How to Run

Pre-processing

Downloading RAMS

Leverage on existing parsed RAMS to DyGIE++ in toolkit:

eai data pull dsta.eventextraction.datasets@latest data/

Preprocess RAMS data

ONEIE requires the data to be in its own format. We may transform data in the DyGIE++ format to ONEIE's format with:

python oneie/preprocessing/process_dygiepp.py -i data/rams/collated-data/default-settings/json/dev.json -o data/oneie/rams/collated-data/default-settings/json/dev.json

Arguments:

  • -i, --input: Path to the input file.
  • -o, --output: Path to the output file.
  • -b, --bert: Name of BERT model used for tokenization (default: bert-large-cased).

A sample DyGIE++ format:

{"doc_key":"nw_RC00e90a0209cf7c63e3faf5008f034002ef61cea93a159a31aa33e18e","sentences":[["Three","specific","points","illustrate","why","Americans","see","Trump","as","the","problem",":","1",")","Trump","has","trouble","working","with","people","beyond","his","base",".","In","Saddam","Hussein","'s","Iraq","that","might","work","when","opponents","can","be","thrown","in","jail","or","exterminated",".","In","the","United","States","that","wo","n't","fly",":","presidents","must","build","bridges","within","and","beyond","their","core","support","to","resolve","challenges",".","Without","alliances",",","a","president","ca","n't","get","approval","to","get","things","done","."]],"events":[[[[40,"life.die.n\/a"],[33,33,"victim"],[28,28,"place"]]]],"ner":[[[33,33,"victim"],[28,28,"place"]]],"relations":[[]],"_sentence_start":[0],"dataset":"rams"}

A sample ONEIE format after using preprocessing/process_dygiepp.py:

Note: There are some RAMS data without events (events are extracted from gold_evt_links). For example:

{"rel_triggers": [], "gold_rel_links": [], "doc_key": "nw_RC013008ad72d04b5e4cca4706cad5cc71c88b0df4615bd597df0e3cf0", "ent_spans": [], "language_id": "eng", "source_url": "http://www.huffingtonpost.com/entry/why-trump-should-peacefully-protest-clintons-victory_us_5809d9b7e4b0b1bd89fdb0bc", "evt_triggers": [[103, 104, [["personnel.elect.winelection", 1.0]]]], "split": "dev", "sentences": [["In", "addition", "to", "working", "alongside", "super", "-", "PACs", ",", "there", "\u2019s", "the", "latest", "saga", "of", "two", "Democratic", "operatives", "losing", "their", "posts", "because", "of", "a", "leaked", "video", "."], ["The", "Chicago", "Tribune", "explains", "the", "impact", "of", "this", "video", "in", "a", "piece", "titled", "Two", "local", "Democratic", "operatives", "lose", "jobs", "after", "video", "sting", "on", "voter", "fraud", ":"], ["Robert", "Creamer", ",", "husband", "of", "Rep.", "Jan", "Schakowsky", ",", "D", "-", "Ill", ".", ",", "and", "Scott", "Foval", "--", "two", "little", "-", "known", "but", "influential", "Democratic", "political", "operatives", "--", "have", "left", "their", "jobs", "after", "video", "investigations", "by", "James", "O'Keefe", "'s", "Project", "Veritas", "Action", "found", "them", "entertaining", "dark", "notions", "about", "how", "to", "win", "elections", "."], ["Foval", "was", "laid", "off", "on", "Monday", "by", "Americans", "United", "for", "Change", ",", "where", "he", "had", "been", "national", "field", "director", "."], ["Creamer", "announced", "Tuesday", "night", "that", "he", "was", "\"", "stepping", "back", "\"", "from", "the", "work", "he", "was", "doing", "for", "the", "unified", "Democratic", "campaign", "for", "Hillary", "Clinton", "."]], "gold_evt_links": []}

The resultant dataset size after conversion is:

ACE2005 to OneIE format

The prepreocessing/process_ace.py script converts raw ACE2005 datasets to the format used by OneIE. Example:

python preprocessing/process_ace.py -i <INPUT_DIR>/LDC2006T06/data -o <OUTPUT_DIR>
  -s resource/splits/ACE05-E -b bert-large-cased -c <BERT_CACHE_DIR> -l english

python preprocessing/process_ace.py -i <PATH_TO_ACE>/data -o input/preprocessed_ace -s <PATH_TO_SPLITS> -l english -b <transformers model, eg. albert-xxlarge-v2> --time_and_val

Arguments:

  • -i, --input: Path to the input directory (data folder in your LDC2006T06 package).
  • -o, --output: Path to the output directory.
  • -b, --bert: Bert model name.
  • -c, --bert_cache_dir: Path to the BERT cache directory.
  • -s, --split: Path to the split directory. We provide document id lists for all datasets used in our paper in resource/splits.
  • -l, --lang: Language (options: english, chinese).

Training

  • cd to the root directory of this package
  • Set the environment variable PYTHONPATH to the current directory. For example, if you unpack this package to ~/oneie_v0.4.5, run: export PYTHONPATH=~/oneie_v0.4.5
  • Run this commandline to train a model: python train.py -c <CONFIG_FILE_PATH>.
  • We provide an example configuration file config/example.json. Fill in the following paths in the configuration file:
    • BERT_CACHE_DIR: Pre-trained BERT models, configs, and tokenizers will be downloaded to this directory.
    • TRAIN_FILE_PATH, DEV_FILE_PATH, TEST_FILE_PATH: Path to the training/dev/test files.
    • OUTPUT_DIR: The model will be saved to sub folders in this directory.
    • VALID_PATTERN_DIR: Valid patterns created based on the annotation guidelines or training set. Example files are provided in resource/valid_patterns.

We may train a new model with train.py.

python train.py -c ./config/train_rams.json

Training takes many arguments, all of which should be contained in a json file.
Here are two key arguments in the json file that should be taken note of.

  1. Location of the train / dev / test data files and the log file.
    "train_file": "<TRAIN_FILE_PATH>",
    "dev_file": "<DEV_FILE_PATH>",
    "test_file": "<TEST_FILE_PATH>",
    "log_path": "<OUTPUT_DIR>",
  1. Path of the valid patterns.
    "valid_pattern_path": "<VALID_PATTERN_DIR>",

The files in this path should define specifics of entity / relation / event extraction.
For instance, event_role.json will specify what arguments come with the Movement:Transport event.

  "Movement:Transport": [
    "Vehicle",
    "Artifact",
    "Agent",
    "Origin",
    "Destination"
  ],

Training in EAI toolkit

In the root eai-dsta directory, run

./send_jobs <NAME OF JOB> <TYPE OF JOB>

TYPE OF JOB enums: train, test_acepp

Evaluation

  • cd to the root directory of this package
  • Set the environment variable PYTHONPATH to the current directory. For example, if you unpack this package to ~/oneie_v0.4.5, run: export PYTHONPATH=~/oneie_v0.4.5
  • Example commandline to use OneIE: python predict.py -m best.role.mdl -i input -o output -c output_cs --format ltf
    • Arguments:
      • -m, --model_path: Path to the trained model.
      • -i, --input_dir: Path to the input directory. LTF format sample files can be found in the input directory.
      • -o, --output_dir: Path to the output directory (json format). Output files are in the JSON format. Sample files can be found in the output directory.
      • -c, --cs_dir: (optional) Path to the output directory (cs format). Sample files can be found in the output_cs directory.
      • -l, --log_path: (optional) Path to the log file. A sample file log.json can be found in output.
      • --gpu: (optional) Use GPU
      • -d, --device: (optional) GPU device index (for multi-GPU machines).
      • -b, --batch_size: (optional) Batch size. For a 16GB GPU, a batch size of 10~15 is a reasonable value.
      • --max_len: (optional) Max sentence length. Sentences longer than this value will be ignored. You may need to decrease batch_size if you set max_len to a larger number.
      • --beam_size: (optional) Beam set size of the decoder. Increasing this value may improve the results and make the decoding slower.
      • --lang: (optional) Model language.
      • --format: Input file format (txt or ltf).

Inference

We can then pass the preprocessed data into the pretrained model with predict.py.
Note that the data needs to be in the specified folder paths.

python predict.py -m models/english.role.v0.3.mdl -i test_train/data/input -o data/output --format json

Post-processing

To analyse errors from trained models:

python main_formatter.py 
   -test R11/test.oneie.json 
   -preds R11/predictions.oneie.json 
   --from_oneie 
   --filter_classes

python eventspecific.py 
   -preds T4/oneie_formatted_results.jsonl 
   -gold T4/test.json

Output Format

OneIE save results in JSON format. Each line is a JSON object for a sentence containing the following fields:

  • doc_id (string): Document ID
  • sent_id (string): Sentence ID
  • tokens (list): A list of tokens
  • token_ids (list): A list of token IDs (doc_id:start_offset-end_offset)
  • graph (object): Information graph predicted by the model
    • entities (list): A list of predicted entities. Each item in the list has exactly four values: start_token_index, end_token_index, entity_type, mention_type, score. For example, "[3, 5, "GPE", "NAM", 1.0]" means the index of the start token is 3, index of the end token is 4 (5 - 1), entity type is GPE, mention type is NAM, and local score is 1.0.
    • triggers (list): A list of predicted triggers. It is similar to entities, while each item has three values: start_token_index, end_token_index, event_type, score.
    • relations (list): A list of predicted relations. Each item in the list has three values: arg1_entity_index, arg2_entity_index, relation_type, score. In the following example, [1, 0, "ORG-AFF", 0.52] means there is a ORG-AFF relation between entity 1 ("leader") and entity 0 ("North Korean") with a local score of 0.52. The order of arg1 and arg2 can be ignored for "SOC-PER" as this relation is symmetric.
    • roles (list): A list of predicted argument roles. Each item has three values: trigger_index, entity_index, role, score. In the following example, [0, 2, "Attacker", 0.8] means entity 2 (Kim Jong Un) is the Attacker argument of event 0 ("detonate": Conflict:Attack), and the local score is 0.8.

Output example:

{"doc_id": "HC0003PYD", "sent_id": "HC0003PYD-16", "token_ids": ["HC0003PYD:2295-2296", "HC0003PYD:2298-2304", "HC0003PYD:2305-2305", "HC0003PYD:2307-2311", "HC0003PYD:2313-2318", "HC0003PYD:2320-2325", "HC0003PYD:2327-2329", "HC0003PYD:2331-2334", "HC0003PYD:2336-2337", "HC0003PYD:2339-2348", "HC0003PYD:2350-2351", "HC0003PYD:2353-2360", "HC0003PYD:2362-2362", "HC0003PYD:2364-2367", "HC0003PYD:2369-2376", "HC0003PYD:2378-2383", "HC0003PYD:2385-2386", "HC0003PYD:2388-2390", "HC0003PYD:2392-2397", "HC0003PYD:2399-2401", "HC0003PYD:2403-2408", "HC0003PYD:2410-2412", "HC0003PYD:2414-2415", "HC0003PYD:2417-2425", "HC0003PYD:2427-2428", "HC0003PYD:2430-2432", "HC0003PYD:2434-2437", "HC0003PYD:2439-2441", "HC0003PYD:2443-2447", "HC0003PYD:2449-2450", "HC0003PYD:2452-2454", "HC0003PYD:2456-2464", "HC0003PYD:2466-2472", "HC0003PYD:2474-2480", "HC0003PYD:2481-2481", "HC0003PYD:2483-2485", "HC0003PYD:2487-2491", "HC0003PYD:2493-2502", "HC0003PYD:2504-2509", "HC0003PYD:2511-2514", "HC0003PYD:2516-2523", "HC0003PYD:2524-2524"], "tokens": ["On", "Tuesday", ",", "North", "Korean", "leader", "Kim", "Jong", "Un", "threatened", "to", "detonate", "a", "more", "powerful", "H-bomb", "in", "the", "future", "and", "called", "for", "an", "expansion", "of", "the", "size", "and", "power", "of", "his", "country's", "nuclear", "arsenal", ",", "the", "state", "television", "agency", "KCNA", "reported", "."], "graph": {"entities": [[3, 5, "GPE", "NAM", 1.0], [5, 6, "PER", "NOM", 0.2], [6, 9, "PER", "NAM", 0.5060472888322202], [15, 16, "WEA", "NOM", 0.5332313915378754], [30, 31, "PER", "PRO", 1.0], [32, 33, "WEA", "NOM", 1.0], [33, 34, "WEA", "NOM", 0.5212696155645499], [36, 37, "GPE", "NOM", 0.4998288792916457], [38, 39, "ORG", "NOM", 1.0], [39, 40, "ORG", "NAM", 0.5294904130032032]], "triggers": [[11, 12, "Conflict:Attack", 1.0]], "relations": [[1, 0, "ORG-AFF", 1.0]], "roles": [[0, 2, "Attacker", 0.4597024700555278], [0, 3, "Instrument", 1.0]]}}
