In the last years business process mining has become a wide research area. However, existing process mining techniques encounter challenges while dealing with event logs stemming from highly flexible environments because such logs contain a large amount of different behaviors. As a result, inaccurate and wrong analysis results might be obtained. In this paper we propose a case (a case is an instance of the business process) classification technique which is able to combine domain experts knowledge for classifying cases so that each group is calculated containing the cases with similar behaviors. By applying existing process mining techniques on the cases for each group, more meaningful and accurate analysis results can be obtained.
We propose a lexicalized formulation of dependency grammar that addresses both immediate dependence and linear precedence. Our approach distinguishes two orthogonal, yet mutually constraining dependency trees: an ID t...

ETAPS 2000 was the third instance of the European Joint Conferences on Theory and Practice of Software. ETAPS is an annual federated conference that was established in 1998 by combining a number of existing and new conferences. This year it comprised ve conferences (FOSSACS, FASE, ESOP, CC, TACAS), ve satellite workshops (CBS, CMCS, CoFI, GRATRA, INT), seven invited lectures, a panel discussion, and ten tutorials. The events that comprise ETAPS address various aspects of the system de- lopment process, including speci cation, design, implementation, analysis, and improvement. The languages, methodologies, and tools which support these - tivities are all well within its scope. Di erent blends of theory and practice are represented, with an inclination towards theory with a practical motivation on one hand and soundly-based practice on the other. Many of the issues involved in software design apply to systems in general, including hardware systems, and the emphasis on software is not intended to be exclusive.
We present an adaptation of input/output conformance (ioco) testing principles to families of similar implementation variants as appearing in product line engineering. Our proposed product line testing theory relies o...

Hardware trends suggest that large-scale CMP architectures, with tens to hundreds of processing cores on a single piece of silicon, are iminent within the next decade. While existing CMP machines have traditionally been handled in the same way as SMPs, this magnitude of parallelism introduces several fundamental challenges at the architectural level and this, in turn, translates to novel challenges in the design of the software stack for these platforms. This paper presents the "Many Core Run Time" (McRT), a software prototype of an integrated language runtime that was designed to explore configurations of the software stack for enabling performance and scalability on large scale CMP platforms. This paper presents the architecture of McRT and discusses our experiences with the system, including experimental evaluation that lead to several interesting, non-intuitive findings, providing key insights about the structure of the system stack at this scale. A key contribution of this paper is to demonstrate how McRT enables near linear improvements in performance and scalability for desktop workloads such as the popular XviD encoder and a set of RMS (recognition, mining, and synthesis) applications. Another key contribution of this work is its use of McRT to explore non-traditional system configurations such as a light-weight executive in which McRT runs on "bare metal" and replaces the traditional OS. Such configurations are becoming an increasingly attractive alternative to leverage heterogeneous computing uints as seen in today's CPU-GPU configurations. Copyright 2007 ACM.
