Google moves to demote fake news
Following increasing incidents of fake news and other flaws, Google is updating its algorithms and demoting misleading and offensive content in its search results. Algorithms will prioritise more “authoritative” content eg. affiliation with a university or verified news site and the quality of sites that link to the site in question. Users can now use a feedback button to report offensive and false results, including offensive autocomplete results that appear as you type in the search box.
China is creating an online encyclopedia
Known as the ‘Chinese Encyclopedia’, the national encyclopedia will go online in 2018. Twenty thousand scholars from universities and research institutes will contribute articles in more than 100 disciplines with 300,000 entries of 1 000 words each. These will showcase China’s science and technology developments, promote historical and cultural heritage and strengthen the core values of socialism. The goal isn’t to mimic Wikipedia, which is blocked in China (though internet giant Baidu has its own online encyclopedia). “We have the biggest, most high-quality author team in the world. Our goal is not to catch up, but overtake” (Yang Muzhi, editor). China has the world’s largest internet population (720 million users) and some of the world’s most restrictive internet laws. The ‘Great Firewall of China’ is the world’s most most sophisticated censorship tool, blocking ‘unsavoury’ parts of the internet.

Mark Zuckerberg said Facebook wants to respond quickly when someone needs help or when an unacceptable post needs taking down.

Amazon will offer “extreme convenience” and goods could be delivered within an hour of ordering online. Amazon Marketplace, for third-party retailers, will launch this year. Amazon is currently searching for a huge logistics facility.
