Chart Generation
نویسنده
چکیده
Charts constitute a natural uniform architecture for parsing and generation provided string position is replaced by a notion more appropriate to logical forms and that measures are taken to curtail generation paths containing semantically incomplete phrases.

Chart Generation Using Production Systems
Productions systems, traditionally mainly used for developing expert systems, can also be employed for implementing chart generators. Focusing on bottom-up chart generation, we describe how the notions of chart algorithms relate to the knowledge base and Rete network of production systems. We draw on experience gained in two research projects on natural language generation (NLG), one involving ...
متن کاملAn Efficient Chart Generator for (Semi-)Lexicalist Grammars
We describe a generator for rule-based grammars which are primarily lexicalist but may introduce some semantics via constructions. By combining chart generation with a treatment of modification by adjunction, we obtain substantial performance improvements over standard lexically-driven chart-generation.

متن کاملGeneration of Paraphrases from Ambiguous Logical Forms
This paper presents a method for generating multiple paraphrases from ambiguous logical forms. The method is based on a chart structure with edges indexed on semantic information and annotations that relate edges to the semantic facts they express. These annotations consist of logical expressions that identify particular realizations encoded in the chart. The method allows simultaneous generati...
متن کاملIntegrated sentence generation with charts
Integrating surface realization and the generation of referring expressions (REs) into a single algorithm can improve the quality of the generated sentences. Existing algorithms for doing this, such as SPUD and CRISP, are search-based and can be slow or incomplete. We offer a chart-based algorithm for integrated sentence generation which supports efficient search through chart pruning.
