A pivotal moment came with the release of the ALPAC report in 1966. Commissioned by the U.S. government, this analysis offered a sobering view of the progress of machine translation. The bleak critique underlined the inefficacy of existing models and systems, even going so far as to question the plausibility of significant advancements in the foreseeable future. As a result, federal funding for machine translation research witnessed a sharp decline.

Yet, it’s crucial to note that this decade wasn’t defined merely by stagnation or disillusionment. While large-scale translation initiatives waned, the era was also marked by the genesis of rule-based systems. These systems, rooted in handcrafted rules and heuristics, marked a significant shift. Instead of merely translating, the objective was to ensure machines could comprehend and generate human language within specific, narrow domains.

Moreover, the 1970s saw the emergence of computational linguistics as a distinct academic discipline. Universities began fostering environments that interwove linguistics, cognitive science, and computer science, leading to rich interdisciplinary dialogues.
