l The early history of MT: 1950s • Machine translation research began in the early 1950s on machines less powerful than high school calculators • Foundational work on automata, formal languages, probabilities, and information theory • MT heavily funded by military, but basically just simple rule-based systems doing word substitution • Human language is more complicated than that, and varies more across languages! • Little understanding of natural language syntax, semantics, pragmatics • Problem soon appeared intractable Pre-Neural Machine Translation
