Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional built-in dictionaries in reading apps provide inaccurate, contextually inappropriate, and overly complex word definitions, disrupting the reading flow and hindering comprehension for users with limited language proficiency.
Innovation Solution
An AI-driven definition generation system that integrates programmatic control and guided AI to provide contextually relevant word definitions tailored to the user's reading level and passage context, using user profiles and natural language processing to generate personalized and context-specific definitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional built-in dictionaries are used to provide word definitions, then readers can look up word meanings, but the definitions are too advanced and complex for readers with limited language proficiency, creating a barrier to understanding
Solution Approach 1:
The system dynamically adjusts the complexity parameter of definitions based on the reader's identified reading level. By changing the linguistic complexity parameter to match the reader's ability, the system makes definitions accessible while maintaining accuracy. The AI engine generates definitions tailored to specific reading levels (e.g., elementary, middle school, high school) rather than using a fixed complex definition for all users.
Solution Approach 2:
The system automatically determines the reader's reading level and selects appropriate definitions without requiring manual intervention. The AI engine self-adjusts the definition complexity based on the reader's profile and the context, eliminating the need for users to manually select definition difficulty levels or provide additional input about their reading ability.
2Loss of information
If sequential word lookup is implemented to provide definitions, then readers can access word meanings, but the reading flow is disrupted and focus is lost
Solution Approach 1:
The system pre-processes the text to identify and highlight unfamiliar words before the reader needs to look them up. By marking unknown words in advance and providing instant definitions upon selection, the system prevents disruption to the reading flow. The AI engine analyzes the context and prepares appropriate definitions before the reader encounters the word, enabling seamless learning without breaking concentration.
3Productivity
If lemmatization and stemming techniques are used to identify root words, then dictionary searches can be performed, but incorrect definitions are generated (e.g., lemmatizing 'outdoor' yields 'door'), hindering the learning process
Solution Approach 1:
The system introduces an AI engine as an intermediary between the word processing stage and the definition generation stage. Instead of directly using lemmatization and stemming results to query dictionaries, the AI engine acts as a mediator that understands contextual nuances and generates appropriate definitions. This intermediary layer filters out incorrect definitions and selects the most contextually relevant ones, preventing errors like defining 'outdoor' as 'door'.
Solution Approach 2:
The system replaces traditional mechanical word processing techniques (lemmatization, stemming) with AI-based natural language processing. Instead of relying on rule-based mechanical transformations that produce incorrect results, the AI engine uses contextual analysis and semantic understanding to generate accurate definitions. This substitution of mechanical processes with intelligent processing eliminates the errors inherent in traditional methods.
4Adaptability or versatility
If static dictionary modules are provided for different age groups, then reading level appropriateness is addressed, but the system does not adapt dynamically to individual user comprehension skills or textual context
Solution Approach 1:
The system transitions from static age-based dictionary modules to a dynamic AI-driven definition generation system. The AI engine continuously adapts to individual users by analyzing their reading level, preferences, and performance in real-time. The system dynamically adjusts definition complexity based on the specific textual context and user profile, creating a flexible, personalized learning experience that evolves with each user interaction rather than relying on fixed pre-defined categories.
Data Source
AI summary
AI-driven definition generation system and method disclosed herein guides an artificial intelligence (AI) engine to provide contextually relevant definitions of words given in a passage. The AI-driven definition generation system includes an online learning platform such that a user can select any word given in a passage on the online learning platform to instantly receive a contextually relevant definition of the selected word. The definition is generated as per the reading level of the user and the context of the surrounding passage. The AI-driven definition generation system achieves this by integrating user profile information, analyzing the surrounding text of selected words, and using an AI engine guided by a content generation system.
