Parsing jumping jacks

What could be common between Computational Linguistics and Aerobics? Quite a lot, as it turns out to be.

Dance descriptions, while not really in English do have a regular structure and can be thought of as a sub-language with full set of syntactic, semantic and pragmatic levels.

There are basic words of the language (move names), correct ways of putting them in a sentence (a routine) and all the way up to good flowing text (classes that do not hurt the participants).

I was thinking about relationship between dance instructions and computational linguistics in context of Scottish Country Dancing for at least a year. My imagined benefits were that codified dance instructions would allow for automatic dance animations, superior teacher aids and other applications that currently require a lot of sweat and toil. Dance evening programmes that are currently put together manually for each event, could be assisted with automated evaluation pointing out awkward sequences of dances.

Unfortunately, my attempts at explaining the connection made no sense to the people around me. So, I was ecstatic to discover that such a link was already discovered by others before me.

Adam Bull, more than 10 years ago, has tried to apply principles of computational linguistics to Aerobics for his MPhil degree in the paper entitled The formal description of aerobic dance exercise – a corpus-based computational linguistics approach. While, the report is not complete, it puts down many of the same arguments I have tried myself.

Unfortunately, the electronic copy of the document was not available. After some effort, I got in touch with Adam and he send me the copy of the report with the permission to distribute. I have put a copy of it on my own server.

I hope his research will get rediscovered and improved upon. That way when I get some time to apply my own PhD skills to Scottish Country Dancing, there will be more than one person on whose shoulders I would be able to stand.

Pictures from RSCDS ball in Moscow

Scottish Country Dancing is everywhere. Moscow is a fairly recent branch, so they are all bright and eager. I do not dance with them, but do read their online public journal, to see what kind of issues a non-English speaking dancers would run into.
There was a dancing event there recently and the photos from that event are now available online (1 and 2). One does not need to understand Russian, to enjoy the photographs of young people dancing and generally showing off.

The podcasts I listen to and how BusinessWeek got it wrong

Is Podcasting revolution over before it began? BusinessWeek seems to think so and quotes Pew Internet & American Life Project’s statistics. The topic is also generating some buzz in the blogosphere, with BusinessWeek’s interpretation being gleefully accepted by some and thoughtfully rejected by others.

I believe into podcasting‘s future because it is here already for me. I have a 40 minute walk to work each day, so I have over six hours of content a week I can consume. And being quite busy during days, nights and weekends, I try to use that walk time constructively as well. I have been listening to the podcasts from before they were called that and, so, had some time to get my bearings. And they are basically aligned with what the concept of Long Tail teaches us.

Strangely enough, BusinessWeek did not even mention any of the concepts that are important for me and my podcast consumption. That’s how I know the article is missing many points. It is not really unexpected, as it takes a while to get past the beginner’s understanding and actually see the real depth of the concept.

My current collection is at 25 podcasts and I have discarded over time probably twice that number. Less than a third of the podcasts on the list would be considered even vaguely popular by normal measures, the rest are plainly hyper-specialized to my needs and interests.

Over time, I had dutifully sampled and eventually discarded Adam Curry, Dave Winer and Gillmor Gang podcasts. They sporadically have some interesting content, but so infrequently that I find myself frustrated with all the filler. Gillmor Gang specifically I have given 3 or 4 tries over years, but I think they were most interesting during their ITConversations’ days.

I also don’t have any popular radio podcasts. I find the latest news to be easiest to consume in an aggregated or RSS format on my computer. That way if a news item is interesting, I can follow up on its references or setup keywords alert for the future notifications. Podcasts, in my mind, are much more suitable for content that has already undergone some thought process by its producer. I know that for some people, the reasoning is different but just as valid (for them).

I break my subscriptions into roughly 5 categories:

  • Technical News – In my industry (IT) it takes all the running you can do, to keep in the same place. Without these podcasts I feel that I would not notice what is coming down the line until it would be too late and I would be stuck maintaining Cobol-equivalent systems forevermore.
  • Trend watching – Many interesting things are happening in the world if one just happens to be in the right place at the right time. These podcasts put me into that place and do it very early in the ideas’ lifecycles: somewhere between a cutting edge and an early adoption stage. I may not have time to participate, but sometimes the knowledge I get allows me to leapfrog the conventional process. For example, I have been on a cheap Voice-over-IP service (Lingo) for nearly two years and saved myself money and hustle of dealing with Verizon and its ilk.
  • Learning new skills in a background – I may not have time to allocate several active hours a week on a useful, but not currently essential skill, but podcasts in these category allow me to learn something through osmosis over time. Later, when I would need those skills, I would have already absorbed enough to be a very quick learner.
  • Language learning – I am studying Spanish now and before that I was learning French and Esperanto and there is always some improvement I could do to my English. These podcasts provide additional learning (or meta-learning) material. Some of them are also good edutainment.
  • Entertainment – Some podcasts are just funny or interesting or have my friends in them. They round up the collection nicely.

My full list is available publically, but here is the breakdown by the categories as I see it:

Are there more podcasts I would have liked to listen to? Certainly. I would love a podcast on computational linguistics. At the moment, even the bloggers on the topics are extremely rare.

I would also love a podcast on Scottish Country Dancing. There is just so much one could do with that. I know that at least one person have thought of it and given up as unsustainable, which is a real pity. I am tempted to start one myself just to prove her wrong.

Finally, I think there is a way to make a better language-learning podcast/video cast than the ones I found so far. I have mentioned some of the ideas to at least one person in a position to do that. Nothing happened yet, but such things take time. I will wait a while and, if nothing happens, will blog it here instead. I don’t mind prividing competitive advantage to a company that deserves it through good service, but will not sit on the ideas forever either.

To summarise the long post, I think that podcasting has legs and will succeed in the content niches that appeal to people based on their individual interests and needs. There is a lot of fluff and junk podcasts on the web at the moment, but it is getting better and, as with blogging, the absolute number of interesting podcasts is growing fast. It takes some time to find good content, but it really pays off in a long run.
