A more consequential issue in computational semantics has been the expressivity of the semantic representation employed, with respect to phenomena such as event and temporal reference, nonstandard quantifiers such as most,  plurals, modification, modality and other forms of intensionality, and reification. Full discussion of these phenomena would be out of place here, but some commentary on each is warranted, since the process of semantic interpretation and understanding (as well as generation) clearly depends on the expressive devices available in the semantic representation.
