There has been an increased demand for characterizing user access patterns using web mining techniques since the informative knowledge extracted from web server log files can not ...
The challenges of wireless and mobile computing environments have attracted the attention of researchers to revisit the conventional implementation of distributed computing paradi...
We propose a path-based scheme for storage and retrieval of RDF data using a relational database. The Semantic Web is much anticipated as the nextgeneration web where high-level p...
In order to facilitate query processing for XML data, several path indexing, labelling and numbering scheme have been proposed. However, if XML data need to be updated frequently,...
In this paper, a new mapping model, called n-INode, is presented and it is used to support dynamic updating of XML data flexibly. One key feature of n-INode is the use of multi-di...
XML query caching for XML database-backed Web applications began to be investigated recently. However, the issue of how the cached query results are stored has not been addressed ...
The transformation and manipulation of XML is an increasingly important research topic. This paper examines a number of issues with regard to languages for transforming and reacti...
A Self-Adaptive Recovery Net (SARN) is an extended Petri net model for specifying exceptional behavior in workflow systems. SARN caters for high-level recovery policies that are ...
