Adaptive Presentation Document System Using Grammar-Based Content Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia presentation systems are inflexible, as they require all conference participants to receive the same content, failing to account for varying participant interests, technical knowledge, and security authorizations, leading to a need for personalized content delivery.
Innovation Solution
The development of a presentation document system that utilizes a content-specific presentation grammar and structured documents, where structural elements are marked with identifiers, allowing for personalized content filtering based on user attributes such as company, department, technical knowledge, and security authorization, enabling different versions of content to be presented to individual users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single unified presentation is delivered to all conference participants, then the system maintains simplicity in content management, but the system fails to account for varying participant interests, technical knowledge, and security authorizations, resulting in reduced presentation effectiveness
Solution Approach 1:
The presentation document is segmented into multiple versions of the same content (e.g., first version, second version, third version) stored within a single document. Each version is associated with specific user attributes through grammar elements, allowing the system to deliver appropriate content versions to different users without creating separate presentation files for each user or user group.
Solution Approach 2:
A single presentation document structure serves multiple functions by incorporating multiple content versions and grammar elements that respond to different user attributes. The grammar system universally handles various user classifications (technical knowledge level, security authorization, department membership) and automatically selects appropriate content versions, making one document adaptable to diverse user needs.
2Adaptability or versatility
If separate presentations are created for each audience segment, then content can be tailored to specific user groups, but the system requires substantial manual effort and time to create and maintain multiple separate presentation files
Solution Approach 1:
Instead of creating separate presentation files for each audience segment, the system segments content within a single presentation document using version numbers and associates them with user attributes through grammar elements. This allows personalized content delivery without the time-consuming process of creating and managing multiple separate presentation files.
Solution Approach 2:
The presentation system automatically selects and delivers appropriate content versions to users based on their attributes (technical knowledge, security authorization, department membership) without requiring manual intervention. The grammar elements and user attribute matching enable the system to self-service the content selection process, eliminating the need for presenters to manually configure different presentations for different users.
3Ease of operation
If content is reduced to the lowest common denominator for all participants, then the presentation can be understood by all users, but specialized content needed by certain user groups (e.g., researchers needing technical details) cannot be effectively delivered
Solution Approach 1:
The presentation document contains multiple segmented versions of content (first version, second version, third version) with varying levels of detail and technical depth. Grammar elements associate each version with specific user attributes, allowing users to receive appropriately detailed content without forcing all users to consume oversimplified material. Researchers receive technical versions while marketers receive simplified versions.
Solution Approach 2:
Different portions of the presentation document have different qualities and levels of detail tailored to specific user groups. The grammar system ensures that each user receives content with appropriate local quality (technical depth, security classification) based on their attributes, rather than applying a uniform quality level to all content.
4Adaptability or versatility
If multiple versions of content are stored in a single presentation document with grammar elements, then the system achieves flexible content delivery based on user attributes, but the complexity of the presentation document structure increases
Solution Approach 1:
The system extracts the complexity of content versioning and user attribute matching into a separate grammar layer. The grammar elements (with attributes like technical knowledge level, security authorization, department membership) are extracted from the content itself and stored as metadata associations. This separation allows the content to remain relatively simple while the grammar layer handles the complexity of adaptive content delivery.

AI summary
Creating a presentation document includes creating, in dependence upon an original document, a structured document comprising one or more structural elements and creating a presentation grammar for the structured document, wherein the presentation grammar for the structured document includes grammar elements each of which includes a structural element identifier for at least one structural element of the structured document.
