ClozeFox Update: Let’s go to Texas! :-)

   Posted by: Emre Sevinc   in jetpack4l

ClozeFox project has been selected for the final phase of Mozilla Jetpack for Learning Design Challenge.

I’ll be attending Jetpack for Learning Design Camp and then the SXSW Interactive conference at Austin, Texas during the second week of March. I’m really thankful to our mentors from Mozilla as well as the other challenge participants who provided feedback and technical support (and also to my beloved one who was really patient as I told her to do same recording for the 5th time ;-) .

To learn more about ClozeFox please read previous related entries at http://ileriseviye.org/blog/?tag=jet4learning.

Disclaimer: The plug in is still in pre-alpha stage and not intended for public use however if you want to give it a try the source code is fully available at http://github.com/emres/clozefox.

China: Ready to dominate the world of science?

   Posted by: Emre Sevinc   in Ekonomi-Politik, Science

Whenever I think of the best science centers in the world USA and EU states come to my mind. However after having read a very short article at NewScientist (’Get ready for China’s domination of science‘) , I began to wonder how long USA and EU would keep on being the attraction centers for the brightest minds. Take a look at the facts below and decide for yourself:

- Data from the Organisation for Economic Cooperation and Development shows that between 1995 and 2006, China’s gross expenditure on R&D (GERD) grew at an annual rate of 18 per cent. China now ranks third on GERD, just behind the US and Japan and ahead of any individual European Union state.

- China’s student population has reportedly reached 25 million, up from just 5 million nine years ago. China now has 1700 higher education institutions, around 100 of which make up the “Project 211″ group. These elite institutions train four-fifths of PhD students, two-thirds of graduate students and one-third of undergraduates.

- In 1998, China’s research output was around 20,000 articles per year. In 2006 it reached 83,000, overtaking the traditional science powerhouses of Japan, Germany and the UK. Last year it exceeded 120,000 articles, second only to the US’s 350,000.

- China produces 10 per cent of the world’s publications in engineering, computer sciences and earth sciences, including minerals. It now also produces 20 per cent of global output in materials sciences, with a leading position in composites, ceramics and polymer science and a strong presence in crystallography and metallurgical engineering.

- China is not doing science behind closed doors; its international collaborations are growing. Nearly 9 per cent of papers originating from Chinese institutions have a US-based co-author. Japanese and British co-authorship is also growing. Collaboration with South Korea and Singapore almost trebled between 2004 and 2008 and collaboration with Australia expanded too – signs, perhaps, of an emerging Asia-Pacific regional network.

Can you be fat and fit? Let’s get physical!

   Posted by: Emre Sevinc   in General

I have recently read a wonderful short article at New Scientist: http://www.newscientist.com/special/get-physical-nine-facts-about-fitness

DOES an activity have to get you out of breath to count as exercise? Do you really have to do half-an-hour a day? Is pumping iron a good way to keep your heart healthy? These are just some of the dilemmas many of us face when working out the best way to get fit. The good news is scientists do broadly agree on the best ways to get fit, they just haven’t been very good at telling us what they’ve discovered

One of the most striking part was: Can you be fat and fit?

In a study published in 2007 Blair recruited 2600 people of varying weight and timed how long they could run on a treadmill before becoming exhausted, a proxy for fitness (JAMA, vol 298, p 2507). Among those who were mildly obese, only a third met a common definition of being physically unfit, and only half of those who were moderately obese were unfit. Blair points out that measures of aerobic fitness – the body’s ability to deliver oxygen to the muscles – have nothing to do with the amount of fat tissue present.

In the 12 years during which the subjects were followed, Blair’s study found that the risk of dying was more closely linked to fitness than fatness. People who were fit but obese had a lower risk of dying than people who were unfit but of normal weight. That’s important, says Blair, because while many overweight people find it hard to get slim, they could still become healthier with more exercise. It’s a point he would like doctors to bear in mind when advising overweight patients.

I think this provides yet another reason for me to keep on running ;-)

Automatic Joke Generation

   Posted by: Emre Sevinc   in Linguistics, Lisp, Programlama

How to Write Original Jokes (Or Have A Computer Do It For You)

This is a Common Lisp code walkthrough for generating original jokes. You seed the generator with the knowledge about different objects, and it uses that vocabulary to generate unique jokes. All of the jokes are of the form: “What do you get when you cross X with Y?” This code was originally written for my CS288: An AI Approach to Natural Language Processing class at UC Berkeley in 2004.

Technopolis, het Vlaamse doe-centrum voor wetenschap en technologie in Mechelen, ontwikkelde samen met het departement Elektrotechniek van de K.U. Leuven de opstelling “Verraadt je stem je herkomst?”. Op basis van een kort tekstje dat door de bezoeker wordt voorgelezen, schat de computer in uit welke provincie hij of zij afkomstig is. Het resultaat is een grafische weergave die aanduidt welke provincies in welke mate invloed op je taal hebben.

Het ontwikkelen van de interactieve opstelling en de bouw ervan werd gefinancierd door STEVIN. STEVIN is een meerjarig onderzoeks- en stimuleringsprogramma voor Nederlandstalige taal- en spraaktechnologie dat gezamenlijk door de Vlaamse en Nederlandse overheid wordt gefinancierd. De bedoeling van het project was het ontwikkelen van een installatie die voor het brede publiek de mogelijkheden van taal- en spraaktechnologie demonstreert.

In de praktijk haalt het systeem dan ook een herkenningsgraad van zo’n 70%, wat beter is dan de mens. http://www.technopolis.be/nl/?n=1&e=21&s=168&exhibit=341&&thema=4
