Stop, Collaborate and…Vote! Help solve climate change with MIT’s Climate CoLab Project

Do you have an idea about how to approach climate change?  You’re not alone.  Thousands of other people around the world are coming up with potential solutions to one of the world’s most challenging problems, but until now they have not been able to easily connect. MIT’s Climate CoLab is attempting to change this by bringing together innovators from across the globe to collaborate and develop solutions to the problem of climate change.

The basic idea of the Climate CoLab is similar to Wikipedia or Linux in that it harnesses “micro-contributions from many people around the world,” as Laur Fisher the CoLab’s Community and Partnerships Manager describes.  To do this, the CoLab runs annual competitions, in which anyone can submit a proposal that addresses a climate change issue.  Members of the CoLab community, including general public and experts in the field, are then encouraged to provide feedback on the entries, and eventually expert judges select finalists. A second cycle of feedback then begins for the finalists to allow thorough development of the proposals, and in the end the public votes on the winners.  Fisher describes that the goal of the CoLab is to facilitate a “transparent contest.” She notes that “anyone can comment and everything is open.” This year’s competition is currently in its final round of judging, and all participants are encouraged to vote until the end of August on their favorite proposals.

This year, the Climate CoLab ran 18 different competitions that address different aspects of climate change – for example, there was a contest focused on hydraulic fracturing “fracking;” one was titled “urban adaptation: climate resilient cities;” and one addressed the efficiency of buildings. Proposals were submitted from around the world – from Asia, to Central and South America, and even Iceland – and the applicants came from all education levels and professions.  Fisher asserts that the CoLab needs this diversity of members “because the issue of climate change is such a global issue, but then it’s also complex – there’s no one solution.”

The winning proposals will be announced shortly after the voting ends, and the authors will be invited make presentations at the Climate CoLab’s yearly conference on November 6-7.  The conference is free for anyone to attend, and the theme this year is “Crowds and Climate,” focusing on the role crowds play in addressing climate change – an interesting topic for anyone involved in a citizen science project! At the conference, the next competitions will also be announced for those who are eager to submit a proposal.

Voting for this year’s proposals closes at midnight (EDT) on August 31. Get started!

Games With Words: Play On

By July 17th, 2013 at 4:13 pm | Comment

Imagine trying to uncover the meaning behind all the words in the English language. Well, that’s what dictionaries are for, right? Not quite. According to Joshua Hartshorne, the director of MIT’s Games With Words, our current understanding of any word is simply based on its relationship with other words. That’s precisely the problem.

To provide an analogy, imagine if you only recognized the color blue because you knew it wasn’t yellow, green, or red. You know it’s “lighter” than black but “darker” than white. You also know it’s similar to the color of the sky or ocean. But take these relationships away, and ask yourself–do you truly understand what blue is?

This is essentially what Games With Words aspires to investigate in language—the intrinsic meaning of words. Hartshorne’s interdisciplinary team of psychologists, computer scientists, and linguists are trying to characterize what verbs mean.

“Dictionaries notwithstanding, scientists really do not know very much about what words mean, and it is hard to program [computers] to know what the word means when you [yourself] actually do not know,” says Hartshorne. “Our best computer systems, like Google Translate and Siri, treat words as essentially meaningless symbols that need to be moved around.”

One component of Games With Words is Verb Corner, which aims to uncover the meaning of verbs, a particularly challenging subset of language. Choose from 6 different games and scenarios that you can tackle. The more questions you answer, the more valuable the questions you have already answered become. This is because Games With Words uses cutting-edge analysis techniques to estimate your biases (everyone understands language differently!) and simultaneously identify difficult questions. So, the more data they have from each person, the better these analyses work.

“Rather than try to work out the definition of a word all at once, we have broken the problem into a series of tasks. Each task has a fanciful backstory, […] but at its heart, each task is asking about a specific component of meaning that scientists suspect makes up one of the building blocks of verb meaning. In this, we are building on pioneering work by Ray Jackendoff, Steven Pinker, Beth Levin and many other linguists and psychologists.”

Hartshorne recalls that back in 2006 when he started doing web-based experiments, collecting data from groups of hundreds of people was impressive. Nowadays, with existing technology, it’s possible to collect data from groups in the thousands if not tens of thousands. The ability to do this only adds value to studies like Games With Words. However, one of the biggest challenges is still scope. Because this is such a massive undertaking (there are lots and lots of words), the Games With Words staff needs all the help they can get from citizen scientists like you. (Yes you, dear reader!)

“We realized very early that even with a small army, it would take us well past the ends of our careers to finish this project if we don’t attract enough citizen scientists.”

The Games With Words team will be sharing the results of the project freely with scientists and the public alike, and they expect it to make a valuable contribution to linguistics, psychology, and computer science.
