XML documents schema design
The eXtensible Markup Language (XML) is fast emerging as the dominant standard for storing, describing and interchanging data among various systems and databases on the intemet. It offers schema such as Document Type Definition (DTD) or XML Schema Definition (XSD) for defining the syntax and …

Efficient processing of XML documents
In this thesis, we advocate storing XML documents in a relational DBMS, and address the related challenges. In particular, we set out to address the issues of mapping, indexing and updating XML documents.

Safe Template Processing of XML Documents
… Template-Ansatz und setzt diesen für XML-basierte Zielsprachen um. Die dadurch ermöglichte sichere templategestützte Verarbeitung von XML-Dokumenten zeichnet sich durch dadurch aus, das bereits zur Erstellungszeit eines Templates Aussagen über das Ergebnis der Template-Ausprägung …

Efficient Schema Extraction from a Collection of XML Documents
<p>The eXtensible Markup Language (XML) has become the standard format for data exchange on the Internet, providing interoperability between different business applications. Such wide use results in large volumes of heterogeneous XML data, i.e., XML documents conforming to different schemas. …

Tree model guided (TMG) enumeration as the basis for mining frequent patterns from XML documents
… representative of the semi-structured data is XML. Mining frequent patterns from XML poses more challenges in comparison to mining frequent patterns from relational data because XML is a tree-structured data and has an ordered data context. Moreover, XML data in general is larger in data size …

Natural language search of structured documents
… elements in a structured document, such as an XML file. The goal is to create a system capable of being trained to identify features, of written English sentence describing (in natural language) part of an XML document, that help identify the sections of said document which were discussed. In …

Data replication and update propagation in XML P2P data management systems
XML P2P data management systems are P2P systems that use XML as the underlying data format shared between peers in the network. These systems aim to bring the benefits of XML and P2P systems to the distributed data management field. However, P2P systems are known for their lack of central control …

The encapsulation of legacy binaries using and XML-based approach with applications in ocean forecasting
This thesis presents an XML-based approach for the encapsulation of legacy binaries. A method that utilizes XML documents to describe the various parameters and settings for the compilation and execution of an encapsulated binary is discussed. The binary is treated as a black-box component and the …

Pentagonal scheme for dynamic XML prefix labelling
In XML databases, the indexing process is based on a labelling or numbering scheme and generally used to label an XML document to perform an XML query using the path node information. Moreover, a labelling scheme helps to capture the structural relationships during the processing of queries without …

A study of gossip algorithms for internet-scale cardinality estimation of distributed XML data
… of cardinality estimation of XPath queries over XML data stored in a distributed, Internet-scale environment. We focus our work on three objectives: implementing gossip in an Internet-scale environment, conducting a comprehensive performance evaluation in a wide-area network, and analyzing the …

Indexing XML Data for Efficient Twig Pattern Matching
The Extensible Markup Language XML has become the de facto standard for information representation and interchange on the Internet. In this dissertation, I address the problem of indexing and querying XML in two environments, namely, (a) a traditional environment where data is centrally stored and …

A model and an algebra for semi-structured and full-text queries
… formal background. We define a data model for XML documents and propose an algebra able to represent most of XQuery Full-Text expressions. We show how an XQuery Full-Text expression can be translated into an algebraic expression and how an algebraic expression can be optimized.

Improving results for the 2009 and 2010 INEX focused tasks.
… response to a user's query. In past years entire documents which were considered to be relevant or highly correlating were returned to users. However with growth of the web and large numbers of XML documents, smaller elements or passages can be returned to the user for more precise results. This …
