Document Summary via Page Importance Ranking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inefficiencies in browsing and locating important content within large documents, as they need to spend significant time reviewing multiple pages to grasp the main content, especially in scenarios like search results where numerous documents are returned.
Innovation Solution
A method is proposed to generate a summary of a document by extracting feature information from its pages, determining the importance of each page based on this information, and selecting a predetermined number of key pages to represent the document's main content, thereby reducing the time needed to understand the document's essence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all pages of a document are provided to users, then complete information is available, but users spend excessive time browsing through numerous pages to locate main content
Solution Approach 1:
The patent extracts and presents only the most important pages from a document as a summary, separating the essential content from the less important pages. This allows users to quickly access main content without browsing through all pages, while the complete document remains available if needed.
Solution Approach 2:
The system performs preliminary analysis of the document to identify and rank important pages before user interaction. By pre-processing the document and determining page importance in advance, the system prepares a curated summary that users can access immediately without time-consuming browsing.
2Loss of time
If a summary of a document is generated by selecting only key pages, then browsing time is reduced, but there is a risk of losing some information
Solution Approach 1:
The patent changes the parameter of page selection from random or sequential to importance-based ranking. By introducing an importance metric that evaluates each page's contribution to the main content, the system selects pages that maximize information value while minimizing the number of pages users need to browse.
3Reliability
If users manually review all pages to understand main content, then complete comprehension is achieved, but productivity is reduced due to time consumption
Solution Approach 1:
The patent introduces an automated summary generation system as an intermediary between the complete document and the user. This intermediary processes the document, identifies important pages, and presents them in a curated summary, allowing users to achieve reliable comprehension of main content without manually reviewing all pages.

AI summary
According to implementations of the subject matter described herein, there is provided a solution for generating a summary of a document. In this solution, feature information of pages comprised in a document is extracted, which characterizes at least one type of content contained in each page. Respective importance of the pages is determined at least based on the extracted feature information. A summary of the document is generated for the document by selecting a predetermined number of pages less than the number of the pages based on the respective importance. Through the solution, instead of providing all the pages, pages containing important content may be determined automatically to serve as the summary of the document. This summary allows the user to learn quickly main content of the document, shorten the time consumed in browsing all documents and/or facilitate location of a document of interest as soon as possible.
