The fifth largest city in US passed a significant soda tax proposal that will levy (征税)1.5 cents per liquid ounce on distributors.

Philadelphil's new measure was approved by a 13 to 4 city council vote. It sets a new bar for similar initiatives across the country. It is proof that taxes on sugary drinks can win substantial support outside super-liberal areas. Until now, the only city to successfully pass and implement a soda tax was Berkeley, California, in 2014.

The tax will apply to regular and diet sodas, as well as other drinks with adder sugar, such as Gatorade and iced teas. It's expected to raise $410 million over the next five years, most of which will go toward funding a universal pre-kindergarten program for the city.

While the city council vote was met with applause inside the council room, opponents to the measure, including soda lobbyists, made sharp criticisms and a promise to challenge the tax in court.

"The tax passed today unfairly singles out beverages — including low —and no-calorie choices," said Lauren Kane, spokeswoman for the American Beverage Association. "But most importantly, it is against the law. So we will side with the majority of the people of Philadelphia who oppose this tax and take legal action to stop it."

An industry-backed anti-tax campaign has spent at least $4 million on advertisements. The ads criticized the measure, characterizing it as a "grocery tax".

Public health groups applauded the approved tax as step toward fixing certain lasting health issues that plague Americans. "The move to recapture a small part of the profits from an industry that pushed a product that contributes to diabetes, obesity and heart disease in poorer communities in order to reinvest in those communities will sure be inspirational to many other places," said Jim Krieger, executive director of Healthy Food America. "indeed, we are already hearing from some of t

Professor Ashok Goel of Georgia Tech developed an artificially intelligent teaching assistant to help handle the enormous number of student questions in the online class, Knowledge-Based Artificial Intelligence. This online course is a core requirement of Georgia Tech's online Master of Science in Computer Science program. Professor Goel already had eight teaching assistants, but that wasn't enough to deal with the overwhelming number of daily questions from students.

Many students drop out of online courses because of the lack of teaching support. When students feel isolated or confused and reach out with questions that go unanswered, their motivation to continue begins to fade. Professor Goel decided to do something to remedy this situation and his solution was to create a virtual assistant named Jill Watson, which is based on the IBM Watson platform.

Goel and his team developed several versions of Jill Watson before releasing her to the online forums. At first, the virtual assistant wasn't too great. But Goel and his team sourced the online discussion forum to find all the 40,000 questions that had ever been asked since the class was launched. Then they began to feed Jill with the questions and answers. After some adjustments and sufficient time, Jill was able to answer the students' questions correctly 97% of the time. The virtual assistant became so advanced and realistic that the students didn't know she was a computer. The students, who were studying artificial intelligence, were interacting with the virtual assistant and couldn't tell it apart from a real human being. Goel didn't inform them about Jill's true identity until April 26. The students were actually very positive about the experience.

The goal of Professor Goel's virtual assistant next year is to take over answering 40% of all the questions posed by students on the online forum. The name Jill Watson will, of course, change to something else
