- This work aims at constructing a simple and yet descriptively adequate grammar that best suits a semantic program based on situation theory. For this we propose an extended version of categorial grammar called ECG consisting of feature-based categories and operations of category cancellation. We demonstrate that this version can successfully account for such phenomena as agreement, case, and unbounded dependency in English. We also show that the use of indices in ECG makes it possible to adopt an equational approach to the representation and unification of information contents and thus to obta in the content of a complex experession by solving equations that represent the contents of its constitutent expressions. We, however, understand our proposed grammar ECG as an amalgamation , a successful amalgamation of current linguitic models such as GPSG, HPSG, and some version of categorial grammar.
