Here's another thing we're doing: During the talks this morning, we've been automatically scraping Twitter for the TED2015 hashtag, and we've been doing an automated sentiment analysis, which means, are people using positive words or negative words or neutral?
下面是我们做的另一个实验： 在今早的演讲中，我们一直在自动的刷取 TED2015主题标签的推特， 一直在做自动的情绪分析， 也就是：人们是用正面，负面还是中性的词 ？
