An In-Browser Collaborative System for Functional Annotations

In this work, we used the Web IndeX system, which converts words into hyperlinks in arbitrary Web pages, to implement a system for sharing annotations registered on keywords within a limited group. This system allows group members to view all the written annotations by simply mousing over the keyword when it appears on a web page, facilitating sharing information and awareness in collaborative research and work. In this study, we define our system as a sticky note type annotation sharing system. In contrast to the sticky note type, our system is positioned as a functional type, but it may display annotations that are not necessary since it allows browsing on any page. To improve this point, we propose a usability judgment method that shows only the most useful posts.
