• 2024-3-15: It's thrilling to share that Azure AI Document Intelligence has introduced support for Hierarchical Document Structure Analysis (HDSA), as detailed in our recently published paper, "Detect-Order-Construct: A Tree Construction based Approach for Hierarchical Document Structure Analysis." This advancement opens up new possibilities for analyzing complex document structures more effectively. For more details on this breakthrough, check out our publication on arXiv and the official announcement.

• 2024-3-4: We released the source code of our solution for the Language-Enhanced Image New Category Discovery at the 2nd The Guangdong–Hong Kong–Macao Greater Bay Area International Algorithm and Programming Contest (Visual Prompt Tuning Challenge @ CVPR 2023 HIT Workshop (2023)).

• 2024-2-1: We submitted our new progress on Document Layout Analysis, named DLAFormer: A End-to-End Transformer for Document Layout Analysis, to ICDAR 2024.

• 2024-1-18: We released a unified label space approach for Visual Information Extraction, named UniVIE: A Unified Label Space Approach to Visual Information Extraction from Form-like Documents! In this work, we present a new perspective, reframing VIE as a relation prediction problem and unifying labels of different tasks into a single label space. This unified approach allows for the definition of various relation types and effectively tackles hierarchical relationships in form-like documents.
