Auto-Linking Multimedia to E-Book Sections via Concept Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic documents, such as e-books, lack integrated multimedia content items, making it time-consuming for users to determine relevant content and optimal placement within the document, particularly in educational contexts where diverse formats enhance comprehension.
Innovation Solution
A system that analyzes document sections and content items by determining concept phrases from text and user queries, associating content items with the document sections that best cover these phrases, and linking or embedding them for optimal presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If content items are manually selected and placed in electronic documents, then relevance and appropriateness can be ensured, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The system enables automatic association of content items with document sections through self-service mechanisms. The processor automatically analyzes document sections, generates concept phrases, retrieves relevant content items from a database, and associates them without requiring manual user intervention for each pairing decision.
Solution Approach 2:
The manual mechanical process of reading and evaluating content items is replaced with an automated computational system. The processor substitutes human cognitive effort by automatically comparing concept phrases from document sections with concept phrases from content items using algorithmic matching and scoring mechanisms.
2Adaptability or versatility
If multiple content items are associated with each document section, then user engagement and comprehension improve, but the complexity of managing and organizing content increases
Solution Approach 1:
The system manages complexity by changing parameters such as concept phrase matching thresholds, scoring weights, and association criteria. These parameter adjustments allow the system to control the number and relevance of associated content items while maintaining manageable organizational structures through configurable matching parameters.
3Productivity
If automated systems are used to associate content items with document sections, then time efficiency improves, but the precision of matching may decrease
Solution Approach 1:
The system incorporates feedback mechanisms through scoring and ranking processes. The processor calculates association scores based on concept phrase matching, provides ranked results, and allows for iterative refinement. This feedback loop enables the automated system to maintain high matching precision by evaluating and selecting the best associations based on calculated scores.
Solution Approach 2:
The system performs preliminary actions by pre-processing document sections to extract concept phrases before content item association. This preliminary concept phrase generation and storage enables faster, more accurate matching during the actual association process, improving both speed and precision through advance preparation.

AI summary
A document such as a book or textbook includes multiple sections such as chapters. Concept phrases are determined for each of the sections based on the text of each section. A set of content items such as videos is received, and each content item is associated with one or more queries that were submitted by users who were provided the content item in a set of search results. These queries are processed to determine concept phrases that are associated with the content items. The content items and their associated concept phrases are compared with the concept phrases associated with the sections to determine, for some or all of the content items, a minimum subset of the sections whose associated concept phrases cover most of the concept phrases that are associated with the content item. The content items are inserted or linked with the sections in their corresponding minimum subsets.
