The software systems reviewed are: AIDA, CLARIT, Metamorph, SIMPR, STATUS/IQ, TCS, TINA and TOPIC. The hardware systems reviewed are: CAFS‐ISP, the Connection Machine, GESCAN,HSTS,MPP, TEXTRACT, TRW‐FDF and URSA.

Abstract

In the third paragraph, the author states that ‘Conventional text retrieval systems suffer from a number of problems. First, indexing terms and / or classificators have normally to be assigned manually, which is a very time‐consuming process and can lead to severe problems with regard to inter‐indexer consistency.’ To what types of systems does this refer?
