Over the past few years, HNC has developed a neural network based, vector space approach to text retrieval. This approach, embodied in a system called MatchPlus, allows the user to retrieve information on the basis of meaning and context of a fi'ee text query. The MatchPlus system uses a neural network based, constrained sel~organization technique to learn word stem interrelationships directly 3~om a training corpus, thereby eliminating the need for hand crafted linguistic knowledge bases and

These enhancements include the development of a one step learning law that greatly reduces the amount of time and~or computational resources required to train the system, and the development of a prototype multilingual (English and Spanish) text retrieval system.
