In this paper, we report on classification results for emotional user states (4 classes, German database of children interacting with a pet robot). Starting with 5 emotion labels per word, we obtained chunks with different degrees of prototypicality. Six sites computed acoustic and linguistic features independently from each other. A total of 4232 features… (More)
BACKGROUND Many studies have suggested that cognitive training can result in cognitive gains in healthy older adults. We investigated whether personalized computerized cognitive training provides greater benefits than those obtained by playing conventional computer games. METHODS This was a randomized double-blind interventional study. Self-referred… (More)
Otoacoustic emissions (OAEs) are useful for studying medial olivocochlear (MOC) efferents, but several unresolved methodological issues cloud the interpretation of the data they produce. Most efferent assays use a "probe stimulus" to produce an OAE and an "elicitor stimulus" to evoke efferent activity and thereby change the OAE. However, little attention… (More)
In this paper, we report on classification results for emotional user states (4 classes, German database of children interacting with a pet robot). Six sites computed acoustic and linguistic features independently from each other, following in part different strategies. A total of 4244 features were pooled together and grouped into 12 low level descriptor… (More)
In this article, we describe and interpret a set of acoustic and linguistic features that characterise emotional/emotion-related user states – confined to the one database processed: four classes in a German corpus of children interacting with a pet robot. To this end, we collected a very large feature vector consisting of more than 4000 features extracted… (More)
Two psycholinguistic and psychophysical experiments show that in order to efficiently extract polarity of written texts such as customer-reviews on the Internet, one should concentrate computational efforts on messages in the final position of the text.
We developed a computerized neuropsychological assessment software, which employs innovative features in both the presentation of the tests and the interpretation of the subjects' performance. The usability features of the software enabled elderly subjects with no computer experience to undergo the cognitive tests, without a test administrator being… (More)
Emotions play a major role in human-to-human communication enabling people to express themselves beyond the verbal domain. In recent years, important advances have been made in unimodal speech and video emotion analysis where facial expression information and prosodic audio features are treated independently. The need however to combine the two modalities… (More)
