Censorship Alert! Academic Study Shows Sina Weibo’s Human Censors Are Pretty Darn Fast (techinasia.com)

If you wanted to learn more about Sina Weibo’s censorship patterns, today is your lucky day. A group of computer scientists from Bowdoin College, Rice College, and the University of New Mexico have, along with an independent researcher, released the results of an academic study of Sina Weibo’s censorship practices. The study, which we came across via MIT Technology Review, used “architecture [that could] detect post deletions within one minute of the deletion event,” giving the researchers perhaps the most precise look yet into how quickly Sina’s content team takes down sensitive Weibo posts. The results? Sina is pretty darn fast:
We found that deletions happen most heavily in the first hour after a post has been submitted. Focusing on original posts, not reposts/retweets, we observed that nearly 30% of the total deletion events occur within 5-30 minutes. Nearly 90% of the deletions happen within the first 24 hours.
So Sina’s censors are pretty fast. But what, exactly, are they deleting? Researchers used a variety of analytical tools to look at what content was most quickly deleted, and found that:
The topics where mass removal happens the fastest are those that combine events that are hot topics in Weibo as a whole (e.g., the Beijing rainstorms or a sex scandal) with themes common to sensitive posts (e.g., Beijing, government, China, and policeman).
Researchers also found that, unsurprisingly, users with more total deleted posts tended to get their posts deleted more quickly than other users, suggesting that Sina’s content team was watching their accounts more carefully. The following chart from the study shows the downward trend in post lifetime as a user’s number of total deleted posts increases:

Of course, it’s not all humans doing the deleting. In fact, by the study’s estimations, for an all-human team to censor Weibo, 4,200 team members would be required, assuming each team member could read at the blazing rate of 50 posts per minute. The study points out that as a result of that, weibo’s censorship system has become an incredibly complex system, employing both human and software censors, employing multiple blocked keyword lists that trigger different censorship responses, search filtration systems, and more. (Of course, none of that should come as much of a surprise to longtime weibo users, who have likely experienced many of the different types of censorship on Sina Weibo firsthand).
If you’re really interested in Weibo censorship, the full paper is worth a read, and although it’s a bit dry and quite technical in places, the good news is that it’s only ten pages long.

China faces social, financial risks in urbanization push (Reuters)


BEIJING | Thu Mar 7, 2013

http://www.reuters.com/article/2013/03/07/us-china-parliament-urbanisation-idUSBRE92607K20130307


(Reuters) - China's urbanization drive could fuel social unrest over land disputes and pose financial risks if money is thrown around recklessly, a senior communist party official and a leading economist said on Thursday.
Shifting people from the countryside to cities is a policy priority for China's new leaders as they seek to sustain economic growth that last year slowed to a 13-year low of 7.8 percent. The government hopes 60 percent of China's population of almost 1.4 billion will be urban residents by 2020.
The urban population jumped to above 700 million from less than 200 million in the previous three decades, but that explosion has triggered sometimes violent clashes over expropriation of farmland for development as well as water shortages, pollution and other problems.
"These are severe challenges as we are trying to sustain the urbanization process," said Chen Xiwen, head of the Office of Central Rural Work Leading Group, the top body which guides China's farm policy. "Many people have worries and such worries are understandable," he told a news conference on the sidelines of China's annual parliament session.
The government must protect farmers from losing their land in the process as local governments have been relying heavily on land sales to finance local investment, Chen said. "If the urbanization process becomes a process of depriving and harming farmers' interests, it cannot be sustained and society cannot maintain stability."
SPENDING BINGE
Li Yining, an influential economist at Peking University, warned that China's banks could be dragged into another spending binge that could spark a financial crisis.
"When we talk about urbanization, it seems the whole country is going into mass action to spend heavily ... this could trigger a financial crisis," he told the news conference.
China plans to issue guidelines on urbanization in the first half of this year, the head of the National Development and Reform Commission, the main economic planning agency, said on Wednesday. The commission sees the urbanization rate rising to 53.37 percent this year from 52.57 percent in 2012.
Chinese leaders have pledged to steadily reform the rigid household registration, or hukou, system that could help turn millions of rural workers from savers into consumers.
The hukou system has split China's population along urban-rural lines, preventing millions of Chinese who are registered as rural residents from settling in cities and enjoying basic urban welfare and services.

Chinese Super League switches gear to nurture home-grown talent (AFP)


Super League is eager to put graft scandal as well as Drogba failure behind it with investment in existing and emerging stars

Friday, 08 March, 2013

Despite the echoes of a huge corruption scandal and Didier Drogba's short-lived stay, a sense of cautious optimism pervades long-suffering mainland football as the new season starts this week.
Following last year's failed experiments with Drogba and Nicolas Anelka, blockbuster signings have given way to the more sustainable model of focusing on existing stars and emerging talent.
And pundits say the Chinese Super League (CSL), which gets under way today, looks set finally to make its mark on the international stage and end China's 23-year wait for a continental title.
Ivory Coast international Drogba and former France striker Anelka raised hopes that the cash-rich mainland game was about to hit the big time when they arrived last season. However, both left Shanghai Shenhua in January.
Last year's hype reached its apex when David Beckham was seriously tipped for the CSL. Beckham will appear this year - but only as a paid "ambassador" for the league, a move which received a mixed reaction from fans.

Domestic sides have been noticeably more cautious in the transfer market in the run-up to this season, quietly building their teams around established top names or young Chinese talent.


Many believe the conservative approach, coupled with a renewed attempt to draw a line under the wide-ranging match-fixing probe, whose final punishments were handed out last month, is reason for optimism.
"While Drogba and Anelka leaving is bad, there are many reasons to be positive about the new season," Yan Qiang, vice-president of Titan Media, one of China's leading sports publishers, said. "It is important not to forget that Shanghai Shenhua are just one club in China."
Shenhua will start the season on minus six points, and stripped of their 2003 league title, as punishment for their part in the match-rigging affair, which left 33 players banned and senior officials in jail.
"I have told them that our goal is to avoid relegation. We have to fight each game as a fateful match because we don't have any leeway," said Zhu Jun, Shenhua's colourful owner.
Deep-pocketed Guangzhou Evergrande, managed by World Cup-winning coach Marcello Lippi and staffed by a bevy of foreign stars, will aim to cement their reputation as one of Asia's top sides with their third straight Chinese title.
Last season's double-winners already look in impressive form after they swept aside Urawa Red Diamonds 3-0 in their first AFC Champions League game last week.
Brazilian forward Muriqui and Paraguayan striker Lucas Barrios had star roles against the J-League side, with Guangzhou hotly tipped to become China's first Asian champions since Liaoning in 1990.
Jiangsu Sainty, also in the Champions League, have based their success on home-grown talent, and Serbian coach Dragan Okuka is developing the club's youth strategy as he attempts to build on last year's second place.
Third-placed Beijing Guoan signed former Dalian Aerbin coach Aleksandar Stanojevic hoping that he can get the best out of underperforming former Premier League striker Freddie Kanoute and Ecuadorian Joffre Guerron.
In contrast with last season's headline-grabbing deals, Dalian Aerbin made the most high-profile signing in the mainland top tier, with the addition of French international striker Guillaume Hoarau, 29, from Paris Saint- Germain.
Shenhua, after last year's experiences with Drogba and Anelka, have opted for a different strategy entirely by signing the likes of 40-year-old defender Rolando Schiavi and fellow Argentine Patricio Toranzo, who plays in midfield.
