Load Dataset

You can read in WEC-Eng files as follows (using the huggingface_hub library):

from huggingface_hub import hf_hub_url, cached_download
import json
REPO_ID = "datasets/Intel/WEC-Eng"
splits_files = ["Dev_Event_gold_mentions_validated.json",
                "Test_Event_gold_mentions_validated.json",
                "Train_Event_gold_mentions.json"]
wec_eng = list()
for split_file in splits_files:
    wec_eng.append(json.load(open(cached_download(
        hf_hub_url(REPO_ID, split_file)), "r")))
