Without disclosing things I shouldn't disclose (professionally if not legally), a lot of the acqusition was acquihire and then went on to cognitive services. A lot of what the powersetters did was bring their expertise in indexing in. The Powerset indexing requirements were fairly intense, so bing getting those was a big leg up over the previous (good, but somewhat less informed) work. A lot of the stuff we had at Powerset as custom services is now in Google and MS cognitive services. It's so cool to have access to those tools again. Luis.ai is really really fun to use lately.
