Báo cáo khoa học: "STRATEGIES FOR ADDING CONTROL INFORMATION TO DECLARATIVE GRAMMARS" ppt

... Strategies are proposed for combining different kinds of constraints in declarative grammars with a detachable layer of control information. The added control information is the basis for parametrized ... several strategies for adding control information to the grammar without sacrificing its declarative nature. One of the central hypotheses of the paper is that-i...
