Researchers working on social media 'lie detector'

LONDON: University researchers are working on a system that could quash rumors spreading on social media by identifying whether information is accurate.
Five European universities, led by Sheffield in northern England, are cooperating on a system that could automatically identify whether a rumor originates from a reliable source and can be verified.
The researchers said Tuesday they hope the system will allow governments, emergency services, media and the private sector to respond more effectively to claims emerging and spreading on social media before they get out of hand.
The three-year, European Union-funded project, called PHEME, is an attempt to filter out the nuggets of factual information from the avalanche of ill-informed comment on Twitter and Facebook.
"Social networks are rife with lies and deception," the project leaders said in a statement. Such messages can have far-reaching consequences, but there is so much of it that it is impossible to analyse it in real time.
Claims during the 2011 riots in London that the London Eye observation wheel was on fire or that all the animals were let out of London Zoo were given as examples of false rumors that spread rapidly via the Internet.
The research is being led by Dr Kalina Bontcheva of Sheffield University's Faculty of Engineering.
"The problem is that it all happens so fast and we can't quickly sort truth from lies," she said.
"This makes it difficult to respond to rumors, for example, for the emergency services to quash a lie in order to keep a situation calm. Our system aims to help with that, by tracking and verifying information in real time."
The project is trying to identify four types of information -- speculation, controversy, misinformation, and disinformation -- and model their spread on social networks.
It will try to use three factors to establish veracity: the information itself (lexical, syntactic and semantic); cross-referencing with trustworthy data sources; and the information's diffusion.
The results can be displayed to the user on screen.
"We can already handle many of the challenges involved, such as the sheer volume of information in social networks, the speed at which it appears and the variety of forms, from tweets, to videos, pictures and blog posts," said Bontcheva.
"But it's currently not possible to automatically analyse, in real time, whether a piece of information is true or false and this is what we've now set out to achieve."
The Times newspaper said the EU would meet most of the predicted 4.3 million euros costs of the project and a final version is hoped for within 18 months.
The project is a collaboration between five universities -- Sheffield, King's College London, Warwick in England, Saarland in Germany and MODUL University Vienna -- and four companies - ATOS in Spain, iHub in Kenya, Ontotext in Bulgaria and swissinfo.ch.

Saudi team develops payload for use in joint lunar exploration with Chinese Space Agency

  • The joint exploration is in line with a memorandum of understanding concluded between China and Saudi Arabia during King Salman's visit to Beijing in mid-March 2017,
  • Under the agreement, the Saudi side will build a payload for a space censoring system for use in filming and take photos of the moon.

JEDDAH: Saudi engineers and researchers have completed work on a payload for a Chinese space vehicle that will explore the moon, the Saudi Press Agency reported on Monday.
The joint exploration is in line with a memorandum of understanding concluded between China and Saudi Arabia during King Salman's visit to Beijing in mid-March 2017, the SPA said, quoting Prince Turki bin Saud bin Mohammed, president of King Abdulaziz City for Science and Technology (KACST).
The joint venture intends to study and explore the moon, "particularly the invisible side of it to provide scientific data for researchers and specialist in space research and science."
As agreed upon by the KACST and the Chinese Space Agency, the Saudi side will build a payload for a space sensory system for use in filming and take photos of the moon.
"The payload was readied in a record time of no more than 12 months during which the Saudi research team faced numerous challenges, most prominent of which was the importance of manufacturing a compact payload with a high capacity of less than 10.5 cu.cm and a weight of no more than 630 grams on the Chinese satellite," the KACST head said.
The payload consists of photographic and data processing units, among others, that is not only light in weight but also able to endure the space environment.
The equipment is capable of taking photos from different angles and altitudes that varies according to the lunar orbit changes, Prince Turki was quoted by the SPA as saying.
"Saudi Arabia's taking part in this great event would boost, no doubt, its efforts to develop its satellite technologies and use it in several fields of reconnaissance and distance censoring as well as space telecommunications, in addition to proceeding with the march of catching the world race in this field," he said.
