汉语教学用话题库及话题分类影视资源库构建

On Constructing a Topic Bank and a Topic-Oriented Video Resource Library for Chinese Teaching

本研究在大规模汉语教学语料库的基础上,构建了一个含5大类、35个话题及54个子话题的话题库,并按常用度排序;以此话题库为纲,截取热门影视剧中相关度高的字幕文本和视频片段,构建按话题对应的影视对话片段库及其对应的影视频资源库;对各个片段标注场景,按照会话片段与话题的相关程度及片段常用度进行排序分级,方便辅助不同层次的汉语教学。

On the basis of large-scale Chinese teaching corpora, a topic bank consisting of five categories, 35 topics and 54 sub-topics is established and sorted according to the frequency of occurrence. Then a topic-oriented video resource library is set up by intercepting highly relevant video clips from popular movies and TV programs while maintaining the subtitles. Each video clip is labeled and sorted by its relevance to the topic and likelihood of occurrence with a view to facilitating Chinese teaching at different levels.
