HK Web Text Corpus (MySQL Dump, raw version)

Overview

⚠ This dataset provides the MySQL dump file which contains a large-scale raw text corpus collected from various Hong Kong public web sources, primarily focused on Hong Kong Cantonese and Traditional Chinese language usage.

It was used for generating Hong Kong Content Corpus, which was then used in the experiments reported in https://doi.org/10.1145/3744341 to study the effect of diglossia on Hong Kong language modeling.

This MySQL database is intended for archival and reproducibility purposes, and may include noise, duplication, HTML markup, crawler residues, and records that were subsequently cleaned/filtered in the derived corpus release.

This dataset is also available at Zenodo as splited archive: https://doi.org/10.5281/zenodo.16875235

Intended Uses

Pretraining or fine-tuning AI language models
Linguistic and sociolinguistic analysis
Text mining research

NOTE: HKNSL became effective since 2020-6-30, which can create bias on user content created afterwards. Those portion of data should be used with caution.
