Towards Flexible, Small-Domain Surface Generation: Combining Data-Driven and Grammatical Approaches
Proceedings of the 15th European Workshop on Natural Language Generation (ENLG), Association for Computational Linguistics, pp. 105-108, Brighton, England, UK, 2015.
As dialog systems are getting more and more ubiquitous, there is an increasing number of application domains for natural language generation, and generation objectives are getting more diverse (e.g., generating informationally dense vs. less complex utterances, as a function of target user and usage situation). Flexible generation is difficult and labourintensive with traditional template-based generation systems, while fully data-driven approaches may lead to less grammatical output, particularly if the measures used for generation objectives are correlated with measures of grammaticality. We here explore the combination of a data-driven approach with two very simple automatic grammar induction methods, basing its implementation on OpenCCG.
