Linking and Maintaining Quality of Data about MOOCs Using Semantic Computing

Emergence of Linked Data has made it possible to make sense of huge data that is scattered all over the web, and link data from multiple heterogeneous sources. This leads to the challenge of maintaining the quality and integrity of Linked Data, i.e., ensuring outdated data is removed and latest data is included. The focus of this paper is devising strategies to effectively integrate data from multiple sources, publish it as Linked Data, and maintain the quality of Linked Data. The domain used in the study is online education. We present the integration of data from various MOOC providers and algorithms for incrementally updating linked data to maintain their quality in order to constantly keep the users engaged with up-to-date data. Experimental results of the evaluation of the algorithms are presented.
