BIS Speeches NER dataset

BIS Speeches NER dataset is a large-scale annotated dataset of central bank speeches (1996–2024) curated for Named Entity Recognition (NER). It was developed to support the fine-tuning of Central Bank BERT and related models for extracting structured metadata from central bank communication.

Models Trained on This Dataset

• Central Bank NER – fine-tuned NER model for AUTHOR, POSITION, AFFILIATION.

Dataset Schema

Each row corresponds to a single central bank speech record with the following fields:

Column	Type	Description
url	string	Direct BIS link to the PDF of the speech.
title	string	Short title of the speech as listed in the BIS archive.
description	string	Concise description of the speech, typically including the speaker’s name, role, and affiliation.
date	datetime	Date of the speech.
text	string	Full text of the speech.
processed_text	list[string]	Pre-processed sentence-level text (tokenized, normalized, lowercased).
author	string	Name of the speech author or speaker.
affiliation	string	Institution or central bank associated with the speaker (e.g., People’s Bank of China, European Central Bank).
position	string	Official role or title of the speaker (e.g., Governor, Deputy Governor).
country	string	Country corresponding to the affiliation.

Source

• Original data: BIS database of central bank speeches (1996–2024).
• Corpus size: 17,648 speeches annotated for training, with 1,961 held out for validation.
• Language: English.

Annotation Process

1. A small subset of speech descriptions was manually annotated for entity spans (AUTHOR, POSITION, AFFILIATION).
2. This seed set was used to train an initial NER model.
3. The model was applied to the full BIS corpus (1996–2024) to generate preliminary labels.
4. All annotations were manually reviewed and corrected, ensuring full coverage and consistency.

This hybrid manual + machine-assisted annotation approach enabled efficient, large-scale dataset creation while maintaining high quality.

Example

{
  "tokens": ["speech", "by", "mr", "yi", "gang", ",", "governor", "of", "the", "people", "'s", "bank", "of", "china"],
  "ner_tags": ["O", "O", "B-AUTHOR", "I-AUTHOR", "I-AUTHOR", "O",
               "B-POSITION", "O", "O", "B-AFFILIATION", "I-AFFILIATION",
               "I-AFFILIATION", "I-AFFILIATION", "I-AFFILIATION"]
}

Intended Uses

• Training NER models for central banking and financial policy analysis.
• Benchmarking domain-specific NER tasks.
• Research on monetary policy communication and speaker metadata extraction.
