摘要:

视频是在网络搜索期间学习中常用的内容类型。许多电子学习平台提供高质量的内容,但有时教育视频很长,涵盖许多主题。人类擅长从视频中提取重要部分,但这对计算机来说仍然是一个重大挑战。在本文中,我们解决的问题,分配的重要性分数的视频片段,这是多少信息,它们包含相对于整体主题的教育视频。我们提出了一个注释工具和一个新的数据集的注释教育视频收集流行的在线学习平台。此外,我们提出了一个多模态神经架构,利用国家的最先进的音频,视觉和文本功能。我们的实验研究视觉和时间信息的影响,以及多模态特征的组合对重要性预测。

英文摘要:

Videos are a commonly-used type of content in learning during Web search. Many e-learning platforms provide quality content, but sometimes educational videos are long and cover many topics. Humans are good in extracting important sections from videos, but it remains a significant challenge for computers. In this paper, we address the problem of assigning importance scores to video segments, that is how much information they contain with respect to the overall topic of an educational video. We present an annotation tool and a new dataset of annotated educational videos collected from popular online learning platforms. Moreover, we propose a multimodal neural architecture that utilizes state-of-the-art audio, visual and textual features. Our experiments investigate the impact of visual and temporal information, as well as the combination of multimodal features on importance prediction.
