For the past four decades that basic tension between artificial intelligence and intelligence augmentation (增加)—A.I. versus I.A.—has been at the heart of progress in computing science as the field has produced a series of ever more powerful technologies that are transforming the world.
Now, as the pace of technological change continues to 31 , it has become increasingly possible to design computing systems that enhance the human experience, or now—in a growing number of cases—completely 32 with it.
Watson is an effort by IBM researchers to advance a set of techniques used to process human language. It provides 33 evidence that computing systems will no longer be limited to responding to simple commands. Machines will increasingly be able to pick out jargon (行话) and even riddles. In attacking the problem of the 34 of human language, computer science is now closing in on what researchers refer to as the "Paris Hilton problem"—the ability, for example, to determine whether an 35 is being made by someone who is trying to reserve a hotel in France, or 36 to pass time surfing the Internet.
Traditionally, economists have argued that while new forms of automation may displace jobs in the short run, over longer periods of time economic growth and job creation have continued to 37 any job-killing technologies. For example, over the past century and a half the 38 from being a largely agrarian (农业的) society to one in which less than 1 percent of the United States labor force is in agriculture is frequently cited as 39 of the economy"s ability to reinvent itself.
That, however, was before machines began to "understand" human language. Rapid progress in natural language processing is beginning to 40 to a new wave of automation that promises to transform areas of the economy that have until now been untouched by technological change.
A. abolish F. evidence K. outpace
B. accelerate G. expenditure L. shift
C. ambiguity H. inquiry M. simply
D. bring I. irrational N. striking
E. dispense J. lead O. unanimously

About 2 million jobless Americans fear they"ll lose their extended unemployment benefits, which are slated (计划) to end next month unless Congress votes to renew them. Their concerns make a new finding all the more 1 : Many people eligible for unemployment don"t even bother to collect it. In the depths of the 2 in 2008 and 2009, only half of those who qualified for benefits 3 , a study by the St. Louis Federal Reserve Bank shows.
The portion filing for benefits shot up to 95% in 2010 and 2011, the study says, but that still means about 200000 people didn"t claim money to which they were 4 .
Many unemployed people aren"t eligible for benefits because they worked part-time or weren"t at their jobs long enough, for example. In 2009, about 3 million of the average 14.5 million or so jobless people didn"t qualify for benefits. But of the roughly 11.4 million who were laid off and eligible to collect that year, only about 5.7 million filed 5 , according to Fuller and the BLS. Those who didn"t saved state and federal governments $108 billion— 6 as much as the $121 billion in benefits paid, the study says. That 7 dwarfed the $11 billion in benefit overpayments due to clerical errors or fraud.
The share of people applying for benefits has risen or fallen along with average duration of unemployment. For example, Americans were out of work for an average of 18 weeks in 2008 and 24 weeks in 2009—when only half of those eligible applied. But average joblessness 8 to about 33 weeks in 2010 and 39 weeks in 2011 as the share seeking benefits soared to 95%.
Average jobless duration has 9 near 40 weeks this year. But it should dip to about 37 weeks in 2013, says Mark Zandi, chief economist of Moody"s Analytics. That suggests the portion seeking benefits could 10 slightly.

About 2 million jobless Americans fear they"ll lose their extended unemployment benefits, which are slated (计划) to end next month unless Congress votes to renew them.

That 7 dwarfed the $11 billion in benefit overpayments due to clerical errors or fraud.
The share of people applying for benefits has risen or fallen along with average duration of unemployment. For example, Americans were out of work for an average of 18 weeks in 2008 and 24 weeks in 2009—when only half of those eligible applied. But average joblessness 8 to about 33 weeks in 2010 and 39 weeks in 2011 as the share seeking benefits soared to 95%.

About 2 million jobless Americans fear they"ll lose their extended unemployment benefits, which are slated (计划) to end next month unless Congress votes to renew them.

Many unemployed people aren"t eligible for benefits because they worked part-time or weren"t at their jobs long enough, for example.

But of the roughly 11.4 million who were laid off and eligible to collect that year, only about 5.7 million filed 5 , according to Fuller and the BLS. Those who didn"t saved state and federal governments $108 billion— 6 as much as the $121 billion in benefits paid, the study says. That 7 dwarfed the $11 billion in benefit overpayments due to clerical errors or fraud.
The share of people applying for benefits has risen or fallen along with average duration of unemployment. For example, Americans were out of work for an average of 18 weeks in 2008 and 24 weeks in 2009—when only half of those eligible applied. But average joblessness 8 to about 33 weeks in 2010 and 39 weeks in 2011 as the share seeking benefits soared to 95%.
Average jobless duration has 9 near 40 weeks this year. But it should dip to about 37 weeks in 2013, says Mark Zandi, chief economist of Moody"s Analytics. That suggests the portion seeking benefits could 10 slightly.
