I am trying to use dictionary for alignment using GIZA++. I have observed that even thought I ask GIZA to do so (using a command line), the output does not change. The model parameters without using the dictionary and after using the dictionary are same. When I looked into the source code, I found a flag indicating GIZA to use dictionary which is NEVER set to TRUE. When I changed the code to set the flag, I found GIZA using the dictionary in the exact opposite way. The score of the words which are in the dictionary went lower! Did anyone face a similar problem? Am I supposed to set occurance of sentence in .snt file (first line in every sentence pair) to -1? I appreciate if someone could shed some light on this.
