People have long been intrigued by the possibility of using a computer to understand natural language. Most researchers attempting to solve this problem have begun their efforts by trying to have the computer recognize the underlying syntactic form (the parse tree) of the sentence. This thesis presents an overview of the history of syntactic parsing of natural language, and it compares the major methods that have been used. Linguistically, two recent grammars are described: transformational grammar and systemic grammar. Computationally, three parsing strategies are described and compared: top-down parsing, bottom-up parsing, and a combination of both of these methods. Several important natural language systems are described, including Woods\u27 LUNAR program, Winograd\u27s SHRDLU, and Marcus\u27 PARSIFAL
