People reason about possibilities routinely, and reasoners can infer “modal” conclusions, i.e., conclusions that concern what is possible or necessary, from premises that make no mention of modality. For instance, given that Cullen was born in New York or Kentucky, it is intuitive to infer that it’s possible that Cullen was born in New York, and a recent set of studies on modal reasoning bear o...

The MISTRAL system, a service oriented architecture for semantic extraction of multimedia data from meeting recordings is described shortly. It improves on other similar systems by extracting a variety of semantic metadata from one media type and integrating it with concepts derived from other media types, as well as by adding inference capabilities to resolve ambiguities and further enrich ext...

This study investigates expressions of propositional modality (epistemic and evidential) in Japanese and Chinese. It aims to highlight some fundamental characteristics of and differences between the modal systems in the two languages. It has been found that adverbs in Chinese play a more important role than adverbs in Japanese in expressing modal meanings. This study has also found that more mo...

This paper examined disagreement in two sets of data in the context of service encounters: problem-solving interactions (doctor-patient communication) and purchase-oriented encounters (pharmacies) from a cross-cultural perspective (Spanish-British English). We proposed assertiveness, a term that refers to both socio-psychological and linguistic features of communication, as a concept that may h...

We present two models of hierarchical structured multi-agents, and we describe how to obtain a modal knowledge base from distributed sources. We then propose a computationally oriented revision procedure for modal knowledge bases. This procedure is based on a labelled tableaux calculi supplemented with a formalism to record the dependencies of the formulae. The dependencies are then used to rec...
