The document discusses building an open knowledge base called WikiFactMine that is controlled by researchers rather than large corporations. It notes that scholarly publishing produces a large amount of "Big Data" each year, most of which is not publicly readable or fully utilized. Content mining can help liberate this knowledge by extracting facts from millions of articles each week. However, large publishers often oppose content mining. The document advocates for supporting content mining and researchers to address issues like climate change and improve science. It notes that content mining software can extract information much faster than manual review.
