By reducing the number of characters to be coded the problem of devising a numerical code for the Cyrillic alphabet can be simplified. This reduction can be achieved by providing code-words for only the lower-case forms of characters that do not occur initially; by disregarding the diacritic of the character ё, and by disregarding the character ё entirely. Ambiguities that arise in the latter cases can be resolved by an examination of the context. | Mechanical Translation December 1957 pp. 76-78 A Refinement in Coding the Russian Cyrillic Alphabet B. Zacharov London University London England By reducing the number of characters to be coded the problem of devising a numerical code for the Cyrillic alphabet can be simplified. This reduction can be achieved by providing code-words for only the lower-case forms of characters that do not occur initially by disregarding the diacritic of the character e and by disregarding the character e entirely. Ambiguities that arise in the latter cases can be resolved by an examination of the context. THE PROBLEM of coding the Russian Cyrillic alphabet in numerical form has been considered previously in several papers 1 and it is clear that it would be desirable if each character of the Russian alphabet together with any required numbers punctuation marks and capitals could be coded in such a way that a separate unique numerical code-word existed for each lower-case character capital etc. Unfortunately the speed of modern digital computers and the size of their memories are such that a code of this form would result in considerable time being spent in the memory search for the appropriate target language equivalent. It is clear then that ways must be found apart from engineering advances to speed up the memory search time. One way of doing this would be to decrease the amount of linguistic data stored in the memory and this has been considered. 2 Another method would be to decrease the amount of numerical data . the number of bits in the memory for a given number of source language characters.
