WebA branch of computer science research called formal language theory that also has its origins in the work of Chomsky [1959], is devoted to determining which sets of strings of words can be generated by different classes of grammars. Tree-adjoining grammars can generate some languages that context-free grammars cannot. WebIn analyzing linguistic structure, Chomsky came up with a variety of systems for describing a language, which have proven especially important to computer science. In this chapter, we'll study one of the most important such systems, context-free grammars. (Chomsky called them phrase structure grammars, but computer scientists prefer their own ...
