Found at the Hong Kong Free Press: Hong Kong Protest Movement Data Archive: Poster Search Engine. From the “Methodology and sourcing” section: “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.”
