Symbolic AI

In the 1980s people were as excited about AI as they are today but the technology was completely different.

Researchers sought to put knowledge into machines one fact at a time.

One approach, expert systems, was based on programming rules. Another approach, semantic networks, attempted to break down language (essentially just words) into a computable form.

Both approaches were called “knowledge representation” or, more commonly today, symbolic AI and even Good Old-Fashioned AI.

The AI Winter 1990 – 2000

Symbolic AI was so over-hyped and so under-delivered that people became disillusioned about the whole notion of AI for awhile.
