Abstract | |||||||||||||||||
| The rapid growth of documents, web pages and other types of textual content pose a great challenge to modern content management systems. Ontologies offer an efficient way to reduce the amount of information overload by encoding the structure of a specific domain and offering easier access to the information for the users. However, all major ontology editors (such as Protégé[2], OntoStudio[3], …) are fully manual and offer little support to the users for structuring domains. OntoGen (previous version was introduced in [1]) is a semi-automatic and data-driven ontology editor focusing on editing of topic ontologies (a set of topics connected with different types of relations). The system combines text-mining techniques with an efficient user interface to reduce both: the time spent and complexity for the user. In this way it bridges the gap between complex ontology editing tools and the domain experts who are constructing the ontology and not necessarily having skills of ontology engineering. The two main characteristics of the system are: � Semi-Automatic – The system is an interactive tool that aids the user during the ontology construction process. It suggests: concepts, relations between the concepts, names for the concepts, automatically assigns instances to the concepts and provides a good overview of the ontology to the user through concept browsing and various kind of visualization.
