Smeagol: A "Specific-to-General" Semantic Web Query Interface Paradigm for Novices [chapter]

Aaron Clemmer, Stephen Davies
2011 Lecture Notes in Computer Science  
Most Semantic Web query interfaces let the user give an abstract specification of the desired results (perhaps using facets, or a natural language query.)  ...  We introduce the Smeagol visual query interface which, by contrast, guides the user from a specific example to a general result set.  ...  More advanced syntax was not necessary for the initial validation of the specific-to-general query paradigm.  ...
