Microsoft open-sources a part of Bing’s ranking algorithm

Microsoft announced in their official blog that they are releasing AI tools that are used in Bing’s ranking algorithm to the general public.

“Microsoft has made one of the most advanced AI tools it uses to better meet people’s evolving search needs available to anyone as an open source project on GitHub. […]

The algorithm, called Space Partition Tree And Graph (SPTAG), allows users to take advantage of the intelligence from deep learning models to search through billions of pieces of information, called vectors, in milliseconds. That, in turn, means they can more quickly deliver more relevant results to users.

Microsoft uses vector search for its own Bing search engine, and the technology is helping Bing better understand the intent behind billions of web searches and find the most relevant result among billions of web pages.”
