Detecting Fake News Through NLP
Detecting Fake News Through NLPSakha Global Fake news has a negative impact on individuals and society, hence the detection of fake news is becoming a bigger field of interest for data scientists. Attempts to leverage artificial intelligence technologies particularly machine/deep learning techniques and natural language processing (NLP) to automatically detect fake news and prevent its viral spread have recently been actively discussed.
Large technology companies have begun to take steps to address this trend. For example, Google has adjusted its news rankings to prioritize well-known sites and has banned sites with a history of spreading fake news. Facebook has integrated fact checking organizations into its platform.

Fake News Detection using Machine Learning
Fake News Detection using Machine Learningijtsrd Recently, fake news has been incurring many problems to our society. As a result, many researchers have been working on identifying fake news. Most of the fake news detection systems utilize the linguistic feature of the news. However, they have difficulty in sensing highly ambiguous fake news which can be detected only after identifying meaning and latest related information. In this paper, to resolve this problem, we shall present a new Korean fake news detection system using fact DB which is built and updated by human's direct judgement after collecting obvious facts. Our system receives a proposition, and search the semantically related articles from Fact DB in order to verify whether the given proposition is true or not by comparing the proposition with the related articles in fact DB. To achieve this, we utilize a deep learning model, Bidirectional Multi Perspective Matching for Natural Language Sentence BiMPM , which has demonstrated a good performance for the sentence matching task. However, BiMPM has some limitations in that the longer the length of the input sentence is, the lower its performance is, and it has difficulty in making an accurate judgement when an unlearned word or relation between words appear. In order to overcome the limitations, we shall propose a new matching technique which exploits article abstraction as well as entity matching set in addition to BiMPM. In our experiment, we shall show that our system improves the whole performance for fake news detection. Prasanth. K | Praveen. N | Vijay. S | Auxilia Osvin Nancy.

DETECTION OF FAKE ACCOUNTS IN INSTAGRAM USING MACHINE LEARNING
DETECTION OF FAKE ACCOUNTS IN INSTAGRAM USING MACHINE LEARNINGijcsit With the advent of the Internet and social media, while hundreds of people have benefitted from the vast sources of information available, there has been an enormous increase in the rise of cyber-crimes, particularly targeted towards women. According to a 2019 report in the [4] Economics Times, India has witnessed a 457% rise in cybercrime in the five year span between 2011 and 2016. Most speculate that this is due to impact of social media such as Facebook, Instagram and Twitter on our daily lives. While these definitely help in creating a sound social network, creation of user accounts in these sites usually needs just an email-id. A real life person can create multiple fake IDs and hence impostors can easily be made. Unlike the real world scenario where multiple rules and regulations are imposed to identify oneself in a unique manner (for example while issuing one’s passport or driver’s license), in the virtual world of social media, admission does not require any such checks. In this paper, we study the different accounts of Instagram, in particular and try to assess an account as fake or real using Machine Learning techniques namely Logistic Regression and Random Forest Algorithm.

October 16, 2016
Using social media in todays society can be almost unavoidable for many of us but sometimes our personal or private information can be used to represent us for hiring purposes. CareerBuilder’s annual social media survey found that of more than 2,000 hiring managers and HR professionals and more than 3,000 full-time U.S. workers, 60 percent of employers revealed they use social networking sites to research job candidates. Using a candidates’ social media can have disadvantages for recruiters and businesses alike because it can lead to discrimination, basis, or errors based on miss-representations of personal characteristics. With few laws regulating the usage of social media in probing prospective employees, one’s social media, can have a major impact on whether or not a candidate is hired.
Using social media for screening potential candidates for jobs can be extremely risky. While it may have its advantages, employers also enter the risk of learning details about the employee such as if they are pregnant, disabled, their race, religion, and age which could detour them away from hiring an applicant. Throughout the hiring process within companies, many times, employers go to social media to find any information they can on this person. Essentially what these employers do is try to weed out anyone that they find could hurt their company or the environment within. “While much of the information contained on an applicant’s social media page will be benign, information regarding protected characteristics (e.g., religion, disabled status, sexual orientation, marital status, genetic information, etc.) often is prominently displayed in social media” (Morgan & Davis, 2013). Beginning in 2012 and throughout 2013, many states nationwide have passed laws that prohibit employers from requesting personal information that can allow access to a candidate’s personal social sites (Morgan & Davis, 2013). Delaware, Hawaii, Kansas, Maine, Nebraska, New Hampshire, New Jersey, New York, Oregon, Texas, Utah, Vermont, and Washington are a few states that have enforced these laws. There is one state in particular where it is illegal for an employer to screen their applicants through social media and that is Illinois. Screening applicants through social media could also lead to more lawsuits. For example, the University of Kentucky paid $125,000 for a lawsuit where a professor was not given a job because of his views that he expressed about evolution on social media and religious discrimination was the result of screening this applicant on social media. (Ruiz, 2016). In 2013, the Federal level had passed the Social Networking Online Protection Act which is an act that “would prohibit employers, schools and universities from requesting .

Fake News Detection on Social Media using Machine Learning
Fake News Detection on Social Media using Machine Learningclassic tpr For some years, mostly since the rise of social media, fake news has become a society
problem, in some occasions spreading more and faster than the true information. Hence it is
very important to detect and reduce the involvement of fake news in social platforms. This
project comes up with the applications of NLP (Natural Language Processing) techniques for
detecting the 'fake news', that is, misleading news stories that come from the non-reputable
sources. Natural language processing (NLP) refers to the branch of computer science- and
more specifically, the branch of artificial intelligence or AI-concerned with giving computers
the ability to understand text and spoken words in much the same way human beings can.
NLP combines computational linguistics-rule based modelling of human language- with
statistical, machine learning and deep learning models. Together these technologies enable
computers to process human language in the form of text or voice data and to 'understand' its
full meaning, complete with the speaker or writer's intent and sentiment. Only by building a
model based on a count vectorizer (using word tallies) or a (Term Frequency Inverse
Document Frequency) tfidf matrix, can only get you so far. But these models do not consider
the important qualities like word ordering and context. It is very possible that two articles that
are similar in their word count will be completely different in their meaning. The data science
community has responded by taking actions against the problem.
Social Media and Recruiting
Social Media and RecruitingAmber Wherry The document discusses the use of social media in recruiting. It notes that while social media provides benefits like real-time interaction and free posting opportunities, there are also legal and ethical concerns around online profiling and gathering protected applicant information. The document explores how companies currently use social media for tasks like employer branding, targeting candidates, and online profiling. It also examines potential legal issues and provides recommendations, suggesting social media is best used to attract rather than select applicants due to legal risks.
SURENDER SINGH Senior Prosecutor NIA 
SURENDER SINGH Senior Prosecutor NIA Surender Singh This document discusses social media profiling and predictive intelligence. It defines social media profiling as constructing a user's profile using their social media data from platforms like Facebook, Twitter, LinkedIn, etc. This data, including language, location and interests, creates a social profile. Predictive intelligence analyzes current and historical facts to predict future unknown events and is used in marketing, finance, healthcare, crime, and terrorism. The document outlines benefits of social media intelligence analysis like monitoring public opinion, proactive crisis management, and tracking national security information on how terrorists communicate.

Big Data Ethics Cjbe july 2021andygustafson There has been very little analysis of big data ethics from an Ignatian or Catholic Social Thought point of view. The Jesuit tradition, with its focus on persons and community, as well as the CST tradition, certainly provides some direction for navigating these difficult Big Data questions.
Presentation on data privacy group 5
Presentation on data privacy group 5Carla Garcia Font This document discusses data privacy, AI, and social media in recruitment. It begins by defining key terms around data privacy and the General Data Protection Regulation (GDPR). It then examines how recruiters can use social media for sourcing, screening, and evaluating candidates, but also notes potential downsides like discrimination and privacy risks. The document also explores examples of AI being used in recruitment, such as chatbots, candidate sourcing and matching, and personality insights. However, it acknowledges risks of AI like biased algorithms, lack of transparency, and improper access to candidate data without consent. At the end, it poses ethical questions about using AI tools, consenting to data use, and regulating AI in recruitment even if it impacts economic growth

Fake news is rampant, here is how artificial intelligence can help Bernard Marr Artificial intelligence is being used by companies like Logically to help fact-check information and reduce the spread of fake news. Logically uses AI to analyze articles and flag those that need human review. It has reviewed over 1 million articles in India to identify false information. Other companies are also using AI for tasks like identifying the credibility of sources and detecting toxic or deceptive content to help address the large problem of fake news online.

Twitter Based Sentiment Analysis of Each Presidential Candidate Using Long Sh...CSCJournals In the era of technology and internet, people use online social media services like Twitter, Instagram, Facebook, Reddit, etc. to express their emotions. The idea behind this paper is to understand people’s emotion on Twitter and their opinion towards Presidential Election 2020. We collected 1.2 million tweets in total with keyword like “RealDonaldTrump”, “JoeBiden”, “Election2020” and other election related keywords using Twitter API and then processed them with natural language processing toolkit. A Bidirectional Long Short-Term Memory (BiLSTM) model has been trained and we have achieved 93.45% accuracy on our test dataset. We then used our trained model to perform sentiment analysis on the rest of our dataset. With the sentiment analysis results and comparison with 2016 Presidential Election, we have made predictions on who could win the US Presidential Election in 2020 with pre-election twitter data. We have also analyzed the impact of COVID-19 on people’s sentiment about the election.

Five cyber threats to be careful in 2018Ronak Jain It is not true that people are safe from hackers because they only target big companies for money and other purposes. Every person using debit or credit cards, doing online transactions, using the internet can get affected by cyber threats. You may lose money before even recognizing the situation. Simple mistakes from users open the entry for virus and malware coded by hackers.
Your Employees at Risk: The New, Dangerous Realities of Identity Theft
Your Employees at Risk: The New, Dangerous Realities of Identity TheftElizabeth Dimit This document discusses the growing threat of identity theft and how employers can help protect employees. It notes that over 90% of passwords are hackable and criminals are increasingly organized in stealing and selling personal data online. Identity theft comes in many forms and can have serious financial and legal consequences for victims. As such, many employers are offering identity protection services as a benefit to help insulate employees from stress and costs associated with identity theft. The document recommends employers match the type of identity protection offered to the specific risks employees face, such as credit monitoring for financial data or healthcare monitoring for medical information. It then describes the features of one identity protection service called MyIDCare that provides comprehensive monitoring, concierge support services, and assistance recovering from

DevOpsDays Atlanta 2025 - Building 10x Development Organizations.pptxJustin Reock Building 10x Organizations with Modern Productivity Metrics
10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’
Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method we invent for the delivery of products, whether physical or virtual, we reinvent productivity philosophies to go alongside them.
But which of these approaches actually work? DORA? SPACE? DevEx? What should we invest in and create urgency behind today, so that we don’t find ourselves having the same discussion again in a decade?

Fake news detection project
- 1. FAKE NEWS DETECTION Harshda Ghai, Suncity School Pragya Singhal, The Shri Ram School Aravali Ananya Grover, Amity International School, Noida
- 2. How many of you receive forwarded news on Whatsapp?
- 3. How many of you verify each and every piece of news you read before believing it?
- 4. Research shows that 1 in 2 Indians receives fake news via Whatsapp and Facebook As per a survey by Social Media Matters and Institute for Governance, Policies and Politics SO WHY IS IDENTIFYING FAKE NEWS IMPORTANT? Because when we don’t, we can be fooled or manipulated- into worsening existing stereotypes, getting worried about fake disease epidemics, or even influencing whom we vote for.
- 6. How we set up our problem and data ● We input the domain names, HTML codes, and labels (0- true, 1-fake) of 2002 news websites to train the model. ● Then we used 309 examples to test it. The output were labels of either 0 or 1 i.e. real or fake. Under the broad domain on ‘Natural Language Processing’, we used different approaches like keyword search, Bag of Words, and GloVe. ‘Vectors’ of words
- 7. Our best modelA combination of bag-of-words, word-2-vector, and the feature description model was found to be the one which showed us maximum accuracy. ● BAG OF WORDS- looks at the count of each word. ● WORD-2-VEC-finds out the actual meaning of the world ● FEATURE DESCRIPTION- looking at the ‘url’, and the ‘html’ to infer the difference fake and real news.
- 9. To improve: ● Instead of using only 16 features, we changed to using 616 features in our word-2-vec model, which was one of the key factors for improving our accuracy ● Using controversial words which were seen to appear more in fake news than in real. Eg. bombing, terrorist, Trump
- 11. Real-World Applications 1) Elections 2) Fake job rackets 3) Checking the credibility of news links received on Whatsapp , Facebook , Twitter 4) Fake medical news messages
- 12. Case Study-Job rackets Fishing at reputed job portals: Another way of conning job aspirants is through reputed job portals where racketeers fish for personal details of job seekers and exploit them later. "They build a database of critical personal information of unsuspecting candidates which can be dangerously misused at a later point,” says Chakraborty. In June, police arrested three men from Kavi Nagar in Ghaziabad for allegedly cheating several job seekers of around Rs 3.5 crore in the last two years. The mastermind of the racket posed on Naukri.com as representative of fictitious companies such as Idea International and Entomace Technology India Pvt Ltd and posted jobs. He would collect personal data of candidates who applied to those jobs. Later, he would send them fake interview letters from big, well-known companies. He wanted the candidates to pay through Paytm for fixing the interviews so they would get those jobs.
- 13. Real-World Implementation To implement this in real life, we can make a mobile app or a Whatsapp-integrated feature. Users would simply enter the link of a news website and be able to verify whether a news website is true or fake. In the future, our improved model could also consider individual news stories and not just the news website as a whole.
