ObjectRank: a system for authority-based search on databases

Abstract

We present ObjectRank demo system that performs authority-based keyword search on bibliographic databases. We also provide Inverse ObjectRank as a keyword-specific specificity metric and other calibration parameters such as Global ObjectRank. Users can specify various combinations of calibration values to control the behavior of the demo. Finally, we propose a methodology that enables us to extend query results using the ontology graph.
