- W3048897756 abstract "Recently, the popularity for massive online open course (MOOC) learning among student community is increasing day by day. In most of the MOOC learning Web sites, indexing and retrieval techniques are based on the keywords like names, titles and Web addresses of the videos. As a result, the response for content-based queries is not good in most of the scenarios. In this paper, we propose an efficient scene content-based indexing and retrieval (ESCIR) framework for lecture videos. The proposed ESCIR framework consists of two phases: offline phase and online phase. In offline phase, we apply novel block-level key frame extraction (BLKFE) technique to segment video frames into shots and choose the right frame. The optical character recognition (OCR) tool is applied to the generated key frames in the videos for extracting the text. The jaccard similarity coefficient measure is used to eliminate the duplicate text frames, and then use of stop word removal and stemming algorithms are applied to get meaningful keywords from the scene. We used single-pass in-memory indexing (SPIMI) technique for building the indexing with the help of extracted keywords. In online phase, search and matching algorithms will map input queries given by user to the corresponding videos. We applied the okapi BestMatch25 (BM25) ranking function to rank those matched videos for best relevance results. The proposed ESCIR framework has been validated on standard video lectures and found to give better results than the existing state of art algorithms in terms of precision and accuracy. We compared our results with existing methods of lecture video techniques reflects improvising robust performance on lecture videos." @default.
