The MG software system has been used for several years as a testbed for research into the implementation of large-scale infomation retrieval systems. Initially designed as a platform for experiments with document compression techniques, index compression mechanisms, and index construction algorithms, MG has also been used as a tool in the study of query evaluation strategies and similarity heuristics. The MG system has also been used since the inception of TREC as the basis of much of the information retrieval experimentation done in Melbourne at RMIT and the University of Melbourne, as well as several other research centres. In this demonstration we will display the latest version of MG, called Teraphim, which supports distributed information retrieval across local and wide area networks.
