Secure XML querying with security views
TLDR
The prevalent use of XML highlights the need for a generic, flexible access-control mechanism for XML documents that supports efficient and secure query access, without revealing sensitive information unauthorized users. Expand

Approximate query processing using wavelets
TLDR
In this paper, we propose the use of multi-dimensional wavelets as an effective tool for general-purpose approximate query processing in modern, high-dimensional applications. Expand

Sketching probabilistic data streams
TLDR
In this paper, we propose the first space- and time-efficient algorithms for approximating complex aggregate queries (including, the number of distinct values and join/self-join sizes) over probabilistic data streams. Expand

Sketching Streams Through the Net: Distributed Approximate Query Tracking
TLDR
In this paper, we propose novel algorithmic solutions for the problem of continuously tracking a broad class of complex aggregate queries in such a distributed-streams setting. Expand

Efficient filtering of XML documents with XPath expressions
TLDR
We propose a novel index structure, termed XTrie, that supports the efficient filtering of XML documents based on XPath expressions that supports both ordered and unordered matching of XML data. Expand

XTRACT: a system for extracting document type descriptors from XML documents
TLDR
We propose XTRACT, a novel system for inferring a DTD schema for a database of XML documents that incorporates the full expressive power of regular expressions to generate concise and semantically meaningful DTD schemas. Expand
