title: ProfNER corpus: gold standard annotations for profession detection in Spanish COVID-19 tweets

description: <strong>THERE IS A NEWER VERSION (1.3) THAT INCORPORATES THE UNANNOTATED TEST AND BACKGROUND FILES </strong> Gold Standard annotations for SMM4H-Spanish shared task. SMM4H 2021 accepted at NAACL (scheduled in Mexico City in June) https://2021.naacl.org/. <br> <strong>Introduction:</strong><br> The entire corpus contains 10,000 annotated tweets. It has been split into training, validation and test (60-20-20). The current version contains the training and development set of the shared task with Gold Standard annotations.<br> In future versions of the dataset, test and background sets will be released. For the subtask-1 (classification), annotations are distributed in a tab-separated file (TSV). The TSV format follows the format employed in SMM4H 2019 Task 2:<br> tweet_id class<br> <br> For the subtask-2 (Named Entity Recognition, profession detection), annotations are distributed in 2 formats: Brat standoff and TSV. See Brat webpage for more information about Brat standoff format (https://brat.nlplab.org/standoff.html). The TSV format follows the format employed in SMM4H 2019 Task 2:<br> tweet_id begin end type extraction In addition, we provide a tokenized version of the dataset, for participant's convenience. It follows the BIO format (similar to CONLL). The files were generated with the brat_to_conll.py script (included), which employs the es_core_news_sm-2.3.1 Spacy model for tokenization. <br> <strong>Zip structure:</strong> txt-files: folder with text files. One text file per tweet. One sub-directory per corpus split (train and valid). txt-files-english: folder with text files Machine Translated to English. subtask-1: One file per corpus split (train.tsv and valid.tsv). subtask-2: brat: folder with annotations in Brat format. One sub-directory per corpus split (train and valid). tsv: folder with annotations in TSV. One file per corpus split (train and valid). BIO: folder with corpus in BIO tagging. One file per corpus split (train and valid). <strong>Annotation quality:</strong> We have performed a <strong>consistency analysis</strong> of the corpus. 10% of the documents have been annotated by an internal annotator as well as by the linguist experts following the same annotation guideliens. The preliminary Inter-Annotator Agreement (pairwise agreement) is 0.919. <br> <strong>Important shared task information:<br> SYSTEM PREDICTIONS MUST FOLLOW THE TSV FORMAT.</strong> And systems will only be evaluated for the PROFESION and SITUACION_LABORAL predictions (despite the Gold Standard contains 2 extra entity classes). For more information about the evaluation scenario, see the Codalab link, or the evaluation webpage.
