The Representation of Motion
The representation of motion begins by discussing motion‐oriented extensions of the spatial calculi described in Chapter 3, including models of relative motion. It then describes a relatively new semantics for motion in language, based on Dynamic Interval Temporal Logic (DITL), where constructing meaning involves creating an executable program. The authors show how the compositional semantics for motion expressions discussed in Chapter 2 can be recast more formally in DITL, with the spatial primitives used now grounded in terms of primitives drawn from these qualitative calculi. The chapter then elaborates the motion verb classification in Chapter 2, with DITL motion expressions for each class. The authors argue that their treatment addresses most of the requirements specified at the beginning of the book.
