问题     Since the dawn of e-mail, using sarcasm in digital communication has created strife and confusion between friends, colleagues and romantic partners. Sarcasm, after all, is best conveyed using tone of voice, a wink or a nudge.
    Now, as more people are sharing their opinions with casual acquaintances and strangers on social-media sites like Twitter and Facebook—rather than in private text messages to people who know their senses of humor—the sarcasm disconnect is even greater.
    "My work e-mail is down. I’m devastated," or, "because that was so much fun the last time we did it," could mean completely different things to different readers. The confusion has driven some people to create special symbols and characters to clearly mark their snark.
    And woe is the data miner who has the challenge of determining what is sarcasm and what isn’t. Defined as stating the opposite of what is truly meant, sarcasm is proving to be an obstacle for the academics and marketers who create computer programs to analyze massive pools of online chatters to gauge public opinions about products and politicians.
    " Sarcasm is one of the toughest problems in computing," says Shrikanth Narayanan, a professor of computer science, linguistics and psychology at the University of Southern California.
    Computer programming follows strict rules, while natural language, particularly the inside-joke culture of the Web, doesn’t.
    That is the hurdle faced by USC’s Annenberg Innovation Lab, an interdisciplinary center that brings together social and computer scientists. The lab’s "Twitter Sentiment Analysis" project unites linguists, sociologists and computer scientists to try to build a modern-day lexicon for computers to read and interpret huge chunks of data provided by the millions of people who share their opinions online. The scientists at the lab have been using the political season to try to teach a computer to better understand the true sentiment behind tweets.
    " If we can crack through political sarcasm, everything else will be easier," says Jonathan Taplin, a onetime film producer, Bob Dylan tour manager and investment banker who now runs the Annenberg lab, which is sponsored by IBM, DirecTV, Warner Bros, and other companies.
    All data-mining services—or "online sentiment listeners," as they are sometimes called—rely on a combination of natural-language computer programming and human analysts.
    Sentiment listeners and computers are trained to look for cues and symbols such as exclamation marks or emoticons—keyboard characters that, when typed together, convey smiles, winks or other expressions.
    Looking to punctuation and other symbols to signal earnestness can be misleading, says Kate Paulin, the director of the insights and planning department at digital marketing agency 360i. Ms. Paulin says working for brands such as Coca-Cola has taught her that little can be taken at smiley-face value.
    Teens and tweeters use emoticons sarcastically, she says. And a single exclamation mark—as opposed to multiple marks—may actually convey a lack of enthusiasm, she says.
    Lovers of sarcasm who like to tweet are taking matters in their own keyboards. Aliza Licht, the senior vice president of global communications for Donna Karan LLC, who was " devastated" to lose her work e-mail on Tuesday, calls sarcasm "a religion. "Yet, as the hand that controls all of the fashion label’s social outreach—and the popular @ dkny twitter feed—she needs to be sure not to ruffle feathers with her humor.
    So she invented a short, twitter-friendly sign to denote sarcasm—"(*S)"—and uses it to let her followers know when her tongue is in cheek, such as with her tweet about losing e-mail. "We can’t read tonality in text, and it’s a problem," she says.
    When his best friend failed to recognize his use of sarcasm in e-mails about 10 years ago, Doug Sak, an accountant in Washington Township, Mich. , saw a market: He since has created the "SarcMark," an upside-down lowercase E with a dot in the center, helpful for things that might actually not have been " so much fun the last time we did it. " He says he is approaching phone carriers to try to get them to include the symbol in their fonts.
The purpose of the "Twitter Sentiment Analysis" project is to______.
选项 A、bring scientists of different areas to work together
B、compile a dictionary of chunks for people to use online
C、collect and interpret the sarcastic data from the Internet
D、teach a computer to understand political views online
答案C
解析 推理判断题。由题干关键词“Twitter Sentiment Analysis”project定位至第七段。根据该段第二句可知，此项目把语言学家、社会学家和电脑科学家聚集在一起是为了一个共同的目标：为计算机编纂一部当代词典来识别和解读来自网上公众舆论的大量语料数据，因此[C]正确。由上述分析可知，虽然各领域专家聚集在一起，但这是为了达到共同目标的工作方法，而不是目的本身，故排除[A]；虽然也编纂字典，但是该字典是for computers toread…，而不是for people to use online，故排除[B]；由第七段末句可知，科学家想利用这个大选季，搜集大量的公众舆论语料来进行分析，以便让电脑能够识别网上公众舆论背后传递的真实情感，故排除[D]。
