We present in this paper a new model for representing probabilistic information in a semi-
structured (XML) database, based on the use of probabilistic event variables. This work is …

As an essential part of the W3C's semantic web stack and linked data initiative, RDF data
management systems (also known as triplestores) have drawn a lot of research attention …

The performance of XML database queries can be greatly enhanced by rewriting them using
materialized views. We study the problem of rewriting a query using materialized views …

XML compression has gained prominence recently because it counters the disadvantage of
the verbose representation XML gives to data. In many applications, such as data exchange …

The resource description framework (RDF for short) provides a flexible method for modeling

Abstract XM LI ndexing and S torage (XMIS) techniques are crucial for the functionality and
the overall performance of an XML database management system (XDBMS). Because of the …

XML is commonly supported by SQL database systems. However, existing mappings of XML
to tables can only deliver satisfactory query performance for limited use cases. In this paper …

A recently introduced double-base number representation has proved to be successful in
improving the performance of several algorithms in cryptography and digital signal …

Dataspaces are recently proposed to manage heterogeneous data, with features like
partially unstructured, high dimension and extremely sparse. The inverted index has been …
