An information visualisation system for the understanding of web data

Internet has become one of the best communication and marketing tools. Hence, designing well-structured Web sites with the information or products that users look for is a crucial mission. For this reason, understanding Web data is a decisive task to assure the success of a Website. In that sense, data mining techniques provide many metrics and statistics useful to automatically discover the structure, contents and usage of a site. This research aims at proving the usefulness of a set of information visualisation techniques in order to analyse Web data, using a visual Web mining tool that allows the combination, coordination and exploration of visualisations to get insight on Web data. The tool, named WET, provides a set of visual metaphors that represent the structure of the Websites where Web metrics are overlaid.
