Semantic Annotation is a basic technology for intelli-gent content and is beneficial in a wide range of content-oriented intelligent applications. In this paper we present our work in ontology-based semantic annotation, which is embedded in a scenario of a knowledge portal appli-cation. Starting with seemingly good and bad manual semantic annotation, we describe our experiences made within the KA2-initiative. The experiences gave us the starting point for developing an ergonomic and knowl-edge base-supported annotation tool. Furthermore, the annotation tool described are currently extended with mechanisms for semi-automatic information-extraction based annotation. Supporting the evolving nature of semantic content we additionally describe our idea of evolving ontologies supporting semantic annotation.
