This paper describes some of the features of the new 32-bit Windows version of PAHO’s English-Spanish (ENGSPAN®) and Spanish-English (SPANAM®) machine translation software. The new dictionary update interface is designed to help users add their own terminology to the lexicon and encourage them to write context-sensitive rules to improve the quality of the output. Expanded search capabilities provide instant access to related source and target entries, expressions, and rules. A live system demonstration will accompany this presentation.
