 However by the late 1970s, as computers became faster and less expensive, some in the burgeoning AI community started to claim that their programs could understand English sentences, using a database of background information. The work of one of these, Yale researcher Roger Schank (Schank &amp; Abelson 1977) came to Searle’s attention.Schank developed a technique called “conceptual representation” that used “scripts” to represent conceptual relations (related to Conceptual Role Semantics). Searle’s argument was originally presented as a response to the claim that AI programs such as Schank’s literally understand the sentences that they respond to.
