Entity matching (a.k.a. record linkage) plays a crucial role in integrating multiple data sources, and numerous matching solutions have been developed. However, the solutions have largely exploited only information available ...

SQL extensions that allow queries to explicitly specify data quality requirements in terms of currency and consistency were proposed in an earlier paper. This paper develops a data quality-aware, finer grained cache model ...

K-Anonymity has been proposed as a mechanism for privacy protection in microdata publishing, and numerous recoding ?models? have been considered for achieving kanonymity. This paper proposes a new multidimensional model, ...

We consider the problem of how to combine structure indexes and inverted lists to answer queries over a native XML DBMS, where the queries specify both path and keyword constraints. We augment the inverted list entries to ...

Privacy is an important issue in data publishing. Many organizations distribute non-aggregate personal data for research, and they must take steps to ensure that an adversary cannot predict sensitive information pertaining ...

We identify a broad class of aggregate queries, called MPF queries, inspired by the literature on marginalizing product functions. MPF queries operate on �functional relations,� where a measure attribute is functionally ...

Several recent works have focused on OLAP over imprecise data, where each fact can be a region, instead of a point, in a multi-dimensional space. They have provided a multiple-world semantics for such data, and ...

Increasingly, Web data is displayed in pages generated according to a template (e.g., product listings at amazon.com, faculty directories, class schedules). This trend makes structured querying of such Web data a valuable ...
