The file appears to be a specific dataset or supplement related to the MS-SL (Multi-Scale Semantic Linking) framework, often cited in computer vision and video analysis research. It is frequently associated with a 2022 ACM Multimedia (MM '22) paper titled "Multi-Scale Semantic Linking for Video-Text Retrieval" or similar works from the HuiGuanLab .
While the exact filename "SL_Hard.zip" is common in shared research directories (like Google Drive or Dropbox links found in GitHub repositories), it typically contains: SL_Hard_zip
