Deepseek R1 Qwen2.5 1.5b SFT R1 JSON Unstructured To Structured

🚀 MasterControlAIML R1-Qwen2.5-1.5b SFT R1 JSON Unstructured-To-Structured Model

This repository offers a fine - tuned Qwen2 model optimized for converting unstructured text into structured JSON outputs according to a predefined schema.

This repository provides a fine - tuned Qwen2 model optimized for transforming unstructured text into structured JSON outputs according to a predefined schema. The model is finetuned from the base model MasterControlAIML/DeepSeek-R1-Strategy-Qwen-2.5-1.5b-Unstructured-To-Structured and leverages LoRA techniques for efficient adaptation.

Key Highlights:

• Developed by: bhaviktheslider
• License: Apache - 2.0
• Finetuned from: MasterControlAIML/DeepSeek-R1-Strategy-Qwen-2.5-1.5b-Unstructured-To-Structured
• Accelerated Training: Achieved 2x faster training using Unsloth and Hugging Face's TRL library.

🚀 Quick Start

This model is tailored for tasks where mapping unstructured text (e.g., manuals, QA documents) into a structured JSON format is required. It supports hierarchical data extraction based on a given JSON Schema, ensuring that the generated outputs follow the exact structure and rules defined by the schema.

Using Unsloth for Fast Inference

The Unsloth library allows you to quickly load and run inference with the model. Below is a basic example:

from unsloth import FastLanguageModel
import torch

MODEL = "MasterControlAIML/DeepSeek-R1-Qwen2.5-1.5b-SFT-R1-JSON-Unstructured-To-Structured"

# Load model and tokenizer
model, tokenizer = FastLanguageModel.from_pretrained(
    model_name=MODEL,
    max_seq_length=2048,
    dtype=None,
    load_in_4bit=False,
)

# Prepare for inference
FastLanguageModel.for_inference(model)

ALPACA_PROMPT = """
Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.
### Instruction:
{}
### Response:
{}
"""

# Example instruction and prompt
instruction = "" (see examples below)
prompt = ALPACA_PROMPT.format(instruction, "")
inputs = tokenizer([prompt], return_tensors="pt").to("cuda")
output = model.generate(**inputs, max_new_tokens=2000)

# Print generated text
print(tokenizer.batch_decode(output, skip_special_tokens=True)[0])

Using Transformers for Inference

Alternatively, you can use Hugging Face's Transformers directly:

from transformers import AutoTokenizer, AutoModelForCausalLM, TextStreamer
import torch

MODEL = "MasterControlAIML/DeepSeek-R1-Qwen2.5-1.5b-SFT-R1-JSON-Unstructured-To-Structured"

# Initialize tokenizer and model
tokenizer = AutoTokenizer.from_pretrained(MODEL)
model = AutoModelForCausalLM.from_pretrained(MODEL, torch_dtype=torch.float16, device_map="auto")

ALPACA_PROMPT = """
Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.
### Instruction:
{}
### Response:
{}
"""

TEXT = ""(see examples below)
prompt = ALPACA_PROMPT.format(TEXT, "")
inputs = tokenizer([prompt], return_tensors="pt").to("cuda")
text_streamer = TextStreamer(tokenizer)

with torch.no_grad():
    output_ids = model.generate(
        input_ids=inputs["input_ids"],
        attention_mask=inputs["attention_mask"],
        max_new_tokens=2000,
        temperature=0.7,
        top_p=0.9,
        repetition_penalty=1.1,
        streamer=text_streamer,
        pad_token_id=tokenizer.pad_token_id,
    )

print(tokenizer.decode(output_ids[0], skip_special_tokens=True))

### Role:
You are an expert data extractor specializing in mapping hierarchical text data into a given JSON Schema.

### DATA INPUT:
- **Text:** ```{TEXT}```  
- **Blank JSON Schema:** ```{SCHEMA}```  

### TASK REQUIREMENT:
1. Analyze the given text and map all relevant information strictly into the provided JSON Schema.
2. Provide your output in **two mandatory sections**:
   - **`<answer>`:** The filled JSON object  
   - **`<think>`:** Reasoning for the mapping decisions  

### OUTPUT STRUCTURE:

`<think> /* Explanation of mapping logic */ </think>`
`<answer> /* Completed JSON Object */ </answer>`



### STRICT RULES FOR GENERATING OUTPUT:
1. **Both Tags Required:**  
   - Always provide both the `<think>` and the `<answer>` sections.  
   - If reasoning is minimal, state: "Direct mapping from text to schema."
2. **JSON Schema Mapping:**  
   - Strictly map the text data to the given JSON Schema without modification or omissions.
3. **Hierarchy Preservation:**  
   - Maintain proper parent - child relationships and follow the schema's hierarchical structure.
4. **Correct Mapping of Attributes:**  
   - Map key attributes, including `id`, `idc`, `idx`, `level_type`, and `component_type`.
5. **JSON Format Compliance:**  
   - Escape quotes (`\"`), replace newlines with `\\n`, avoid trailing commas, and use double quotes exclusively.
6. **Step - by - Step Reasoning:**  
   - Explain your reasoning within the `<think>` tag.

### IMPORTANT:
If either the `<think>` or `<answer>` tags is missing, the response will be considered incomplete.

Sample Responses & Chain-of-Thought Explanations

Below are two sample outputs that include both a Chain-of-Thought Explanation (<think>) and the corresponding Filled JSON Schema (<answer>). These examples show how the model should articulate its reasoning and produce the final mapped schema.

Sample Response 1

<think>
Chain of Thought Explanation: 
To fill out the blank schema based on the Text and make it look exactly like the Filled Schema, I would start by understanding what each part represents.

First, looking at the Blank Schema, it has placeholders where actual content should go. The goal here is to replace those placeholders with appropriate data extracted from the Text so that when completed, it matches the Filled Schema perfectly.

I notice that both schemas have a similar structure, just with different types of components. My first step would be to identify how each component type maps back to elements in the Text. 

For example, in the Introduction section under "Key Metrics," there's a table listing two variables: Defect Rate at 0.5% and Yield Rate at 98%. In the Filled Schema, these become entries in the 'variables' array of a Table component. So I'd extract these values from the corresponding parts in the Text and plug them into their respective places in the Blank Schema.

Next, moving down to the Subsection titled "QA Checklists," there are checkboxes for Confirmations about defects being identified and corrected versus audits conducted regularly. Looking at the Text again, I see bullet points describing whether particular checks were done—like confirming if defects had been found—and then noting what wasn't confirmed. From this, I can infer that each checkbox corresponds to one of these confirmation statements.

Then comes the Detail Section called "Standards Overview." Here, there's another table comparing ISO 9001 and ASQ-Certified QM. In the Text, under QA Standards Comparison, they mention checking both options with clear indicators of true/false states. Therefore, I'd replicate this structure in the Blank Schema by adding these same rows of comparison details.

Throughout this entire process, my focus remains on matching each piece of textual information to its correct location within the schema without altering any other parts beyond what's specified. By methodically identifying and populating each placeholder based on the Text's content, the end result should mirror the Filled Schema precisely because every element in the filled version was accounted for during extraction.
