Kompletný popis

Propositionalization is a process that leads from relationaldata and background knowledge to a single-table representationthereof, which serves as the input to widespread systems for knowledge discovery in databases. Systems for propositionalization thus support the analyst during the usually costly phase of data preparation for data mining. We present a framework that allows for a unified description of approaches to propositionalization. Withinour framework, we systematically enhance existing approaches with techniques well-known in the area of relational databases, especially the application of aggregate functions. Further, we suggest special database schema transformations for efficiency reasons. We put special emphasis on empirical investigations into the spectrum of approaches. Data set sizes vary across different orders of magnitude, up to several million data points. Also, the domains are diverse, ranging from biological data sets to financialones, in order to demonstrate the broad applicability of propositionalization.
