The evaluation of conversational dialog systems has remained a controversial topic, as it is challenging to quantitatively assess how well a conversation agent performs, or how much better one is compared to another. Furthermore, one of the hurdles which remains elusive in this quandary is the definition of naturalness, as demonstrated by how well a dialog system can maintain a natural conversation...
Emotion-aware applications supporting natural interaction are currently still a vision. One difficulty in developing these applications is the lack of multimodal corpora suitable for multiple use contexts, such as public spaces. Here, we introduce ElectroEmotion, a research tool prototype for collecting vocal and gestural corpora in novel contexts collaboratively. ElectroEmotion concept includes a...
With the massive use of the Web, numerous sites proposing exercises have appeared. The great difficulty for teachers and students is to find suitable exercises for the discovery of a new subject, training, revision or evaluation. On the basis of the teachers' reflections, on how they determine the exercises which they need, we extracted the characteristics which seemed to us the most important and...
As computers and software applications become ubiquitous the systems we build are increasingly required to run on not just a single piece of hardware, but rather be available for different platforms, different types of hardware and offer different modes of interaction depending on the context of use. Within a formal development process when we consider refinement for interactive systems we therefore...
In this paper, we describe the semantic content, which can be automatically generated, for the design of advanced dialog systems. Since the latter will be based on machine learning approaches, we created training data by annotating a corpus with the needed content. Given a sentence of our transcribed corpus, domain concepts and other linguistic levels ranging from basic ones, i.e. part-of-speech tagging...
