基于Web的多媒体新闻语料库的建设与实施——以听力教学与研究为目的的设计模型

Web-based Multimedia News Corpus Construction Methods and Its Application in Listening Class

Web多媒体或多模态语料库作为第四代语料库，其建设与研究已成为研究热点。多媒体语料库具有文本、声音、视频等多种媒体共存、关联、互动的特点和优势，非常适合应用于英语听力教学实践。建立为听力教学服务的Web多媒体语料库除需要有丰富的多媒体数据库，确定语料库结构，并按照一定的标准进行格式化入库等常规建库操作之外，还需设计适于听力教学的辅助功能，如在线练习自动生成，词汇难度列表，语料可读性分析、听力新闻专有名词提取等。具备教学功能的Web多媒体语料库，使语料库教学实施更具灵活性、广适性和可操作性，有利于学习者利用语料库进行移动学习、自主学习和研究性学习，提高英语听力教学效率和效果。
