# T5-Based Question Generator Model
|
38 |
+
|
39 |
+
This model is a fine-tuned T5 model designed specifically for **automatic question generation** from any given context or passage. It supports different types of questions like **short answer**, **multiple choice question**, and **true or false quesiton**, while also allowing customization by **difficulty level** — easy, medium or hard.
|
40 |
+
|
41 |
+
---
|
42 |
+
|
43 |
+
## Why is this Project Important?
|
44 |
+
|
45 |
+
Educational tools, tutoring platforms, and self-learning systems need a way to **generate relevant questions** automatically from content. Our model bridges that gap by providing a flexible and robust question generation system using a **structured prompt** format and powered by a **fine-tuned `T5-base` model**.
|
46 |
+
|
47 |
+
### Key Features
|
48 |
+
|
49 |
+
- Supports **multiple question types**:
|
50 |
+
- Short answer
|
51 |
+
- Multiple choice
|
52 |
+
- True/false
|
53 |
+
|
54 |
+
- Questions are generated based on:
|
55 |
+
- The **provided context**
|
56 |
+
- The **type of question**
|
57 |
+
- The **difficulty level**
|
58 |
+
|
59 |
+
- Difficulty reflects the **reasoning depth** required (multi-hop inference).
|
60 |
+
|
61 |
+
- Uses a **structured prompt format** with clearly defined tags, making it easy to use or integrate into other systems.
|
62 |
+
|
63 |
+
- Fine-tuned from the `t5-base` model:
|
64 |
+
- Lightweight and fast
|
65 |
+
- Easy to run on CPU
|
66 |
+
- Ideal for customization by teachers or Educational platforms
|
67 |
+
|
68 |
+
### Ideal For
|
69 |
+
|
70 |
+
- Teachers creating quizzes or exam material
|
71 |
+
- EdTech apps generating practice questions
|
72 |
+
- Developers building interactive learning tools
|
73 |
+
- Automated assessment and content enrichment
|
74 |
+
|
75 |
+
### Bonus: Retrieval-Augmented Generation (RAG)
|
76 |
+
|
77 |
+
A **custom RAG function** is also provided. This enables question generation from larger content sources like textbooks:
|
78 |
+
|
79 |
+
- Input can be a **subheading** or **small excerpt** from a textbook.
|
80 |
+
- The model fetches relevant supporting context form the textbook using a retirever.
|
81 |
+
- Generates questions grounded in the fetched material.
|
82 |
+
|
83 |
+
This extends the model beyond single-passage generation into more dynamic, scalable educational use cases.
|
84 |
+
|
85 |
+
|
86 |
+
---
|
87 |
+
|
88 |
+
## Prompt Format
|
89 |
+
|
90 |
+
To generate good quality questions, the model uses a **structured input prompt** format with special tokens. This helps the model understand the intent and expected output type.
|
91 |
+
|
92 |
+
|
93 |
+
### Prompt Fields:
|
94 |
+
- `<extra_id_97>` – followed by the **question type**
|
95 |
+
- `short answer`, `multiple choice question`, or `true or false question`
|
96 |
+
- `<extra_id_98>` – followed by the **difficulty**
|
97 |
+
- `easy`, `medium`, or `hard`
|
98 |
+
- `<extra_id_99>` – followed by **[optional answer] context**
|
99 |
+
- `optional answer` – for targeted question generation, or you can leave it as blank
|
100 |
+
- `context` – the main passage/content from which questions are generated
|
101 |
+
|
102 |
+
|
103 |
+
|
104 |
+
### Helper Function to Create the Prompt
|
105 |
+
|
106 |
+
To simplify prompt construction, use this Python function:
|
107 |
+
|
108 |
+
```python
|
109 |
+
def format_prompt(qtype, difficulty, context, answer=""):
|
110 |
+
"""
|
111 |
+
Format input prompt for question generation
|
112 |
+
"""
|
113 |
+
answer_part = f"[{answer}]" if answer else ""
|
114 |
+
return f"<extra_id_97>{qtype} <extra_id_98>{difficulty} <extra_id_99>{answer_part} {context}"
|
115 |
+
|
116 |
+
```
|
117 |
+
|
118 |
+
---
|
119 |
+
|
120 |
+
## How to Use the Model
|
121 |
+
|
122 |
+
```python
|
123 |
+
from transformers import T5Tokenizer, T5ForConditionalGeneration
|
124 |
+
|
125 |
+
# Load model from Hugging Face Hub
|
126 |
+
tokenizer = T5Tokenizer.from_pretrained("your-username/t5-question-gen")
|
127 |
+
model = T5ForConditionalGeneration.from_pretrained("your-username/t5-question-gen")
|
128 |
+
|
129 |
+
# Format input prompt
|
130 |
+
def format_prompt(qtype, difficulty, context, answer=""):
|
131 |
+
answer_part = f"[{answer}]" if answer else ""
|
132 |
+
return f"<extra_id_97>{qtype} <extra_id_98>{difficulty} <extra_id_99>{answer_part} {context}"
|
133 |
+
|
134 |
+
context = "The sun is the center of our solar system."
|
135 |
+
prompt = format_prompt("short answer", "easy", context)
|
136 |
+
|
137 |
+
# Tokenize and generate
|
138 |
+
inputs = tokenizer(prompt, return_tensors="pt")
|
139 |
+
outputs = model.generate(**inputs, max_length=150)
|
140 |
+
|
141 |
+
# Decode output
|
142 |
+
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
|
143 |
+
|
144 |
+
```
