Web1. @bngschmnd Earley parser works pretty much the same as CKY. When a prefix part of a RHS has been recognized, it stores that in the chart, and keeps back-pointers in some form to the the subcomponents it used to do the completion. It is essentially the completer that builds the tree (as I remember). WebThis procedure takes an Earley state as input and produces the Viterbi parse for the substring between k and i as output. (If the input state is not complete ( ), the result will be a partial parse tree with children missing from the root node.) Viterbi-parse( ): If , return a parse tree with root labeled X and no children.

This makes it easier to contain and hide the details of the algorithm. The EarleyParser class can be implemented in either of two ways. First, the class could be static.
