Improving Browser History using Semantic Information

Revisiting web pages is part of the routine of web browser users, yet the use of tools designed specifically for this function is not widespread. In this paper we describe a browser extension called ”Rdfa History” that attempts to improve the usefulness of the browser’s history list by enhancing it with semantic information (in RDFa format) gathered from previously visited pages. The collected semantic information provides a richer pool of information than the traditional time/url/title fields provided by browsers, allowing users to perform queries not only by keywords but also by particular topics or entities that appear on previously visited pages. This extension brings to user’s attention the usually invisible semantic web, and can be used both as tool that aids to revisit pages as well as a tool that helps to discover new pages related with the ones previously visited. It can also be used as a digital preservation tool that users can configure to collect and store history lists in a personal digital repository in order to access them from different browsers or devices, as well as use the history list as context provider for other documents that they might collect.
