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

Open NLP is several years more current than SharpNLP.

Ok. In openNLP i see 2 types of model. 1. perceptron model and 2. maxent model.
