openNLP v/s sharpNLP

[vinay ds]

I tried POS tag with both c# and java.

But for some words i am getting different results.  For example : "melting
point" .

In C# (using sharpNLP model) i am getting result : [NN,NN]

but,

In java, (using openNLP 1.5 model) i am getting result : [VBG,NN] .



Are these kind of difference expected. which one i should follow ?



Thanks in advance,

Vinay
