Automatic Footnote Generation via Semantic Similarity Ranking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Readers of online documents face difficulties in verifying statements of fact due to the lack of identified reliable sources, as authors often fail to provide footnotes or links to supporting information, making it cumbersome to navigate and find relevant passages.
Innovation Solution
An automatic footnote generation method that assesses the semantic similarity between document passages and external documents, generating a ranking score to determine if a footnote link should be added to the document, linking to the most relevant external passage if the score exceeds a threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authors manually add footnotes to identify sources, then reliability of statements is improved, but ease of operation and time consumption are worsened
Solution Approach 1:
The system enables automatic footnote generation where the computing device autonomously identifies statements in the document, searches for supporting external documents, generates ranking scores, and creates footnote links without human intervention. This self-service approach resolves the contradiction by eliminating the manual effort required while maintaining reliability through automated semantic similarity matching and ranking processes.
Solution Approach 2:
The system performs preliminary actions by pre-processing the document to identify statements that require footnotes, pre-searching external documents for relevant passages, and pre-calculating ranking scores before the user even requests footnotes. This advance preparation eliminates the need for manual footnote creation while ensuring reliability through thorough preliminary verification of source匹配.
2Measurement precision
If readers manually search for external sources to verify statements, then verification accuracy is improved, but loss of time is worsened
Solution Approach 1:
The system introduces an intermediary automated footnote generation process that mediates between the reader and external sources. Instead of readers directly searching through multiple external documents, the system acts as an intermediary that automatically retrieves, ranks, and presents the most relevant external passages with footnote links, maintaining verification accuracy while eliminating the time-consuming manual search process.
Solution Approach 2:
The system replaces the mechanical manual search process with an automated computational system that uses semantic similarity algorithms and ranking scores to identify and link relevant external sources. This substitution maintains the accuracy of source verification while dramatically reducing the time required by replacing human manual searching with efficient automated text processing and matching algorithms.
3Ease of operation
If no footnotes are provided in documents, then ease of operation is improved, but reliability is worsened
Solution Approach 1:
The system applies local quality by selectively adding footnotes only to specific statements in the document that require verification, rather than uniformly adding footnotes throughout or leaving the document completely without footnotes. This localized approach maintains the simplicity of reading for statements that don't need verification while providing reliability enhancement where needed, thus resolving the contradiction between ease of operation and reliability.
Data Source
AI summary
A method includes accessing a document and generating a ranking score for each of a plurality of passages from external documents. The ranking score is based at least on a degree of semantic similarity of each passage with respect to a portion of the document. The method also includes modifying the document to include a footnote link for the portion of the document, the footnote link including a link to the external document having the highest ranked passage therein, if the ranking score of the highest ranked passage with respect to the portion of the document exceeds a threshold value. The document is not modified to include the footnote link for the portion of the document if the ranking score of the highest ranked passage with respect to the portion of the document does not exceed a threshold value.
