New PHAGE encoder captures patent claim hierarchy for better analysis

Researchers have developed PHAGE, a novel graph encoder designed to better represent patent documents. Unlike previous methods that linearize claims and lose hierarchical information, PHAGE explicitly encodes the dependency structure between patent claims. It distinguishes between different types of claim relationships and integrates this topological information into a token-level attention mechanism. This approach significantly improves performance on patent classification, retrieval, and clustering tasks. AI

IMPACT Introduces a new method for encoding complex document structures, potentially improving AI's ability to analyze legal and technical documents.
