The Thesaurus in Syntax and Semantics
The recent work of the Unit has been primarily concerned with the employment ofthesauri in machine translation. Limited success has been achieved, in punchedcardtests, in improving the idiomatic quality and so the intelligibility of an initiallyunsatisfactory translation, by word-for-word procedures, from Italian intoEnglish, by using a program which permitted selection of final equivalents from"heads" in Roget's Thesaurus, i.e. lists of synonyms, near-synonyms and associatedwords and phrases, instead of from previously determined lists of alternativetranslations.

Dynamic Programming
The Dawn of Dynamic Programming Richard E. Bellman (1920–1984) is best known for the invention of dynamic programming in the 1950s. During his amazingly prolific career, based primarily at The University of Southern California, he published 39 books (several of which were reprinted by Dover, including Dynamic Programming, 42809-5, 2003) and 619 papers. Despite battling the crippling effects of a brain injury, he still published 100 papers during the last eleven years of his life. He was a frequent informal advisor to Dover during the 1960s and 1970s. Professor Bellman was awarded the IEEE Medal of Honor in 1979 "for contributions to decision processes and control system theory, particularly the creation and application of dynamic programming."
Appendix on Can machines think?
Between 1946 and 1956, a number of BBC radio broadcasts were made by pioneers in the fields of computing, artificial intelligence and cybernetics. Although no sound recordings of the broadcasts survive, transcripts are held at the BBC's Written Archives Centre at Caversham in the UK. This paper is based on a study of these transcripts, which have received little attention from historians. The paper surveys the range of computer-related broadcasts during 1946-1956 and discusses some recurring themes from the broadcasts, especially the relationship of'artificial intelligence' to human intelligence.
