There has been huge progress in the introduction of new digital methods, such as decision support, in cardiology. Data preparation is the most important and the most time-consuming part of the data mining process. We present a newly developed hierarchical method of text classification based on regular expressions. This method is the basis of our data mining system during the preprocessing stage to transform Latin-based free-text medical reports into a decision table. In this study we also compare the accuracy and scalability of our method with an approach based on dictionary phrases. 1.
