Powerset was a true revolution in the world of search. The San Francisco based company heavily invested in Semantic technologies and has pioneered the way users could search and consume Web content with the help of semantic and linguistic technologies. Powerset, among other sources, has also indexed Freebase’s open database of structured information before it got acquired by Google to become Google’s knowledge graph.
The SERP of Powerset included Factz – an innovative design element with a summary of key information extracted from Wikipedia pages. The company started in 2005 was acquired by Microsoft in 2008 and became a strategic asset in the evolution of Bing.
Powerset’s Wikipedia search engine didn’t slow down Google, but it did raise significantly the bar on the search experience for all major search engines.
