We present a description of an enterprise expert search system which is based on the analysis of content and communications topology in an enterprise information space. As data sources we use the collections introduced at the Text Retrieval Conference (TREC) in 2006 and 2007. An optimal set of weighting coefficients for three query-candidate associating algorithms is selected for achieving the best search efficiency on a specified corpus. The obtained performance proved to be better than at most TREC participants.
Process mining is a research area dealing with, inter alia, the construction of models of various types from event logs. Fuzzy maps are an example of such models produced by different process mining tools, such as ProM and Disco. We proposed a new approach to mining fuzzy models which is based on logs representation in the form of relation databases. Fast and effective SQL queries to such logs are made as a part of a DPMine workflow model. Resulting datasets are processed and visualized by a special DPMine component working tightly integrated with VTMine modeling framework. The paper discusses the suggested approach in the context of customization aspects of VTMine framework with an embedded DPM engine.
