This paper presents some requirements for a new ontology-based authoring environment. By analyzing some systems that use ontologies for several tasks, we identified some features and purposes and showed how they can contribute to help define a new authoring environment based on ontologies to represent information before a document is published. The systems analysed fulfil specific tasks such as semantic annotation, visualization, document review and argumentation, information extraction and text engineering. By identifying some key features, it was clear that none of the tools could deliver the solution as a whole, but the integration of similar purpose tools into an interoperable environment can be a great contribution to ontology-based authoring environments. Even though Semantic Web technologies have revealed a trend in the use of ontologies for information processing, yet substantial work needs to be done to gather these initiatives in order to build an interoperable new authoring environment that takes advantage of present and new technologies.
