Semantic annotation for the “on demand graphical representation” of variable data in Web documents
Nour ElHouda Ben Chaabene, Ramzi Guetari · 2016
Visualization is the process of representing data graphically and interacting with these representations in order to gain insight into the data and to assist human information processing by reducing demands on attention, working memory, and long-term memory. The graphical representation of data is also used in the Web as a mean which carries visual and easy to understand information. However, graphics used to be static images that are not always up-to-date compared to the data it should represent. It therefore seems obvious that the best way to be faithful to reality is to build the graphical representation of the dynamically and on demand. In this paper we present an approach allowing to generate graphical representation of data in Web documents dynamically and on demand. The annotation, based on the Resource Description Framework, allows end users to ask for a graphical representation any time they want. This representation is built according to the data existing in the document. This is very convenient, especially if the Web document is a forum in which users express opinions; or any other Web document containing variable data and where the data changes very often.
