Roundup of Graphical Navigation Helpers on the Web (Report‪)‬

INTRODUCTION The web is an open space of information, dynamic, distributed, heterogeneous and non-moderated. One notes that on the Web, sites appear and disappear, content is modified and it becomes impossible to master their organization. In fact, the navigation process on the web is confronted by three major problems. On one hand, the nature of the environment itself imposes some disadvantages: Internet is a network of worldwide level, constantly changing and non-structured. Next, the navigator users generally have difficulties in constructing a mental navigation outline. At last, the computer-aided tools for navigation offered by different classical software do not satisfy the user needs and sometimes contribute, paradoxically, to make the navigation process more confusing(1). The conclusion from the analysis of these problems is to develop new computer aided tools for navigation. These tools will have to be able to address the following two main questions usually asked by the user: "which link to follow?" and "how to retrieve this page?". The Internet representation tools and the user navigation path visualization are certainly answers provided by the current and feature developments(2).
