We present an original system for locating and removing personally-identifying information in patient records. In this experiment, anonymization is seen as a particular case of knowledge extraction. We use natural language processing tools provided by the MEDTAG framework: a semantic lexicon specialized in medicine, and a toolkit for word-sense and(More)
In this paper we describe the construction of a part-of-speech tagger both for medical document retrieval purposes and XP extraction. Therefore we have designed a double system: for retrieval purposes, we rely on a rule-based architecture , called minimal commitment, which is likely to be completed by a data-driven tool (HMM) when full disambiguation is(More)
Anticipatory postural adjustments (APAs) prior to step execution are thought to be immutable once released. Here we challenge this assumption by testing whether APAs can be modified online if a body perturbation occurs during execution. Two directions of perturbation (resisting and assisting) relative to the body weight transfer were used during the(More)
The main purpose of this study was to identify whether a lot of sports training had any effect on the balance control associated with a leg movement. The nature of the training experience was also an important concern and we chose subject who had undergone specific training experience in absence of equilibrium constraints. To this end a comparison between(More)
This article describes a set of initiatives in the domain if electronic dictionary distribution. Their basis is the DicoPro server, which enables secure access to dictionary data on a server. In the DicoEast and RERO projects, the goal is to acquire high-quality publisher data, convert it into numeric format, and provide access to dictionary entries for the(More)
Pressure fluctuations measured at the wall of a turbulent boundary layer are analysed using a bi-variate continuous wavelet transform. Cross-wavelet analyses of pressure signals obtained from microphone pairs are performed and a novel post-processing technique aimed at selecting events with strong local-in-time coherence is applied. Probability density(More)
A usual first principle in planning radioastronomy observations is that monitoring must be carried out well above the ionospheric plasma cutoff frequency (~5 MHz). Before space probes existed, radioastronomy was almost entirely done above 6 MHz, and this value is considered a practical lower limit by most radioastronomers. Furthermore, daytime ionization(More)
