Semantic Web user interfaces - A model and a review

At first a study of related literature is performed, and in it are identified and analyzed those distinctive characteristics that a user interface needs to support. Then, it is conducted a field research in the World Wide Web, in order to discover and record Semantic Web's user interfaces. Based on the analysis of the reviewed literature, the model is devised, and the model's formalism is applied to the findings of the field research. After that, it is conducted an evaluation study and with the help of a dedicated application, comparative tables are outlined for reviewing user interfaces.
