Extending semantic browser style specifications for Semantic Web inferencing

Student thesis: Master's Thesis


This thesis proposes patterns of use for semantic browser interface specifications for inferred data using the Fresnel semantic browser style language. We also propose our own extension called Fresnel Inferences. The use of style for the presentation of inferencing, independent of other styles for presentation, contributes to the flexibility, reusability and development of information systems. We map references to the user interface with style sheets, which can then be adapted by an administrator to specific business needs through inferencing of display classes. This research proposes both use of current and extensions to form-based interface specifications for Fresnel to display presentation of inferencing results to end users in a human understandable way. Displaying the inferencing using styling and color in semantic browser as user interface components, the usability of Fresnel is further extended.
For this thesis Fresnel code is used for repeatability. Mockups show how a conforming browser with SMW as platform could implement it. In addition, it provides both the ability to make information of existing data available and form-based annotation interfaces to new data. The widely used rule-based fictional case of a car rental company EU-Rent is used as a demonstration how the mapping can be applied.
