Improve model card: Add pipeline tag, library name, tags, project page, and sample usage

This PR significantly enhances the model card for the ReasonRank model by:
- Adding `pipeline_tag: text-ranking` to ensure discoverability under relevant tasks on the Hugging Face Hub.
- Specifying `library_name: transformers` to enable the "How to use" widget and indicate compatibility with the 🤗 Transformers library.
- Including relevant `tags` such as `qwen`, `reranker`, and `passage-ranking` for improved searchability.
- Integrating comprehensive details from the original GitHub repository, including a model overview, training data specifics, and performance results.
- Providing a practical Python code snippet for `Sample Usage` to help users quickly get started with inference.
- Ensuring links to the project page and original paper are present and consistent.

+## 1. ReasonRank
+
+### 💡 1.1 Overview
+
+**ReasonRank** is a **reasoning-intensive passage reranker** tailored for reasoning-intensive ranking tasks. To train it, we first design an automated reasoning-intensive training data synthesis framework and synthesize 1.3k high-quality training data.
+
+<p align="center">
+<img width="80%" alt="image" src="https://8421bcd.oss-cn-beijing.aliyuncs.com/img/image-20250809002302377.png" />
+</p>
+
+Based on the training data, we design a two-stage training approach including **cold-start SFT** and **multi-view ranking reward RL** to inject listwise ranking ability to our ReasonRank.
+
+<p align="center">
+<img width="80%" alt="image" src="https://8421bcd.oss-cn-beijing.aliyuncs.com/img/image-20250809002546838.png" />
+</p>
+
+### 📊 1.2 Overall Performance
+
+When using ReasonIR as initial passage retriever, our ReasonRank demonstrates strong overall ranking performance on BRIGHT benchmark, while showing superior efficiency compared with pointwise reasoning-intensive reranker Rank1.

+Besides, when using a higher-quality retrieval results (RaDeR + BM25 hybrid, provided by [RaDeR](https://github.com/Debrup-61/RaDeR/blob/main/BRIGHT_score_files/RaDeR-gte-Qwen2-LLMq_CoT_lexical/aops/hybrid_BM25_Rader.json)), our ReasonRank (32B) achieves SOTA performance **40.8** on [BRIGHT leaderboard](https://brightbenchmark.github.io/).
+
+## 📂 2. The Introduction of ReasonRank Training Data
+
+An important contribution of our work is our reasoning-intensive training data ([reasonrank_data_13k](https://huggingface.co/datasets/liuwenhan/reasonrank_data_13k)). The dataset fields of ``training_data_all.jsonl`` are as follows:
+
+#### **Dataset Fields & Descriptions**
+
+1. **`dataset`** *(str)*
+   - The dataset name of each piece of data (e.g., `"math-qa"`).
+2. **`qid`** *(str)*
+   - The query ID. The content is provided in ``id_query/`` directory.
+3. **`initial_list`** *(List[str])*
+   - The initial list of passage IDs before DeepSeek-R1 reranking. The content of each passage ID is provided in ``id_doc/`` directory.
+4. **`final_list`** *(List[str])*
+   - The re-ranked list of passage IDs after listwisely reranking with DeepSeek-R1.
+   - Reflects the improved ranking based on reasoning-enhanced relevance scoring.
+5. **`reasoning`** *(str)*
+   - A  **step-by-step reasoning chain** outputted by DeepSeek-R1 while performing the listwise reranking.
+6. **`relevant_docids`** *(List[str])*
+   - The ids of relevant passages in ``initial_list`` mined by DeepSeek-R1. The remaining passage ids in ``initial_list`` are irrelevant ones. 
+   - Note that **`relevant_docids`** are not necessarily ranked at the top of **`final_list`** by the DeepSeek-R1, which may stem from inconsistencies in DeepSeek-R1’s judgments. To address this, you can apply the **self-consistency data filtering** technique proposed in our paper to select higher-quality data.
+
+The statistics of dataset is shown in the figure below:
+<p align="center">
+<img width="80%" alt="image" src="https://github.com/user-attachments/assets/c04b9d1a-2f21-46f1-b23d-ad1f50d22fb8" />
+</p>
+
+#### **Example Entry**
+
+```json
+{
+  "dataset": "math-qa",
+  "qid": "math_1001",
+  "initial_list": ["math_test_intermediate_algebra_808", "math_train_intermediate_algebra_1471", ...],
+  "final_list": ["math_test_intermediate_algebra_808", "math_test_intermediate_algebra_1678", ...],
+  "reasoning": "Okay, I need to rank the 20 passages based on their relevance...",
+  "relevant_docids": ["math_test_intermediate_algebra_808", "math_train_intermediate_algebra_1471", "math_train_intermediate_algebra_993"]
+}
+```
+
+#### **Application**
+
+1. Training passage reranker: Given the reranked passage list, one can use our data to train a listwise reranker
+2. Training passage retriever: Using the **`relevant_docids`** and the remaining irrelevant ids, one can train a passage retriever.
+
+## ⚡ 3. Quick Start
+
+This section provides a general guide on how to use ReasonRank for inference. For detailed environment setup, specific inference commands (including usage with ReasonIR or custom retrieval results), and in-depth training procedures (Cold-Start SFT, Multi-reward ranking RL), please refer to the [official GitHub repository](https://github.com/8421BCD/ReasonRank).
+
+## Sample Usage
+
+This model can be loaded and used with the `transformers` library. Below is a basic example demonstrating how to use the model for passage re-ranking. The model expects a specific chat-like format for input, including a system prompt and a user query with listed passages.
+
+```python
+import torch
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+model_name = "liuwenhan/reasonrank-7B" # Or "liuwenhan/reasonrank-32B"
+
+tokenizer = AutoTokenizer.from_pretrained(model_name)
+model = AutoModelForCausalLM.from_pretrained(
+    model_name,
+    torch_dtype=torch.bfloat16,
+    device_map="auto",
+    trust_remote_code=True
+).eval()
+
+# System prompt as used in the paper for reasoning-intensive ranking
+system_prompt = (
+    "You are a helpful and harmless AI assistant. You will be provided with a search query and a list of passages, "
+    "and your task is to re-rank the passages based on their relevance to the query. "
+    "You should follow a chain of thought to determine the most relevant passages. "
+    "Your final answer should be a list of the re-ranked passage numbers, separated by commas. "
+    "Do not include any other information or explanation in your final answer."
+)
+
+query = "What is the capital of France?"
+passages = [
+    "Paris is the capital and most populous city of France.",
+    "The Eiffel Tower is a famous landmark in Paris.",
+    "France is a country located in Western Europe.",
+    "London is the capital of the United Kingdom."
+]
+
+# Construct the user message with query and passages
+user_content = f"Search Query: {query}
+"
+for i, passage in enumerate(passages):
+    user_content += f"[{i+1}] {passage}
+"
+user_content += "Please re-rank the passages based on their relevance to the query. Provide a chain of thought and then the final re-ranked list."
+
+messages = [
+    {"role": "system", "content": system_prompt},
+    {"role": "user", "content": user_content}
+]
+
+# Apply chat template
+input_text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
+
+# Tokenize input
+input_ids = tokenizer.encode(input_text, return_tensors="pt").to(model.device)
+
+# Generate response
+output_ids = model.generate(
+    input_ids,
+    max_new_tokens=256, # Adjust as needed for reasoning length
+    do_sample=False,    # Typically deterministic for ranking/reasoning
+    temperature=0.1,    # Low temperature for focused output
+    repetition_penalty=1.05,
+    eos_token_id=tokenizer.eos_token_id
+)
+
+# Decode output
+generated_text = tokenizer.decode(output_ids[0][input_ids.shape[1]:], skip_special_tokens=True)
+print(generated_text)
+```
