The poster search engine is an archive of over 23,000 artworks and posters produced during Hong Kong’s 2019-2020 anti-extradition law movement.

Methodology and sourcing – click to view

The Poster Search Engine allows for text inside the movement posters to be searchable. In total, 23,366 posters have been collected from two major movement publicity Telegram channels: 777文宣傳播稿件大合集 and 反送中文宣谷 covering the movement up until January 23, 2020 and January 18, 2020 respectively. The text inside the posters was OCR-extracted by Google Docs, tokenised, and indexed. OCR errors were manually corrected by a team of Cantonese-speaking human editors who understand the context. Key movement-related terms (listed in the glossary) were added below each poster as hashtags to facilitate user navigation from one poster to a larger set of related posters.
