The link to Snorkel [1] is really interesting, labeling data in a low quality programmatic way, which is then fed through a neural network to produce high quality labels is really smart.
Yes, Snorkel and DeepDive look extremely useful. At my job we have a lot of data but it's unlabeled, it will cost millions of dollars to outsource it to India for labeling/data entry.
