More than 50 programmers, scientists, students, hobbyists and fans of the A.L.I.C.E. chat robot gathered in Guildford, U.K. on Friday to celebrate the tenth birthday of the award winning A.I. On hand was the founder the Loebner Prize, an annual Turing Test, designed to pick out the world’s most human computer according to an experiment laid out by the famous British mathematician Alan Turing more then 50 years ago. Along with A.L.I.C.E.’s chief programmer Dr. Richard S. Wallace, two other Loebner prize winners, Robby Garner and this year’s winner, Rollo Carpenter, also gave presentations, as did other finalists.
The University of Surrey venue was chosen, according to Dr. Wallace, not only because it was outside the U.S. (A.L.I.C.E.’s birthday fell on the Thanksgiving Day weekend holiday there, so he expected few people would attend a conference in America), but also because of its recently erected statue of Alan Turing, who posed the famous A. I. experiment which inspired much of the work on bots like A.L.I.C.E. University of Surrey Digital World Research Centre organizers Lynn and David Hamill were pleased to host the event because it encourages multi-disciplinary interaction, and because of the Centre’s interest in interaction between humans and computers.File:ALICE Birthday Cake.jpg
Dr. Wallace gave a keynote address outlining the history of A.L.I.C.E. and AIML. Many people commented on the fact the he seemed to have moved around a lot in the last ten years, having lived in New York, Pennsylvania, San Francisco, Maine, Amsterdam and Philadelphia, while working on the Alicebot project. The A.L.I.C.E. and AIML software is popular among chat robot enthusiats primarily because of its distribution under the GNU free software license. One of Dr. Wallace’s PowerPoint slides asked the question, “How do you make money from free software?” His answer: memberships, subscriptions, books, directories, syndicated ads, consulting, teaching, and something called the Superbot.
Rollo Carpenter gave a fascinating presentation on his learning bot Jabberwacky, reading from several sample conversations wherein the bot seemed amazingly humanlike. Unlike the free A.L.I.C.E. software, Carpenter uses a proprietary learning approach so that the bot actually mimics the personality of each individual chatter. The more people who chat with Jabberwacky, the better it becomes at this kind of mimicry.
In another interesting presentation, Dr. Hamill related present-day research on chat robots to earlier work on dialog analysis in telephone conversations. Phone calls have many similarities to the one-on-one chats that bots encounter on the web and in IM. Dr. Hamill also related our social expectations of bots to social class structure and how servants were expected to behave in Victorian England. He cited the famous Microsoft paperclip as the most egregius example of a bot that violated all the rules of a good servant’s behavior.
Bots have advanced a long way since philanthropist Hugh Loebner launched his controversial contest 15 years ago. His Turing Test contest, which offers an award of $100,000 for the first program to pass an “audio-visual” version of the game, also awards a bronze medal and $2000 every year for the “most human computer” according to a panel of judges. Huma Shah of the University of Westminster presented examples of bots used by large corporations to help sell furniture, provide the latest information about automotive products, and help customers open bank accounts. Several companies in the U.S. and Europe offer customized bot personalities for corporate web sites.
Even though Turing’s Test remains controversial, this group of enthusiastic developers seems determined to carry on the tradition and try to develop more and more human like chat bots.Hugh Loebner is dedicated to carry on his contest for the rest of his life, in spite of his critics. He hopes that a large enough constituency of winners will exist to keep the competition going well beyond his own lifetime. Dr. Wallace says, “Nobody has gotten rich from chat robots yet, but that doesn’t stop people from trying. There is such a thing as ‘bot fever’. For some people who meet a bot for the first time, it can pass the Turing Test for them, and they get very excited.”

President Bush defends NSA domestic intercepts

In a radio speech from the White House on 17 December 2005, President Bush acknowledged that in the weeks following 9/11 he had “authorized the National Security Agency [NSA], consistent with U.S. law and the Constitution, to intercept international communications of people with known links to al Qaeda and related terrorist organizations.”
President Bush said that the government establishes a clear link to terrorist networks before intercepting these communications, adding that the purpose of the program is to “detect and prevent terrorist attacks against the United States and our allies.”
Stating that terrorists inside the United States were communicating with terrorists abroad before the 9/11 attacks, President Bush said that the authorization he gave the NSA “helped address that problem in a way that is fully consistent with my constitutional responsibilities and authorities.”
Secretary of State Condoleezza Rice said that established procedures requiring court approval were simply not quick and flexible enough to respond to the urgency of the terrorist threat, and to allow the administration to eavesdrop on highly mobile targets in order to disrupt potential plots.
Before Bush’s secret order, such wiretaps were obtained through the Foreign Intelligence Surveillance Act (FISA) of 1978. It prescribes procedures for requesting judicial authorization for electronic surveillance and physical search of persons engaged in espionage or international terrorism against the United States on behalf of a foreign power. FISA also allows the Attorney General to grant permission for emergency wiretaps without a warrant, with retroactive application being made within 72 hours. Historically, the vast majority of applications are accepted without modifications by FISA. For example in the 2004 report of FISA to Congress it is noted that the number of approved warrants with substantive modifications was 94 out of a total of 1758 while 5 applications were rejected.
House Intelligence Committee Chairman Peter Hoekstra defended Bush’s authorization of the surveillance program and to bypass the FISA. Chairwoman of the Homeland Security and Governmental Affairs Committee Senator Susan Collins announced a call on the NSA for a “full briefing” about the program, and said that the program’s authority needs to be clarified. House Minority Leader Nancy Pelosi said Bush’s radio address raised “serious questions as to what the activities were and whether the activities were lawful.”
The President noted that the NSA activities are reviewed “approximately every 45 days.” He added: “During each assessment, previous activities under the authorization are reviewed. The review includes approval by our nation’s top legal officials, including the attorney general and the counsel to the president.” All people involved in the periodic review are members of the executive branch.
Bush also said that NSA’s activities under this authorization are thoroughly reviewed by the Justice Department and NSA’s top legal officials, including NSA’s general counsel and inspector general, adding that “leaders in Congress have been briefed more than a dozen times on this authority and the activities conducted under it.” Members of Congress from both parties are now calling for congressional hearings to learn more.
The president concluded by saying that “this authorization is a vital tool in our war against the terrorists. It is critical to saving American lives. The American people expect me to do everything in my power under our laws and Constitution to protect them and their civil liberties.”
