New tool to check spread of fake news developed

December 23, 2016

Washington, Dec 22: Scientists have launched a powerful new tool in the fight against the spread of fake news through social networking sites.

fnewsThe tool, called Hoaxy, visualises how claims made in fake news spread online.

"In the past year, the influence of fake news in the US has grown from a niche concern to a phenomenon with the power to sway public opinion," said Filippo Menczer, a professor at Indiana University (IU) in the US.

"We've now even seen examples of fake news inspiring real-life danger, such as the gunman who fired shots in a Washington, DC pizza parlour in response to false claims of child trafficking," said Menczer.

Users can enter a claim into the service's website and see results that show both incidents of the claim in the media and attempts to fact-check it by independent organisations.

These results can then be selected to generate a visualization of how the articles are shared across social media.

The site's search results display headlines that appeared on sites known to publish inaccurate, unverified or satirical claims based upon lists compiled and published by reputable news and fact-checking organisations.

A search of the terms "cancer" and "cannabis," for example, turns up multiple claims that cannabis has been found to cure cancer, a statement whose origins have been roundly debunked by the reputable fact-checking website.

A search of social shares of articles that make the claim, however, shows a clear rise in people sharing the story, with under 10 claims in July rising to hundreds by December.

Hoaxy's visualisations illustrate both temporal trends and diffusion networks as they relate to online claims and fact-checks, said Giovanni Luca Ciampaglia, a research scientist at the IU Network Science Institute.

Temporal trends plot the cumulative number of Twitter shares over time. Diffusion networks show how claims spread from person to person.

Twitter is currently the only social network tracked by Hoaxy, and only publicly posted tweets appear in the visualisations.

"Not all claims you can visualize on Hoaxy are false, nor are we saying that the fact-checkers are 100 per cent correct all of the time," said Menczer.

"Hoaxy is a tool to observe how unverified stories and the fact-checking of those stories spread on public social media. It's up to users to evaluate the evidence about a claim and its rebuttal," he said.

Pune, Jul 24: Agile and dexterous, 85-year-old Shantabai Pawar wields sticks with absolute ease as she displays 'lathi-kathi' on the streets of Pune.

A video of her, displaying her skills in the Indian martial art form for livelihood, has gone viral on social media.

Pawar told media persons that she learnt the art form when she was only eight and has been practising it since then. The ancient martial art s believed to be linked to Dombari community, a nomadic tribe in Maharashtra.

"I have been pursuing the art of lathi-kathi since I was eight. I have never left it. It is part of me and it is an honour to practice it. My father taught me this. He taught me to work hard," Pawar told media persons.

In the video, the sari-clad octogenarian takes a warrior-like stride and effortlessly rotates a stick several times in a second in her hand and around her head and then does it with two sticks together with a smile on her face. She also tosses a stick in the air and catches it with ease.

The assembled gathering is impressed and enthused.

"People come and say, 'Well done Daadi!' I practice it to earn money for my children and grandchildren," she said.

Pawar leaves her home in the morning in the conditions created by coronavirus and performs the art form on roads and streets.

"I go to various areas to perform the art form and people give money," she said.

The artiste also uses thali and stick to gather the attention of people as most of them are indoors due to conditions created by COVID-19.

Senior citizens have been advised against venturing out due to their greater susceptibility to coronavirus but Pawar said she is not afraid to step out.

"People do advise me to not go out due to fear of COVID-19 but I am not scared. Whenever I step out, I pray to my God and he has kept me safe so far," she said.

Aishwarya Kale, a dancer and the person who uploaded the video on social media, said that it is "only an artist who can understand what help another artist needs".

"I was in that area shopping for some items and it was then I saw her performing and thought that I should film her and upload her video on social media. But I never thought that the video would go viral and she would receive financial help not just from people in the country but overseas as well," Kale told media persons.

"She is now getting honour for her craft that she couldn't get in the last 85 years. I feel good that through my small video, her art form has become viral," she added.

New Delhi, Jan 26: Google on Sunday marked India's 71st Republic Day by dedicating a doodle illustrating the country's rich cultural heritage that permeates and unites the diverse nation.

From its world-famous landmarks like the Taj Mahal and India Gate, to the wide array of fauna such as its national bird (the Indian peafowl), to classical arts, textiles, and dances, the doodle, designed by Singapore-based artist Meroo Seth, brings together the rich cultural heritage of the country.

Republic Day marks the completion of India's transition towards becoming an independent republic after its constitution came into effect. The governing document had taken nearly three years of careful deliberation to finalise, and its eventual enactment was joyfully celebrated across the country.

While the Constitution was adopted by the Indian Constituent Assembly on 26 November 1949, it came into effect on January 26 -- a day when Declaration of Indian Independence (Purna Swaraj) was proclaimed by the Indian National Congress back in 1929, as opposed to the Dominion status offered by the British Regime.

Festivities embody the essence of diversity found in one of the world's most populous nations, celebrated over a three-day period with cultural events displaying national pride.

Last year's doodle on Republic Day, designed by artist Reshidev RK, had featured Rashtrapati Bhavan in the background along with a display of the country's iconic monuments and heritage.

Soon, you may be able to withdraw cash from an ATM without touching any part of the machine. AGS Transact Technologies, a provider of cash and digital payment solutions and automation technology, on Monday said it has successfully developed and tested a touchless ATM solution in light of the COVID-19 pandemic.

The ‘contactless' solution, currently under demo at interested banks, enables a customer to perform all the steps required to withdraw cash from an ATM using the mobile app itself. 

The customer simply has to scan the QR code displayed on the ATM screen and follow the directions on their respective bank's mobile application. 

This includes entering the amount and mPIN required to dispense the cash from the ATM machine. 

According to the company, the QR code feature makes cash withdrawals quicker and more secure, and negates the chances of compromising the ATM Pin or card skimming.

"The new Touchless ATM solution is an extension of the flagship QR Cash solution which ensures safety of the users and will provide a seamless cash withdrawal experience with enhanced security," said Ravi B. Goyal, Chairman and MD, AGS Transact Technologies Ltd.

With minimum investment, the banks can enable this solution for their ATM networks by upgrading the existing software.

AGSTTL has so far installed, maintained and managed a network of over 72,000 ATMs across the country and also provides customised solutions to leading banks. 

The company earlier introduced UPI-QR based Cash withdrawal solution in partnership with Bank of India. 

This is how the solution works.

Open the Bank mobile application on your smartphone and select QR Cash Withdrawal. Enter the amount you wish to withdraw on the mobile app and scan the QR code on the ATM screen.

Next, confirm the amount by clicking on ‘proceed' in the app and enter the mPin to authenticate the transaction. Now collect the cash and receipt and you are done.

"The seamless, cardless and touchless withdrawal method is designed to provide easy transaction flow, without the need to touch the ATM screen or enter the pin," said Mahesh Patel, President and Group Chief Technology Officer, AGS Transact Technologies.
