ngramrandgen — generate random sentences from a language model

Synopsis

ngramrandgen [Options] [in.fst [out.far]]

Description

Generate random sentences from a language model.

Options

Boolean options accept either true or false as a value, or the default value if neither value is specified.

--end_symbol=STRING

Class label for sentence end.  Default: "</s>".

--fst_align[=BOOLEAN]

Write FST data aligned where appropriate.  Default: false.

--fst_compat_symbols[=BOOLEAN]

Require symbol tables to match when appropriate.  Default: true.

--fst_default_cache_gc[=BOOLEAN]

Enable garbage collection of cache.  Default: true.

--fst_default_cache_gc_limit=INT64

Set the cache byte size that triggers garbage collection.  Default: 1048576.

--fst_error_fatal[=BOOLEAN]

If true, FST errors are fatal.  Otherwise, returned objects are flagged as bad. For example, FSTs are returned with the kError property set to true, and FST weights set so that Member() returns false.  Default: true.

--fst_field_separator=STRING

Set the characters used as a separator between printed fields.  Default: " ".

--fst_read_mode=STRING

Default file reading mode for mappable files, "read" to use read(2) or "map" to use mmap(2).  Default: "read".

--fst_verify_properties[=BOOLEAN]

Verify fst properties queried by TestProperties.  Default: false.

--fst_weight_parentheses=STRING

Set the characters enclosing the first weight of a printed composite weight (e.g., pair weight, tuple weight, and derived classes) to ensure proper I/O of nested composite weights.  Must have size 0 (none) or 2 (open and close parenthesis).  Default: no parentheses.

--fst_weight_separator=CHARACTER

Set the character separator between printed composite weights.  Default: comma.

--help[=BOOLEAN]

Show usage information.  Default: false.

--helpshort[=BOOLEAN]

Show brief usage information.  Default: false.

--max_length=INT32

Maximum sentence length.  Default: 2147483647.

--max_sents=INT64

Maximum number of sentences to produce.  Default: 1.

--ngram_error_fatal[=BOOLEAN]

If true, NGram errors are fatal.  Otherwise, returned objects are flagged as bad; i.e., NGramModel::Error() returns true.  Default: true.

--remove_epsilon[=BOOLEAN]

Remove epsilons from generated strings.  Default: false.

--remove_total_weight[=BOOLEAN]

Remove total weight when output weighted.  Default: false.

--save_relabel_ipairs=FILENAME

Save input relabel pairs to file.  Default: do not save.

--save_relabel_opairs=FILENAME

Save output relabel pairs to file.  Default: do not save.

--seed=INT32

Randomization seed.  Default: random seed.

--start_symbol=STRING

Class label for sentence start.  Default: "<s>".

--tmpdir=PATHNAME

Set the temporary directory to use.  Default: /tmp.

--v[=INT32]

Set the verbosity level.  Default: 0.

--weighted[=BOOLEAN]

Output tree weighted by sentence count versus unweighted sentences.  Default: false.
