问答篇章生成系统中的用户模型和文本规划

在问答生成系统中,如果系统首先了解用户对问题所涉及的领域知识的掌握程度,系统则能根据这些知识组织文本,生成符合用户需要的内容,更好地进行人机交互。本文以花卉知识查询系统为基础,探索了用户知识对生成结果的影响,以及用户模型与文本规划之间的相互作用。实验结果表明:用户知识模型不但影响生成的内容,而且影响生成内容的风格。在此系统中,我们采取两种基本生成策略:Schema方法和Process方法,并探讨这两种生成方法的相互结合过程。

User Modeling and Text Planning in a Question-answering Generation System

In a question answering system,if the system can get a view of the do main knowledge that the user masters,it can generate answers both informative and understandable to the user,which can make the interaction between human and computer better.Based on the flower knowledge retrieval system,this paper discusses the effect of the user model on the generated contents and the relationship between the user model and the text planner.Experiments show that the user model affects not only the generated contents but also the style of the generated contents.The generation system uses two generating strategies:schema and process.Combination of these two methods is also discussed in this paper.
