nltk.app.srparser_app.ShiftReduceApp

class documentation

class ShiftReduceApp(object): (source)

Constructor: ShiftReduceApp(grammar, sent, trace)

View In Hierarchy

A graphical tool for exploring the shift-reduce parser. The tool displays the parser's stack and the remaining text, and allows the user to control the parser's operation. In particular, the user can shift tokens onto the stack, and can perform reductions on the top elements of the stack. A "step" button simply steps through the parsing process, performing the operations that nltk.parse.ShiftReduceParser would use.
