According to Douglas Lenat, Cyc can perform "semantic search". Google cannot reply to questions such as "What is the weather in the capital of France?", although it has access to web sites with information on the weather in Paris. It's search engine is syntactic (it looks for words). A search engine using Cyc, however, could answer this question correctly, because it would have the information that Paris is the capital of France as part of its database of commonsense knowledge. Douglas Lenat also shows how it could find a picture of a "man smiling" by identifying a caption that describes a man playing with his daughter. Cyc can consult its database and determine that parents spending time with their children will often be happy, and happy people often smile.
