Knowtator 1.7.1 removed

If you downloaded version 1.7.1 you may have noticed a most heinous bug that was introduced into this version that makes it impossible to begin a new annotation project. We are working hard to resolve this problem and will will release a new version as soon as we do. Please use version 1.7.0 for now. Thanks.

Full text annotation support coming to Knowtator 1.5

I have started using the 'Group' attribute for bugs and feature requests for Knowtator related tickets. If you want to see which bugs have been or will be fixed for version 1.5, then just select the group category "knowtator 1.5". Same holds for the feature requests.

In summary there are many layout changes and other UI changes to faciliate full-text annotation (documents larger than a couple of sentences.) Please check out the feature requests tracker, select group "knowtator 1.5" to see what's coming soon.

Where is Knowtator going?

For those of you who have downloaded and installed Knowtator I would like to say thank you for your interest. I am interested to know who you are so please drop a line and tell me who you are. I would also like to know if you think you might use Knowtator for an annotation project - or if there are specific things that you find lacking in this tool. I realize that this tool is missing a lot of bells and whistles that will make executing a real text annotation project possible and easy. I thought I would take a moment to describe where Knowtator is going. ... read more
