This is in contrast to real-world settings, where the need for maintenance of domain specific ontologies emerges in the daily work of users. But in order to allow for participatory ontology engineering, we need to have a more realistic conceptual model of how ontologies develop in the real world. We introduce the ontology maturing processes which is based on the insight that ontology engineering is a collaborative informal learning process and for which we analyze characteristic evolution steps and triggers that have users engage in ontology engineering within their everyday work processes. This model integrates tagging and folksonomies with formal ontologies and shows maturing pathways between them. As implementations of this model, we present two case studies and the corresponding tools. The first is about image-based ontology engineering (introducing so-called imagenotions), the second about ontology-enabled social bookmarking (SOBOLEO). Both of them are inspired by lightweight Web 2.0 approaches and allow for realtime collaboration.Thu Sep 13 13:58:30 CEST 2007Berlin4th Conference on Professional Knowledge Management - Experiences and Visions, Workshop on Productive Knowledge Work (ProKW 07)March217-226Ontology Maturing with Lightweight Collaborative Ontology Editing Tools22007ipe fzi workshop aps lang:en soboleo professional_learning ontology ontology_maturing maturing ontology_engineering wissensnetz folksonomy from:aschmidt 28-30Ontology building is an important prerequisite for state-of-the-art semantic technologies for knowledge worker support. But ontology engineering methods have so far neglected the early phase of ontology building where a conceptualization only exists rather informally and underlies continuous evolution through collaboration and interaction within the community. We have to view ontology building as a maturing process that requires collaborative editing support and the integration into the daily work processes of knowledge workers. In spirit of current Web 2.0 applications, we present an AJAX-based lightweight ontology editor as a first approach to this problem.Thu Sep 13 13:56:55 CEST 2007MünchenMensch \& Computer - 7.

Derzeitige Werkzeuge gestatten entweder die Erstellung einer Ontologie oder die Strukturierung von Ressourcen entsprechend einer vorgegebenen, unveränderlichen Ontologie bzw. ganz ohne jegliche Struktur. In dieser Arbeit zeigen wir, wie sich kollaboratives Tagging und kollaborative Ontologieentwicklung vereinen lassen, so dass jeweilige Schwächen vermieden werden und die Stärken einander ergänzen. Wir präsentieren SOBOLEO, ein System, das kollaborativ und web-basiert die Erstellung, Erweiterung und Pflege von Ontologien und gemeinsamer Lesezeichensammlung ermöglicht und gleichzeitig die Annotierung von Internetressourcen mit Konzepten aus der erstellten Ontologie unterstützt.
