Development of a Learning Support System which Allows to Write and Share Annotations on Web Contents

这项工作改进了一个称为“可写Web”的系统，该系统允许用户直接在基于Web的材料上编写和共享标记和备忘录（注释）。改进后的系统比以前的系统更快地估计更新材料上注释的位置。该系统还提供了用户与其他用户通过附加在材料上的备忘录进行交流的功能，并对共享的注释进行整理，向用户展示有用的信息。

This work improves a system called as" Writable Web" which allows its users to write and share markers and memos(annotations) directly on Web-based materials. The improved system estimates the location of annotations on updated materials faster than the former system. The system also offers its users a function to communicate with other users on memos attached on the materials and to organize the shared annotations to show the users useful information.
