The fields of JSON output have the following meaning:
seq_len
The number of terminal symbols in the actual or predicted terminal symbol sequence.
wpredict_max
An upper bound on the number of correctly predicted terminal symbols.
npredict_actual
The number of correctly predicted terminal symbols contained in the predicted terminal symbol sequence.
npredict_ngram
The number of terminal symbols correctly predicted in the actual terminal symbol sequence by applying an n-gram approach. The program prints this field on passing the option --ngrams.
wpredict_rand
The number of correctly predicted terminal symbols in random mode.
The program prints this field on passing the option --prob-rand=FLOAT.
This field is equal to the argument of that option multiplied by the field seq_len
.
prob_wpredict_max
This field is equal to wpredict_max/seq_len
.
prob_npredict_actual
This field is equal to npredict_actual/seq_len
.
prob_npredict_ngram
This field is equal to npredict_ngram/seq_len
.
The program prints this field on passing the option --ngrams.
prob_npredict_rand
This field is equal to the argument of --prob-rand=FLOAT option. The program prints the field on passing this option.
efficiency_ngram, %
This field is equal to (npredict_actual-npredict_ngram)*100/(wpredict_max-npredict_ngram)
except for the following special cases: if npredict_actual<npredict_ngram
, this field is equal to 0; if npredict_actual>wpredict_max
, this field is equal to 100.
The program prints this field on passing the option --ngrams.
efficiency_rand, %
This field is equal to (prob_npredict_actual-prob_npredict_rand)*100/(prob_wpredict_max-prob_npredict_rand)
except for the following special cases: if prob_npredict_actual<prob_npredict_rand
, this field is equal to 0; if prob_npredict_actual>prob_wpredict_max
, this field is equal to 100.
The program prints this field on passing the option --prob-rand=FLOAT.
