Ontology-Based Support for Complex Events

Ontology-based Process Support

This paper describes a principled approach towards creating an IT-support environment for knowledge workers. Starting in the analysis phase our approach paves the way for putting an intelligent assistant to work within a typical business process environment. Thereby, this support intelligence is centred around the interdependencies between documents providing the background knowledge and busine...

NLP-based support for ontology lifecycle development

This paper describes the implementation of an approach to modelling the dynamics of the propagation of textually derived semantic information, in particular with respect to networked ontologies. On the one hand, new ontologies may be generated automatically from textual data, or existing ontologies may be modified or extended according to new evidence. This can cause problems for large or netwo...

Ontology-based Extraction of Transcription Regulation Events

I present an on-going work on extraction of transcription regulation events from text by using an ontology which plays a central role in integrating information from different sources. The events of transcription regulation are expressed in the literature with a high degree of compositeness. They have elements such as event types, participants, and attributes. These elements are associated with...

Ontology based complex object recognition

This paper presents an object categorization method. Our approach involves the following aspects of cognitive vision : machine learning and knowledge representation. A major element of our approach is a visual concept ontology composed of several types of concepts (spatial concepts and relations, color concepts and texture concepts). Visual concepts contained in this ontology can be seen as an ...
