[EX Q]: (CNN) -- Facebook will soon be using your Web browsing to help decide which advertisements you see. A new Facebook system will use your activity on other websites to send you what Facebook thinks are ads about your current interests. Advertisers will, in effect, be bidding to get their ads in front of you. Here's an example: Say a Facebook user visits a travel website and clicks on a page about a vacation package to Las Vegas. If an advertiser has bid on that kind of search, that user could then see ads for discounted trips to Vegas the next time they visit Facebook. "By bidding on a specific impression rather than a larger group, advertisers are able to show people more relevant ads while also running more efficient and effective campaigns," a Facebook spokeswoman said in a written statement. The site announced the new system, called Facebook Exchange, to marketers last week. It's expected to begin rolling out in the next couple of weeks. Real-time bidding is already widely used across the Internet. In a blog post, Mike Stiles of Atlanta-based social marketing company Vitrue compared the feature to Google's Ad Words, which pushes an advertiser's ad in front of users when they search for a keyword that advertiser has chosen. "The underlying principle is that users want relevant ads, advertisers don't want to waste money on misguided ads, and Google wants both users and advertisers to be real happy so they'll come back again and again," he wrote. Currently, Facebook ads are targeted based on users' profiles and the companies or other pages they "like." Stiles writes that model will still be available for advertisers, but the new one should be more specific. Facebook noted that users will be able to opt out of Exchange by going to the site's About Ads page, by clicking on an "X" that appears on the ads themselves or by blocking cookies on their Web browser. The company statement said Facebook won't share any user data with the advertisers and that no advertising controls that users currently have will go away. How do you feel about Facebook targeting ads? Jim Anderson, Vitrue's chief operating officer, said the new system probably won't appear dramatically different to the typical Facebook user. "It's not going to be discernible to most consumers," he said. "Most people won't notice any difference or, to the degree they can discern a difference, it will be 'Wow ... this is more relevant to me.'' " And while the "real time" nature of the new system will enhance relevance, it won't be perfect, according to Anderson. "It's possible you might not be served an ad until after you took that trip to Vegas," he said, referring to the previous example. "But without this kind of targeting, you might be served an ad for a trip to Miami, which you weren't considering anyway." As Web giants like Facebook and Google get better at harvesting user activity, using Web searches for advertising is becoming increasingly popular. According to research firm International Data Corporation, more than $5 billion in online advertising is expected to go to real-time bidding ads in the United States in 2015. That's 27% of what's predicted to be spent, up from less than 10% last year. Facebook, of course, is increasingly under pressure to demonstrate a sustainable advertising model since its stock went public last month. Anderson predicts the site will continue to diversify how its ads work in the coming months. It's sometimes a tricky prospect. It was just revealed that Facebook settled a lawsuit last month by the state of California over its "Sponsored Stories" feature. According to reports, Facebook paid $10 million to charity after five users claimed the site broke California law when it used their posts in the feature without paying them.

[EX Q]: PARIS, France (CNN) -- Three French journalists charged in an alleged plot to kidnap African children for adoption in Europe arrived in Paris on Sunday, hours after French President Nicolas Sarkozy held emergency talks in Chad. But 14 other people remained in custody in the African nation, some facing serious charges that could send them to jail for up to 20 years. The journalists were among seven Europeans a Chadian judge released Sunday, including a Spanish flight crew, whom Sarkozy dropped off in a brief stop in Madrid on his way back from Chad. All were arrested last week after workers from Zoe's Ark -- a French-based charity group -- were accused of trying to fly 103 children out of Chad in a kidnapping and adoption operation.  Watch a report on how the events unfolded » . Some of the children may never return to their families because it is too difficult to determine their backgrounds, Red Cross spokeswoman Inah Kaloga told CNN on Friday. Those who remain under arrest in Chad are six members of the French charity, four Chadians and four remaining members of the flight crew. Some face kidnapping and fraud charges. Zoe's Ark leader Eric Breteau testified Saturday to a court in the Chadian capital that the three journalists and the flight crew of seven Spaniards and a Belgian were not involved in the alleged plot, court witnesses told CNN. At least some of the flight crew are scheduled to testify before a judge on Monday. The three journalists initially had been charged with complicity in the alleged kidnapping attempt. It's not clear if the charges against them have been dropped.  Watch the freed Europeans leave Chad » . In a joint news conference with Spanish Prime Minister Jose Luis Rodriguez Zapatero on Sunday at Madrid's Torrejon Air Force Base, Sarkozy expressed satisfaction that some of those detained had been released. At the same time, however, he told reporters, "We should respect the sovereignty of Chad." Zapatero thanked Sarkozy for dropping the four Spanish flight crew members off in their home country, and thanked Chadian President Idriss Deby for allowing them to return. After his emergency talks in Chad, Sarkozy stressed the scandal would not affect the strong relations between the two countries or affect the planned deployment of a European force to protect refugees from Sudan's Darfur region who have fled to Chad and the neighboring Central African Republic. Sarkozy also said he hoped the six remaining French nationals -- all from Zoe's Ark -- would face trial in France. The charity says that the children were orphans from the Darfur region -- where the United Nations estimates 200,000 people have been killed in four years of conflict -- and that the group was taking them to host families in France. But after preliminary interviews with the children, aid agencies said Thursday it appeared most of them probably are not orphans and not from Sudan, but instead come from villages on the Chadian side of the border with Sudan. The children are staying in an Abeche orphanage while aid agencies and government officials try to find out where they came from -- a challenge hindered by the number of children, their youth, and the volatile situation in the region. A father of three of the children allegedly kidnapped told a French newspaper he put his children into the charity's care after he was told they would be educated at a school under construction in a nearby town. The Chadian man, who gave his name as Arbab, told Le Parisien on Sunday that workers from Zoe's Ark had visited his village three times. "They never said they would take away our children," he told the newspaper. E-mail to a friend . CNN's Nic Robertson and Al Goodman contributed to this report.

[EX Q]: (CNN) -- She's got nerves of steel, golf talent beyond her tender years, and a precocious flair for eye-catching fashion: 11-year-old Lucy Li, the youngest qualifier in U.S. Women's Open history, looked entirely at home as she teed-off at Pinehurst No. 2. Despite a three bad holes in North Carolina, which meant she finished her round with an eight-over-par 78, Li impressed onlookers with a composed round that saw her bounce back quickly from disappointing shots. She left the course smiling, having followed up two double-bogeys and a triple-bogey with assured play -- including birdies at the first and fifth. "It was great," Li told reporters Thursday. "What I was so happy about in my round, (was that) after I got doubles and triples, I was able to get it back. And I got a lot of pars after that." Heading into the tournament, Li said her only ambition was to "have fun and play the best I can." But the California native can also count growing experience in her time at Pinehurst, not least how to deal with the perilous course -- which hosted the men's U.S. Open last week. "It's tough," said Li. "You miss the ball by three feet and it could be like a two- or three-shot difference. "You could hit it three feet more right and you'd be putting this far away for birdie. Or you could be in the bunker and struggling for a bogey." Tour pros had raised doubts about whether the child amateur -- still wearing braces and standing on a box to address the media after her opening round -- should be subjected to the pressure and expectation of such a big professional event. "When I found out she qualified, I said, 'Well, where does she go from here? You qualify for an Open at 11, what do you do next?' " asked world No. 1 Stacy Lewis on Wednesday. The 29-year-old added: "If it was my kid, I wouldn't let her play in the U.S. Open qualifier at 11, but that's just me." Pressure seemed to be the least of Li's worries as she chatted with the older members of her playing group and feasted on an ice cream during the post-round press conference. "She is so mature for her age," said 23-year-old Jessica Wallace, who played with Li and Catherine O'Donnell -- the latter also shot 78. "There were times when I felt more immature than she is. Catherine and I had fun talking to her. She's so mature, it's like talking to another 23-year-old." Li became officially the youngest player to qualify after securing her place at an event at Half Moon Bay Golf Club near her home in California. She beats fellow American Lexi Thompson, who qualified for the 2007 Open aged 12, to become the youngest qualifier. But Li is not the youngest to compete at the tournament -- Beverley Klass competed in 1967, without having to qualify, aged just 10. While Canadian Wallace carded 74 to be on course to make the halfway cut, seven shots behind first-round leader Lewis, Li and O'Donnell were outside the projected top-60 ahead of their second rounds Friday. And there wasn't a fairytale end for Li -- she missed the weekend rounds after carding another 78 on Friday, laced with more highs and lows as she tied for 120th in the 154-player field. "I'm really happy with how I bounced back from the big numbers," said Li, who again had to stand on a box to reach the microphone at her press conference Friday. "Just be patient and not care about what happened, just go to the next shot and hit it like nothing, like it's the first shot." Her caddy Bryan Bush added: "She proved that she deserved to be here. Her play spoke for itself. "It was never about score," he said. "She was here for the experience and the opportunity to play with the best players in the world. She proved that she can." The weekend attention switched from one child prodigy to a former one, as Michelle Wie claimed a three-shot lead from Thompson. The 24-year-old Wie also came to prominence at a young age but is still seeking her first major title. She birdied the last two holes to move clear of 19-year-old Thompson, who at 16 was the youngest winner of an LPGA event until that record was taken by Lydia Ko in 2012. New Zealand's Ko, now 17, fired 71 to move up the leaderboard and make the cut, being tied for 29th. World No. 1 Stacy Lewis dropped from the opening-round lead to a tie for third after a 73 which left the American four shots behind compatriot Wie.
