- PublicationAccès libreCrime Linkage: a Fuzzy MCDM Approach(: IEEE, 2013-6-4)
; ; ;Grossrieder, Lionel ;Ribaux, OlivierGrouping crimes having similarities has always been interesting for analysts. Actually, when a set of crimes share common properties, the capability to conduct reasoning and the automation with this set drastically increase. Conjunction, interpretation and explanation based on similarities can be key success factors to apprehend criminals. In this paper, we present a computerized method for high-volume crime linkage, based on a fuzzy MCDM approach in order to combine situational, behavioral, and forensic information. Experiments are conducted with series in burglaries from real data and compared to expert results.

;Grassi, Sara ;Heck, P. ;Stadelmann, Patrick ; ;Dinissen, P. ;Meylan, F. ;Mignot, J.-P. ;Pfeuti, J.-N. ;Piccini, F. ;Geiser, P. ;Biundo, Giuseppina ;Farine, Pierre-André ;Grupp, JoachimThis paper describes the development of a voice data recording watch and the accompanying software and hardware needed to build an integrated solution for medical data capture and auto-matic codification. The developed system is used to capture on the stand-alone watch, either by voice recording or by form-filling, the relevant information on the healthcare service being provided. The captured information is stored locally and then downloaded to a PC, via a USB connection. In the PC, speech is translated first into text and then into medical codification, with minimum user-intervention. The resulting information is stored into local or cen-tralized patient databases, to be sent later to 3rd-party SW for billing, reporting and statistics. The user controls the watch either via a touch-screen based interface or via a voice-driven interface for hands-free operation. Although this work is multidisciplinary, in this paper the emphasis is put on the description of the DSP implementation.

- PublicationMétadonnées seulementFirst-Order Logic Based Formalism for Temporal Data Mining(Berlin: Springer-Verlag, 2005)
;In this article we define a formalism for a methodology that has as purpose the discovery of knowledge, represented in the form of general Horn clauses, inferred from databases with a temporal dimension. To obtain what we called temporal rules, a discretisation phase that extracts events from raw data is applied first, followed by an induction phase, which constructs classification trees from these events. The theoretical framework we proposed, based on first-order temporal logic, permits us to define the main notions (event, temporal rule, constraint) in a formal way. The concept of consistent linear time structure allows us to introduce the notions of general interpretation and of confidence. These notions open the possibility to use statistical approaches in the design of algorithms for inferring higher order temporal rules, denoted temporal meta-rules.

- PublicationMétadonnées seulementBusiness process modelling for academic virtual organizations(Boston: Springer, 2008)
;The increasing mobility due to Bologna process forces the academic partners to increase the inter-operability of their administrative processes, by interacting through a collaborative networks and therefore acting as an academic virtual organization. To facilitate the communication and the comprehension of the administrative processes between the components of the CN, the Business Process Modelling Notation (BPMN) is proposed in this paper as a standard graphical model for administrative processes and transactions. The adaptability of this standard for academic processes and the difficulties of "translating" the actual administrative models (legal texts) in BPMN diagrams are analysed.

- PublicationMétadonnées seulementTime Granularity in Temporal Data Mining(Berlin: Springer Verlag, 2009)In this chapter, a formalism for a specific temporal data mining task (the discovery of rules, inferred from databases of events having a temporal dimension), is defined. The proposed theoretical framework, based on first-order temporal logic, allows the definition of the main notions (event, temporal rule, confidence) in a formal way. This formalism is then extended to include the notion of temporal granularity and a detailed study is made to investigate the formal relationships between the support measures of the same event in linear time structures with different granularities. Finally, based on the concept of consistency, a strong result concerning the independence of the confidence measure for a temporal rule, over the worlds with different granularities, is proved.
