Prune4Web: DOM Tree Pruning Programming for Web Agent

Location: Venue 8 - B03

Web automation uses intelligent agents to perform high-level tasks by mimicking human interactions with webpages. Despite recent advances in LLM-based web agents, efficiently navigating complex, real-world webpages remains challenging due to massive DOM structures. This talk will present Prune4Web, a paradigm that transforms DOM processing from LLM-based filtering to programmatic pruning. This approach eliminates the need for LLMs to process full DOMs, instead delegating traversal and scoring to lightweight, interpretable programs.
