Parser output on shell is different from the demo output

[paridhij]

I tried a sentence "DES reduces the risk of recurrent MI, CV death and all-cause mortality" on the TurboParser online demo and the downloaded TurboParser2.3.0. I am using parse.sh to get the conll format of the parse tree. Here are the outputs:

Demo output [which is correct]:
1 DES _ NN NNP _ 2 nsubj _ _
2 reduces _ VB VBZ _ 0 null _ _
3 the _ DT DT _ 4 det _ _
4 risk _ NN NN _ 2 dobj _ _
5 of _ IN IN _ 4 prep _ _
6 recurrent _ JJ JJ _ 7 amod _ _
7 MI _ NN NNP _ 5 pobj _ _
8 , _ , , _ 7 punct _ _
9 CV _ NN NNP _ 10 nn _ _
10 death _ NN NN _ 7 conj _ _
11 and _ CC CC _ 7 cc _ _
12 all-cause _ JJ JJ _ 13 amod _ _
13 mortality _ NN NN _ 7 conj _ _

while the TurboParser2.3.0 installed version gives:

1 DES _ NNP NNP _ 2 SUB
2 reduces _ VBZ VBZ _ 0 ROOT
3 the _ DT DT _ 4 NMOD
4 risk _ NN NN _ 2 OBJ
5 of _ IN IN _ 4 NMOD
6 recurrent _ JJ JJ _ 7 NMOD
7 MI _ NNP NNP _ 13 NMOD
8 , _ , , _ 13 P
9 CV _ NNP NNP _ 13 NMOD
10 death _ NN NN _ 13 NMOD
11 and _ CC CC _ 13 NMOD
12 all-cause _ NN NN _ 13 NMOD
13 mortality _ NN NN _ 5 PMOD

Lines 8,9,10,11 have wrong dependencies, and node 13 has incorrect head. What am I missing here.

I also tried with all the tree models, basic, full and standard. None of the models give the results demo gives.

Can you please look into the discrepancy?

Hi,

Which demo are you refering to? http://demo.ark.cs.cmu.edu/parse?

The reason for the discrepancy is that you are using two different models.
Note that the dependency labels are different (Stanford dependencies in the
first example, in the demo model; Yamada-Matsumoto dependencies in the
second one, your local model). To get the same dependencies as the demo,
please contact Lingpeng Kong (CC'ed) who may be able to point you to the
model being used at the demo.

Thanks,

André

Thanks Andre.

Is the problem solved? Actually I also want the Turbo parser being used in the demo. Could you also put this version online? Thanks much!

(Update: Already got the demo version. Thx!)

I am also very interested to get the Turbo parser used in the demo.
http://demo.ark.cs.cmu.edu/parse
This is so far the most accurate parser for my corpus.
