## Introduction
This is a large-scale dataset of Chu bamboo slip (CBS, Chinese: 楚简, chujian) script, an ancient Chinese script used during the Spring and Autumn period over 2,000 years ago. This dataset consists of two parts:
1. The main dataset where each example is an image and the corresponding text label. This part is contained in the `glyphs.zip` ZIP file.
2. A character detection dataset where each example is a bamboo slip and the corresponding bounding boxes of each CBS character. This part is contained in the `detection-data.zip` ZIP file.
3. A POS tagging dataset where each example is a sentence and POS annotations (using the BIO format). This part is contained under the `pos-tagging-data` directory.
This data is compiled to foster applications of NLP methods in the study of Chu bamboo slip script, and possibly other forms of ancient Chinese.
