People using our results
« on: March 01, 2013, 11:27:01 am »
We've produced an impressive batch of results since we started the project, and I'm sometimes asked what, exactly is being done with them all. Some of the results, like those I've posted on the blog, and the ship histories on navalhistory.net, you already know about, but we are starting to have a much wider impact.

Weather & Climate:

There are at least 5 major climate reconstructions currently in progress using our new weather observations:

Ship histories:

New museum exhibits inspired by or involving our work are in planning or preparation at:

Rule one of any project is "It always takes longer than you think - even after allowing for rule one", and that's certainly true here - none of this work is finished yet. But we've plenty to look forward to, and I'm confident that even more uses will emerge.

That's really great to know Philip - should send us all back to transcribing with renewed vigour!

 :D :D

It's always a great feeling to discover that all the hard work everyone is doing here (from the trascribers to moderators, historians, and all the people involved) is relevant and useful for so many other projects around the world... it makes feel us even more proud of all of our efforts!

Thanks for sharing this philip!! And congrats to all OW!

:D :D

Great news. Having done a few blocks of ship history I am conscious of the number of days of weather which either do not have a location or where the location is inaccurate and I hope that a mechanism exists to add in our 'improved' location data to the various databases so that the weather transcriptions can be used to their full value.

I must admit that I find more affinity with our RN data than the North American ships and would put in a plea for some WW2 data to become available for the 75th anniversary of the outbreak of that war. Just a thought.

See Unalga I - http://forum.oldweather.org/index.php?topic=3332.msg55796#msg55796

And  since she spent WW2 in the Caribbean, I wouldn't be surprised if another ship shows up who did the arctic during that war.

Thanks for the update! Please let us know if you hear more about the museum exhibits, it would be great to be able to visit them.

Cor - I didn't realize quite how much we were being used (which is, btw, a sign of OW addiction - didn't get snout out of OW bucket to notice that world still rotates  ::))
How on earth do you keep up with it all Philip?
You're doing a great job.
I feel proud to be involved.

It's very interesting to read about the applications of the OW data. Thanks for this, Philip!

Of COURSE the world rotates Joan. It rotates around US!!! ;D ;D (Actually it REVOLVES around US - it rotates itself! ;))


An HONOUR and a PRIVILEGE to be associated with you, Philip. And ALL my OW friends! I have learned much and feel humbled to know what we have contributed to the World supply of knowledge!

I'm interested to know, as there have been a couple of occasions where I'm not 100% confident, what is the process once a log has been sent to you? How do you account for major outliers. Its reassuring to know that there are many people working on the same log. Do you have to check every log again or is it only if there are glaring errors? eg if a ship jumps from USA to china and back again in a single day. Do you use a whole groups transcriptions for a log to find the average?

The short answer for most of those questions is that each page is transcribed by OldWeather three times, and so on average most mistakes should be limited to only one transcriber. I believe that the data processing also looks for outliers in the numbers - I don't know if there's any posts (either here or on the blog) about the data analysis after transcription?

Hi, B_L_Parfitt, welcome to OldWeather!

Danny beat me to an answer, the short reply to him is that he is correct.  :)

If 2/3rds of the transcribers agree, the computer accepts the data as automatically good.  There are also algorithms for finding correctly transcribed errors that break the accepted pattern, which then get kicked out for human consideration.  The details of what happens to data points that get kicked out of the "automatically OK" class will have to be explained by Philip.

He did do a blog some time ago showing that our transcription record has fewer errors in it than the error rate of the original log keeper's records we are recording!  While we have moved on to different ships, the statistical use of at least 3 transcribers remains unchanged.
