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.

Zhe 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). 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

"Your are here: University Leipzig » AKSW » projects » DL Learner » ORE ORE-Tool The ORE (Ontology Repair and Enrichment) tool allows for knowledge engineers to improve an OWL ontology by fixing inconsistencies and making suggestions for adding further axioms to it. "

Navigational Knowledge Engineering is a light-weight methodology for low-cost knowledge engineering by a massive user base. Although structured data is becoming widely available, no other ....

is a tool providing support for agile, distributed knowledge engineering scenarios. OntoWiki facilitates the visual presentation of a knowledge base as an information map, with different views on instance data. It enables intuitive authoring of semantic content, with an inline editing mode for editing RDF content, similar to WYSIWIG for text documents.

Federated knOwledge eXtraction Framework FOX is a framework that integrates the Linked Data Cloud and makes uses of the diversity of NLP algorithms to extract RDF triples of high accuracy out of NL. In its current version, it integrates and merges the results of Named Entity Recognition, Keyword Extraction and Relation Extraction tools.

LIMES is a link discovery framework for the Web of Data. It implements time-efficient approaches for large-scale link discovery based on the characteristics of metric spaces. It is easily configurable via a web interface. It can also be downloaded as standalone tool for carrying out link discovery locally.

ASKW is currently funded with the following regional, national and European research projects

"The DL-Learner software learns concepts in Description Logics (DLs) from user-provided examples. Equivalently, it can be used to learn classes in OWL ontologies from selected objects. It extends Inductive Logic Programming to Descriptions Logics and the Semantic Web. The goal of DL-Learner is to provide a DL/OWL based machine learning tool to solve supervised learnings tasks and support knowledge engineers in constructing knowledge and learning about the data they created.

"Querying Wikipedia like a Semantic Database DBpedia is a community effort to extract structured information from Wikipedia and make this information available on the Web. DBpedia allows you to ask sophisticated queries against Wikipedia and to link other datasets on the Web to Wikipedia data."

A Semantic content editor based on TinyMCE WYSIWYG editor. RDFaCE is created as a proof of concept for WYSIWYM (What You See Is What You Mean) concept. WYSIWYM aims to enable end-users to easily annotate their content using RDFa and Microdata markups. RDFaCE employs external NLP APIs to suggest namespaces, properties, URIs and to automatically annotate content.
