This guide offers an accessible overview of SHRDLU, a landmark AI program from the late 1960s and early 1970s developed by Terry Winograd. It explains how the system processes English conversations about colored blocks by integrating parsing, semantic interpretation, and logical reasoning into a single coherent architecture.
Key points include:
- The historical significance of SHRDLU in AI research at MIT
- A breakdown of its modular subsystems from raw input to natural language response
- How the PROGRAMMAR metalanguage allows grammar rules to act as executable programs
- The function of the Micro-Planner engine for theorem proving within Lisp
- The integration of syntactic, semantic, and geometric world knowledge into a unified system

This Perspective outlines ways in which generative artificial intelligence aligns with and supports the core ideas of generative linguistics, and how generative linguistics can provide criteria to evaluate and improve neural language models.
Dr Valeria Correa Vaz de Paiva is a Brazilian mathematician, logician, computer scientist, and computational linguist known for introducing the concept of dialectica spaces, which model linear logic in advanced programming languages. She has contributed significantly to natural language processing (NLP) and works at the Topos Institute in Berkeley, California. De Paiva is committed to encouraging more women into STEM fields and is actively involved in Women In Logic (WIL).
