Hi,
You can use bin/query on an ARPA or KenLM file. Then just type
sentences at it (or use a file as stdin). By default it will assume you
are scoring sentences. You can pass -n to not wrap in <s> and </s>.
It appears that you are asking to score sentence fragments. The
leading words will be scored using unigrams, bigrams, etc. from, say, a
5-gram model. If you are using Kneser-Ney, these lower-order
probabilities (unigrams through 4-grams) are conditioned on having
backed off to them. If you want accurate scores for sentence fragments,
build a model of order 1, order 2, order 3, etc. then combine them using
build_binary -r "1.arpa 2.arpa 3.arpa 4.arpa" 5.arpa 5.rest
You can then use
bin/fragment 5.rest <fragments
to attain log10 frequencies. For more on this rant, read
