time, and meta-level reasoning in general [13]. Applications are to be found in the contexts of large-scale natural language processing architectures for texts (e.g., UIMA [14]), and dialogical interactions with the Semantic Web (e.g., SmartWeb
[15] integrating extensive ontological groundwork [16] for self-representation of an information state to be included into a metacognitive model). The metacognitive control and augmented Data Mining Cycle proposed here will be integrated into a new situation-aware dialogue shell for the Semantic Access to **Media and** Services in the near future—to handle, fore and foremost, the access to dynamic, heterogeneous information structures.
