Our plug-in extends the Protégé Ontology Editor (link is external) by a set of useful features for Aspect-Oriented Ontology Development, such as
We are taking the complexity out of Aspect-Oriented Ontology Development with our editing component for Web Protégé (link is external) that lets ontology developers use aspects as editing contexts which can be switched by the click of a button.
Our aspect-oriented extension of the OWL API (link is external) allows Semantic Web application developers to make use of the benefits of Aspect-Oriented Ontology Development (AOOD) programmatically simply by adding Java annotations (link is external) to their code.
A Java library for ISO Common Logic and OWL ontologies and a reference implementation for the work-in-progress standardization effort API for Knowledge Platforms (API4KP).
Provalets are rule-based software agents that act as inference component providing rule-based data access, processing and analytics functionalities using the Prova rule engine and language. Provalets are automatically deployed in trusted OSGi component run-time environments such as OSGI-compliant smart edge devices, as well as more centralized cloud infrastructures, ESBs or agent frameworks. The component-based agent model of Provalets allows encapsulating data intensive routines and rule-based analytic, decision and reaction logic at the component (e.g. device) level, ensuring, e.g., interface-based access, data/information hiding and privacy.

RoleDisc is a plugin that provides Role Discovery features within the collaborative software Confluence. Still in a prototype phase, the plugin provides a visual representation of the users who worked on each page as well as a global graph that shows the interactions between users and assigns roles to each one of them. Future releases will also mine the content of the pages to provide deeper insights about the activities of all actors in the system.

The CER System Prototype is a smart knowledge management platform. It integrates advanced information extraction capabilities and builds a knowledge graph where coherent entity structures can be extracted in ordert o offer better insights into certain topics. A full description can be read in our technical reports

The Ontology Modularization Framework is based on the SONIVIS:Tool for network analysis and allows for easy ontology analysis and modularization. (more)
SVoNt is a version control system for ontologies based on the SVN-system which is well-known from software engineering. The major difference to other approaches for ontology versioning is our focus on the visualization of revisions of changes on the concept level. (more)
OntoMaven is a set of Maven plug-ins supporting the management and engineering of ontologies from distributed (Maven) ontology repositories. (more)
To support the processs of creating such concept groups for the documentation of ontologies we extended the SpecGen tool with an automatic concept grouping functionality. (more)
COLM is based upon a two parts ontology lifecycle, which has been concluded from requirements that we derived from an analization of industrial needs. (more)
Corporate Semantic Web Search and Semantic Recommendation solutions, tools and use cases. (more)
SemMF is a flexible framework for calculating semantic similarity between objects that are represented as arbitrary RDF graphs. (more)
A framework supporting the semantic annotation, publishing and search of multi-media contents. (more)
Usage of background knowledge about events and their relations to other concepts in the application domain can improve the expressiveness and flexibility of complex event processing systems. (more)
Prova is a highly expressive distributed Corporate Semantic Web rule engine which combines declartive rules with dynamic object-oriented Java, Semantic Web technologies, and enterprise service-oriented computing and complex event processing technologies. (more)
A Rule-based Agent Architecture for Semantic Business Process Managment (SBPM), Semantic eScience, Semantic Complex Event Processing (SCEP), personalized Question-Answering Systems, Semantic Web Reputation and Trust Management and the Pragmatic Web. (more)
A Semantic WIKI for Semantic Business Process Management and Workflow. (more)
A Semantic Extension PlugIn for BPMN Modeling Tool Oryx. (more)
Loomp is a Web 3.0 Semantic Content Authoring tool developed by the Corporate Semantic Web group. It supports: (1) Create semantically enhanced content as easy as to format texts italic, without knowing about semantic technologies, and with automatically proposed annotations. (2) Compile content and publish in various formats. (3) Support the reader by highlighting the relevant information. (more)
In this project we develop extensions to existing wiki systems that ease the pain of creating links between wiki pages. (more)
Finding Experts in a Collboration Wiki (more)
Tagging has become the most common way of annotating information and knowledge in a wide range of applications. The activity of tagging consists in creating an association between a resource (information) and another entity (a tag). (more)
Trendontologies improve the quality of automated trend detection. We used a knowledge-based approach and utilized formalized expert knowledge which we used to model three lightweight trend ontologies. (more)
In order to retrieve RDF-triples from a text stream, we have to preprocess texts. Our preprocessing component uses statistical parser from Stanford University and creates a timeline with parsed texts. (more)
DBpedia Deutsch stellt die strukturierten Informationen der deutschen Wikipedia frei zur Verfügung. Dabei ist dies ein Teil des internationalen DBpedia Projektes, wobei wir uns auf die Extraktion und Bereitstellung der Informationen der deutschen Wikipedia beschränken. (more)
At the moment some ontology editors are available to model ontologies in research and industry, e.g., Protegé, TopBraid Composer, and OntoStudio. However, these tools are too complex and offer too much functionality that even experts in semantic technologies can hardly operate them properly. In contrast, our work focuses on developing an easy-to-use and light-weight ontology editor which can be used by non-experts w.r.t. semantic technologies. (more)
