The following systems are available for use in this course. Those
with links can be downloaded freely and used anywhere. For access to
other systems, please check with the teaching assistant. The three
you are most likely to want to use are listed first, others are listed
in alphabetical order for completeness.
- An integrated Java package that includes components from
Lucene, Terrier, and the Stanford NLP tools.
- A freely available Java IR system, probably the easiest system
to get up and running, and the most easily modified.
- Indri is optimized for efficiency, and thus is probably the
best choice if you have a very large collection. It is built
on top of the Lemur toolkit for
building language modeling systems for information retrieval.
- Zettair is optimized for both efficiency and modifiability. It
therefore occupies a part of the design space between Lucene and
- Cheshire 3
- Freely available research software implementing a logistic
regression model from the University of California at Berkeley.
Gettig it working may require some facility with Z39.50.
- Freely available software from the University of Arizona that
is designed for efficient indexing (at some cost in retrieval
efficiency). Glimpse is not configured for TREC-style
evaluations, so that would take some extra work.
- Commercial software based on inference networks that has a very
flexible query language. We have a research and teaching
license for this system from the University of Massachusetts,
and still use it occassionally. InQuery includes a fairly nice
X-Windows interface and it is configured to run TREC-style
evaluations, but the source code is not available.
- A Java toolkit for building IR systems for small applications.
The strength of IRF is that the object oriented framework greatly
simplifies tasks that require working wiht the source code. Bt
because Java is designed for platform independence rather than
efficiency, the size of the collections that can be handled is quite
- Research software from the Royal Melbourne Institute of
Technology that is designed to maximize storage efficiency on
very large collectons. It is available under the GNU public
license. We installed this once several years ago and it
wasn't too difficult.

- Public domain vector space research software developed at NIST
We regularly use this system for TDT evaluations. PRISE
includes a very nice Z39.50 interface, but it takes some
facility with that stangard to get the interactive part
running. PRISE is configured to run TREC-style evaluations and
the source code is available.
- A vector space research software that is freely available by FTP
from Cornell University. We have extensive experience using
SMART. SMART includes only a VT-100 interface, but it is
configured to run TREC-style evaluations and the source code is
- An information retrieval system from the University of Glasgow
that is optimized for efficiency. Terrier implements the
divergence from randomness framework for ranked retrieval.
- An open source IR system that is designed ot run under Linux.
Xiapan is a descendent of Omseek, which itself is a decendent
of Open Muscat. Xiapan is designed to handle several Western
European languages, and thus might be a good choice if you want to
work with languages other than English.
