No, they often do not extract them from the pdf. They often search in the pdf
for a doi and then provide the actual data from a provider such as ISI WOS or
other data base sources. BibDesk does not do that. As a consequence you see in
BibDesk how lousy the meta data in the pdf generally actually are (at least in
my experience).

All the data continuously generated in your IT infrastructure contains a
definitive record of customers, application performance, security
threats, fraudulent activity and more. Splunk takes this data and makes
sense of it. Business sense. IT sense. Common sense.
