<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV> I tried to build class based LMs in the following way:</DIV>
<DIV> </DIV>
<DIV> step-1: ngram-class -text test.in -numclasses 100 -class-counts text.cnt -classes text.cls -save 100</DIV>
<DIV> </DIV>
<DIV> step-2: ngram-count -read text.cnt -memuse -kndiscount -kndiscount1 -kndiscount2 -lm text.srilm.gz</DIV>
<DIV> </DIV>
<DIV> I found that the class count output "text.cnt" from step-1 is only bigram-counts. Thus the final class-LM text.srilm.gz is also a bigram one. </DIV>
<DIV> </DIV>
<DIV> Could anyone tell me if I am using the toolkit correctly? How to build a trigram class-based LM? Also are there any published paper/document that I can look up for detail information? </DIV>
<DIV> </DIV>
<DIV> Many thanks,</DIV>
<DIV> </DIV>
