+  abstract = {Abstract\ \ A generic framework for the automated classification
+	of human movements using an accelerometry monitoring system is introduced.
+	The framework was structured around a binary decision tree in which
+	movements were divided into classes and subclasses at different hierarchical
+	levels. General distinctions between movements were applied in the
+	top levels, and successively more detailed subclassifications were
+	made in the lower levels of the tree. The structure was modular and
+	flexible: parts of the tree could be reordered, pruned or extended,
+	without the remainder of the tree being affected. This framework
+	was used to develop a classifier to identify basic movements from
+	the signals obtained from a single, waist-mounted triaxial accelerometer.
+	The movements were first divided into activity and rest. The activities
+	were classified as falls, walking, transition between postural orientations,
+	or other movement. The postural orientations during rest were classified
+	as sitting, standing or lying. In controlled laboratory studies in
+	which 26 normal, healthy subjects carried out a set of basic movements,
+	the sensitivity of every classification exceeded 87\%, and the specificity
+	exceeded 94\%; the overall accuracy of the system, measured as the
+	number of correct classifications across all levels of the hierarchy,
+	was a sensitivity of 97.7\% and a specificity of 98.7\% over a data
+	set of 1309 movements.},
