Graph-based Topic Extraction from Vector Embeddings of Text Documents: Application to a Corpus of News Articles

arXiv.org Artificial Intelligence

Production of news content is growing at an astonishing rate. To help manage and monitor the sheer amount of text, there is an increasing need to develop efficient methods that can provide insights into emerging content areas, and stratify unstructured corpora of text into `topics' that stem intrinsically from content similarity. Here we present an unsupervised framework that brings together powerful vector embeddings from natural language processing with tools from multiscale graph partitioning that can reveal natural partitions at different resolutions without making a priori assumptions about the number of clusters in the corpus. We show the advantages of graph-based clustering through end-to-end comparisons with other popular clustering and topic modelling methods, and also evaluate different text vector embeddings, from classic Bag-of-Words to Doc2Vec to the recent transformers based model Bert. This comparative work is showcased through an analysis of a corpus of US news coverage during the presidential election year of 2016.


As government looks to regulate Facebook and Instagram, it starts a fight that could decide how we live

The Independent - Tech

There has, for years, been one thing that just about all of the tech industry agrees on: regulation is coming. Recently, they have even realised that it's necessary. But if there is one thing that has split tech behemoths, politicians and the public apart more than perhaps any other issue, it's what that regulation should look like. Now the UK government thinks it has alighted on an answer, offering perhaps the first comprehensive attempt to limit the harm that technology companies are doing to the people – in particular the children – who use them. For the most part, the solution they have chosen focuses on shifting the responsibility for content that appears on the site onto the people who run them.


Huawei addresses spy concerns to UK government

The Independent - Tech

Tech giant Huawei's president has denied the firm has any links to Chinese spying operations. In a letter to the House of Commons Science and Technology Committee, the firm's president Ryan Ding insisted the firm was not involved with such practices. But a 2012 US House Intelligence Committee report outlined Huawei's links to the Chinese state, has since been picked up by other western governments, including Australia, Germany and the UK. FBI Director Christopher Wray has also suggested that the company's smartphones could be used to "maliciously modify or steal information." But Mr Ding insisted that Huawei had never and would never assist any country in gathering intelligence on other countries.


Parents will 'go without' so kids get latest tech gadgets, study claims

The Independent - Tech

More than half of parents struggle to keep up with the costs of the latest technology for their kids, it has emerged. Of 2,000 parents polled, one third admitted "going without" themselves in order to buy the latest products for their children. The study also found 37 per cent save all year to ensure their little ones have the same high-tech gadgets as their mates. How technology brought the #MeToo movement to India Over 75% of grandparents'learn about technology from grandchildren' Technology transforms how dogs sniff out poached African ivory But while eight in 10 parents feel'under pressure' to make sure their kid has the latest technology, seven in 10 have refused to buy brand new due to the sky-high price tags. And 38 per cent have opted for refurbished kit instead.


UK government developing flying 'killer robots', investigation reveals

The Independent - Tech

The UK government is actively funding the development of flying "killer robots" despite publicly stating it has no plans to develop them, a study claims. Research into fully autonomous drone weapons by the campaign group Drone Wars UK revealed the UK's Defence and Security Accelerator (Dasa) is funding research for developing weapons able to kill without direct human input. The report, titled Off the Leash: The Development of Autonomous Military Drones in the UK, highlighted the Taranis drone, which is capable of autonomously flying, plotting routes and locating targets. Uber has halted testing of driverless vehicles after a woman was killed by one of their cars in Tempe, Arizona. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph The giant human-like robot bears a striking resemblance to the military robots starring in the movie'Avatar' and is claimed as a world first by its creators from a South Korean robotic company Waseda University's saxophonist robot WAS-5, developed by professor Atsuo Takanishi and Kaptain Rock playing one string light saber guitar perform jam session A man looks at an exhibit entitled'Mimus' a giant industrial robot which has been reprogrammed to interact with humans during a photocall at the new Design Museum in South Kensington, London The Jaguar I-PACE Concept car is the start of a new era for Jaguar.


Charged EVs New UK law supports public charging and autonomous vehicles

#artificialintelligence

Many federal and state governments around the world have taken measures to encourage EV adoption, but only a few have crafted comprehensive policies that envision a complete transition to electromobility. One of those is of course California, which subsidizes several flavors of charging infrastructure and has funded pilot projects to electrify everything from buses to trucks to off-road commercial vehicles. Another is the UK, which has announced its intention to phase out fossil fuel vehicles by 2040, and recently unveiled a detailed 46-point plan to manage the transition. Part of that effort is the Automated and Electric Vehicles Act, which recently passed through Parliament to become law. The AEV Act gives the government new powers to ensure that motorway service locations are upgraded with plenty of charging points, and allows mayors to request that fuel retailers in their areas install charging infrastructure.


UK revenge porn helpline 'to close' in March due to government cuts, says Labour MP

The Independent - Tech

The UK's revenge porn helpline is set to close next month, according to Labour MP Sarah Champion. The helpline, which launched in February 2015, offers support to men and women affected by revenge porn, where explicit images or videos of them have been shared without their consent. Speaking in the House of Commons today, Ms Champion, the Labour MP for Rotherham, asked why the government was cutting funding for the helpline. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph. The giant human-like robot bears a striking resemblance to the military robots starring in the movie'Avatar' and is claimed as a world first by its creators from a South Korean robotic company Waseda University's saxophonist robot WAS-5, developed by professor Atsuo Takanishi and Kaptain Rock playing one string light saber guitar perform jam session A man looks at an exhibit entitled'Mimus' a giant industrial robot which has been reprogrammed to interact with humans during a photocall at the new Design Museum in South Kensington, London Electrification Guru Dr. Wolfgang Ziebart talks about the electric Jaguar I-PACE concept SUV before it was unveiled before the Los Angeles Auto Show in Los Angeles, California, U.S The Jaguar I-PACE Concept car is the start of a new era for Jaguar.


Everyone who can now see your entire internet history, including the taxman, DWP and Food Standards Agency

The Independent - Tech

Organisations including the Food Standards Agency and the Department for Work and Pensions will be able to see UK citizens' entire internet browsing history within weeks. The Investigatory Powers Bill, which was all but passed into law this week, forces internet providers to keep a full list of internet connection records (ICRs) for a year and to make them available to the Government if asked. Those ICRs in effect serve as a full list of every website that people have visited, rather than collecting which specific pages are visited or what's done on them. Those include expected law enforcement organisations such as the police, the military and the secret service, but also includes bodies such as the Food Standards Agency, the Gambling Commission, councils and the Welsh Ambulance Services National Health Service Trust. The full list of agencies that can now ask for UK citizens' browsing history, which is laid out in Schedule 4 of the Bill and was collected by Chris Yiu, is below: The giant human-like robot bears a striking resemblance to the military robots starring in the movie'Avatar' and is claimed as a world first by its creators from a South Korean robotic company Waseda University's saxophonist robot WAS-5, developed by professor Atsuo Takanishi and Kaptain Rock playing one string light saber guitar perform jam session A man looks at an exhibit entitled'Mimus' a giant industrial robot which has been reprogrammed to interact with humans during a photocall at the new Design Museum in South Kensington, London Electrification Guru Dr. Wolfgang Ziebart talks about the electric Jaguar I-PACE concept SUV before it was unveiled before the Los Angeles Auto Show in Los Angeles, California, U.S The Jaguar I-PACE Concept car is the start of a new era for Jaguar.


Hackers could cause road traffic collisions by taking over electric scooters

The Independent - Tech

Hackers could have used a vulnerability in electric scooters to cause road traffic collisions, researchers have revealed. They found a number of "critical" security flaws in a popular type of self-balancing electric scooter – also widely known as a'hoverboard' – that could let criminals remotely take control of one, even if it was being driven at the time. If they wanted to, they could throw the rider off by making it come to an abrupt stop, or even drive it into traffic. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph. The giant human-like robot bears a striking resemblance to the military robots starring in the movie'Avatar' and is claimed as a world first by its creators from a South Korean robotic company Waseda University's saxophonist robot WAS-5, developed by professor Atsuo Takanishi and Kaptain Rock playing one string light saber guitar perform jam session A man looks at an exhibit entitled'Mimus' a giant industrial robot which has been reprogrammed to interact with humans during a photocall at the new Design Museum in South Kensington, London Electrification Guru Dr. Wolfgang Ziebart talks about the electric Jaguar I-PACE concept SUV before it was unveiled before the Los Angeles Auto Show in Los Angeles, California, U.S The Jaguar I-PACE Concept car is the start of a new era for Jaguar.


'Petya' cyber attack worse than WannaCry hack that crippled NHS, says expert

The Independent - Tech

The'Petya' cyber attack currently spreading around the world could be "bigger" than WannaCry, a cyber security expert says. The ransomware initially hit Ukraine, but the WPP has confirmed that several of its companies have also been affected by it. Naturally, comparisons are being made with WannaCry, the ransomware that so badly affected the NHS in May, but some believe Petya could be worse. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph.
