The software for doing IR system evaluation.

Previously known as lucy.
Zettair is a (small) set of software written in language C for text indexing and retrieval.
Comment: The index format is very easy to understand. It is easy to add its own weighting scheme too. The straightforward programming style makes easy to add other features (in indexing for instance).
MG is an open-source compressing, indexing and retrieval system for text, images, and textual images. It is written in language C.
Development discontinued since August 1999
Comment: The book does not help too much to understand the software, but anyway it is a very good book on both compression and information retrieval.
The software is more difficult to extend than Zettair because there is heavy use of (complex) macros to tackle with the compression features. But we succeeded in some extensions by inserting our own code in some key points, both in the indexing and the querying phases. However, it is very difficult to create new code to directly access to the index (again this is due to the complex compression mechanisms in use).
Smart implements the basic vector model of information retrieval. It is possible to experiment with different weighting schemes. It is written in language C.
Development discontinued since 1992.
Comment: Not easy to install. The configuration mechanism is difficult to understand. The configuration process is error prone. Some (badly) documented features actually don't work. Extensions that fit well in the vector model are not too difficult but it is quite impossible to add other ones.
Links: Because this software is difficult to use and its internal documentation is not good, here are some links on how to use it.
