Experimenting with the interaction between aggregation and text structuring

摘要

In natural language generation, different generation tasks often interact with each other in a complex way, which is hard to capture in the pipeline architecture described by Reiter (Reiter, 1994). This paper focuses on the interaction between a specific type of aggregation and text planning, in particular, maintaining local coherence, and tries to explore what preferences exist among the factors related to the two tasks. The evaluation result shows that it is these preferences that decide the quality of the generated text and capturing them properly in a generation system could lead to coherent text.
