... Survey of Rule-Invocation Strategies This section surveys the fundamental rule-invocation strategies in context-flee chart parsing. 3 In a chart- parsing framework, different rule-invocation strate- ... empirically. The experiments clearly indicate that it is possible to significantly increase efficiency in chart parsing by fine-tuning the rule-invocation strategy. Fine-tuning however also requires ... being generated, though. 228 Kay (1982) is the principal source, providing a very general exposition of the control strategies and data structures involved in chart parsing. In con- sidering...
