Most people don't know about Facebook's invasive data practices, study finds

The Independent

Three quarters of Facebook users are unaware that the social network lists their personal interests and traits for advertisers, according to new research. A study published by Pew Research Center revealed the scale of Facebook users' ignorance when it comes to how the tech giant uses their data to make money. Facebook consistently claims that it is transparent in its data collection practices, making it possible for people to find out how its algorithm categorises their interests via the'Your ad preferences' page. But the research suggests that most users are unaware of this. In a survey of 963 US adults, 74 per cent said they did not know Facebook maintained lists of their interests and 51 per cent said they are not comforable with Facebook compiling this information.


Deloitte: Agencies Could Use Natural Language Processing to Derive Insights From Unstructured Data

#artificialintelligence

A Deloitte article says government agencies seeking to generate insights from unstructured data to facilitate the decision-making process and policy analysis could use artificial intelligence in the form of natural language processing. NLP has seven technical capabilities that could help agencies identify patterns, analyze public opinion and categorize topics, according to the article published Wednesday. Those capabilities are topic modeling; text categorization; text clustering; information extraction; named entity resolution; relationship extraction; and sentiment analysis. NLP could help address several issues across defense and national security, health care, energy and financial services domains and those issues include analyzing public feedback and improving regulatory compliance and predictions. The article cited how the Defense Advanced Research Projects Agency uses NLP in the Deep Exploration and Filtering of Text program to glean insights from data.

Twitterature: Mining Twitter Data

#artificialintelligence

I'm back this semester as a DH Prototyping Fellow, and together, Alyssa Collins and I are working on a project titled "Twitterature: Methods and Metadata." Specifically, we're hoping to develop a simple way of using Twitter data for literary research. The project is still in its early stages, but we've been collecting a lot of data and are now beginning to visualize it (I'm particularly interested in the geolocation of tweets, so I'm trying out a few mapping options). In this post, I want to layout our methods for collecting Twitter data. Okay, Alyssa and I have been using a python based Twitter scraping script, which we modified to search Twitter without any time limitations (the official Twitter search function is limited to tweets of the past two weeks).



Research: Some Android apps share your data with Facebook without consent

Mashable

A worrying number of popular Android apps share user data with Facebook without user consent, new research from Privacy International shows (via Financial Times). Here's the worst part: Staying off Facebook doesn't protect you from this. Privacy International, a London-based charity that focuses on improving people's personal privacy, examined 34 popular Android apps, each installed from 10 to 500 million times, between August and December 2018. All of these apps share data with Facebook through its SDK (software development kit), which is fine if the users have in some way consented to this. But the organization intercepted data as it was sent (using a freely available, open-source tool) and found that at least 20 of these apps (roughly 61 percent) "automatically transfer data to Facebook the moment a user opens the app."

Why Are We So Surprised by Facebook's Data Scandals?

WIRED

Surveying the reactions to the latest revelation that Facebook played fast and loose with user data, it was hard not to harken back to what Scott McNally, the founding CEO of Sun Microsystems, told a group of reporters, including one from WIRED, in 1999: "You have zero privacy anyway. McNealy was widely excoriated for candor, but nearly twenty years later, we appear to be not only fighting the same fight but continually shocked that McNally's words, so jarring then, remain so true now. Zachary Karabell is a WIRED contributor and president of River Twice Research. This past spring, when it was revealed Facebook allowed campaign data-mining firm Cambridge Analytica to target users, it was grandly described as "Facebook's Privacy Crisis." When Facebook disclosed in September that hackers accessed the data of 30 million Facebook users, the massive breach that threw the public into a panic, prompting Facebook to assure the masses with messages that "Your privacy and security are important to us."


Is Facebook finished? 'We're not far from Zuckerberg getting subpoenaed', privacy expert says

The Independent

Even for a company as serially scandalous as Facebook, it's been a bad week for the social network. Separate investigations revealed that Facebook gave more than 150 firms access to people's private messages, while also making it impossible for users to avoid location-based ads. After months of fallout from the Cambridge Analytica scandal, US prosecutors also finally got around to filing a lawsuit against Facebook for its data sharing practices. Individually, none of these would likely be enough to bring Facebook down, but some experts believe that, collectively, this could signal the end for the internet behemoth. David Carroll, an associate professor at Parsons School of Design in New York, said this week may finally have dealt Facebook its "knockout" blow.
