AI-Powered Educational Content Analysis
QuesGenie: Automating Multimodal Question Generation
The research introduces QuesGenie, an intelligent system designed to address the time-consuming task of creating educational assessments. By processing diverse content formats like PDFs, presentations, and audio, it automatically generates a variety of question types, reducing educator workload and providing students with tailored practice materials.
Enterprise Impact: From Content to Curriculum
For corporate training, EdTech platforms, and educational institutions, this technology transforms static content into interactive learning experiences. It enables rapid curriculum development, personalized learning paths, and scalable knowledge assessment, directly improving learner engagement and knowledge retention.

Unified Content Processing Engine
The system's foundation is its ability to handle multiple input formats. It uses specialized parsers for PowerPoint (PPTX) and PDF documents to extract both text and images, preserving their context (e.g., slide or page number). For audio content, it integrates OpenAI's Whisper model for robust transcription, converting spoken lectures into text chunks with timestamps. This multimodal capability ensures that no information is lost, regardless of the source format.
Advanced Text-to-Text Generation
For generating questions from text, QuesGenie employs the T5 (Text-to-Text Transfer Transformer) model. It utilizes multiple fine-tuned versions of T5 to produce different question types. Factual questions are generated using a model trained on the SQuAD dataset, multiple-choice distractors are created with a model trained on RACE, and True/False questions are handled by a model fine-tuned on BoolQ. This specialized approach ensures high-quality output for each question format.
Intelligent Visual Question Generation
QuesGenie uses a sophisticated two-step pipeline for images. First, a custom-trained ResNet-50 classifier (DiaClass) determines if an image is an educational diagram with 99% accuracy. This prevents irrelevant questions from decorative images. Second, confirmed diagrams are passed to ChartGemma, a powerful vision-language model, which analyzes the visual information and generates contextually relevant questions and answers about the chart or diagram.
Continuous Improvement Feedback Loop
A key feature is the system's ability to learn and improve. It incorporates a Reinforcement Learning from Human Feedback (RLHF) pipeline. User ratings on generated questions are used to train a reward model (DistillRoBERTa). This reward model then guides the T5 question generation model using Proximal Policy Optimization (PPO) to produce questions that better align with human preferences over time, making the system progressively smarter.

Case Study: Iterative Improvement via Reinforcement Learning
The system implements a feedback loop using Proximal Policy Optimization (PPO), a state-of-the-art reinforcement learning algorithm. Even without extensive human feedback, leveraging a pre-trained reward model resulted in a measurable improvement in question structure and relevance, as validated by BLEU and ROUGE scores. This demonstrates a production-ready pipeline for continuous model enhancement, allowing the system to adapt and align with user preferences over time, ensuring long-term value and accuracy.

Your Path to Automated Curriculum Development
Phase 1: Content Audit & Integration
We connect the QuesGenie engine to your existing content repositories—PDFs, slide decks, internal wikis, and video libraries—to create a unified knowledge source.
Phase 2: Baseline Model Deployment
Our system performs an initial pass on your content, generating a comprehensive bank of questions across all supported formats, providing immediate value and a baseline for quality assessment.
Phase 3: Feedback Loop Activation
We deploy a simple interface for your Subject Matter Experts (SMEs) to rate the generated questions. This crucial feedback becomes the fuel for model optimization.
Phase 4: Continuous Optimization & Scaling
The reinforcement learning pipeline uses the collected feedback to continuously fine-tune the AI models, improving question quality and relevance as the system is used more widely across your organization.
