PDF Document Segmentation for Webpage Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large PDF documents with extensive content hinder online browsing, downloading, and searching due to the need for complete document loading and downloading, resulting in poor user experience.
Innovation Solution
A method for segmenting PDF documents into multiple sub-documents based on original directory structures or lexical databases, allowing for incremental loading and navigation through jump and directory tags, enabling efficient online reviewing and downloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire PDF document is loaded for online browsing, then the complete document content is available for reading, but the loading time and user waiting period increase significantly
Solution Approach 1:
The patent divides a large PDF document into multiple smaller sub-documents based on the original directory structure. Each sub-document corresponds to a specific chapter or section, allowing the system to load and display only the relevant portion rather than the entire document, thus reducing loading time while maintaining content completeness.
2Ease of operation
If the entire PDF document is downloaded for offline reading, then the complete document is available for offline access, but the download size and network bandwidth consumption increase
Solution Approach 1:
The patent extracts and downloads only the necessary sub-documents based on user selection or predefined reading lists, rather than requiring the entire PDF document to be downloaded. This extraction approach maintains offline reading capability while significantly reducing the quantity of data that needs to be transferred.
3Measurement precision
If the entire PDF document is processed for searching, then comprehensive search results are obtained, but the processing time and computational resources increase
Solution Approach 1:
The patent segments the large PDF document into smaller sub-documents indexed by directory structure. When a search is performed, the system only processes the relevant sub-documents rather than the entire document, maintaining search completeness for the selected scope while dramatically improving search speed and reducing computational resource consumption.
4Ease of operation
If navigation within a large PDF document is implemented, then users can access specific sections, but the document structure complexity and navigation interface complexity increase
Solution Approach 1:
The patent utilizes the existing directory structure of the PDF document to create natural segmentation points for navigation. Each sub-document represents a logical section with its own context, allowing users to navigate between sections using simple directory-based interfaces rather than complex page-number or position-based navigation systems.

AI summary
The present invention relates to a method for segmenting a PDF document and a method for loading a PDF document in a webpage. The method for segmenting a PDF document includes: S101, inspecting whether a PDF document includes an original directory structure or not; S102, if yes, segmenting the PDF document into multiple PDF sub-documents according to the original directory structure; and S103, if no, segmenting the PDF document into multiple PDF sub-documents according to document contents of the PDF document and a lexical database corresponding to the PDF document. The present invention segments a PDF document into multiple PDF sub-documents to ease operations of for example online reviewing, downloading and searching of the PDF document, and improve a user's experience of use.
