hard to find rich info about Nivre parser, google lead to Maltparser, is it the same?
is it the one mentioned in the paper Parsing to Stanford Dependencies Trade-offs between speed and accuracy?
it performs quite well in the paper, why is it so unpopular?
The MaltParser is the implementation of all the algorithms published by Nivre et al. So whenever experimental data is reported for the Nivre algorithm(s), it is probably the result of running the MaltParser.
