Time cues are ubiquitous in language and the ability to interpret them is essential for understanding events during discourse comprehension. Temporal markers that signal ongoing versus completed events, like the progressive and simple past tense, prompt distinct mental event representations. However, the detailed properties of ongoing event representations remain unexplored. Drawing from both t...

Technical limitations in image capturing usually impose defective, such as contrast degradation. There are different approaches to improve the contrast of an image. Among the exiting approaches, un-sharp masking is a popular method due to its simplicity in implementation and computation. There is an important parameter in un-sharp masking, named gain factor, which affects the quality of the enh...

Multimodal systems support people with different needs and different features during the interaction process making it more easy and natural. However naturalness can usually produce ambiguous interpretation. This paper discusses ambiguities in multimodal interaction proposing in particular two different examples of ambiguities: a) multimodal ambiguities produced combining un-ambiguous modal inf...

Giving to computers the ability to talk and understand a natural language conversation is a major field of research. We have developed the HALPIN (Hyperdialogue avec un Agent en Langage Proche de l’Interaction Naturelle) system to implement our multimodal conversational model for information retrieval. This dialogue-oriented interface allows the access to the INRIA's database (Institut National...

The purpose of this paper is to inquire into the relationship between persuasive definition and common knowledge (propositions generally accepted and not subject to dispute in a discussion). We interpret the gap between common knowledge and persuasive definition (PD) in terms of potential disagreements: PDs are conceived as implicit arguments to win a potential conflict. Persuasive definitions ...
