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.”

Six people, including two children, were found dead in a Memphis, Tennessee home in the United States on Monday. Three wounded children were also found at the scene, a 7-year-old boy, a 10-month-old girl and a 4-year-old whose gender was not reported, were sent to Le Bonheur Children’s Medical Center. Two were last reported in very critical condition, while the other was in serious condition.

All of the victims had either gunshot or stab wounds, or both, and were all found in the same room. Its unclear as to the day it happened, but a neighboor from across the street said he heard gunshots being fired at around 8:30 p.m. on Sunday night.

The killer is still at large. “This is a stain on our community, and we really need the community’s help,” said Lt. Joe Scott of the Memphis Police Department at a press conference today.

“I don’t know the answer,” Mayor Willie Herenton told local television. “I don’t think anybody knows the answer. I don’t think more police officers, more jails, more people marching in the streets, praying — I don’t think all of those things are the answers.”

Top broker and Wall Street adviser Bernard L. Madoff, aged 70, was arrested and charged by the FBI on Thursday with a single count of securities fraud, also known as stock fraud and investment fraud. He allegedly told senior employees of his firm on Wednesday that his $50 billion business “is all just one big lie” and that it was “basically, a giant Ponzi scheme (since at least 2005).” Mr. Madoff faces up to 20 years imprisonment and a fine of up to $5 million. FBI agent Theodore Cacioppi said Mr. Madoff’s investment advisory business had “deceived investors by operating a securities business in which he traded and lost investor money, and then paid certain investors purported returns on investment with the principal received from other, different investors, which resulted in investors’ losses of approximately $50 billion dollars.”

The former chairman of the Nasdaq Stock Market is also the founder and primary owner of Bernard L. Madoff Investment Securities LLC, the closely-held market-making firm he launched in 1960. The firm is one of the top market maker firms on Wall Street. He founded his family firm with an initial investment of $5,000, after attending Hofstra University Law School. He saved the money earned from a job lifeguarding at Rockaway Beach in Queens and a part time job installing underground sprinkler systems.

A force in Wall Street trading for nearly 50 years, he has been active in the National Association of Securities Dealers (NASD), a self-regulatory organization for the U.S. securities industry. His firm was one of the five most active firms in the development of the NASDAQ, having been known for “paying for order flow,” in other word paying a broker to execute a customer’s order through Madoff. He argued that the payment to the broker did not alter the price that the customer received. He ran the investment advisory as a secretive business, however.

Dan Horwitz, counsel of Mr. Madoff, in an interview, said that “he is a longstanding leader in the financial-services industry with an unblemished record; he is a person of integrity; he intends to fight to get through this unfortunate event.” Mr. Madoff was released on his own recognizance on the same day of his arrest, after his 2 sons turned him in, and posting $10 million bail secured by his Manhattan apartment. Without entering any plea, the Court set the preliminary hearing for January 12.

Madoff’s hedge fund scheme may rank among the biggest fraud in history. When former energy trading giant Enron filed for bankruptcy in 2001, one of the largest at the time, it had $63.4 billion in assets. The scheme would dwarf past Ponzis, and it would further be nearly five times the telecommunication company WorldCom fraud and bankruptcy proceedings in 2002.

The Securities and Exchange Commission filed a separate civil suit on Thursday against Bernard L. Madoff Investment Securities and its eponymous founder Mr. Madoff. It was docketed as “U.S. v. Madoff,” 08-MAG-02735, by the U.S. District Court for the Southern District of New York (Manhattan). SEC, New York associate director of enforcement, Andrew M. Calamari, asked the judge to issue seizure orders on the firm and its assets, and appoint a receiver. The SEC pleads, among others, that “it was an ongoing $50 billion swindle; our complaint alleges a stunning fraud that appears to be of epic proportions.” It further accused the defendant of “paying returns to certain investors out of the principal received from other, different investors” for years. Madoff’s hedge fund business had previously claimed to have served between 11 and 25 clients and had $17.1 billion in assets under management. But virtually all of the assets were missing.

United States District Court for the Southern District of New York Louis L. Stanton on Thursday appointed Lee Richards, a Manhattan lawyer, as the firm’s receiver. A hearing is set for Friday, for a ruling on the SEC’s petition to grant plenary powers to the receiver over the entire firm, and an absolute asset sequestration.

Doug Kass, president of hedge fund Seabreeze Partners Management said that “this is a major blow to confidence that is already shattered — anyone on the fence will probably try to take their money out.”

On Tuesday, Mayor Michael R. Bloomberg announced a weather emergency in New York City, New York. The announcement was issued as a preemptive measure in preparation for an expected 6-12 inches of snow Wednesday, although the Metropolitan Transportation Authority claims to be ready for 14 inches.

Bloomberg explained the meaning of the preemptive announcement by stating: “We recognize that we did not do the job that New Yorkers rightly expect of us in the last storm. We intend to make sure that does not happen again.” Despite declaring an emergency, the mayor said the city would not make the decision to close public schools until 5 AM.

The city is looking for people to shovel snow off sidewalks and intersections. The New York City Housing Authority announced on their Twitter page, “Turn a snow day into a payday. The city is looking for snow removal help. Apply now.” The linked page offered $12 an hour to shovel snow for the city.

Bank of America has announced that it is planning to cut anywhere between 30,000 and 35,000 jobs over the next three years. This comes after the completion of its takeover of the company Merril Lynch.

The job reductions could affect around 11% of the combined workforce of both companies, which amounts to about 308,000 people. The cuts are aimed at saving US$7 billion of annual costs.

Meles Zenawi, the Prime Minister of Ethiopia, has told the parliament that African Union (AU) peacekeepers stationed in the east African country of Somalia want to leave the country by the end of the year.

They have requested that Ethiopian troops that are planning to leave the country at the end of the year to help them withdraw from Somalia’s capital of Mogadishu. There are some 3,200 troops from Uganda and Burundi covering sites in that city.

The withdrawal of the armed forces, however, could leave the area vulnerable to an insugent assault.

The aeroplane manufacturer Boeing has announced that there will be another delay in the launch of its 787 “Dreamliner” aircraft. The postponement has been blamed on production problems and strikes by machinists.

The aeroplane’s first flight has been put off until the second quarter of 2009, and will not start shipping until a year later. This is the 787’s fourth delay, and the aircraft is already two years behind schedule.

Boeing suggests that its financial outlook for 2009 will affected by the postponement.
