The purpose of this document is to introduce a collection of programs to be found in the Vector Space ISR Workbench.
The workbench presently consists of about fifty modular programs written in Mumps and/or bash script. These programs implement the basic Vector Space Model for document classification and retrieval as originally developed by G. Salton [Salton, 1968, 1983, 1988, 1992] and others. Also included is a collection of approximately 294,000 medical abstracts for testing and experiments.
The purpose of this package is to facilitate teaching, exploration and experimentation with the vector space model and the development of new algorithms and techniques. The modular design of the code together with the Mumps multidimensional database model enable the user to experiment, augment, and measure various indexing strategies.
Currently, the package contains programs that perform:
Most of the code in these modules is written in Mumps, a language developed in medicine in the late 1960s [Barnett 1970, Bowie 1976, O'Kane 2008] which supports a string handling and a multidimensional database model which is ideally suited for vector space model implementations. The Mumps modules are invoked by bash scripts which control flow of data and multitasking.
