Lowering the Interactive Cost Of Tagging Systems: SparTag.us and Click2Tag:

SparTag.us and Click2Tags: Lowering the Interactive Cost Of Tagging Systems

Tagging systems such as del.icio.us and Diigo have become important ways for users to organize information gathered from the Web. However, despite their popularity among early adopters, tagging still incurs a relatively high interaction cost for the general users.

To understand the costs of tagging, for each of these systems, we performed a GOMS-like analysis of the interface and identified the overall number of steps involved in tagging. We count these steps to get a gross measure of the tagging costs ... [snip]

We introduce a new tagging system called SparTag.us, which uses an intuitive Click2Tag technique to provide in situ, low cost tagging of web content. In SparTag.us, we bring the tagging capability into the same browser window displaying the web page being read. When a user loads a web page in his browser, we augment the HTML page with AJAX code to make the paragraphs of the web pages as well as the words of the paragraphs live and clickable.

As users read a paragraph, they can simply click on any words in the paragraph to tag it. SparTag.us also lets users highlight text snippets and automatically collects tagged or highlighted paragraphs into a system-created notebook, which can be later browsed and searched. We're currently conducting an internal PARC beta-testing of this tool, and hope to release it for public use in the near future.
