Semantic Partitioning

A technique for automatically dividing a web page into semantically meaningful segments or blocks based on the structural and visual properties of its HTML content. Semantic partitioning analyzes the DOM tree to group related elements using spatial locality (items close together on screen), sequential patterns (recurring tag structures), and content similarity. The resulting partitions are then labeled with semantic concepts from a domain ontology, enabling assistive technologies to present web content in meaningful logical chunks rather than as a flat sequence of HTML elements. This approach is particularly valuable for screen reader users who benefit from understanding the logical organization of a page.
