Agile Knowledge Engineering and Semantic Web (AKSW)

The Research Group Agile Knowledge Engineering and Semantic Web (AKSW) is hosted by the Chair of Business Information Systems (BIS) of the Institute of Computer Science (IfI) / University of Leipzig as well as the Institute for Applied Informatics (InfAI). It consists of the three subgroups Emergent Semantics, Machine Learning and Ontology Engineering, and Semantic Abstraction.

AKSW tools prominently featured in TÜB?TAK
Börtecin Ege wrote an article on the Semantic Web in the December issue of TÜB?TAK (The Scientific and Technological Research Council of Turkey) prominently featuring DBpedia, Relfinder, LIMES, SPARQL Benchmark and other AKSW related research projects.

NLP Interchange Format (NIF) 1.0 Spec, Demo and Reference Implementation
The NLP Interchange Format (NIF) is an RDF/OWL-based format that aims to achieve interoperability between Natural Language Processing (NLP) tools, language resources and annotations. The core of NIF consists of a vocabulary, which can represent Strings as RDF resources. A special URI Design is used to pinpoint annotations to a part of a document. These [...]

DBpedia SPARQL Benchmark paper wins ISWC2011 best-paper award
The closing ceremony of ISWC2011 in Bonn is just over and we are excited to have won the best research paper award with our paper: Mohamed Morsey, Jens Lehmann, Sören Auer, Axel Cyrille Ngonga Ngomo: DBpedia SPARQL Benchmark ? Performance Assessment with Real Queries on Real Data. To appear in Proceedings of 10th International Semantic [...]

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 has launched 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-centred Requirements Engineering for evolutionary software development
  • OntoWiki is a Semantic Data Wiki as well as an Application Framework providing support for agile, distributed knowledge engineering scenarios.
  • DBpedia is a community effort to extract structured information from Wikipedia and make this information available on the Web.
  • DL-Learner tackles the problem of learning concepts / class expressions in Description Logics / OWL from examples.

Please look at the projects page for a comprehensive description of AKSW's funded as well as community and open source projects.

Demos

Please have a look at our demos:


DBpedia.org: Querying Wikipedia like a knowledge base.

LinkedGeoData.org: adding the spatial dimension to the Semantic Web.

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: Earn class descriptions by semantically analysing objects

DBpedia Relationship Finder: Allows you 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
