How Facebook Could Give Its New Search the Edge

 

The company’s search
engine will become
formidable when it includes
[5] the text of comments and the
vast store of Open Graph
data about things outside
Facebook.
Facebook’s new Graph Search—a feature that lets you
[10] search through the data shared by your friends—clearly
needs some work. It relies solely on the “likes,” checkins,
and profile data provided by your friends – signals
that may be incomplete or unreliable unless you have
friends all over the world who always faithfully check in
[15] wherever they go, and like products and brands honestly,
not ironically. What’s more, queries must be structured
in a way that often makes you feel like you’re talking to
a database.
Fortunately for Facebook, help is on its way. The social
[20] networking giant has two valuable data stores that it
has yet to connect up to its prominent new search box
(so large that it displaces the company’s logo). Accessing
these data stores could change how people find
information online—not to mention the fortunes of arch
[25] rival Google.
Facebook’s search tool has yet to move outside the social
network’s own borders (and into Google’s territory) by
tapping into the Open Graph, a system developed by
Facebook in 2010 as a way for it to understand the
[30] products, services, or other entities described on Web
pages and in mobile apps. Open Graph allows
Facebook to understand, for example, the artist, song,
and album you are interacting with each time you click
a song in a music service such as Spotify. That kind of
[35] knowledge could help Facebook search apply to more
than just content from your friends.
These improvements were mentioned in a brief note at
the end of last week’s launch, but the company has not
said how soon they might arrive. But it is possible to
[40] predict what they might allow. A mostly overlooked
upgrade made by Facebook’s partner Microsoft to its
Bing search engine last week, which lets you search

the text of friends’ Facebook postings, provides a preview
of how the first change might make Graph Search more
[45] useful. Enter “Friends who like tequila” into Graph
Search today and you’ll find only people who have joined
groups dedicated to the drink. Connect your Facebook
account to Bing and type “tequila” into its new “Friends’
photos” search and you’ll find every photo that mentions
[50] tequila in a caption or a comment—so you’ll probably
see a lot more images of people enjoying the beverage.
Facebook’s other untapped resource, the Open Graph,
could also improve its power to recommend products—
and hence offer new opportunities to position ads next
[55] to search results, as Google does. Folding it into Graph
Search would also be a significant shift for Facebook,
and it could change the way we use the Web.
The Open Graph is already big. Last year, entrepreneur
Matthew Berk used five billion Web pages provided by
[60] the nonprofit Common Crawl to show that the Open
Graph describes some 400 million objects (he also
found that 22 percent of the Web’s pages link to
Facebook in some way). Publishers would likely redouble
their efforts to embrace the Open Graph if it were
[65] included in Facebook’s search, Berk predicts, making
it an even more powerful index of what people care
about online. “People used to go out of their way to
make it so that Google would find their content; now
they look to Facebook,” he says. “It’s like a redistribution
[70] of wealth.” Berk’s research into the Open Graph led
him to found a startup called Lucky Oyster, a service
due to launch this year where people can explicitly share
and recommend products and content to Facebook
friends.
[75] “The big shift is to information being about things in
the world and people, not just Web pages,” says Berk.
“At Google, you can see that social has become number
one across the board.”

Assinale a alternativa correta.

Are you

having a heart attack?

 

  How can you tell if you are having a heart attack, stomach indigestion, or simply arthritis pain? There are definite early warning signs and symptoms of heart attacks. Women can experience all, some, a few, or none of these symptoms. Only examination by a doctor, who will administer an electrocardiogram (EKG) and/or a blood test, can confirm if you are having or have experienced a heart attack.

  Each woman will present with different symptoms of a heart attack. Some women experience several symptoms while others show all symptoms. There are women who show no symptoms before their heart attack. The sooner you can recognize your symptoms and take appropriate actions, the better.

  The symptoms to be aware of:

  Discomfort, tightness, uncomfortable pressure, fullness, squeezing, in the center of the chest lasting more than a few minutes, or comes and goes;

  Crushing chest pain;

  Pressure or pain that spreads to the shoulders, neck, upper back, jaw, or arms;

  Dizziness or nausea;

  Clammy sweats, heart flutters, or paleness;

  Unexplained feelings of anxiety, fatigue or weakness - especially with exertion;

  Stomach or abdominal pain;

  Shortness of breath and difficulty breathing;

  Some women mistakenly think only crushing chest pain is a symptom of a heart attack and, therefore, delay seeking medical care. Others have found that healthcare providers have failed to recognize their heart attack symptoms by attributing the cause of symptoms to other health problems, such as indigestion. This is why it is so important to insist that the doctor or nurse administer an EKG test or an enzyme blood test to see if you are having a heart attack. Don't be shy - it's your heart and your life!

"… therefore, delay seeking medical care."

The synonyms for delay and seeking are:

Walk-to-burn-calorie menu 'diet aid'
By Michelle Roberts Health editor, BBC
News online
24 April 2013 Last updated at 10:03 GMT

 

“A quarter-pound double cheeseburger takes a woman about two hours to walk off and a man slightly less”

Menus displaying the exercise needed to burn calories in meals can help people consume less, a US study suggests.

 

Diners given this extra information ordered and ate less calorific food than other customers, a team at Texas Christian University found.
Knowing it takes two hours of brisk walking to burn off a cheeseburger may be more of a warning than being told how many calories it contains, the researchers say. They now plan larger trials.
Researchers Dr Meena Shah and Ashlei James divided 300 volunteers aged 18 to 30 randomly into three groups.
One received a menu without any calorie information, another menus with the calories displayed, and the third menus that showed both calories and the amount of exercise needed to burn them off. All of the menus offered the same choice of food and drink, which included burgers, sandwiches, salad, chips, soft drinks and water.

None of the volunteers was aware of the reason for the study and the researchers took into account hunger levels when interpreting their findings. The group given the menus with the extra information about how much brisk walking would be needed to burn off the food ordered and ate much less than the group who had menus with no calorie information.

They consumed 100 fewer calories, on average, as a result. Dr Shah said: "This is the first study to look at the effects of displaying minutes of brisk walking needed to burn food calories on the calories ordered and consumed.

"This study suggests there are benefits."The researchers say brisk walking is something nearly everyone can relate to.

Calorie counting

"We can't generalize to a population over age 30, so we will further investigate this in an older and more diverse group," Dr Shah added.

They will present their findings at the Experimental Biology 2013 meeting in Boston.

Victoria Taylor, senior dietician at the British Heart Foundation, said clearly sign posting healthy options and nutritional content helped people make informed choices when ordering food.But she added: "While displaying the amount of exercise needed to burn calories is an interesting idea, there's more to a hearthealthy diet than calorie counting.

"Restaurants can also take steps to make meals healthier by serving appropriate portion sizes and reducing the amount of salt, saturated fatand sugar in their dishes.

"Whether eating at home or dining out, a balanced diet with plenty of fruit and veg is the best way to protect your heart."
