Keyword-based web query languages suffer from a lack of precision when searching for a precise kind of documents. Indeed, some documents cannot be simply characterized by a list of keywords. For example, searching for on-line pictures dealing with formula one using only simple keywords with general-purpose search-engines gives imprecise answers. This imprecision is due to the method that consid...

During an adaptive k-out-of-N oblivious transfer (OT), a sender has N private documents, and a receiver wants to adaptively fetch k documents from them such that the sender learns nothing about the receiver’s selection and the receiver learns nothing more than those chosen documents. Many fully simulatable and universally composable adaptive OT schemes have been proposed, but those schemes typi...

In text analytics (Srivastava & Sahami 2009), document clustering refers to the problem of automatically grouping documents into different groups (known as clusters), such that documents in one cluster are similar to each other while being dissimilar from the ones in a different cluster. Typically, the dataset is represented using the vector model in which a set of m documents with n unique wor...

We present a novel streaming algorithm for evaluating XPath expressions that use backward axes (parent and ancestor) and forward axes in a single document-order traversal of an XML document. Other streaming XPath processors, such as YFilter, XTrie, and TurboXPath handle only forward axes. We show through experiments that our algorithm significantly outperforms (by more than a factor of two) a t...

TNTBASE is an open-source versioned XML database obtained by integrating Berkeley DB XML into the Subversion Server. The system is intended as a basis for collaborative editing and sharing XML-based documents. It integrates versioning and fragment access needed for finegranular document content management. Nowadays well-formedness of electronic documents plays a giant role in the contemporary d...

This whitepaper offers a brief introduction to the BIN system of the Social, Political and Economic Event Database (SPEED) project. BIN provides automatic document categorization of highly nuanced topics across massive-scale document archives. The BIN system allows a group of trained human editors to present the computer with a relatively small collection of hand-categorized documents represent...

Validation of XML documents is often treated as a major operation, performed only at major transitions in the document's life cycle, after it has been created or when it enters some new stage of processing. Users editing XML documents, on the other hand, would appreciate instantaneous feedback of the correctness of the document each time anything changes. Such on-the-fly validation can be imple...
