PPT-Lexical and Syntactic Analysis

We look at two of the tasks involved in the compilation process break the source code into lexemes units lexical analysis the goal is to identify each lexeme and assign it to its proper token. org Abstract This paper presents a graphtheoretic model of the acquisition of lexical syntactic representa tions The representations the model learns are noncategorical or graded We propose a new evaluation methodology of syntactic ac quisition in th Albert Gatt.
