Abstract

Vision-based document segmentation identifies one or more portions of semantic content of a document. The one or more portions are identified by identifying a plurality of visual blocks in the document, and detecting one or more separators between the visual blocks of the plurality of visual blocks. A content structure for the document is constructed based at least in part on the plurality of visual blocks and the one or more separators, and the content structure identifies the one or more portions of semantic content of the document. The content structure obtained using the vision-based document segmentation can optionally be used during document retrieval.

Description

technical field

[0001] The present invention relates to segmenting documents, and more particularly to vision-based document segmentation. Background technique

[0002] People have access to vast amounts of information. However, finding the specific information they need in any given situation can be quite difficult. For example, through the Internet, a vast amount of information is accessible to people in the form of web pages. The number of such web pages may be on the order of 1 million or more.

Processes and technologies were developed to allow users to search for information over the Internet, and are generally made available to...
