This work describes novel methods and techniques to decrease the cost of employing active learning in text categorisation problems. The cost of performing active learning is a combination of labelling effort and computational ...

The recent development of large FPGAs combined with the availability of a variety of FPGA-based non-integer arithmetic cores has made it possible to implement high performance matrix kernel operations on FPGAs. This thesis ...

Traditionally much research on computer supported collaborative learning, CSCL, focused on either learning through distant collaboration or face-to-face collaboration sharing a computer. A new and emergent area within CSCL ...

Traditional search operations, topic detection or summarisation of meeting recordings are generally performed using segmentation and indexing techniques originally developed in the field of Multimedia Information Retrieval. ...

Ontology-based approaches that formally represent the meaning of information in a system, offer the hope of dealing with semantic heterogeneity when integrating heterogeneous data sources [Halevy 2001, Noy 2004, Wache et ...

The measurement of quality in colonoscopy is an active topic in medical research. Studies report significant miss rates in the detection of colorectal lesions. This has raised the concern among gastroenterologists that the ...

Service networks and the assignment of tasks on such networks are prevalent abstractions in a spectrum of domains spanning manufacturing systems, where a strict dependency on the execution of the tasks exist, load-balancing ...

Biobanks or bio-repositories facilitate the storage and maintenance of biological samples and data to support discovery of biomarkers, therapeutic targets, and the underlying causes of diseases. Such discoveries require ...
