Core Views

This project is a containerized test paper generation system based on LangGraph agent orchestration, Qwen3 large model, BGE-M3 embedding, and Qdrant vector search, equipped with a Next.js analytics dashboard. It addresses the pain points of traditional test paper creation, such as time-consuming processes, reliance on manual experience, and difficulty in ensuring consistent quality and difficulty. It demonstrates the application potential of AI technology in the education field and provides a reference technical architecture example for the educational technology industry.

In the education field, test paper creation has always been a time-consuming task requiring high professional knowledge. The traditional process relies on teachers' manual experience, which is inefficient and makes it difficult to ensure the consistency of question quality and difficulty. With the development of AI technology, it has become possible to automate this process using large language models and agent systems.

The Question-Paper-Generation-System combines an advanced AI technology stack to build a complete intelligent test paper generation platform. It not only demonstrates the application potential of modern AI in education but also provides a technical architecture example for the EdTech industry.

LangGraph Agent Orchestration Layer

The LangGraph framework is used to coordinate multiple agents: content understanding (analyzing outline knowledge points), question generation, difficulty calibration, quality review, and layout optimization. Multiple agents focus on subtasks and collaborate to complete the process through graph-structured execution paths.

Qwen3 Large Language Model

Alibaba's Qwen3 is selected, with advantages including strong text generation capabilities, wide knowledge coverage, outstanding reasoning abilities, and precise instruction following—making it suitable for educational scenarios.

BGE-M3 Embedding and Qdrant Vector Search

• BGE-M3: Multilingual high-quality vectorization, excellent performance in semantic similarity tasks, capturing deep semantics of educational content.
• Qdrant: Efficient similarity search, supporting real-time retrieval from large question banks with strong scalability.

Combined effects: Generate similar-style questions, avoid repetition, quickly retrieve knowledge point-related questions, and provide intelligent recommendations.

Containerized Microservice Architecture

• Service decoupling: Independent deployment of functional modules
• Elastic scaling: Dynamic resource adjustment
• Fault isolation: Single service failure does not affect the whole system
• Continuous delivery: Supports rapid iterative deployment

Next.js Analytics Dashboard

Provides data visualization:

• Test paper generation statistics (history, success rate)
• Question quality analysis (difficulty distribution, knowledge point coverage)
• Usage pattern insights (user habits and preferences)
• Real-time monitoring (system status, resource usage)

Intelligent Test Paper Generation Flow

1. Requirement Input: Users specify parameters such as subject, grade, knowledge points, difficulty, and question types
2. Knowledge Retrieval: Retrieve relevant knowledge points and reference questions from the vector database
3. Intelligent Generation: LangGraph orchestrates the agent pipeline to generate questions
4. Quality Check: Automatically check accuracy, rationality, and format compliance
5. Paper Assembly: Generate a complete document
6. Result Feedback: Generate an analysis report and support manual review and adjustment

Multi-dimensional Quality Control

• Content accuracy: Ensure the correctness and timeliness of questions
• Difficulty consistency: Meet preset standards
• Knowledge point coverage: Comprehensive and balanced
• Language standardization: Clear and standardized expression
• Format standardization: Comply with exam format requirements

Efficiency Improvement for Educational Institutions

• Shorten the test paper creation cycle
• Reduce reliance on senior question-setting experts
• Ensure difficulty balance across multiple papers
• Support large-scale personalized test paper generation

Personalized Learning Support

• Targeted practice (based on students' knowledge mastery)
• Automatically adjust question difficulty
• Generate variant questions for wrong answers to strengthen weak areas

Technical Architecture Reference Significance

• Demonstrate LangGraph's application in complex business process orchestration
• Show the role of vector databases in knowledge-intensive applications
• Provide an example of integrating large models with existing systems

The Question-Paper-Generation-System is a model project that deeply combines cutting-edge AI technology with educational scenarios. It solves practical pain points in the education field and demonstrates the powerful potential of collaborative work between multi-agent systems, large language models, vector search, and other technologies. For developers and researchers in the AI+Education direction, this project provides rich technical insights and practical references.
