New Year, New Skills: Get Ready For The Future With MOOCs

Was one of your New Year’s resolutions to build up your knowledge, skills and talents for the new digital world? If so, there are plenty of online options to help you achieve your goals, and at no cost to you, from the crop of MOOCs (massive open online courses) that’s sprung up.

The Semantic Web Blog scoured some of them to present you with some possible courses of study to consider in pursuit of your goals:

Coursera:

  • Data scientists-in-training, Johns Hopkins Bloomberg School of Public Health assistant professor of biostatistics Jeff Leek wants to help you get a leg up on Big Data – and the job doors that understanding how to work with it opens up – with this applied statistics course focusing on data analysis. The course notes that there’s a shortage of individuals with the skills to find the right data to answer a question, understand the processes underlying the data, discover the important patterns in the data, and communicate results to have the biggest possible impact, so why not work to become one of them and land what Google chief economist Hal Varian reportedly calls the sexy job for the next ten years – statistician (really). The course starts Jan. 22.
  • We’ve seen a lot about robots in the news over the last month, from the crowd-funded humanoid service robot Roboy, the brainchild of the Artificial Intelligence Laboratory of the University of Zurich, to Vomiting Larry, a projectile vomiter developed to help scientists to better understand the spread of noroviruses. If you’d like to learn about what’s behind robots that can act intelligently (sorry, Larry, but you might not qualify here), you want to learn more about AI. And you can, with a course starting Jan. 28 taught by Dr. Gerhard Wickler and Prof. Ausin Tate, both of the University of Edinburgh.
  • Siri, where can I go to find out more about natural language processing? One option: Spend ten weeks starting February 11 learning about NLP with Michael Collins, the Vikram S. Pandit Professor of Computer Science at Columbia University. Students will have a chance to study mathematical and computational models of language, and the application of these models to key problems in natural language processing, with a focus on machine learning methods.

Blekko Data Donation Is A Big Benefit To Common Crawl

Common Crawl, the non-profit organization creating a repository of openly and freely accessible web crawl data, is getting a present from search engine provider blekko. It’s donating its metadata on search engine ranking for 140 million websites and 22 billion webpages to Common Crawl.

“The blekko data donation is a huge benefit to Common Crawl,” Common Crawl director Lisa Green told The Semantic Web Blog. “Knowing what the blekko team is crawling and how they rate those pages allows us to improve our crawler and enrich our corpus for high-value webpages.”

Noam Chomsky & Peter Norvig on the Path of AI

Yarden Katz of The Atlantic recently shared Noam Chomsky’s thoughts on where the acclaimed linguist thinks that artificial intelligence has gone wrong. Katz writes, “In May of last year, during the 150th anniversary of the Massachusetts Institute of Technology, a symposium on “Brains, Minds and Machines” took place, where leading computer scientists, psychologists and neuroscientists gathered to discuss the past and future of artificial intelligence and its connection to the neurosciences. The gathering was meant to inspire multidisciplinary enthusiasm for the revival of the scientific question from which the field of artificial intelligence originated: how does intelligence work? How does our brain give rise to our cognitive abilities, and could this ever be implemented in a machine?”

He goes on, “Noam Chomsky, speaking in the symposium, wasn’t so enthused. Chomsky critiqued the field of AI for adopting an approach reminiscent of behaviorism, except in more modern, computationally sophisticated form. Chomsky argued that the field’s heavy use of statistical techniques to pick regularities in masses of data is unlikely to yield the explanatory insight that science ought to offer. For Chomsky, the ‘new AI’ — focused on using statistical learning techniques to better mine and predict data — is unlikely to yield general principles about the nature of intelligent beings or about cognition.”

Katz adds, “This critique sparked an elaborate reply to Chomsky from Google’s director of research and noted AI researcher, Peter Norvig, who defended the use of statistical models and argued that AI’s new methods and definition of progress is not far off from what happens in the other sciences.”

Bridging Words and Meaning at Google

Valentin Spitkovsky and Peter Norvig of the Google Research Team have posted an article about their new paper on dictionaries for linking text, entities, and ideas. They write, “Human language is both rich and ambiguous. When we hear or read words, we resolve meanings to mental representations, for example recognizing and linking names to the intended persons, locations or organizations. Bridging words and meaning — from turning search queries into relevant results to suggesting targeted keywords for advertisers — is also Google’s core competency, and important for many other tasks in information retrieval and natural language processing. We are happy to release a resource, spanning 7,560,141 concepts and 175,100,788 unique text strings, that we hope will help everyone working in these areas.” Read more

Google Director of Research on Search Algorithms & AI

Google Director of Research Peter Norvig recently answered questions about Google’s search algorithms. Norvig stated, “We test tens of thousands of hypotheses each year, and make maybe one or two actual changes to the search algorithm per day. That’s a lot of ideas, and a lot of changes. It means the Google you’re using this year is improved quite a bit from the Google of last year, and the Google you’re using now is radically different from anything you used ten years ago.” Read more

Popular Stanford Course on AI Offered Online

Sebastian Thrun and Peter Norvig are teaching an online course entitled Introduction to Artificial Intelligence from September 26 through December 16, 2011. The course, also taught in-class at Stanford University, is a popular intro level examination of AI. “For the online version,” the description states, “the instructors aim to offer identical materials, assignments, and exams, and to use the same grading criteria. Both instructors will be available for online discussions.” Read more

Siri: The Virtual Assistant That Will Make Everyone Love The
TechCrunch, CA
It has roots in Apple’s famous “Knowledge Navigator” video, and in the original intelligent agents and DARPA work that inspired the invention of the Semantic Web. Even luminaries such as Google’s own Peter Norvig have worked on agents in the past.
