Twig queries have been extensively studied as a major fragment of XPATH queries to query XML data. In this paper, we study PXMLRANK query, (Q, k), which is to rank top-k probabili...
Unlike their hard realtime counterparts, soft realtime applications are only expected to guarantee their ”expected delay” over input data space. This paradigm shift calls for ...
We propose a new method for automated large scale gathering of Web images relevant to specified concepts. Our main goal is to build a knowledge base associated with as many conce...
