Bayesian Synchronous Tree-Substitution Grammar Induction and Its Application to Sentence Compression
13 years 8 months ago
We describe our experiments with training algorithms for tree-to-tree synchronous tree-substitution grammar (STSG) for monolingual translation tasks such as sentence compression a...
