Improve dataset card: Add task categories, relevant tags, paper/code/project links, and update usage details

This PR significantly enhances the dataset card for `AL-GR/Origin-Sequence-Data` by:

- Adding `task_categories: ['text-generation', 'text-retrieval']` to the metadata, aligning with the paper's focus on generative retrieval and LLM training.
- Including additional `tags` (`generative-retrieval`, `semantic-identifiers`) for improved discoverability.
- Providing direct links to the associated paper, project page, and GitHub repository at the top of the README content.
- Adding an "About the Dataset" section to provide context from the paper's abstract and better explain the dataset's purpose within the FORGE benchmark.
- Renaming "How to Use" to "Sample Usage" for consistency.
- Updating the generic `_CITATION` variable within the Python loading script to the correct BibTeX citation of the paper.
- Making the license text in the content explicit by stating "Apache License 2.0" and linking to its definition.

These changes provide more comprehensive information and improve the overall utility and discoverability of the dataset on the Hub.

 # AL-GR/Origin-Sequence-Data: Raw User Behavior Sequences 📜
 
-## 📝 Dataset Summary

+## About the Dataset
 
-This repository, `AL-GR/Origin-Sequence-Data`, contains the foundational **raw user behavior sequences** for the `AL-GR` ecosystem. It represents the data *before* it is formatted into the instruction-following prompts used for training Large Language Models (LLMs).
+This dataset is part of **FORGE**, a comprehensive benchmark for **FO**rming **R**aw user behavior sequences and **G**enerative r**E**trieval in Industrial Datasets, as presented in the paper [FORGE: Forming Semantic Identifiers for Generative Retrieval in Industrial Datasets](https://huggingface.co/papers/2509.20904). The FORGE benchmark aims to address challenges in semantic identifiers (SIDs) for generative retrieval (GR) by providing a large-scale public dataset with multimodal features.
 
-Each row in the dataset represents a step in a user's journey, consisting of a sequence of previously interacted items (`user_history`) and the next item they interacted with (`target_item`). All item IDs have been anonymized into short, unique strings.
+Specifically, this `AL-GR/Origin-Sequence-Data` repository contains the foundational **raw user behavior sequences** for the `AL-GR` ecosystem. It represents the data *before* it is formatted into the instruction-following prompts used for training Large Language Models (LLMs) in generative retrieval tasks. The full FORGE dataset comprises 14 billion user interactions and multimodal features of 250 million items sampled from Taobao, one of the biggest e-commerce platforms in China.

-## 🚀 How to Use
+## 🚀 Sample Usage
 
 The data is structured in multiple folders (`s1_splits`, `s2_splits`, etc.), which is a non-standard format for the `datasets` library. To make loading seamless, a **loading script** is required.
