We study the problem of efficiently estimating counts for queries involving complex filters, such as user-defined functions, or predicates involving self-joins and correlated subqueries. For such queries, traditional sampling techniques may not be ap

We present a system, Perada , for parallel perturbation analysis of database queries. Perturbation analysis considers the results of a query evaluated with (a typically large number of) different parameter settings, to help discover leads and evaluat

Iceberg queries, commonly used for decision support, find groups whose aggregate values are above or below a threshold. In practice, iceberg queries are often posed over complex joins that are expensive to evaluate. This paper proposes a framework fo

Forward looking ground penetrating radar (FLGPR) is an alternative buried threat sensing technology designed to offer additional standoff compared to downward looking GPR systems. Due to additional flexibility in antenna configurations, FLGPR systems

Are you fed up with "lies, d---ned lies, and statistics" made up from data in our media? For claims based on structured data, we present a system to automatically assess the quality of claims (beyond their correctness) and counter misleading claims t

Exploring the evolution of social contexts with time can provide unique insights into human social dynamics. Several social contexts and relationships can be mined from unstructured text articles that describe social phenomena. In contrast to structu
