A university's repository usually contains hundreds of such lecture videos. Each lecture video is typically an hour's duration and is often monolithic. It is cumbersome for students to search through an entire video, or across many videos, in order to find portions of their immediate interest. It is desirable to have a system that takes user-given keywords as a query and provides a link to not only the corresponding lecture videos but also to the section within the video. In order to do this, lecture videos are sometimes tagged with meta-data to enable easy identification of the different sections. However, such tagging is often done manually and is a time-consuming process. In this paper, we propose a technique to automatically generate tags for lecture videos. This is based on generating speech transcripts automatically using a speech recognition engine and automatic indexing and search of the transcripts. We also describe our system implemented for easily browsing through a lecture video repository. Our system takes keywords from users as a query and returns a list of videos as the results. In each video of the retrieved list, the portion of the video that matches the query is highlighted so that users can easily navigate to that location within the video. Following the approach and using open source tools mentioned in the paper, a lecture video repository can provide features for users to access the content required by them easily. We used open source libraries available for speech recognition and text search purposes. We have performed experiments to test the performance of our system, we have achieved a recall of 0.72 and an average precision of 0.84 as video retrieval results.","PeriodicalId":162825,"journal":{"name":"2011 IEEE International Conference on Technology for Education","volume":"15 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132411160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sustaining this growth requires technically trained professionals in large number. It requires providing education and training to population in increasing number. The technological advancement can be of great help in this regard. This paper studies and evaluates Technology Enhanced learning, with particular reference to NPTEL -- a portal dedicated to technical e-content -- across eight different Engineering Colleges of India located in Gujarat. Based on a comprehensive survey conducted across the Engineering Colleges with over 850 respondents, this study is a quantitative analysis of the findings and preferences articulated by students and faculty members. The questions pertain to the use and features of e content such as NPTEL used by students. Questions related to faculty quality, need for online educational services, content, technologies, pedagogies, research and extension are also posed to the sample. The responses of 287 NPTEL users out of the 875 respondents are compared across gender, institution, income level and such other factors. The responses are also tested for hypothesis analyses and other analysis such as factor analysis etc. The results and findings of the paper can be of use for further modifications and modeling of NPTEL for phase II.","PeriodicalId":162825,"journal":{"name":"2011 IEEE International Conference on Technology for Education","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123943472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
