Microsoft open sources code to give any app Bing-like intelligence

To search the vectors, Microsoft uses an algorithm it calls SPTAG (“Space Partition Tree and Graph”). Microsoft has released today the SPTAG algorithm as MIT-licensed open source on GitHub. The release of SPTAG is an example of how Microsoft is putting those words into practice; the combination of an Azure service and open source means that developers can start with the more constrained, easy-to-use service, and as their expertise or requirements grow more complex, they can use SPTAG to build their own services.
