There's more data to protect than just your Facebook profile. Facebook News Feeds will alert users if their data was improperly obtained by Cambridge Analytica. With Facebook CEO Mark Zuckerberg set to testify before Congress on the scandal involving data firm Cambridge Analytica, the social network is informing individual users their profiles may have been used for the firm's political targeting without their consent. Starting at noon ET Monday, Facebook was scheduled to begin alerting users if they were some of the estimated 87 million whose profiles Facebook says were scraped and improperly shared with Cambridge Analytica. What users will do with that information boils down to engaging in the boring but eye-opening privacy clean-ups many have already embarked on, finding all the apps that had access to your info and then cutting this access off. Bad news: with the data leak over three years old, it's too late to take what's already out there back.

Facebook founder Mark Zuckerberg has been receiving special coaching on how to present himself when he appears before US politicians demanding to know what he is doing to protect users' data, and how Russia was able to use his platform to allegedly meddle in the 2016 presidential election. Amid continuing controversy over the inappropriate harvesting of the data of up to 87 million Facebook users by British political consulting firm Cambridge Analytica, Mr Zuckerberg will try and reassure Congress he is taking the concerns of them and the general public seriously. He will also try to deflect the efforts of those who favour more stringent government regulation. "It's clear now that we didn't do enough to prevent these tools from being used for harm," he is expected to tell the House Committee on Energy and Commerce, according to written testimony released ahead of his appearance. "We didn't take a broad enough view of our responsibility, and that was a big mistake. It was my mistake, and I'm sorry. I started Facebook, I run it, and I'm responsible for what happens here."

Facebook is contacting users whose data it says may have been shared with Cambridge Analytica, with around 87 million people expected to receive a message in their newsfeed from Monday. The platform says the majority of users who could be affected – around 70 million – are in the US, but some will be in the UK. We would like to hear from people who see the message, and to find out more about how you think Facebook has handled the situation. Are you one of the 87 million users Facebook says it is contacting? Are you aware of any connections or settings that may have made your data vulnerable?

Future Tense is a partnership of Slate, New America, and Arizona State University that examines emerging technologies, public policy, and society. Facebook suspended two companies from its platform over the weekend for improper data collection. The social media giant has been racing to address privacy concerns in light of revelations that data firm Cambridge Analytica accessed private data from as many as 87 million accounts and later used it to support Donald Trump's presidential campaign. Late on Friday, Facebook responded to reports that the Canadian political consulting firm AggregateIQ is affiliated with Strategic Communication Laboratories (SCL), the parent company of Cambridge Analytica. "In light of recent reports that AggregateIQ may be affiliated with SCL and may, as a result, have improperly received FB user data, we have added them to the list of entities we have suspended from our platform while we investigate," Facebook said in a statement.

In 2014, a researcher named Alexander Kogan created a personality quiz that 270,000 Facebook users would go onto install. From those downloads alone, he was able to harvest the personal information of up to 87 million people, according to Facebook's most recent estimate. He then passed that data along to Trump-affiliated political firm Cambridge Analytica, which would use it to target voters in the 2016 presidential election. Now Facebook has finally released a tool that lets you know if you were affected. Beginning at noon ET on Monday, some Facebook users will see one of two messages at the top of their News Feed.

Facebook has said it believes that up to 87 million users' data was improperly shared with Cambridge Analytica.

The Facebook crisis involving Cambridge Analytica's data breach leads many to question how Facebook treats their users' data; Reaction on'Outnumbered.' The man who revealed the Cambridge Analytica data-harvesting scandal said Sunday he believed the political consulting firm snatched information from more than the previously reported 87 million Facebook users. "I think that there is, you know, a genuine -- a genuine risk that this data has been accessed by quite a few people. And that it could be stored in various parts of the world, including Russia, given the fact that, you know, the professor who was managing the data harvesting process was going back and forward between the U.K. and to Russia," Christopher Wylie said on NBC News' "Meet the Press." Wylie was referring to Aleksandr Kogan, whose company, Global Science Research, harvested Facebook's data using a personality app, according to officials.

The European Union says that Facebook has told it that up to 2.7 million people in the 28-nation bloc may have been victim of improper data sharing involving political data-mining firm Cambridge Analytica. Now the EU says that it will ask the data protection authorities in its various countries to work together and investigate the site for the abuse of data. As the data sharing scandal has spread, estimates of the number of people caught up in it have increased. This week, Facebook said that at least 87 million people across the world had been affected by it. Many of those people are outside of Europe.

WASHINGTON – Investigators on two congressional panels are looking into whether Russia acquired the data of millions of Facebook users and if companies with ties to then-2016 Republican election candidate Donald Trump's campaign played any role in providing it, three sources familiar with the inquiries said. On Tuesday, Facebook said it had deleted 70 Facebook accounts, 138 Facebook pages and 65 Instagram accounts that it said were "controlled" by the Internet Research Agency (IRA), a Russian propaganda arm based in St. Petersburg. Last September, Facebook disclosed that it had suspended about 470 "inauthentic accounts" that it believed were "likely operated out of Russia" and had purchased 3,000 ads which "appeared to focus on amplifying divisive social and political messages." And on Wednesday, the social media platform said the personal information of up to 87 million users, mostly in the United States, may have been improperly shared with political consultancy Cambridge Analytica, up from a previous news media estimate of more than 50 million. Chief Executive Officer Mark Zuckerberg will testify on April 10 and 11 to Congress.

Understanding a customer’s personal opinion is extremely important to initiate and maintain a meaningful conversation. In this paper, we propose an approach to extract latent emotional beliefs of customers and use them to tailor a chatbot’s conversation. We present a machine learning based mechanism to process customer complaints and extract sentiments like customer is sad, happy, upset, etc. Further, we also train a model that extract more fine grain sentiments like the customer is irritated, harassed etc. in context of a particular complaint scenario. This information helps to tailor the dialog according to customer’s emotional state and hence improve the overall effectiveness of the dialog system.
