Information Processing Language
Quick Summary
Information Processing Language (IPL) was an early computer language specifically designed for artificial intelligence (AI) research. Developed by Allen Newell, J. Clifford Shaw, and Herbert Simon, IPL's core feature was its flexible data structure called a "list," which is an ordered sequence of data items that can themselves be lists, allowing for complex structures.12
Building on IPL, John McCarthy created LISP in 1960, which became a primary AI language in the U.S. for decades. Another significant AI language is PROLOG, developed in the 1970s, which uses a theorem-proving technique called resolution to determine logical conclusions from given statements.12
