Craig Macdonald from University of Glasgow and ECIR, sent me this upgrade and Call for Participation concerning the Terrier platform.

BTW, if you are taking the Search Engines Architecture grad course, after thinking thoroughly I believe is better to go with Terrier (JAVA) as the base architecture for the course main project. I don’t think we have enough time to build and deal with a C++/PHP/Perl Frankenstein, with all associated incompatibility issues, nor is necessary to reinvent the wheel for the next 9 weeks. I wish we all have more time in this life.

So, students, please start downloading Terrier now. We don’t have classes this Saturday, so we have plenty of time to read and catch up with the release. Next time we meet I will explain how to use their Desktop Search component. We will build/tweak as much as we can of the architecture.

The great thing about Terrier is that other researchers at the ECE&CS department can then use it for other experiments on data mining.

Here is Macdonald’s announcement:

Terrier, IR Platform v 2.1 – 19/03/2008

http://ir.dcs.gla.ac.uk/terrier/

Terrier 2.1, the next version of the open source IR platform from the
University of Glasgow (Scotland) has been released.

This is a minor update, which contains some bug fixes, and some minor
improvements. Support for indexing various test collection has been
improved (CLEF, TREC Legal track), and the flexibility of the settings
of some applications such as the Desktop search and the Interactive
Terrier have been enhanced.. Moreover, Terrier 2.1 includes a file
system abstraction layer, which allows various types of files to be
accessed through a uniform API. For example, indexing an HTTP Web page
is as straightforward as indexing a local document. Moreover, a notable
indexing bug affecting only the Windows platform was resolved.

Final Call for Participation:

ECIR 2008 Tutorial: Research and building IR applications using Terrier
30th March

This tutorial introduces the main design of a large-scale IR system, and
uses the Terrier platform as an example of how one should be built. We
detail the architecture and data structures of Terrier, as well as the
weighting models included, and describe, with examples, how Terrier can
be used to perform experiments and extended to facilitate new research
and applications.

Handouts containing slides, a Terrier “crib sheet”, and detailed
examples of implementations of common research problems will be
provided, in addition to a bibliography of informative related papers.

Presenters: Craig Macdonald and Ben He, University of Glasgow, UK
