Abstract
Techniques to retrieve, rank and display data objects retrieved form a database are described. In particular, methods to assign a global ranking value to a data object based on a combination of that object's link-based (e.g., vector-space cluster analysis) and text-based (e.g., word frequency) ranks are described. Additional techniques to determine a set of concepts, topics or key words associated with each retrieved data objects are described.
