Yelp says quarter of reviews 'fake'

Written By Unknown on Sabtu, 28 September 2013 | 23.53

27 September 2013 Last updated at 12:03 ET

Yelp, the online directory and consumer review site, says a quarter of the reviews it receives could be fake, as businesses increasingly attempt to skew consumers' opinions.

Its automated review filter now "suppresses around 25%" of "suspicious" reviews it receives, the company said.

"Any that are fake will be swiftly filtered out," said a spokesman.

But the company admitted its system was not foolproof, and that some filtered reviews could be genuine.

Last week New York authorities fined 19 firms a total of $350,000 (£218,500) for posting fake reviews on websites.

In a year-long sting operation, the city's attorney-general's office set up a fake yogurt shop in Brooklyn and asked for help from firms offering search engine optimisation (SEO) services that can help boost companies' online presence.

Some of these firms created online profiles and then paid for reviews from freelance writers, some from the Philippines, Bangladesh and Eastern Europe.

Many businesses were also producing their own fake online reviews, the authorities discovered.

The practice is known as "astroturfing", reflecting the fact that such consumer - or grass-root - reviews are not genuine.

Fraudulent

A recent academic report found that the proportion of fake reviews submitted to Yelp had risen from 5% in 2006 to 20% in 2013.

Michael Luca of Harvard Business School and Georgios Zervas of Boston University studied the incidence of fraudulent reviews of Boston restaurants posted to Yelp, including those that had been filtered out.

After analysing more than 310,000 reviews of 3,625 restaurants, they found that negative fake reviews occurred in response to increased competition, while positive fake reviews were used to strengthen a weak reputation or to counteract unflattering reviews.

Fake reviews tend to be extremely positive or negative, they found.

"As crowdsourced information becomes increasingly prevalent, so do incentives for businesses to game the system," the authors concluded.

Yelp, which has more than 100 million unique visitors a month, expressly forbids paid reviews.

About 42 million reviews have been published on Yelp since its launch in 2004.

Yahoo in recycled email privacy row

26 September 2013 Last updated at 07:33 ET By Jane Wakefield Technology reporter

Yahoo email addresses reassigned to a new owner are receiving personal emails intended for the previous owner.

One man told news site Information Week that he had received emails with some highly sensitive information in them.

In June the web firm announced Yahoo addresses and IDs would be reassigned if they had been inactive for a year.

Privacy experts called on Yahoo to address the issue "immediately". Yahoo says it has taken a series of measures to overcome privacy and security fears.

"Before recycling inactive accounts we attempted to reach the account owners [in] multiple ways to notify them that they needed to log in to their account or it would be subject to recycling," a Yahoo representative told the BBC.

"We took many precautions to ensure this was done safely - including deleting any private data from the previous account owner, sending bounce-backs to the senders for at least 30-60 days letting them know the account no longer existed and unsubscribing the accounts from commercial mail."

It is also in the process of rolling out a feature called "Not My Email" where users can report an email that is not intended for them.

The process will come as little comfort to the previous owner of an email account now owned by Tom Jenkins, an IT security professional.

Mr Jenkins told Information Week: "I can gain access to their Pandora account [online radio] but I won't. I can gain access to their Facebook account, but I won't. I know their name, address and phone number. I know where their child goes to school. I know the last four digits of their social security number. I know they had an eye doctor's appointment last week and I was just invited to their friend's wedding."

Other users have revealed that they have also received messages that contain personally identifiable information.

Intimate data

"I recommend logging into your Yahoo account every six months or so in order to ensure that you retain control over it," said security expert Lee Munson.

Privacy experts said that the issues were inevitable.

"These problems were flagged by security and privacy experts a few months ago when Yahoo announced their intention to recycle old emails, and cautioned that Yahoo's plan created significant security and privacy risks. Yahoo downplayed these risks, and ignored critics, but now we see these concerns were legitimate," said Mike Rispoli, spokesman for Privacy International.

"This email recycling scheme, an effort to re-engage old users and attract new ones, is resulting in some of our most intimate data being accessed by someone we don't know and without our knowledge.

"We're talking about account passwords, contacts for friends and families, medical records - this issue needs to be addressed immediately by Yahoo if they care about the privacy of their users and want them to trust the company with sensitive information."

Taxpayers 'ripped off' on broadband

26 September 2013 Last updated at 08:00 ET By Jane Wakefield Technology reporter

The taxpayer is being "ripped off" over the cost of rolling out broadband to rural areas of the UK, MPs have said.

The Commons Public Accounts Committee (PAC) says the government "mismanaged" the project by awarding all 26 rural broadband contracts to BT.

It also said BT had "exploited its quasi-monopoly position" as the main provider.

The government defended the process as fair, while BT said it was "disturbed" by the claims which were "wrong".

'Failed to deliver'

Making sure that those living in the countryside get broadband speeds comparable to those living in towns and cities has long been something the government has grappled with.

Commons Public Accounts Committee chairwoman Margaret Hodge

Public Accounts Committee chairwoman Margaret Hodge said taxpayers had been ''fleeced''

Commercial firms such as Virgin Media and BT see little profit in rolling out services to areas with few people living in them.

So, as an incentive, the government provided a subsidy pot of £230m for firms taking on the task, with an extra £250m available after 2015, and it awarded contracts on a county-by-county basis.

Local authorities are also contributing £730m to the project, bringing the total amount of public funding to £1.2bn.

But only Fujitsu and BT entered the bidding competition, with Fujitsu later withdrawing.

BT has so far been chosen in 26 counties and is expected to win the 18 remaining contracts.

The report by the PAC criticised the government's management of the project: "The Department for Culture, Media and Sport's design of the rural broadband programme has failed to deliver the intended competition for contracts, with the result that BT has strengthened its already strong position in the market."

Continue reading the main story
  • Denmark plans to have 100 megabits per second to all by 2020
  • Estonia wants 100Mbps for everyone by 2015
  • France plans almost universal coverage at 100Mbps by 2020
  • Germany expects to have around 70% coverage at 50Mbps by 2014
  • Greece wants 100% of citizens to have access to 30Mbps by 2020
  • Ireland plans 100Mbps for all by 2020
  • Italy wants to see half of its citizens have access to 100Mbps by 2020
  • The UK's target is 90% coverage by 2017 but at the lower speed of 24Mbps

It said its contract terms were "overly generous" to BT and did not "promote value for money".

It also accused ministers of failing to check whether BT's bids were reasonably priced and said there had been "wildly inaccurate" estimates of costs.

"Local authorities are contributing over £230m more to the programme than the department assumed in its 2011 business case and BT over £200m less, yet BT will ultimately benefit from £1.2bn of public funding," the report said.

Committee chair Margaret Hodge added: "The taxpayer has been ripped off with £1.2bn going to the shareholders of BT.

"If you (the government) had devised it differently, had bigger areas for the contracts so you could spread your costs more, allowed different technologies to be used and insisted on a 100% coverage, we would have found other people in the game and I bet we would have spent less of the taxpayers money."

Media minister Ed Vaizey told BBC Radio 4's Today programme the costs were "not out of control", stressing BT was "putting up more than a third of the costs of rural broadband".

"BT is delivering under our scheme to up to 10,000 homes now; it will deliver to millions of people over the next two years with the best value-for-money, government-sponsored broadband scheme you will pretty much find anywhere in the world."

Culture Minister Ed Vaizey

Culture Minister Ed Vaizey said the broadband programme is ''very good value for money''

He said only BT and Virgin had the infrastructure to roll out the broadband, adding Virgin had not wanted to open their cable up for other companies to use - whereas many companies used BT.

Vodafone said the project would "not deliver value for money nor the rural connectivity that Britain needs", and urged the government to revise the process to encompass wireless 4G.

'Transparent from start'

BT was further criticised in the report for failing to provide local authorities with full information about where exactly it would roll out superfast broadband services, which in turn hampered rivals from drawing up alternatives.

And it was criticised for including a clause in its contract preventing local authorities it dealt with from disclosing the costs involved to other authorities negotiating contracts.

This lack of transparency meant the company "exploited its quasi-monopoly position" to limit access to both the wholesale and retail market "to the detriment of the consumer", concluded the report.

BT said it was disturbed by the report, "which we believe is simply wrong and fails to take on board a point-by-point correction we sent to the committee several weeks ago".

It added: "We have been transparent from the start and willing to invest when others have not.

"It is therefore mystifying that we are being criticised for accepting onerous terms in exchange for public subsidy - terms which drove others away."

It denied it had failed to deliver value for money for the taxpayer and said that, even with the public subsidies, it would take it 15 years to pay back its investment in rural broadband.

"Rolling out fibre is an expensive and complex business," it said.

BT's "point-by-point correction", sent to the committee on 13 August, included 83 comments responding to statements made at a committee meeting a month earlier.

It described many of the comments, on issues from the percentage of households reached to the way the contracts were awarded, as "false" and "misleading".

The report recommended the government should publish BT's detailed rollout plans so other suppliers could offer services to the final 10% of the population that would not be covered under current plans.

It said the DCMS should not spend any more money until "it has developed approaches to secure proper competition and value for money".

In 2011, then Culture Secretary Jeremy Hunt announced 90% of premises in every local authority area of the UK should have access to internet speeds above 24 megabits per second by May 2015, with a minimum of 2Mbps for others.

The process has suffered huge delays and is due to be completed in 2017, nearly two years later than planned.

But, according to Matthew Howett, an advisor at Ovum which examines the commercial impact of technology, the delays were down to the EU's failure to approve the scheme.

He said the "challenges of deploying to the most rural and remote areas of the UK shouldn't be underestimated" and that there were not many providers who could do this.

Gates calls Ctrl+Alt+Del a mistake

26 September 2013 Last updated at 10:50 ET

Bill Gates has described the decision to use Ctrl+Alt+Del as the command needed to log on to a PC as a mistake.

Originally designed to trigger a reboot of a PC, it survives in the Windows 8 operating system as the command to access the task manager toolbar and is still used in older versions to log on.

In an interview, the Microsoft co-founder blamed IBM for the shortcut, saying he had favoured a single button.

The keyboard shortcut was invented by IBM engineer David Bradley.

Originally he had favoured Ctrl+Alt+Esc, but he found it was too easy to bump the left side of the keyboard and reboot the computer accidentally so switched to Ctrl+Alt+Del because it was impossible to press with just one hand.

During IBM's 20th anniversary celebrations, he said that while he may have invented it, Bill Gates made it famous.

His involvement in the invention has made him something of a programming hero though- with fans asking him to autograph keyboards at conferences.

Finger strike

The shortcut, also known as the three-finger salute - came to prominence in the early 1990s as a quick fix for the infamous "blue screen of death" on PCs.

But speaking at a fundraising campaign at Harvard University, Mr Gates said he thought that it had been a mistake.

"We could have had a single button, but the guy who did the IBM keyboard design didn't want to give us our single button."

While some loathe the clunky command, others took to news site Reddit to express their fondness for it.

"I feel a single button would be a mistake," said one.

"There's a conscious commitment and in many cases a sense of satisfying sword play in executing the two-handed finger strike of Ctrl-Alt-Del."

Google reveals new search upgrade

Google search expert Amit Singhal outlines his vision

Google has unveiled an upgrade to the way it interprets users' search requests.

The new algorithm, codenamed Hummingbird, is the first major upgrade for three years.

It has already been in use for about a month, and affects about 90% of Google searches.

At a presentation on Thursday, the search giant was short on specifics but said Hummingbird is especially useful for longer and more complex queries.

Google stressed that a new algorithm is important as users expect more natural and conversational interactions with a search engine - for example, using their voice to speak requests into mobile phones, smart watches and other wearable technology.

Hummingbird is focused more on ranking information based on a more intelligent understanding of search requests, unlike its predecessor, Caffeine, which was targeted at better indexing of websites.

We just changed Google's engines mid-flight - again"

End Quote Amit Singhal Senior VP, Google Search

It is more capable of understanding concepts and the relationships between them rather than simply words, which leads to more fluid interactions. In that sense, it is an extension of Google's "Knowledge Graph" concept introduced last year aimed at making interactions more human.

In one example, shown at the presentation, a Google executive showed off a voice search through her mobile phone, asking for pictures of the Eiffel Tower. After the pictures appeared, she then asked how tall it was. After Google correctly spoke back the correct answer, she then asked "show me pictures of the construction" - at which point a list of images appeared.

Big payoffs?

However, one search expert cautioned that it was too early to determine Hummingbird's impact. "For me this is more of a coming out party, rather than making me think 'wow', said Danny Sullivan, founder of Search Engine Land.

"If you've been watching this space, you'd have already seen how they've integrated it into the [predictive search app] Google Now and conversational search.

"To know that they've put this technology further into their index may have some big payoffs but we'll just have to see how it plays out," Mr Sullivan said.

The news was announced at an intimate press event at the Silicon Valley garage where founders Sergei Brin and Larry Page worked on the launch of the search engine, which is fifteen years old on Friday.

At the event, the search behemoth also announced an updated search app on Apple's iOS, as well as a more visible presence for voice search on its home page.

Electronic Arts cans football game

27 September 2013 Last updated at 06:42 ET

Electronic Arts, the US games maker, says it is cancelling its college football game next year amid legal disputes over players' image rights.

The company said it was "evaluating our plan for the future of the franchise".

Student players have been seeking a share of National Collegiate Athletic Association revenues after their likenesses were used in the game.

In May, a court upheld the right of Ryan Hart, a former college player, to sue.

Mr Hart has sued for damages, saying EA should have sought his permission before using his likeness in three versions of the popular game published between 2004 and 2006.

The appeal court decided EA did not do enough to "sufficiently transform" the virtual version of the player.

Compensation

Samuel Keller, another former college football player, has also sued EA for using his likeness in the game.

"We have been stuck in the middle of a dispute between the NCAA and student athletes who seek compensation for playing college football," wrote Cam Weber, general manager of American football at EA Sports, explaining the company's decision.

Mr Weber said the company was "working to settle the lawsuits with the student athletes", and soon after publishing this statement US newspapers reported that EA had settled, but no details were given.

EA launched its most recent version of the game, NCAA Football 14, in July.

"Our decision does not affect our commitment to NCAA Football 14 and the consumers who love playing the game," Mr Weber said.

Miss Teen USA webcam hacker charged

Miss Teen USA

A 19-year-old student has been charged with hacking Miss Teen USA's webcam.

Jader James Abrahams is charged with trying to blackmail Cassidy Wolf into sending him nude photos.

He surrendered to FBI agents and faces up to two years in prison, said FBI spokeswoman Laura Eimiller.

Last month, Ms Wolf told NBC's Today show that she had received an anonymous email in which the sender claimed to have stolen images from the beauty queen's computer camera.

The sender of the email threatened to make the images public unless she would provide nude pictures of herself, Eimiller said.

Miss Teen USA

Ms Wolf, 19, was crowned Miss Teen USA in August.

Abrahams is accused of using malicious software to remotely operate webcams to get nude photos and videos of at least seven women as they changed clothes.

Some of these women he knew personally and others he found by hacking Facebook pages.

I'll tell you this right now! I do not have a heart. However, I do stick to my deals. Also age doesn't mean a thing to me

Jader James Abrahams

The agent who interviewed him claims that Abrahams admitted to controlling 30 to 40 hacked computers and extorting some women.

Abrahams is studying computer science at university. He is currently on bail and only allowed to use his computer, which is being monitored, for coursework.

After getting the nude pictures he would send emails threatening to post them on their hacked social media accounts unless they either sent him more nude photos, a nude video, or logged onto Skype and followed his orders for five minutes.

Court records say that one teenager in Ireland wrote back: "Please remember I'm 17. Have a heart."

They claim Abrahams responded: "I'll tell you this right now! I do not have a heart. However, I do stick to my deals. Also age doesn't mean a thing to me!"

Blackberry loss after sales slump

27 September 2013 Last updated at 09:48 ET

Blackberry has reported a second quarter net loss of $965m (£600m) following a slump in sales.

The company warned investors last week that it would report a loss of up to a billion dollars, due to poor sales of its new smartphones.

It also announced 4,500 job cuts in a bid to stem those losses.

Earlier this week Blackberry agreed to be bought by a consortium led by Fairfax Financial, its biggest shareholder, for $4.7bn (£3bn).

Blackberry said it would continue to explore other options while negotiations with Fairfax continued.

The company's financial problems came to a head this year following disappointing sales of its new Z10 smartphone.

Sales were so poor that Blackberry had to write off $934m in the second quarter to account for the weakness.

Disappointment

Released in January - after many delays - the phone has failed to enthuse consumers.

The firm reported total sales of $1.6bn compared with $3.1bn in the same quarter of 2012, a near 50% fall.

"We are very disappointed with our operational and financial results this quarter and have announced a series of major changes to address the competitive hardware environment and our cost structure," said Thorsten Heins, Blackberry's chief executive.

In the second quarter, Blackberry said it sold 3.7 million Blackberry smartphones. That compares with 7.4 million shipments in the same period of 2012.

To put that into perspective, Apple sold nine million of its new iPhone 5S and 5C models on the opening weekend of sales.

Decay

In a research note, Colin Gillis from the brokers BGC, said the results were "startling weak".

He said the company's plan to focus on corporate customer, might fail.

"While we applaud the decision to focus on retooling the company into a niche enterprise focused business, it seems years too late.

"Just as the consumer business has crumbled, the enterprise business is also in decay in our opinion.

"Given the negative news flow from the company, enterprise customers are likely to shy away from committing to a struggling platform," Mr Gillis said.

Microsoft boss cries at send-off

27 September 2013 Last updated at 09:54 ET

Departing Microsoft boss Steve Ballmer has hosted his last company meeting - bidding a tearful farewell to employees he has worked with for 33 years.

The 57-year-old danced to Michael Jackson's Wanna Be Startin' Somethin', and declared that the company would "change the world again".

More than 13,000 Microsoft employees had queued to be a part of the annual company-wide event.

The firm has not yet announced a replacement chief executive.

Mr Ballmer will retire within the next year and will leave the company in a strategically precarious position as it looks to claw back lost ground in the mobile sector.

While at the helm, he became known for his vigorous and enthusiastic presentations in which he would routinely declare his love for Microsoft and its products.

Dirty Dancing

Microsoft staff took to social media to share details of Mr Ballmer's last appearance as boss at the event described as being more like a "rock concert".

It was held at the 17,000-capacity Key Arena in Seattle, a venue usually used for basketball and ice hockey.

Steve Ballmer at Microsoft corporate event in 2000: "I love this company"

Service engineer Bob Ulrich posted a picture on Twitter of the snaking queue outside the building.

He added: "Must be the year to go to the @Microsoft company meeting. Insane line."

Charles Naut, a project manager at the company, posted an image of the "very moving" speech on Instagram - it showed Mr Ballmer ending his talk by saying, "I've had the time of my life!" as the famous Dirty Dancing song was played out in the arena.

Too slow

The Verge reported that Mr Ballmer had tears streaming down his face as he made his last remarks, telling employees: "We have unbelievable potential in front of us, we have an unbelievable destiny. Only our company and a handful of others are poised to write the future.

"We're going to think big, we're going to bet big."

He took aim at some of the company's rivals, calling Apple "fashionable" and Amazon "cheap". He said Google was focused on "knowing more", while Microsoft was about "doing more".

But it is those rivals that piled the pressure on Mr Ballmer to depart. In one recent meeting with Wall Street investors and analysts, he admitted the company had been too slow expanding into the smartphone market.

"I regret that there was a period in the early 2000s when we were so focused on what we had to do around Windows that we weren't able to redeploy talent to the new device called the phone," Mr Ballmer said.

"That is the thing I regret the most. It would have been better for Windows and our success in other foreign factors."

Valve reveals haptic game controller

27 September 2013 Last updated at 14:32 ET By Dave Lee Technology reporter, BBC News

Games developer and publisher Valve has shown off its Steam Controller, the final part of its strategy to bring its PC-based platform to the living room.

The controller offers two trackpads which provide "haptic" feedback capable of delivering various physical sensations to the player.

Valve said it offers a better way to play games that have traditionally been controlled with a keyboard and mouse.

Gamers have been invited test the device before it goes on sale in 2014.

"Traditional gamepads force us to accept compromises," the company said via its announcement page.

"We've made it a goal to improve upon the resolution and fidelity of input that's possible with those devices.

Continue reading the main story

As innovative and successful a company as Valve certainly is, they're taking some risks here.

Not least their belief that the market they're aiming for is so large. PC games, those distinct to the platform, tend to be focused on more intimate interaction, with the vast complexity of a mouse and keyboard for controls.

It's not a medium that immediately lends itself to a handheld controller from the other side of a room.

It's also worth noting that their idea is not especially novel. Media boxes, and even wheezing PC towers, already sit by a lot of people's televisions, streaming appropriate games from machines in another room, or capable of gaming themselves.

A decent portion of that perceived audience who wants to play PC from afar has likely botched something for themselves. I know I have.

For this to work, Valve is going to have to pitch some really superb tech, running in a small, super-quiet machine, at a very competitive price.

Those are a lot of factors to get right, if they want to seriously compete with the behemoths of sitting room gaming.

"The Steam controller offers a new and, we believe, vastly superior control scheme, all while enabling you to play from the comfort of your sofa."

Research and testing

The controller is the third announcement the company has made this week. On Monday, it outlined plans to create an entire Linux-based operating system for running games, and followed up on Wednesday with details of the Steam Machine, essentially a new type of games console.

The widely-anticipated controller completes what Valve will hope is a strategy that can shift gamers that use traditional PCs - which is seen as a market headed for decline - and coax them into the living room.

However, the biggest challenge the company faces in doing so is in convincing gamers who have spent years playing titles, particularly first-person shooters, by using a combination of keyboard and mouse that a handheld controller can offer a more enjoyable solution.

The company said it had spent a year researching and testing different control methods. It said the haptic feedback offered new possibilities for creating immersive gaming.

"This haptic capability provides a vital channel of information to the player - delivering in-game information about speed, boundaries, thresholds, textures, action confirmations, or any other events about which game designers want players to be aware."

The company is to send out 300 early versions of the controller to people who sign up for beta testing.

Giant owl eyes

Rob Crossley, associate editor of Computer and Video Games, has been following Valve's announcements throughout this week. He has described the latest move as "fearless".

"Controller design standards haven't changed since the first PlayStation... the D-pad, the two sticks... that's evolved only slightly over the last 20 years.

"Sure, it looks a little funny - those two giant owl eyes - but I think that this could lead to a change in the way we look at controllers."

Valve is banking on the trackpads providing the same kind of precision offered by a mouse, Mr Crossley added.

"I think they believe this is their best attempt at trying to map the precision of the mouse onto a gamepad.

"If it does pay off, if they do manage to emulate the mouse on a controller, that opens up whole new genres."

Some had speculated - somewhat hopefully - that Valve would make a surprise announcement about the next instalment in its Half-Life series.

However, there was no mention of the game in any of Valve's announcements - but many now speculate that Half-Life 3 could be a launch title for the new Steam system and controller.

"The natural thinking is surely they will show off Half-Life 3 when SteamOS is launched," said Mr Crossley.

"A lot of people are also saying that it would be exclusive to the Steam Machine - but that would be a very un-Valve-like thing to do. They've always been very open."
