Wednesday September 18, for the second year in a row, I presented at the Big data Expo (#BigDataExpoNL) in Utrecht, the Netherlands on Text-Mining and how it can be used for big-data analytics on unstructured data, in particular for legal fact-finding missions and GDPR/AVG compliance use cases. Large crowds! Very successful event, good to see that big-data is such a hot topic these days!

Problem
"We went to the government to report improper payments and have taken full responsibility for these actions," said
William Weldon, Chairman and CEO of J&J., Last month federal health regulators took legal control of the plant where
millions of bottles of defective medication were produced., The charges against J&J were brought under the Foreign
Corrupt Practices Act, which bars publicly traded companies from bribing officials in other countries to get or retain
business., The company will pay $21.4 million in criminal penalties for improper payments and return $48.6 million in
illegal profits, according to the government., The SEC says J&J agents used fake contracts and sham companies to deliver
the bribes.
Sentiment
giving meaningful credit to companies that self-report, We are committed to holding corporations accountable for bribing
foreign officials, what is honest
Request make sure it complies with anti-bribery laws across its businesses
