Most of the current methodologies for building ontologies rely on specialized knowledge engineers. 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.

We revisit the top-level ontology Gumo for the uniform management of user and context models in a semantic web environment. We discuss design decisions, while putting the focus on ontological issues. The structural integration into user model servers, especially into the U2M-UserModel&ContextService, is also presented. We show ubiquitous applications using the user model ontology Gumo together with the user model markup language UserML. Finally, we ask how data from Web 2.0 and especially from a social tagging application like del.icio.us as a basis for user adaptation and context-awareness could influence the ontology

The Age of Image predates and is currently contemporaneous with the Information Age. In our times the explosive expansion of Web 2.0 Social Space, typified by the phenomena of De.licio.us, Flickr, MySpace, YouTube…, and the concomitant emergence of folksonomy, present interesting challenges in the management of this information. One key process by which to accomplish this in Social Space, is the wedding of folksonomy (of the people) with ontology (of the machine). Such a wedding must necessarily be conducted in the shared physicality of the word, of language. In this respect, WordNet together with OWL, play the role of matchmaker. But the same Social Space also provides an opportunity for natural folksonomical tagging by digiFoto (key)image.
