World Expositions Can Benefit or Haunt Host Cities

PARIS — Few visitors to Disneyland have a world exposition on their minds as they embark on the 15-minute “It’s a Small World” boat ride. But it was for the 1964 New York World’s Fair, as the expo was known, that Walt Disney designed the ride.

The Eiffel Tower and the Atomium in Brussels are other legacies of the world expos that have showcased technology, architecture and culture every five years since London’s inaugural Great Exhibition of the Works of Industry of All Nations in 1851.

Today, though, hosting an expo means much more than buildings. Bidders count on an economic boost and a higher international profile as benefits from staging the six-month event. “An expo marks a certain ‘coming of age’ for a city,” Urso Chappell, an expo historian, said. “It can aid a city’s physical redevelopment as well as the nation’s image abroad.”

Jobs are created as large construction projects get under way, and international and local tourism increases, a boon to restaurants, hotels, car rental agencies and other businesses. Dubai, for instance, which is in the running for host of the 2020 expo, expects more than 25 million visitors and 270,000 new jobs if it wins.

At the same time, expo organizers have to balance cost and legacy.

The Shanghai World Expo 2010, for example, cost the equivalent of $4.2 billion, according to government figures. But the Chinese news media have reported that the actual cost of staging the event was more than $50 billion — exceeding what was spent on the Beijing Olympics in 2008.

The Shanghai Expo has also left a number of buildings that proved useless after the event and were abandoned. Some, like Germany’s pavilion, were razed.

The hosts of the next world expo, which will be in Milan in 2015, hope to avoid the same fate by “organizing a totally sustainable event and building the country pavilions with eco-friendly materials which, if necessary, can be easily dismantled at the end,” said Giuseppe Sala, chief executive of Expo 2015, which is developing the event.

One of the few things that will remain after the Milan Expo will be a large park. The organizers say plans call for 56 percent of the site to remain “green” after the event. At $1.7 billion, the projected investment by the Milan Expo would also be much smaller than Shanghai’s.

With a reasonable budget and a sound legacy plan, a world’s fair can become a transformative opportunity for a city, and even for a country, expo officials say.

“For the hosts, expos are a key part of a strategic plan for urban development and act as catalysts for accelerating infrastructural transformations,” said Vicente Gonzalez Loscertales, secretary general of the Bureau of International Expositions in Paris, which chooses the host cities and supervises the events. “At the same time, the expo has more intangible but equally powerful impacts on the branding of the city and of the country, and on their international image.”

It is exactly that “unique P.R. opportunity,” as Mr. Gonzalez Loscertales calls the expo, that the 2020 bidders — in addition to Dubai, Izmir, Turkey; São Paulo, Brazil; and Yekaterinburg, Russia, are seeking the event — hope to exploit.

Dubai, which would be the first host of a world’s fair in the Middle East, has emerged as the front-runner, offering the most financial and governmental support. Political tensions in Russia, most recently over what is viewed as an antigay law, and in Turkey could hurt the chances of Yekaterinburg and Izmir. São Paulo, the largest city in the Southern Hemisphere, is seen as least likely to succeed when the 100 or so delegates of the exposition bureau’s General Assembly vote in November, people with knowledge of the bidding said.

The fact that all of the 2020 bidders come from emerging markets is indicative of the changing landscape of international relations. More nations are using such global events to elbow their way onto the world stage. “Shanghai 2010 is a perfect example of an expo held to show that a country is an important international player,” Mr. Chappell said.

Held on the heels of Beijing’s grandiose 2008 Summer Olympics, the expo was the most heavily attended in history, with a record 246 participating countries and organizations and 73 million visitors.

Tjaco Walvis, a branding specialist who researched the impact of previous expos, said an expo “helps to put the organizing city on the mental world map.”

Sometimes, though, the mark it leaves can become a stain. The 1984 Louisiana World Exposition in New Orleans, which had low attendance and financing problems, was forced to declare bankruptcy. It managed to stay open until its closing day only because the United States government provided financial support.

And while expo officials count urban development as a major benefit of hosting, it comes at a cost. In the preparations for the Shanghai World Expo, Chinese authorities demolished thousands of homes and displaced 18,000 families, according to Amnesty International, a human rights group.

Still, if an expo proves a success, the organizers can count on media coverage and international tourism to enhance the host’s image at home and abroad. And countries that participate may benefit as well.

The Dutch pavilion at Expo 2000 in Hanover, Germany, generated about 350 million euros, or $468 million, in indirect long-term economic benefits for the Netherlands, more than 10 times the nation’s investment, according to research by Mr. Walvis, the brand specialist.

A New Tool Aims to Help Facebook Users Dig Deep

But just try finding that photo of Mom and Dad in front of the Eiffel Tower during their 2008 trip to Paris, or the name of that lovely bistro nearby that they mentioned in a status update. Odds are, you would have to plow through a lot of old posts and photos to dig out that information, if you could find it at all.

Now, Facebook is trying to make it easier to find that lost photo or restaurant recommendation and unearth other information buried within your social network with a tool it calls Graph Search.

On Monday, the company will roll out the feature to its several hundred million users in the United States and to others who use the American English version of the site. Other languages will follow.

Developing a sophisticated search feature is vital to Facebook’s long-term success, both to deepen users’ engagement and to make it more appealing to advertisers.

Experts say that Facebook’s technical achievement so far is impressive. Privacy could still be an issue, however, as more user data becomes easily accessible. Also, the feature is dependent on Facebook users volunteering more information about their likes and dislikes.

Ever since Facebook released an early version of the tool in January, the development team has been observing and listening to millions of testers and making improvements. “We launched it early, when it still was in a pretty raw state,” Lars Rasmussen, the engineering director of the project, acknowledged in a recent interview.

Early on, Mr. Rasmussen said, users had trouble even finding the search box, which was blue and melded into the border at the top of every Facebook page. The team eventually made the box white and used words to explicitly describe its purpose.

The tool also has struggled to understand how people actually use language.

For example, typing in “surfers who live in Santa Cruz” confounded the search engine, which was tuned to recognize the phrase “people who like to surf” but not synonyms like surfers or “people who like surfing,” said Loren Cheng, who leads the team of linguists who are working to refine the tool’s natural language capabilities.

The engineers also had to adapt the algorithms to consider the many ways that people express interest in a topic.

For example, Mr. Rasmussen, a ballet fan, said that when he looked for “friends who like ballet,” only two popped up. But many more friends had liked the pages of individual ballet companies. So the search engine now takes into account related pages when assessing whether users like a topic.

Facebook’s Graph Search is still a work in progress, as company officials are quick to acknowledge. Its recognition of synonyms and related topics is spotty. It cannot yet find information in status updates, a top request from users. It does not yet incorporate information from third-party apps like Yelp or Instagram, which is owned by Facebook. And the new search tool is not available on Facebook’s mobile apps, which are increasingly the way that people use the service.

But Facebook believes it is now good enough for wide release. And despite the tool’s limitations, technologists praised the company’s work.

“There is a near infinite variety of ways to say anything in English or in any other language,” said Nick Cassimatis, an associate professor at Rensselaer Polytechnic Institute and a co-founder of SkyPhrase, a start-up working on similar natural-language search technology. “They are trying to memorize all the ways of saying something.”

Unlike Google’s familiar search engine, which typically takes the keywords entered into a search box and matches them to the most relevant Web pages that contain them, Facebook’s search looks primarily at structured data.
