Abstract
ELI, the English language interpreter for the SAM story understanding system at Yale, is a model of language understanding using productions. Productions are useful because they are flexible, but this flexibility means more work has to be spent controlling and manipulating them. ELI limits the number of productions that have to be manipulated with expectations. Expectations are constraints generated by frame structures that have been built by previously executed productions. Only productions that satisfy existing expectations are used.

Steps Toward Knowledge-Based Machine Translation

TL;DR: This paper considers the possibilities for knowledge-based automatic text translation in the light of recent advances in artificial intelligence, and argues that competent translation requires some reasonable depth of understanding of the source text and access to detailed contextual information.
