ASlib: A Benchmark Library for Algorithm Selection
The task of algorithm selection involves choosing an algorithm from a set of
algorithms on a per-instance basis in order to exploit the varying performance
of algorithms over a set of instances. The algorithm selection problem is
attracting increasing attention from researchers and practitioners in AI. Years
of fruitful applications in a number of domains have resulted in a large amount
of data, but the community lacks a standard format or repository for this data.
This situation makes it difficult to share and compare different approaches
effectively, as is done in other, more established fields. It also
unnecessarily hinders new researchers who want to work in this area. To address
this problem, we introduce a standardized format for representing algorithm
selection scenarios and a repository that contains a growing number of data
sets from the literature. Our format has been designed to be able to express a
wide variety of different scenarios. Demonstrating the breadth and power of our
platform, we describe a set of example experiments that build and evaluate
algorithm selection models through a common interface. The results display the
potential of algorithm selection to achieve significant performance
improvements across a broad range of problems and algorithms.Comment: Accepted to be published in Artificial Intelligence Journa

The nature of information in the 21st century : conundrums for the informatics community?
Purpose - With the proliferation of electronic information via the web a further distension of the unique characteristics of information has been witnessed. With seismic developments occurring in such a short period of time, it seems prudent to consider the very nature of information and to assess whether this accelerated growth has implications for the work of the informatics community and the information society. Design/methodology/approach - The paper begins by revisiting and refreshing the unique characteristics of information via a reappraisal of the relevant literature. These characteristics are then contextualised within the new economy and traditional economic theory. Once these unique characteristics have been examined, the author discusses how the nature of information in the twenty-first century presents the informatics community with new and difficult challenges. Findings - The challenges posed by the unique nature of information demand a definite response on the part of the informatics community, including the creation of innovative new models to accommodate information's inherent characteristics. Additionally, as the nature of information evolves yet further and ICT innovations accelerate, ever more adaptable skills will be required by the end user in order that value be derived from information. Practical implications - Outcomes and conclusions addressed in the paper may inform the informatics community generally, but will specifically inform the practice of information managers and librarians, and offer ways of assisting them in arriving at holistic decisions with respect to service provision. Originality/value - The paper is a contribution to the debate on the precise nature of information and offers new perspectives on how the informatics community should view information in the twenty-first century
