Dataset Summary

Collection3 is a Russian dataset for named entity recognition annotated with LOC (location), PER (person), and ORG (organization) tags. Dataset is based on collection Persons-1000 originally containing 1000 news documents labeled only with names of persons.

Additional labels were obtained using guidelines similar to MUC-7 with web-based tool Brat for collaborative text annotation.

Currently dataset contains 26K annotated named entities (11K Persons, 7K Locations and 8K Organizations).

Conversion to the IOB2 format and splitting into train, validation and test sets was done by DeepPavlov team.

Dataset Structure

Data Instances

An example of 'train' looks as follows.

{
    "id": "851",
    "ner_tags": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 3, 1, 2, 0, 0, 0],
    "tokens": ['Главный', 'архитектор', 'программного', 'обеспечения', '(', 'ПО', ')', 'американского', 'высокотехнологичного', 'гиганта', 'Microsoft', 'Рэй', 'Оззи', 'покидает', 'компанию', '.']
}

Data Fields

• id: a string feature.
• tokens: a list of string features.
• ner_tags: a list of classification labels (int). Full tagset with indices:

{'O': 0, 'B-PER': 1, 'I-PER': 2, 'B-ORG': 3, 'I-ORG': 4, 'B-LOC': 5, 'I-LOC': 6}
