Well I took a look at U-Compare and found the display gave me an error when I loaded a large file. I started looking at the code to solve the problem only to discover the source is only partially open. I am not keen on reporting the error as if I did I would need to say what the file was. I do not want to encourage people onto my work area too soon. So I understand the reasons for the non-open source but I am frustrated.
In looking around for a UIMA / Brat integration I have found the fully open source WebAnno project. They have youtube tutorial videos on this product. The server version installs on Debian a unix variant. I am tempted to move to unix, I worked on unix years ago, but it is a lot of extra learning I do not need. Then the question is whether to go for a dual boot on my laptop or to get another system. I will try running on Windows first.
