    Hi,

    Can anybody explain result below but I have.. I could not understand any of it. I delete repeated output with ……… to make the question a bit smaller. Hope I will get answer sooner

    Everything before "Test partition 1" are logs/debug outputs by minorthird and the specific learning algorithm - in this case VotedPerceptron. You can learn more about voted perceptron by using google scholar.

    Test partition shows you the evaluation of the performance of the extractor on the particular test partition. You can read about the different between Token- and Span- Precision and Recall on a previous thread:

    https://sourceforge.net/projects/minorthird/forums/forum/358215/topic/2826472

    The overall performance is the same as the test partition 1 because you have only 1 test partition.
