XML Topic Map Builder: Specification and Generation

Everyday thousands of new information resources are linked to the web. This way the web is growing very fast what makes search tasks more difficult. To solve the problem several initiatives were undertaken and a new area of research and development emerged: the one called Semantic Web. When we refer to the semantic web we are thinking about a network of concepts. Each concept has a group of rel...

XML Query Optimization in Map-Reduce

We present a novel query language for large-scale analysis of XML data on a map-reduce environment, called MRQL, that is expressive enough to capture most common data analysis tasks and at the same time is amenable to optimization. Our evaluation plans are constructed using a small number of higher-order physical operators that are directly implementable on existing map-reduce systems, such as ...

XML-BSPM: an XML format for storing Body Surface Potential Map recordings

BACKGROUND The Body Surface Potential Map (BSPM) is an electrocardiographic method, for recording and displaying the electrical activity of the heart, from a spatial perspective. The BSPM has been deemed more accurate for assessing certain cardiac pathologies when compared to the 12-lead ECG. Nevertheless, the 12-lead ECG remains the most popular ECG acquisition method for non-invasively assess...

Using Map and Reduce for Querying Distributed XML Data

Semi-structured information is often represented in the XML format. Although, a vast amount of appropriate databases exist that are responsible for efficiently storing semistructured data, the vastly growing data demands larger sized databases. Even when the secondary storage is able to store the large amount of data, the execution time of complex queries increases significantly, if no suitable...
