Designs and Prototype: Report IV on Knowledge-based Mining of Complex Event Patterns ; Semantic Pattern Mining in Event Streams

Abstract

In this report, we present our research results for the fourth half-year phase of the project Corporate Smart Content under the working package "Knowledge- based Mining of Complex Event Patterns". We present SpaceROAM, our new approach to Role Discovery that focuses on the domain of Collaborative Content Management Systems. The method tries to magnify users' characteristic features by positioning them among other one of the same user as well as among features of other users. Applied on real-life data, the method was able to recognize all typical roles and to detect new ones that differ from the known ones significantly. Finally, we provide a description of other research tasks that we started and whose results will be included in our next report.
