ancast 0.1.0

AnCast++ metric for evaluating UMR semantic graphs

Ancast

AnCast metric for evaluating UMR semantic graphs.

Install

ancast is currently available as a local, editable install only

$ pip install -e .

Usage

Consider sample AMR/UMR files in samples dir

CLI command

Currently, output file path is required and will contain analysis csv file.

$ ancast --help

options:
  -h, --help            show this help message and exit
  -p PRED [PRED ...], --pred PRED [PRED ...]
                        (required) path to prediction file or dir (if dir, same filenames must exist in `gold`)
  -pe PRED_EXT [PRED_EXT ...], --pred-ext PRED_EXT [PRED_EXT ...]
                        if `args.pred` flag is a dir, which file extensions to consider
  -g GOLD [GOLD ...], --gold GOLD [GOLD ...]
                        (required) path to gold file or dir (if dir, same filenames must exist in `pred`)
  -ge GOLD_EXT [GOLD_EXT ...], --gold-ext GOLD_EXT [GOLD_EXT ...]
                        if `args.gold` flag is a dir, which file extensions to consider
  -o OUTPUT, --output OUTPUT
                        (optional) path to output analysis files(if new dir, should not contain comma in the base dirname)
  -s {snt,doc}, --scope {snt,doc}
                        whether to run ancast over AMR/UMR sentence-level graphs (`snt`) or to run ancast++ over UMR document-level graphs (`doc`)
  -df {amr,umr}, --data-format {amr,umr}
                        whether the input data are AMR(s) or UMR(s) (automatically set to `umr` if `--scope` is `doc`)
  -c CNEIGHBOR, --cneighbor CNEIGHBOR
                        coefficient for the importance of neighborhood information when broadcasting
  -sc SENSE_COEFFICIENT, --sense-coefficient SENSE_COEFFICIENT
                        importance of sense ID when comparing two concepts
  --separate-1-and-2 [SEPARATE_1_AND_2]
                        whether to combine one-hop and two-hop neighbors together
  --allow-reify [ALLOW_REIFY]
                        whether to apply reification before comparing graphs
  --use-alignment [USE_ALIGNMENT]
                        whether to use alignment information when establishing anchors
  --use-smatch-top [USE_SMATCH_TOP]
                        whether to add (TOP :root `ROOT_NODE`) edge
  --weighted {snts,toks}
                        whether to apply weighted average for ancast++ doc-level evaluation by (1) number of sentences or (2) number of tokens
  --seed SEED           random seed for reproducibility
  --debug               debug logging mode

Python API

evaluate accepts the same set of arguments described above.

from ancast import evaluate

pred_fpath = "./samples/umr_test.txt"
gold_fpath = "./samples/umr_gold.txt"
out_fpath = "./samples/outputs"

out = evaluate(
    pred_fpath,
    gold_fpath, 
    out_fpath, 
    scope="doc"
)
