+# 📁 Network Spec for LLM Understanding
+
+## 📄 Overview
+
+This repository houses a comprehensive collection of ETSI (European Telecommunications Standards Institute) documents, systematically downloaded, processed, and organized for streamlined access and analysis. Each ETSI deliverable is paired with its corresponding metadata to ensure thorough information management.
+
+## 🔍 Data Processing Workflow
+
+The data processing involves two main scripts that automate the downloading and organization of ETSI documents:
+
+1. **Download Documents**:
+    - **Script**: `organize_etsi_documents.py`
+    - **Functionality**:
+        - Reads the `ETSICatalog.csv` file to extract document information and download links.
+        - Downloads each PDF document from the provided links.
+        - Saves associated metadata for each document in a corresponding `_metadata.txt` file.
+        - Implements pause and resume capabilities to handle large downloads efficiently.
+
+2. **Organize by Working Group**:
+    - **Script**: `organize_by_working_group.py`
+    - **Functionality**:
+        - Reads the `Grouped_ETSI_Documents_with_Document_Number_by_Working_Group.csv` file to map each document to its respective **Working Group** (e.g., `GR`, `GS`).
+        - Validates the existence of both PDF and metadata files for each document.
+        - Creates dedicated folders for each Working Group within the `data/` directory.
+        - Moves the PDF and metadata files into their corresponding Working Group folders.
+        - Logs any missing or problematic files for review.

+
+- **data/**: Contains all downloaded PDFs and their corresponding metadata files, organized into subdirectories based on **Working Groups** (`GR`, `GS`, etc.).
+- **ETSICatalog.csv**: Original CSV file containing metadata and download links for ETSI documents.
+- **Grouped_ETSI_Documents_with_Document_Number_by_Working_Group.csv**: CSV file categorizing documents by Working Group and Concept.
+- **organize_etsi_documents.py**: Python script for downloading ETSI documents and generating metadata files.
+- **organize_by_working_group.py**: Python script for organizing downloaded documents into Working Group folders.
+- **requirements.txt**: Lists Python dependencies required to run the scripts.
+- **missing_files.log**: Logs detailing any missing or problematic files encountered during the organization process.
+- **organize_by_working_group.log**: Detailed log of the `organize_by_working_group.py` script's execution.
+- **README.md**: This documentation file.
+
+## 🛠️ Prerequisites
+
+- **Python 3.x**: Ensure Python is installed on your system. Download it from [python.org](https://www.python.org/downloads/).
+- **Git LFS**: Required for handling large files. Install Git LFS from [git-lfs.github.com](https://git-lfs.github.com/).
+
+## 🚀 Setup Instructions
+
+1. **Clone the Repository** (if not already cloned):
+
+    ```bash
+    git clone https://hf.co/datasets/rasoul-nikbakht/NetSpec-LLM.git
+    cd NetSpec-LLM
+    ```
+
+2. **Install Required Python Packages**:
+
+    It's recommended to use a virtual environment:
+
+    ```bash
+    # Create a virtual environment
+    python3 -m venv venv
+
+    # Activate the virtual environment
+    # On macOS/Linux:
+    source venv/bin/activate
+    # On Windows:
+    venv\Scripts\activate
+
+    # Upgrade pip
+    pip install --upgrade pip
+
+    # Install dependencies
+    pip install -r requirements.txt
+    ```
+
+    *Alternatively, install directly without a virtual environment:*
+
+    ```bash
+    pip install pandas tqdm
+    ```
+
+3. **Initialize Git LFS**:
+
+    ```bash
+    git lfs install
+    ```
+
+4. **Verify File Placement**:
+
+    - Ensure the CSV file `Grouped_ETSI_Documents_with_Document_Number_by_Working_Group.csv` is in the root directory of the repository.
+    - Ensure all PDF and metadata files are located within the `data/` directory.
+
+## 📝 How to Use
+
+### 1. **Download and Organize ETSI Documents**
+
+Ensure that `ETSICatalog.csv` is placed in the root directory of the repository.
+
+```bash
+python organize_etsi_documents.py
+```
+
+*Note: The download process may take some time depending on the number of documents and your internet connection.*
+
+### 2. **Categorize Documents by Working Group**
+
+Ensure that `Grouped_ETSI_Documents_with_Document_Number_by_Working_Group.csv` and `process-ETSI.ipynb` are correctly formatted and placed in the root directory.
+
+Run the appropriate cell in the Jupyter notebook to group the documents by Working Group.
+
+*Note: The script will move PDFs and metadata files into their respective Working Group folders. Any missing files or errors will be logged in `missing_files.log` and `organize_by_working_group.log`.*
+
+### 3. **Review the Results**
+
+- **Check the Organized Directories**:
+  - Navigate to the `data/` directory to see subfolders for each Working Group (`GR`, `GS`, etc.) containing the relevant files.
+
+- **Inspect Log Files**:
+  - `organize_by_working_group.log`: Contains detailed logs of the script's execution, including moved files and any errors.
+  - `missing_files.log`: Details any missing files or issues encountered during the move process.
+
+## 🛡️ Additional Notes
+
+- **Backup Your Data**:
+  - Before running the scripts, it's advisable to back up your `data/` directory to prevent accidental data loss.
+
+- **Handling Missing Files**:
+  - If `missing_files.log` contains entries, review them to identify and address any missing or problematic files.
+
+- **Extensibility**:
+  - The scripts are designed to handle additional Working Groups seamlessly. Simply update the CSV file with new entries, and rerun the script to organize new documents.

-    "\n",
-    "This Python script is designed to automate and optimize the processing of document files, specifically for a collection of 3GPP documents. It follows a two-step parallel processing approach to efficiently handle large volumes of files. The script operates within a specified base directory, targeting the `3GPP-all` folder, and processes documents found in its subdirectories.\n",
-    "\n",
-    "Key Features:\n",
-    "1. `file_exists`: Verifies the existence of files, ensuring efficient handling of file operations.\n",
-    "2. `unzip_task_directory`: Automates the unzipping of archives in the `3GPP-all` directory, with checks to avoid unnecessary processing of already unzipped files.\n",
-    "3. Systematic traversal through nested directory structures, identifying and preparing files for processing.\n",
-    "4. Implements `ThreadPoolExecutor` for parallel processing, significantly enhancing the efficiency of unzipping and document conversion tasks.\n",
-    "5. Innovative use of multiple LibreOffice instances for parallel\n"

-    "\n",
-    "THey key problem I had solved:\n",
-    "I ended up going with an advice for starting many libreoffice instances in parallel. This works by adding a -env:UserInstallation=file:///tmp/... command line variable:\n",
-    "\n",
-    "libreoffice -env:UserInstallation=file:///tmp/delete_me_#{timestamp} \\\n",
-    "            --headless \\\n",
-    "            --convert-to pdf \\\n",
-    "            --outdir /tmp \\\n",
-    "            /path/to/my_file.doc\n",
-    "\n",
-    "The advice itself was spotted in a long discussion to an issue on GitHub called \"Parallel conversions and synchronization\".\n",
-    "\n",
-    "GPT4 break down:\n",
-    "The response you found describes a method for running multiple instances of LibreOffice in parallel for file conversion tasks. This technique is particularly useful when you need to process a large number of documents simultaneously, which can be a common requirement in server-side applications or batch processing scripts.\n",
-    "\n",
-    "Here’s a breakdown of the response and how the method works:\n",
-    "\n",
-    "1. **Multiple LibreOffice Instances**: By default, LibreOffice is designed to run as a single instance. This can be a limitation when trying to convert multiple documents at the same time, as each conversion task would need to wait for the previous one to complete.\n",
-    "\n",
-    "2. **Using `-env:UserInstallation`**: The key to running multiple instances is the `-env:UserInstallation` command-line option. This option allows you to specify a unique user profile directory for each LibreOffice instance. By setting a different user profile directory for each instance (like using a unique `/tmp/delete_me_#{timestamp}` in the example), you essentially isolate these instances from each other.\n",
-    "\n",
-    "3. **How it Works**:\n",
-    "   - `libreoffice`: The command to run LibreOffice.\n",
-    "   - `-env:UserInstallation=file:///tmp/delete_me_#{timestamp}`: This sets a unique user profile directory. The `#{timestamp}` part is a placeholder and should be replaced with a unique identifier for each instance, such as a timestamp or a unique sequence number.\n",
-    "   - `--headless`: This option runs LibreOffice without its GUI, which is necessary for server-side or command-line operations.\n",
-    "   - `--convert-to pdf`: This instructs LibreOffice to convert the input document to a PDF. This can be changed to other formats as needed.\n",
-    "   - `--outdir /tmp`: Specifies the output directory for the converted file.\n",
-    "   - `/path/to/my_file.doc`: The path to the document that needs to be converted.\n",
-    "\n",
-    "4. **Benefits**:\n",
-    "   - **Parallel Processing**: This approach allows for true parallel processing of document conversions, significantly reducing the time required to process multiple files.\n",
-    "   - **Isolation of Instances**: Each instance operates independently, reducing the chances of conflicts or crashes affecting other instances.\n",
-    "\n",
-    "5. **Use Cases**: This method is particularly beneficial in scenarios where you have to convert a large batch of documents in a short amount of time, such as in web servers, document management systems, or batch processing scripts.\n",
-    "\n",
-    "6. **Cleanup**: Since this approach creates temporary user profiles, it's important to implement a cleanup mechanism to delete these temporary directories after the conversions are complete to avoid cluttering the file system.\n",
-    "\n",
-    "This method is an effective solution for overcoming the limitations of LibreOffice's default single-instance mode, enabling efficient parallel processing of document conversion tasks.\n"

-    "\n",
-    "This Python script is designed to automate and optimize the processing of document files, specifically for a collection of 3GPP documents. It follows a two-step parallel processing approach to efficiently handle large volumes of files. The script operates within a specified base directory, targeting the `3GPP-all` folder, and processes documents found in its subdirectories.\n",
-    "\n",
-    "Key Features:\n",
-    "1. `file_exists`: Verifies the existence of files, ensuring efficient handling of file operations.\n",
-    "2. `unzip_task_directory`: Automates the unzipping of archives in the `3GPP-all` directory, with checks to avoid unnecessary processing of already unzipped files.\n",
-    "3. Systematic traversal through nested directory structures, identifying and preparing files for processing.\n",
-    "4. Implements `ThreadPoolExecutor` for parallel processing, significantly enhancing the efficiency of unzipping and document conversion tasks.\n",
-    "5. Innovative use of multiple LibreOffice instances for parallel\n"

-    "### Use Libreoffice to convert doc files to docx and the to markdown in parallel\n",
-    "\n",
-    "THey key problem I had solved:\n",
-    "I ended up going with an advice for starting many libreoffice instances in parallel. This works by adding a -env:UserInstallation=file:///tmp/... command line variable:\n",
-    "\n",
-    "libreoffice -env:UserInstallation=file:///tmp/delete_me_#{timestamp} \\\n",
-    "            --headless \\\n",
-    "            --convert-to pdf \\\n",
-    "            --outdir /tmp \\\n",
-    "            /path/to/my_file.doc\n",
-    "\n",
-    "The advice itself was spotted in a long discussion to an issue on GitHub called \"Parallel conversions and synchronization\".\n",
-    "\n",
-    "GPT4 break down:\n",
-    "The response you found describes a method for running multiple instances of LibreOffice in parallel for file conversion tasks. This technique is particularly useful when you need to process a large number of documents simultaneously, which can be a common requirement in server-side applications or batch processing scripts.\n",
-    "\n",
-    "Here’s a breakdown of the response and how the method works:\n",
-    "\n",
-    "1. **Multiple LibreOffice Instances**: By default, LibreOffice is designed to run as a single instance. This can be a limitation when trying to convert multiple documents at the same time, as each conversion task would need to wait for the previous one to complete.\n",
-    "\n",
-    "2. **Using `-env:UserInstallation`**: The key to running multiple instances is the `-env:UserInstallation` command-line option. This option allows you to specify a unique user profile directory for each LibreOffice instance. By setting a different user profile directory for each instance (like using a unique `/tmp/delete_me_#{timestamp}` in the example), you essentially isolate these instances from each other.\n",
-    "\n",
-    "3. **How it Works**:\n",
-    "   - `libreoffice`: The command to run LibreOffice.\n",
-    "   - `-env:UserInstallation=file:///tmp/delete_me_#{timestamp}`: This sets a unique user profile directory. The `#{timestamp}` part is a placeholder and should be replaced with a unique identifier for each instance, such as a timestamp or a unique sequence number.\n",
-    "   - `--headless`: This option runs LibreOffice without its GUI, which is necessary for server-side or command-line operations.\n",
-    "   - `--convert-to pdf`: This instructs LibreOffice to convert the input document to a PDF. This can be changed to other formats as needed.\n",
-    "   - `--outdir /tmp`: Specifies the output directory for the converted file.\n",
-    "   - `/path/to/my_file.doc`: The path to the document that needs to be converted.\n",
-    "\n",
-    "4. **Benefits**:\n",
-    "   - **Parallel Processing**: This approach allows for true parallel processing of document conversions, significantly reducing the time required to process multiple files.\n",
-    "   - **Isolation of Instances**: Each instance operates independently, reducing the chances of conflicts or crashes affecting other instances.\n",
-    "\n",
-    "5. **Use Cases**: This method is particularly beneficial in scenarios where you have to convert a large batch of documents in a short amount of time, such as in web servers, document management systems, or batch processing scripts.\n",
-    "\n",
-    "6. **Cleanup**: Since this approach creates temporary user profiles, it's important to implement a cleanup mechanism to delete these temporary directories after the conversions are complete to avoid cluttering the file system.\n",
-    "\n",
-    "This method is an effective solution for overcoming the limitations of LibreOffice's default single-instance mode, enabling efficient parallel processing of document conversion tasks.\n"
