影视多媒体素材在英语听力教学中有着无可比拟的优势。随着网络资源信息量呈几何级数爆炸式增长,对信息进行有效过滤以便准确地找到用户感兴趣的素材显得尤为重要。在英语听力教学过程中,对多媒体信息的检索主要集中在低抽象语义层,即多数用户在搜索音频视频素材时都以台词内容作为检索关键字。针对这种状况,本文提出一种用于英语专业听力教学的具有数据收集、管理及应用功能的音频视频数据库系统的建设与管理方案。
Film and television multimedia materials have unparalleled advantages in English listening teaching. With the exponential growth of the amount of information on the network resources, it is particularly important to effectively filter information in order to accurately find the material that the user is interested in. In the English listening teaching process, the retrieval of multimedia information is mainly concentrated in the low abstract semantic layer, that is, most users use the content of the lines as the search key when searching audio and video materials. In view of this situation, this paper proposes a program for the construction and management of audio and video database system with data collection, management and application functions for English professional listening teaching.
