Most information in Hospitals is still only available in text format and the amount of this data is immensely increasing. Consequently, text mining is an essential area of medical informatics. With the aid of statistic and linguistic procedures, text mining software attempts to dig out (mine) information from plain text. The aim is to transform data into(More)
Dieser Artikel beschreibt einige Erfahrungen und typische Problemstellungen mit Textmining in der Medizin und gibt einen Einblick in aktuelle und zukünftige Herausforderungen in Forschung & Entwicklung. Interessant ist nämlich, dass auch im ,,Multimedia-Zeitalter“ die meiste Information immer noch als ,,Text“ vorliegt. Mithilfe von statistischen und(More)
Although we live in the age of multimedia, most information is still only available in text format. This is especially true in medical informatics. Consequently, research in text mining is an essential area of computer science. With the aid of statistic and linguistic procedures, text mining software attempts to dig out (mine) information from plain text.(More)
Due to the increasing amount of medical patient data collected in hospitals, technology-based methods are of increasing interest for processing and analyzing such materials. Therefore, computer supported techniques have to be evaluated by means of their efficiency for this application area. In this paper, we introduce an approach for analyzing expert(More)
Experience shows that within the sensitive area of documentation in a clinical centre, there are problems involved in acquiring the end user's acceptance of authentication solutions based on smart cards, passwords, finger prints or digital signatures. The individual signature is still the most accepted method of certifying medical documents in hospitals and(More)
During the evaluation of Information Retrieval Algorithms, measurements are often made against a Gold Standard. Since the construction of such a Gold Standard requires considerable resources, a high validity and a high degree of reusability would be an advantage. From a scientific point of view, a high comparability between different Gold Standards would be(More)
