How can I access words from a given index ?

[neshkatrapati]

Is reverse lookup supported ?.

[kpu]

No. Most use cases want to be able to recover the original word even if it's not in the vocabulary. Which won't work if all unknowns are mapped to 0. There are two options: remember words as they go in or load all words at the beginning. Loading all words at the beginning can be done by reading lm/enumerate_vocab.hh.

Okay, Is there a simple way for me to loop through all the n-grams of a specified order ?, sort of like an iterator ?

[kpu]

Yes, but only at loading time because the original strings are not stored in memory. Read lm/enumerate_vocab.hh .

You can also find them null-delimited at the end of a binarized model file.
