We consider diierent methods of optimizing the classiication process of terminological representation systems, and evaluate their eeect on three diierent types of test data. Though these techniques can probably be found in many existing systems, until now there has been no coherent description of these techniques and their impact on the performance of a(More)
W. Wahlster, E. André, W. Finkler, H.-J. Profitlich and T. Rist, Plan-based integration of natural language and graphics generation, Artificial Intelligence 63 (1993) 387-427. Multimodal interfaces combining natural language and graphics take advantage of both the individual strength of each communication mode and the fact that several modes can be employed(More)
The family of terminological representation systems has its roots in the representation system kl-one. Since the development of this system more than a dozen similar representation systems have been developed by various research groups. These systems vary along a number of dimensions. In this paper, we present the results of an empirical analysis of six(More)
We consider different methods of optimizing the classification process of terminological representation systems and evaluate their effect on three different types of test data. Though these techniques can probably be found in many existing systems, until now there has been no coherent description of these techniques and their impact on the performance of a(More)
This work focusses on our first integration steps of complex and partly unstructured medical data into a clinical research database. Our main application is an integrated facetted search tool in nephrology based on automatic information extraction results from textual documents. We describe the details of our technical architecture which is based on(More)
This work focuses on the integration of multifaceted extensive data sets (e.g. laboratory values, vital data, medications) and partly unstructured medical data such as discharge letters, diagnostic reports, clinical notes etc. in a research database.
