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. In addition, it contains the unannotated test and background sets will be released. Participants must submit predictions for the files under the directory "test-background-txt-files" For subtask-1 (classification), annotations are distributed in a tab-separated file (TSV). The TSV format follows the format employed in SMM4H 2019 Task 2: tweet_id    class   For subtask-2 (Named Entity Recognition, profession detection), annotations are distributed in 2 formats: Brat standoff and TSV. See the Brat webpage for more information about the Brat standoff format (https://brat.nlplab.org/standoff.html). The TSV format follows the format employed in SMM4H 2019 Task 2: 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. Zip structure: subtask-1: files of tweet classification subtask. Content: One TSV file per corpus split (train and valid). train-valid-txt-files: folder with training and validation text files. One text file per tweet. One sub-directory per corpus split (train and valid). train-valid-txt-files-english: folder with training and validation text files Machine Translated to English. test-background-txt-files: folder with the test and background text files. You must make your predictions for these files and upload them to CodaLab. subtask-2: files of Named Entity Recognition subtask. Content: 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) train-valid-txt-files: folder with training and validation text files. One text file per tweet. One sub-directory per corpus split (train and valid) train-valid-txt-files-english: folder with training and validation text files Machine Translated to English. test-background-txt-files: folder with the test and background text files. You must make your predictions for these files and upload them to CodaLab. Annotation quality: We have performed a consistency analysis 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.   For further information, please visit https://temu.bsc.es/smm4h-spanish/ or email us at [email protected]   Do not share the data with other individuals/teams without permission from the task organizer.
