Finite-state descriptions for temporal semantics are outlined through which to distinguish soft inferences reflecting manners of conceptualization from more robust semantic entailments defined over models. Just what descriptions are built (before being interpreted model-theoretically) and how they are grounded in models of reality explain (upon examination)(More)
Elementary ((rst-order) and non-elementary (set-theoretic) aspects of the largest bisimulation are considered , with a view towards analyzing operational semantics from the perspective of predicate logic. The notion of a bisimulation is employed in two distinct ways: (i) as an extensional notion of equivalence on programs (or processes) generalizing(More)
The notion of inertia is explicated in terms of forces recorded in snapshots that are strung together to represent events. The role inertia worlds were conceived to serve in the semantics of the progressive is assumed by a branching construct that specifies what may follow, apart from what follows.
Intervals and the events that occur in them are encoded as strings, elaborating on a conception of events as " intervals cum description. " Notions of satisfaction in interval temporal logics are formulated in terms of strings, and the possibility of computing these via finite-state machines/transducers is investigated. This opens up temporal semantics to(More)
Notions of disambiguation supporting a compositional interpretation of ambiguous expressions and reeecting intuitions about how sentences combine in discourse are investigated. Expressions are analyzed both inductively by breaking them apart, and co-inductively by embedding them within larger contexts.
