Software That Listens for Lies

Julia Hirschberg, a professor of computer science at Columbia University, may spell trouble for a lot of liars. That’s because Dr. Hirschberg is teaching computers how to spot deception — programming them to parse people’s speech for patterns that gauge whether they are being honest.

For this sort of lie detection, there’s no need to strap anyone into a machine. The person’s speech provides all the cues — loudness, changes in pitch, pauses between words, ums and ahs, nervous laughs and dozens of other tiny signs that can suggest a lie. Dr. Hirschberg is not the only researcher using algorithms to trawl our utterances for evidence of our inner lives. A small band of linguists, engineers and computer scientists, among others, are busy training computers to recognize hallmarks of what they call emotional speech — talk that reflects deception, anger, friendliness and even flirtation. Programs that succeed at spotting these submerged emotions may someday have many practical uses: software that suggests when chief executives at public conferences may be straying from the truth; programs at call centers that alert operators to irate customers on the line; or software at computerized matchmaking services that adds descriptives like “friendly” to usual ones like “single” and “female.” The technology is becoming more accurate as labs share new building blocks, said Dan Jurafsky, a professor at Stanford whose research focuses on the understanding of language by both machines and humans. Recently, Dr. Jurafsky has been studying the language that people use in four-minute speed-dating sessions, analyzing it for qualities like friendliness and flirtatiousness. He is a winner of a MacArthur Foundation fellowship commonly called a “genius” award, and a co-author of the textbook “Speech and Language Processing.”

Syrian government reportedly bans use of Apple iPhone

The Syrian government has reportedly banned the use of the Apple iPhone in an effort to prevent activists from documenting the ongoing uprising in that country and government violence against protesters. Activists in Beirut were notified of the iPhone ban in a letter from the Syrian Finance Ministry that reads "the authorities warn anyone against using the iPhone in Syria."

Seeking to copy -- legally-- from Blu-ray discs and online media

One of the criticisms of the digital locks used by broadcasters and Hollywood studios is that, in trying to squelch piracy, they can interfere with fair uses of copyrighted material by other artists. And under federal law, it's illegal to circumvent those locks.

Chicago-based Kartemquin Films and other documentary filmmakers won a temporary exemption from that law a year and a half ago, with the help of students at the USC Intellectual Property and Technology Law Clinic and lawyers from Donaldson & Callif of Beverly Hills. Now the clinic and the firm are seeking to extend the exemption to all filmmakers and authors of multimedia e-books. The 1998 Digital Millennium Copyright Act made it illegal to circumvent "technical protection measures" on DVDs and other digital media. That created a dilemma for filmmakers who wanted to use a snippet from an earlier movie on DVD: Even if the use wasn't infringing, they could still be sued for going around the locks. So even though circumvention tools are widely available online (despite the fact that they're illegal to make or distribute), filmmakers used them at their peril. That's why documentarians sought an exemption from the Copyright Office in 2009. Recognizing the potentially chilling effects of the anti-circumvention provision, lawmakers had included in the 1998 law a requirement that the office consider granting relief every three years to those whose non-infringing uses were adversely affected. The exemption documentarians won in July 2010 applies only to DVDs, and it expires next year. In seeking a new exemption, the filmmakers are focused on two problems, said Jack Lerner, a law professor at USC who directs the Intellectual Property and Technology Law Clinic.

Broadcasters to Appeal Media Ownership Decision to Supreme Court

The National Association of Broadcasters plans on Dec. 5 to ask the Supreme Court to overturn the Third Circuit's decision that leaves most of the Federal Communications Commission's media ownership limits in place.

Apparently, News Corp. will also challenge the rules. There are expected to be a number of petitions filed. The Third Circuit Court of Appeals in July upheld the FCC's 2008 decision not to loosen the TV duopoly, radio ownership or TV-radio crossownership rules and vacated and remanded its loosening of the broadcast/newspaper crossownership rule for failure to meet notice and comment requirements.

Coalition Asks FCC to Focus on Diversity in Quadrennial Ownership Rule Review

The Leadership Conference on Civil and Human Rights has written the Federal Communications Commission to ask that it focus on diversity in its quadrennial media ownership rules review.

In its letter, the conference (a coalition of 200-plus diversity groups) said that the FCC currently has "no meaningful policies to address racial and gender inequities in media ownership" and has "ignored the impact of its media ownership rules on those inequities." It pointed to the Third Circuit remand the court's admonition that the FCC was "punting yet again" on diversity. "As media consolidation grows, people of color and women become less significant players in the media ecosystem. The Commission must acknowledge that fact and take action to remedy it," the coalition said. Groups also signing on to the letter included the Communications Workers of America, National Urban League, NAACP, NOW and the UCC Office of Communication.

In addition, on Dec 1, more than 50 groups representing a wide range of women’s, media and social justice organizations, including Free Press, sent a letter to the FCC urging the agency to make diversity issues a priority in its upcoming review.

Senate Commerce Slates Votes on FCC Nominees

The Senate Commerce Committee has scheduled a vote Dec. 8 on the nominations of Jessica Rosenworcel and Ajit Pai to be commissioners on the Federal Communications Commission. They are expected to sail through that next step in the process.

Uncovering the Truth about Retransmission Value

[Commentary] SNL Kagan has supplied some ammo for stations to take into their next retransmission negotiations with cable and satellite operators. It's a report showing growth of the cash flow margins of cable networks, and it's the retrans equivalent of the Predator drone.

What it shows is just how fat cable networks have become. According to its research, more than 30 networks have margins of 50% or more topped by Nickelodeon, with a 64.6% margin and the Food Network at 60.5%. Next in line: NBCU's CNBC World and CNBC at 59.9% each; Viacom’s VH1 Classic at 59.3%; Discovery Communications’ TLC at 58.7%; The Disney Channel at 57.7%; Scripps’ HGTV at 57.1%; the Discovery Channel at 57%; and AMC Network's AMC at 55.4%. The average margin of all cable networks in 2010 was 41%, which SNL researchers found "amazing, given the fact that there are a number of networks with negative cash flow margins and emerging networks with low margins in the mix. "In addition, sports networks typically have lower cash flow margins than general entertainment and other genres," the reports says. "ESPN, for instance, which makes up almost 15% of industry revenue, has a cash flow margin of just 25.3%." And the gilded gated community of cable's super rich is expanding. By 2015, the number of 50%-margin-plus networks will nearly double to 58, the report says. And there will be another 61 with margins between 40% and 50% and 32 in the 30%-40% range. So, when your local cable operator gags on your asking $1 per sub per month (which is the least you should be getting) and says he can't afford anything close to that, show him the SNL Kagan report and point out that it isn't your neighborhood broadcasters who are getting rich off of his subscribers, but those remote cable networks that, by the way, only have a fraction of the audience that you have. The reason that the cable networks can post such margins despite their paltry ratings is because cable and satellite operators mindlessly pay them programming fees that have no relation to the audiences they are delivering.

In Europe, Tablets Replace TV Viewing But Smartphones Complement It

Tablet use cannibalizes TV consumption and drives m-commerce, according to a new survey into the mobile media habits of 5,000 Europeans in the U.K., France, Spain and Poland. In the U.K., 35% of tablet users regularly watch on-demand content, 40% view streamed content, and 39% are watching TV on their tablet instead of on a television set. Smartphones, by contrast, tend to complement TV consumption rather than replacing it. That's particularly true in France, where 19% of users say they watch more TV on a TV set as a result of their mobile usage. Phones also have a more positive impact on other digital media use, driving 20% of U.K. customers to browse more on PCs, and 15% to read more newspapers online. Of tablet users, 21% read their newspapers online. The research, carried out independently by TNS and commissioned by Orange, showed distinct differences in behavior between mobile and tablet usage. Smartphones are used to "kill time" when there is no access to other screens, while tablets are used to "save time" because they are perceived as efficient.

How Social Media Is Changing Law Enforcement

Public safety is a bit more sophisticated, and methods of communication much faster. Law enforcement tools have evolved from wanted posters to police radio, patrol cars and social networks, such as Twitter, Facebook and YouTube. Community policing today has also expanded through social networking to locate missing children, alert neighbors of suspicious activity and even inform the public about crimes committed in their neighborhoods. But social networking is a tool that cuts both ways. Flash mobs organized online in Philadelphia swarmed stores to shoplift and attack pedestrians; pedophiles use social networking platforms to share photos and video; and terrorists recruit members and plan attacks via these tools. Even the courts have been affected. Jurors have disregarded instructions and have conducted online research, shared their opinions on Twitter from the jury box, and even posted biased comments on their Facebook pages.

NPR CEO Gary Knell Talks Public Funding, Diversity On First Day

Gary Knell has his work cut out for him as he takes the helm as National Public Radio's new CEO.

He sat down with Neal Conan on "Talk of the Nation" to answer some critical questions about the network, specifically its reliance on public funding, the possibility of privatizing NPR, and plans to improve diversity. Knell defended the necessity of public funding, calling it "an important leg" of the network's finances. He acknowledged that the network could no longer take public funding for granted, and promised that it would "work like heck" to make a better case for it in Congress. He also shot down the idea of NPR becoming for-profit -- which some have championed as a way of getting around public funding. He pointed to non-profit enterprises like Sesame Street and the BBC that have tapped into unique funding opportunities, and said that NPR would try to do the same. He hinted at future plans to diversify NPR's audience, which has long been a point of criticism for the network. He said, "We shouldn't rule out second-language programming - Spanish among them, Mandarin and other programming." He emphasized improving digital platforms to reach out to younger listeners as well.
