LINQUISTIC AND WORD-MANIPULATION COMPONENTS IN TEXTUAL INFORMATION SYSTEMS.

In recent years, many myths related to information systems and their implementation to mini- or micro-computers have been shaken. It has been shown, for example, that sophisticated and efficient document retrieval systems, including systems based on the full-text concept, once thought to be implement able only on large mainframe installations, have been indeed developed for mini-computers, and the DOMESTIC system is a good case in point. In this presentation discusses desirability and practicality of adding a linguistic component to such systems. Formal as well as morphological linguistic procedures and files schemes potentially useful for term-processing in such systems are discussed.
