Portuguese Handwriting 16th-19th c.

This dataset consists of images and transcribed pages of Portuguese manuscripts from the 16th to the 19th centuries, primarily derived from the court records of the Portuguese Inquisition. It is designed for training and evaluating Handwritten Text Recognition (HTR) models.

Dataset Description

Overview

This is a collection of images and corresponding ground truth transcriptions (text) of historical Portuguese handwritten documents. The majority of the documents are from the Portuguese Inquisition processes from Lisbon, Coimbra, and Évora.

The data is organized based on various training and validation sets created by the original researchers.

Data Collection and Processing

The documents were extracted from trial records (processos) by the members of the TraPrInq project (Transcrever os processos da Inquisição portuguesa, 1536-1821 | Transcribing the court records of the Portuguese Inquisition, 1536-1821).

Total Transcribed Pages (Ground Truth): 6,417
Time Period: 16th to 19th centuries
Original File Structure: The original Zenodo record divides the data into ten folders corresponding to training and validation sets.
- File Naming Conventions (Examples):
  - IL_number: Document extracted from a trial record by the Inquisition of Lisbon.
  - IC_: Document from the Inquisition of Coimbra.
  - IE_: Document from the Inquisition of Évora.
