Some common use examples for Ace, illustrated with Jacy:
For the full list of command line options see AceOptions. For some discussions of picking best values for the ERG, see AceErgTuning.
Prepare for parsing, outputting only the top best MRS, nicely formatting the output (one EP per line)
$ ace -g grammar.dat -Tf1
$ 犬 が 吠える
SENT: 犬 が 吠える
[ LTOP: h0

NOTE: 1 readings, added 183 / 63 edges to chart (22 fully instantiated, 26 actives used, 11 passives used) RAM: 1327k
With sensible limits and using tnt for POS tagging (which enables unknown word processing).
cat FILE | ace --max-chart-megabytes=1920 --max-unpack-megabytes=2048 --tnt-model wsj.tnt -g eng.dat -Tf -n 10
Pipe parse output into generation:
$ ace -g grammar.dat -Tf1 | ace -g grammar.dat -e
$ 犬 が 猫 を 追う 。
NOTE: 1 readings, added 323 / 101 edges to chart (31 fully instantiated, 37 actives used, 17 passives used) RAM: 1996k
犬 が 猫 を 追う
猫 を 犬 が 追う
NOTE: 85 passive, 431 active edges in final generation chart; built 88 passives total. [2 results]
This produces the compiled grammar.
$ ace -G grammar.dat -g path-to/config.tdl
When you compile a grammar, ace gives you a brief summary:
2057 types (601 glb), 16751 lexemes, 63 rules, 12 orules, 52 instances, 22622 strings, 168 features
These refer to (FCB thinks):
| types | number of non-leaf types | of which X are created by ace as glbs |
| lexemes | lexical items | |
| rules | grammar rules | |
| orules | inflectional rules | ?both with and without orthographic effect |
| instances | ??? | everything else: roots, chart-mapping rules, ??? |
| string | distinct strings | |
| features | distinct features |
The YY input mode (see the corresponding section in PetInput) allows you to pass information such as POS tags.
cat yy.txt | ace -g erg1214.dat -y
where yy.txt contains inputs like:
(42, 0, 1, <0:11>, 1, "Tokenization", 0, "null", "NNP" 0.7677 "NN" 0.2323)
