ReCa: A Social Relationship Mining Tool in Virtual Learning Environment

Abstract

This paper provides an introduction to a membersâ?? Relationship Calculation Tool (ReCa) of Sakai platform and a brief discussion of its design research process. Learning Management Systems (LMSs) usually gather a range of usersâ?? performance log, which can be used in educational data mining in different perspectives, including social relationship exploration. However, data mining approach usually consumes a lot of manual work and requires database search skills. There is still no effective tool for instructors to find out participantsâ?? social relationship in online learning community. The main objective of ReCa design is to fill the gap by easily carrying out participantsâ?? social relationship matrix in Sakai platform.
