QUESTION EVERYTHING

Page 16: system 1 google 3011  Can existing Sentiment Analysis tools respond to t

The extent to which content is ‘popular’ is framed by both the availability of that content, the potential audience’s awareness of its availability, and its desirability. Around 70% of shows that are translated are still currently being broadcast, the remaining have ended their run.!

DEFINE “POPULAR”8 HOURS

Page 17: system 1 google 3011  Can existing Sentiment Analysis tools respond to t

As with the torrent scene it is possible to obtain more obscure content, but takes longer to track down, download the original source and pull together a crew to that is sufficiently motivated to translate.!

The most popular shows attract the strongest pool of translation talent – less popular shows and those with longer recording times and more dialog will naturally take longer. 8 hours is the benchmark.!

DEFINE “OBSCURE”8 HOURS

Page 18: system 1 google 3011  Can existing Sentiment Analysis tools respond to t

Most Chinese shows are broadcast with subtitles in standard “Chinese characters to support the hundreds of dialects spoken across China. Translating shows is one way to enjoy, spread their passion, come together as a community and learn English.

DEMAND8 HOURS

Page 19: system 1 google 3011  Can existing Sentiment Analysis tools respond to t

Some shows such as Prison Break are broadcast on state run CCTV years after they’ve been available for download. The official broadcast includes a locally sensitive translation – replacing words e.g. ‘horny’, ‘homo’, ‘sex’, .etc with subtler alternatives.

AUTHENTICITY8 HOURS

Page 20: system 1 google 3011  Can existing Sentiment Analysis tools respond to t

Self-censorship comes into affect for politically sensitive material that would draw the attention of the authorities, although with a few exceptions it is anyway debatable whether this content would meet the criteria of being ‘popular’, certainly compared to local alternatives.

WHAT ISN’T TRANSLATED8 HOURS

Page 21: system 1 google 3011  Can existing Sentiment Analysis tools respond to t

Many people’s motivation to jump the Great Firewall (GFW) through proxies or subscribing to a Virtual Private Network (VPN) is driven by the consumption of porn. !

Facebook, YouTube and Twitter also lie behind the GFW but are niche compared to their local, vibrant Chinese equivilents.

THE GREAT FIREWALL8 HOURS

Page 22: system 1 google 3011  Can existing Sentiment Analysis tools respond to t

In our informal survey of 150 students from 8 Shanghai universities ~19% used proxies, and only ~3% used VPN’s. Not everyone who crosses the GFW to access banned social networks, don’t actively participate, to do so would leave personal trace.

GWF? WTF!8 HOURS
