Efficient processing of top-k queries is a crucial requirement in many interactive
environments that involve massive amounts of data. In particular, efficient top-k processing …

Uncertainty accompanies our life processes and covers almost all fields of scientific studies.
Two general categories of uncertainty, namely, aleatory uncertainty and epistemic …

摘要随着数据采集和处理技术的进步, 人们对数据的不确定性的认识也逐步深入. 在诸如经济,

In recent years, a number of indirect data collection methodologies have lead to the
proliferation of uncertain data. Such data points are often represented in the form of a …

Finding top-k elephant flows is a critical task in network traffic measurement, with many
applications in congestion control, anomaly detection and traffic engineering. As the line …

Probabilistic frequent itemset mining in uncertain transaction databases semantically and
computationally differs from traditional techniques applied to standard" certain" transaction …

Modern enterprise applications are forced to deal with unreliable, inconsistent and
imprecise information. Probabilistic databases can model such data naturally, but SQL query …

Uncertain data is inherent in a few important applications such as environmental
surveillance and mobile object tracking. Top-k queries (also known as ranking queries) are …

Complex networks, such as biological, social, and communication networks, often entail
uncertainty, and thus, can be modeled as probabilistic graphs. Similar to the problem of …

Reverse skyline queries over uncertain databases have many important applications such
as sensor data monitoring and business planning. Due to the existence of uncertainty in …
