Protégé DL-Learner plugin 0.1
Today, we released a plugin for Protege 4, the upcoming release of the popular ontology editor. The plugin allows you to get suggestions for axioms you may want to add to your OWL ontology by analysing the instance data using the DL-Learner framework. You can get an idea of how it can help you in [...]
OSM Linked Geo Data extraction, browser & editor
We were working in the last weeks on bringing geo data derived from the marvelous OpenStreetMap project to the data web. This work in progress is still far from being finished, however, we would like to share some first preliminary results:
A vast amount of point-of-interest descriptions was extracted from OSM and published as Linked Data [...]

Agile Knowledge Engineering and Semantic Web (AKSW)
The Research Group Agile Knowledge Engineering and Semantic Web (AKSW) is hosted by the Department for Business-oriented Information Systems (BIS) of the Institute of Computer Science (IfI) / University of Leipzig.
Goals
- Development of methods, tools and applications for adaptive Knowledge Engineering in the context of the Semantic Web
- Research of underlying Semantic Web technologies and development of fundamental Semantic Web tools and applications
- Maturation of strategies for fruitfully combining the Social Web paradigms with semantic knowledge representation techniques
AKSW is committed to the open source, open access and open knowledge movements.
Projects
AKSW started a number of high impact R&D projects:
- Triplify tackles the chicken-and-egg problem of the Semantic Web by providing a building block for the “semantification” of Web applications.
- SoftWiki – Distributed, end-user centered Requirements Engineering for evolutionary software development
- Cofundos.org – is a platform for community innovation and funding of open-source software: many individual donations and contributions are pooled together in order to realize bright software ideas.
- Powl – our Semantic Web application development platform, OntoWiki is an adaptive semantic collaboration tool based on Powl implementing the Web 2.0 idea of an architecture of participation.
- DBpedia is a community effort to extract structured information from Wikipedia and to make this information available on the Web.
- DL-Learner tackles the problem of learning concept/class definitions in Description Logics / OWL from examples
- xOperator – A semantic agent for xmpp / jabber network which finds and shares content about resources (using RDF/SPARQL) for you and your jabber friends.
- OpenResearch.org – a semantik Wiki for collecting and sharing scientific meta-data such as Cf Ps, tool descriptions, research profiles, conference statistics etc.
- Semantic data integration: R2D2 – a PHP tool and API component for mapping relational database content to RDF based ontologies. Semantic LDAP – bridges the gap between LDAP and the Semantic Web.
Demos
Please have a look at our demos:
DBpedia.org: Querying Wikipedia like a knowledge base.
Cofundos.org: Community innovation and funding for open-source.
Triplify.org: Make Web applications better mashable by exposing semantics.
xOperator: Interconnecting the Semantic Web with Instant Messaging Networks.
Wikipedia Query Builder: Query the over 10M facts extracted from Wikipedia
OntoWiki: use social semantic collaboration to build comprehensive knowledge bases
DL-Learner: learn class descriptions by semantically analysing objects.
DBpedia Relationship Finder: allows to explore the DBpedia dataset to find relationships between two things.
DBpedia Navigator: search/browse in DBpedia and get recommendations on what you may be looking for.
