High Interactive Web-Annotation Based E-learning Platform

This paper aims to develop a multi-user Web Content Annotation System by ways of a tree structure to facilitate in-depth discussion. Apart from annotating systems like hand written notes and labeling stickers, learners can focus on specific topics or terminologies, publish (answers) questions or opinions, initiate discussions on annotations made by others, and make re-annotations through a tree structure to a further discussion. Contents of discussion are presented in webpage form. Knowledge providers therefore could make extensions on current curriculum or topics. Learners, along with other users, are able to acquire more in-depth readings and further annotations. From such in-depth discussions of specific topics or terminologies, collaborative online learning is reinforced.
