| ### Dataset Summary | |
| LeNER-Br is a Portuguese language dataset for named entity recognition | |
| applied to legal documents. LeNER-Br consists entirely of manually annotated | |
| legislation and legal cases texts and contains tags for persons, locations, | |
| time entities, organizations, legislation and legal cases. | |
| To compose the dataset, 66 legal documents from several Brazilian Courts were | |
| collected. Courts of superior and state levels were considered, such as Supremo | |
| Tribunal Federal, Superior Tribunal de Justiça, Tribunal de Justiça de Minas | |
| Gerais and Tribunal de Contas da União. In addition, four legislation documents | |
| were collected, such as "Lei Maria da Penha", giving a total of 70 documents | |
| ### Supported Tasks and Leaderboards | |
| [More Information Needed] | |
| ### Languages | |
| The language supported is Portuguese. | |
| ## Dataset Structure | |
| ### Data Instances | |
| An example from the dataset looks as follows: | |
| ``` | |
| { | |
| "id": "0", | |
| "ner_tags": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 2, 0, 0, 0], | |
| "tokens": [ | |
| "EMENTA", ":", "APELAÇÃO", "CÍVEL", "-", "AÇÃO", "DE", "INDENIZAÇÃO", "POR", "DANOS", "MORAIS", "-", "PRELIMINAR", "-", "ARGUIDA", "PELO", "MINISTÉRIO", "PÚBLICO", "EM", "GRAU", "RECURSAL"] | |
| } | |
| ``` | |
| ### Data Fields | |
| - `id`: id of the sample | |
| - `tokens`: the tokens of the example text | |
| - `ner_tags`: the NER tags of each token | |
| The NER tags correspond to this list: | |
| ``` | |
| "O", "B-ORGANIZACAO", "I-ORGANIZACAO", "B-PESSOA", "I-PESSOA", "B-TEMPO", "I-TEMPO", "B-LOCAL", "I-LOCAL", "B-LEGISLACAO", "I-LEGISLACAO", "B-JURISPRUDENCIA", "I-JURISPRUDENCIA" | |
| ``` | |
| The NER tags have the same format as in the CoNLL shared task: a B denotes the first item of a phrase and an I any non-initial word. | |
| ### Data Splits | |
| The data is split into train, validation and test set. The split sizes are as follow: | |
| | Train | Val | Test | | |
| | ------ | ----- | ---- | | |
| | 7828 | 1177 | 1390 | | |
