.0 code base but doesn't contain all the features we'd like to include in 1.0." .

We have chosen CC-BY 2.0 since it was ported to Germany, however you are right it is probably better to use the most recent version and to omit the porting, We updated the website accordingly. CC-BY however is the license for all textual contributions submitted to the platform not for any sourcecode releases.\r\n\r\nFor sourcecode licenses, we did not want to dictate one specific license, but rather let the community decide which one is most appropriate for a certain development project.\r\n\r\nYes, we will try to update the site to conform to the Web Content Accessibility Guidelines - a now theme/layout is currently in the works.\r\n\r\nThe project is currently hosted by the Universität Leipzig, but we plan to start a different non-profit organizational structure (e.g. foundation) later." . . . .
