Abstract
A new approach to ambiguity of context-free grammars is presented, and within this approach the LL and LR techniques are generalized to solve the following problems for large classes of ambiguous grammars:
The user may control the parser generation so as to get a parser which finds some specific parse trees for the sentences. The generalized LL and LR techniques will still guarantee that the resulting parser accepts all sentences and terminates in linear time on all input.
