# Dataset for the first Workshop on Information Extraction from Scientific Publications (WIESP/2022).

## Dataset Description

Datasets with text fragments from astrophysics papers, provided by the NASA Astrophysical Data System with manually tagged astronomical facilities and other entities of interest (e.g., celestial objects).
Datasets are in JSON Lines format (each line is a json dictionary).
The datasets are formatted similarly to the CONLL2003 format. Each token is associated with an NER tag. The tags follow the "B-" and "I-" convention from the IOB2 syntax

Each entry consists of a dictionary with the following keys:

• "unique_id": a unique identifier for this data sample. Must be included in the predictions.
• "tokens": the list of tokens (strings) that form the text of this sample. Must be included in the predictions.
• "ner_tags": the list of NER tags (in IOB2 format)

The following keys are not strictly needed by the participants:

• "ner_ids": the pre-computed list of ids corresponding ner_tags, as given by the dictionary in ner_tags.json
• "label_studio_id", "section", "bibcode": references for internal NASA/ADS use.

## Instructions for Workshop participants:

(assuming ./WIESP2022-NER-DEV.jsonl is in the current directory, change as needed)

• python (as list of dictionaries):
import json
with open("./WIESP2022-NER-DEV.jsonl", 'r') as f:
wiesp_dev_json = [json.loads(l) for l in list(f)]

• into Huggingface (as a Huggingface Dataset):
from datasets import Dataset
wiesp_dev_from_json = Dataset.from_json(path_or_paths="./WIESP2022-NER-DEV.jsonl")

How to compute your scores on the training data:

1. format your predictions as a list of dictionaries, each with the same "unique_id" and "tokens" keys from the dataset, as well as the list of predicted NER tags under the "pred_ner_tags" key (see WIESP2022-NER-DEV-sample-predictions.jsonl for an example).
2. pass the references and predictions datasets to the compute_MCC() and compute_seqeval() functions (from the .py files with the same names).

Requirement to run the scoring scripts:
NumPy
scikit-learn
seqeval

To get scores on the validation data, zip your predictions file (a single .jsonl' file formatted following the same instructions as above) and upload the .zip file to the Codalabs competition.
