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 the need to access the physical document.
Two of the main problems for labelling XML schemes are duplicated
labels and the cost efficiency of labelling time and size. This research
presents a novel dynamic XML labelling scheme, called the Pentagonal
labelling scheme, in which data are represented as ordered XML nodes
with relationships between them. The update of these nodes from large scale XML documents has been widely investigated and represents a
challenging research problem as it means relabelling a whole tree. Our
algorithms provide an efficient dynamic XML labelling scheme that
supports data updates without duplicating labels or relabelling old nodes.
Our work evaluates the labelling process in terms of size and time, and
evaluates the labelling scheme’s ability to handle several insertions in
XML documents. The findings indicate that the Pentagonal scheme
shows a better initial labelling time performance than the compared
schemes, particularly when using large XML datasets. Moreover, it
efficiently supports random skewed updates, has fast calculations and
uncomplicated implementations so efficiently handles updates. Also, it
proved its capability in terms of the query performance and in determining
the relationships.Libyan governmen
Textual Assemblages and Transmission: Unified models for (Digital) Scholarly Editions and Text Digitisation
Scholarly editing and textual digitisation are typically seen as two distinct, though related,
fields. Scholarly editing is replete with traditions and codified practices, while the digitisation
of text-bearing material is a recent enterprise, governed more by practice than theory. From
the perspective of scholarly editing, the mere digitisation of text is a world away from the
intellectual engagement and rigour on which textual scholarship is founded. Recent
developments have led to a more open-minded perspective. As scholarly editing has made
increasing use of the digital medium, and textual digitisation begins to make use of scholarly
editing tools and techniques, the more obvious distinctions dissolve. Such criteria as ‘critical
engagement’ become insufficient grounds on which to base a clear distinction. However, this
perspective is not without its risks either. It perpetuates the idea that a (digital) scholarly
edition and a digitised text are interchangeable.
This thesis argues that a real distinction can be drawn. It starts by considering scholarly
editing and textual digitisation as textual transmissions. Starting from the ontological
perspective of Deleuze and Guattari, it builds a framework capable for considering the
processes behind scholarly editing and digitisation. In doing so, it uncovers a number of
critical distinction. Scholarly editing creates a regime of representation that is self-consistent
and self-validating. Textual digitisation does not. In the final chapters, this thesis uses the
crowd-sourced Letters of 1916 project as a test-case for a new conceptualisation of a scholarly
edition: one that is neither globally self-consistent nor self-validating, but which provides a
conceptual model in which these absences might be mitigated against and the function of a
scholarly edition fulfilled

Visually Exploring and Querying XML with BaseX
XML documents are widely used as a generic container for textual contents. As they are increasingly growing in size, XML databases are emerging to efficiently store and query their contents. Besides, due to the hierarchic structure of XML documents, hierarchic visualizations are needed to facilitiate cognitive access to query results. BaseX is a simple database prototype, mapping XML documents to a table based tree encoding. An integrated treemap visualization and a query interface allow visual access to the documents and demonstrate the efficiency of the underlying data storage
