This paper shows how to reconcile epistemic invariantism with the knowledge account of assertion. My basic proposal is that we can comfortably combine invariantism with the knowledge account of assertion by endorsing contextualism about speech acts. My demonstration takes place against the backdrop of recent contextualist attempts to usurp the knowledge account of assertion, most notably Keith ...

We present an application independent dialogue engine that reasons on application dependent knowledge sources to calculate predictions about how a dialogue might continue. Predictions are language independent and are translated into language dependent structures for recognition and synthesis. Further, we discuss how the predictions account for di erent kinds of dialogue, e.g., question-answer o...

Today’s work is increasingly characterized by unpredictable collaborative processes called knowledge work. Some types of knowledge work are supported by case management tools which typically provide regulated access to case-related information. Knowledge workers are well aware of the pragmatic dimension of their communicative acts, but the systems they are using currently are not. This demo pap...

We describe an integrated approach for statistical modeling of discourse structure for natural conversational speech. Our model is based on 42 ~dialog acts’ (e.g., Statement, Question, Backchannel, Agreement, Disagreement, Apology), which were hand-labeled in 1155 conversations from the Switchboard corpus of spontaneous human-to-human telephone speech. We developed several models and algorithms...
