pretty_name: Split ICDAR2017 dataset
---
This dataset is a filtered version of the *ICDAR2017* Competition on Handwritten Text Recognition, focusing on monograph texts written between 1800 and 1900. It consists of a total of **957 documents**, divided into training, validation, and testing sets, and is designed for post-correction of OCR (Optical Character Recognition) text.
- **Total Documents**: 957
- **Training Set**: 765
- **Validation Set**: 95
- **Test Set**: 97
## Purpose
The dataset aims to improve the accuracy of digitized texts by providing a reliable Ground Truth for comparison and correction, specifically addressing the challenges of French text of 19th century.
## Structure
The dataset is organized as follows:
```plaintext
dataset/
β”œβ”€β”€ train/
β”‚ β”œβ”€β”€ file1.txt
β”‚ β”œβ”€β”€ file2.txt
β”‚ └── ...
β”œβ”€β”€ dev/
β”‚ β”œβ”€β”€ file1.txt
β”‚ β”œβ”€β”€ file2.txt
β”‚ └── ...
β”œβ”€β”€ test/
β”‚ β”œβ”€β”€ file1.txt
β”‚ β”œβ”€β”€ file2.txt
β”‚ └── ...
└── metadata.csv # This file contains metadata for each txt file
```
- **Content** [#.txt]
- **1st line**: "[OCR_toInput] " => Raw OCRed text to be denoised.
- **2nd line**: "[OCR_aligned] " => Aligned OCRed text.
- **3rd line**: "[GS_aligned] " => Aligned Gold Standard.
The alignment was made at the character level using "@" symbols. "#" symbols correspond to the absence of GS either related to alignment uncertainities or related to unreadable characters in the source document.
For a better view of the alignment, make sure to disable the "word wrap" option in your text editor.
