Recent efforts made by the MIR community is pushing for the creation of a standardised framework for MIR system evaluation. Such a framework will allow the community to collaborate on important issues and ultimately progress this dynamic area of research further. Some of these efforts are asking if a framework similar to TREC is the way forward. In this… (More)
As part of the celebration of twenty-five years of ACM SIGIR conferences we performed a content analysis of all papers published in the proceedings of SIGIR conferences, including those from 2002. From this we determined, using information retrieval approaches of course, which topics had come and gone over the last two and a half decades, and which topics… (More)
As the end of Moores-law is on the horizon, power becomes a limiting factor to continuous increases in performance gains for single-core processors. Processor engineers have shifted to the multicore paradigm and many-core processors are a reality. Within the context of these multi-core chips, three key metrics point themselves out as being of major… (More)
Geneticists today spend as much time cataloguing and analysing digital data as they do in wet labs. One of the key problems they face, is that of identifying genes and publications that are relevant to their work or research. This paper describes an approach to retrieval that incorporates structural MeSH heading data into the search process. In particular,… (More)
Advancing research will enable an interconnection network to support the same seamless virtualization found in other parts of hardware, such as CPUs. Such a network thus poses particular challenges as well as opportunities for a utility computing data center.
Overlapping Reconfiguration is currently the most efficient method to reconfigure an interconnection network, but is only valid for systems that apply distributed routing. This paper proposes a solution which enables utilization of Overlapping Reconfiguration in a source routed environment. We demonstrate how a synchronized injection of tokens has a… (More)
Maintaining high system utilisation is a key factor for data centres. However, strictly partitioning the datacentre resources to fully isolate the concurrent applications (contention freedom) leads to poor system utilisation because of fragmentation. We present an allocation algorithm for fat-trees (which are commonly found in large-scale data centres)… (More)
