[SRILM User List] Why there are "_meta_1" in LM?

[Meng CHEN]

Hi, I trained LMs with the write-binary-lm option, however, when I converted the LM of bin format into arpa format, I found there were 4 more 1-grams in the arpa LM as follows:
-8.988857 _meta_1
-8.988857 _meta_2
-9.201852 _meta_3
-9.201852 _meta_4
In facter, these four words do not exisit in my vocab. So where are they come from? What should I do to remove them ?
Thanks!
