Code-mixed data is an important challenge of natural language processing because its characteristics completely vary from the traditional structures of standard languages. In this paper, we propose a novel approach called Sentiment Analysis of Code-Mixed Text (SACMT) to classify sentences into their corresponding sentiment - positive, negative or neutral, using contrastive learning. We utilize the shared parameters of siamese networks to map the sentences of code-mixed and standard languages to a common sentiment space. Also, we introduce a basic clustering based preprocessing method to capture variations of code-mixed transliterated words. Our experiments reveal that SACMT outperforms the state-of-the-art approaches in sentiment analysis for code-mixed text by 7.6% in accuracy and 10.1% in F-score.

Legislators, the Federal Trade Commission and other agencies now are considering rules to protect the privacy of users of social networks like Facebook. While those efforts remain in the early stages, even tech companies say privately they expect some regulation to happen down the road. Yet some law-enforcement agencies, including the Federal Bureau of Investigation, and national-security advocates point to a tradeoff, noting that too much privacy can be as bad as too little. Bad actors take advantage of both extremes, abusing access to individuals on networks that are too open or freely conspiring on systems that are too closed. Law-enforcement agencies rely on access to user data as an important tool for tracking criminals or preventing terrorist attacks.

Beyond enhancing robotics and personal devices, emotion AI can be applied in customer experience initiatives, such as VoC programs. A fleet of vendors already offer sentiment analysis by mining billions of data points on social media platforms and user forums.

USA TODAY's Jefferson Graham explains how you can tell Google, Facebook and Amazon to stop following you around the web. LOS ANGELES -- Like many, I downloaded the data this week that Facebook compiled about me over the years, and frankly, it was spooky. I love the social network for showing off my latest photos, staying in contact with old friends and catching up on the latest news. This happened when I joined and Facebook asked if I wanted to connect with other friends by importing my contacts from my computer, which happened to have their phone numbers and sometimes addresses. Facebook has lived with this info since I joined in 2007.

You can request a folder of the things you have uploaded to or shared on Facebook from all your sessions on various devices--plus other curious information--to save on your computer. Once you unzip the folder, open the "index.htm" Right now, you'll see every Facebook friend you've ever had--plus the ones you've gotten rid of. You'll see all your videos, pictures, events, liked pages, private messages and timeline posts. Soon, Facebook will have an improved download tool, and include more information such as posts you've liked, your reactions and comments, even your search and location history. What isn't in this single download is a lot of the behind-the-scenes data that Facebook may use to increase engagement and target ads.

Political data analytics firm Cambridge Analytica still has not deleted the entirety of the Facebook user data it acquired through questionable means in 2015 despite requests that it do so, Channel 4 News reported. According to a new report from the British broadcaster, Cambridge Analytica still maintains a database of personal information and interests pertaining to 136,000 individuals located in the state of Colorado. Cambridge Analytica reportedly has not completely deleted the Facebook data it acquired. It is unclear as to why the political firm is still hanging onto the sizable chunk of data, which purportedly contains a detailed personality and psychological profile for each person. Cambridge Analytica typically uses such information for political advertising campaigns.

You've likely heard by now about Cambridge Analytica, the shadowy, Trump-affiliated data analysis firm that reportedly siphoned off information belonging to 50 million Facebook users, according to The Guardian and Observer, along with The New York Times. In the wake of the scandal over Facebook's privacy practices, users have become newly interested in the data that Facebook collects and retains about them. But while the social network makes it fairly simple to download everything it knows about you, it doesn't provide a roadmap for how to parse that data or figure out what it means. Facebook announced Wednesday, however, that in the coming weeks, it will expand the data it allows you to download to include likes, reactions, search history, and location history. The social network also plans to add an option for users to transfer the data to another service if they want.

Apple boss Tim Cook pulled no punches when he was asked about Facebook's ongoing privacy scandal. Cook was in Chicago on Wednesday to debut Apple's newest iPad and unveil a slew of education-focused apps. When asked what he would do if he were in Facebook CEO Mark Zuckerberg's shoes, Cook replied with a smirk: 'I wouldn't be in this situation.' In an interview with MSNBC and Recode on Wednesday, Tim Cook (pictured) was asked what he would do if he were in Mark Zuckerberg's shoes. He replied: 'I wouldn't be in this situation' Facebook continues to deal with the fallout from its massive data scandal, after it was revealed that 50 million members' data had been harvested without their knowledge.

Facebook will give people new ways of seeing and deleting the data it collects on its users, it has said. The latest development comes as the social network continues to try and stop the damage from the Cambridge Analytica scandal, through which it became clear that the site was collecting many of its users' most sensitive and personal information. Now it says it will add new features in the next few weeks that will change the site's terms of service and its data policy so that people can see how their data is being collected. It will also give people new ways of deleting what has been collected and stopping further information being harvested, it claimed. Those tools will allow people to delete data selectively, as well as removing their account entirely, Facebook's announcement appeared to suggest. "Some people want to delete things they've shared in the past, while others are just curious about the information Facebook has," it wrote.
