Abstract:

The report describes a computer system for the IBM 7094 which produces English indexes of technical Russian text. Part of the indexing system produces a machine dictionary on magnetic tape. This dictionary is a computer representation of standard English-Russian phrase technical dictionaries. A machine dictionary must exist for the same field as the text being indexed. The indexing portion of the system operates upon the machine dictionary. Russian text phrases are matched against Russian dictionary phrases. When a match is found, the English translation is extracted from the dictionary. The final index is constructed from the set of such English translations. The Russian dictionary entries are in canonical form. The indexing system contains reverse inflection algorithms which transform text phrases to their canonical forms.
