This thesis is concerned with a presentation of <i>Classification-based Phrase STructure Grammar</i> (or CPSG), a grammatical theory that has grown out of extensive revisions of, and extension to, HPSG. The fundamental difference between this theory and HPSG concerns the central role that classification plays in the grammar: the grammar <i>classifies</i> strings, according to their feature structure descriptions, as being of various types. Apart from the role of classificaion, the theory bears a close resemblance to HPSG, though it is by no means a direct translation, including numerous revisions and extensions. A central goal in the development of the theory has been its computational implementation, which is included in the thesis. The second part concerns syntactic issues. In the third part, chapters 6, 7 and 8, we turn to semantic issues. The final part, Chapter 9, concerns the actual computational implementation of theory. A concluding chapter summarises the arguments of the thesis and outlines some avenues for future research.
