Toward Bayesian Synchronous Tree Substitution Grammars for Sentence Planning
Proceedings of the 11th International Conference on Natural Language Generation, Association for Computational Linguistics, pp. 391-396, Tilburg, The Netherlands, 2018.
Developing conventional natural language generation systems requires extensive attention from human experts in order to craft complex sets of sentence planning rules. We propose a Bayesian nonparametric approach to learn sentence planning rules by inducing synchronous tree substitution grammars for pairs of text plans and morphosyntactically-specified dependency trees. Our system is able to learn rules which can be used to generate novel texts after training on small datasets.
