MAP：跨抽象层级比较计算机使用行为的分层语义表示与标注流程

arXiv:2610.26703v1 Announce Type: new Abstract: Interaction traces record how people and agents use computers, and comparing them can reveal usability barriers, differences in expertise, and human--agent similarity. Yet traces are recorded as low-level, interface-specific actions, making comparisons difficult across tasks, interfaces, and input modalities. Existing approaches either compare these actions directly, reduce traces to aggregate outcomes, or summarize them at higher-level goals, obscuring where behavior differs. We present MAP (Multi-level Action Parsing), a hierarchical semantic representation and annotation pipeline that maps traces into a common vocabulary across linked levels of abstraction. MAP compares traces by sequence, recurring patterns, and effort, localizing differences by type and abstraction level. A technical evaluation across three computer use datasets shows high agreement with manual annotations and broad coverage of behavior. Applying MAP shows that sighted and blind users increasingly converge at higher levels despite navigation differences, while agents omit corrective, help-seeking, and recovery behaviors present in human traces.
