in the sample from http://www.statmt.org/moses/download/sample-models.tgz the phrase table contains only one feature score
while when you train your own phrase table using the Moses training script you produce a PT with 5 feature scores, becuase this is the default of Moses. if you want to use such PT, you have to change your configuration file accordingly: - the third field of the "ttable-file" parameter should be 5 (scores)) - specify 5 TM weights something like the following.... regards, nicola # translation tables: source-factors, target-factors, number of scores, file [ttable-file] 0 0 5 phrase-table # translation model weights [weight-t] 1 1 1 1 1 On 11/10/09 11:09 AM, "Kranthi Achanta" <[email protected]> wrote: Hello All, We downloaded the sample phrase table & language model from the Moses website: http://www.statmt.org/moses/?n=Moses.Tutorial and tried passing this phrase table to the decoder that we built in windows machine. We have given the input sentence 'das ist ein klein haus' to the decoder and it worked well giving the output as 'this is a small house'. Problem: Now, we tried generating a similar phrase table using the above attached input files '' and it generated the phrase table as attached ''. We see a vast difference between the 2 phrase tables and the probabilities are also different from the same phrase table. And when we ran the decoder using this phrase table, we got the following Error: 'ERROR:Size of scoreVector != number (5!=1) of score components on line 1'.

I could build the decoder exe and phrase table for some sample corpus, but when I try executing the decoder for a small French sentence using the generated phrase table, I always get 'ERROR:Size of scoreVector != number (5!=1) of score components on line 1' which I do not understand. I tried building phrase tables atleast 5 times on different corpus each time but still I get the same error. Please find the attached error log and assist me what went wrong and let me know if you need to know any other details further.
