Bridging learning analytics and Cognitive Computing for Big Data classification in micro-learning video collections
پل تجزیه و تحلیل یادگیری و پردازش شناختی برای طبقه بندی داده های بزرگ در مجموعه های ویدئویی میکرو یادگیری-2018 Moving towards the next generation of personalized learning environments requires intelligent ap
proaches powered by analytics for advanced learning contexts with enriched digital content. Micro
Learning through Massive Open Online Courses is riding the wave of popularity as a novel paradigm
for delivering short educational videos in small pre-organized chunks over time, so that learners can get
knowledge in a manageable way. However, with the ever-increasing number of videos, it has become
challenging to arrange and search them according to specific categories. In this paper, we get around the
problem by bridging Learning Analytics and Cognitive Computing to analyze the content of large video
collections, going over traditional term-based methods. We propose an efficient and effective approach
to automatically classify a collection of educational videos on pre-existing categories which uses (i) a
Speech-to-Text tool to get video transcripts, (ii) Natural Language Processing and Cognitive Computing
methods to extract semantic concepts and keywords from video transcripts for their representation, and
(iii) Apache Spark as Big Data technology for scalability. Several classifiers are trained on the feature
vectors extracted by Cognitive Computing tools. Then, we compared our approach with other combi
nations of state-of-the-art feature types and classifiers over a large-scale dataset we collected from
Coursera. Considering the experimental results, we expect our approach can facilitate the development
of Learning Analytics tools powered by Cognitive Computing to support content managers on micro
learning video management while improving how learners search videos.
