+# NLP-ADBench: NLP Anomaly Detection Benchmark
+
+This repository contains **NLP-ADBench**, the most comprehensive NLP anomaly detection (NLP-AD) benchmark to date. It is a comprehensive benchmarking tool designed for Anomaly Detection in Natural Language Processing (NLP), establishing a benchmark and introducing 8 curated and transformed datasets derived from existing NLP classification datasets. These datasets are specifically tailored for NLP anomaly detection tasks and presented in a unified standard format to support and advance research in this domain.
+
+The benchmark includes results from 19 algorithms applied to the 8 NLPAD datasets, categorized into two groups:
+- 3 end-to-end algorithms that directly process raw text data to produce anomaly detection outcomes.
+- 16 embedding-based algorithms, created by applying 8 traditional anomaly detection methods to text embeddings generated using two models: BERT's `bert-base-uncased` (**BERT**) and OpenAI’s `text-embedding-3-large` (**OpenAI**).

+
+## NLPAD Datasets
+
+The datasets required for this project can be downloaded from the following Hugging Face links:
+
+1.  **NLPAD Datasets**: These are the datasets mentioned in the NLP-ADBench paper. You can download them from:
+    -   [NLP-AD Datasets](https://huggingface.co/datasets/kendx/NLP-ADBench/tree/main/datasets)
+
+2.  **Pre-Extracted Embeddings**: For embedding-based algorithms, pre-extracted embeddings are provided. If you want to use them directly, you can download them from:
+    -   [Pre-Extracted Embeddings](https://huggingface.co/datasets/kendx/NLP-ADBench/tree/main/embeddings)
+
+## Sample Usage
+
+To run the benchmark, first set up the environment and import the pre-extracted embeddings:
+
+### Environment Setup Instructions
+
+1.  **Install Anaconda or Miniconda**:
+    Download and install Anaconda or Miniconda from [here](https://docs.conda.io/en/latest/miniconda.html).
+
+2.  **Create the Environment**:
+    Using the terminal, navigate to the directory containing the `environment.yml` file in the GitHub repository and run:
+    ```bash
+    conda env create -f environment.yml
+    ```
+3.  **Activate the Environment**:
+    Activate the newly created environment using:
+    ```bash
+    conda activate nlpad
+    ```
+
+### Import data
+
+Get `Pre-Extracted Embeddings` data from the [Hugging Face link](https://huggingface.co/datasets/kendx/NLP-ADBench/tree/main/embeddings) and put it in the `data` folder.
+
+Place all downloaded embeddings data into the `feature` folder in the `./benchmark` directory of this project.
+
+### Run the code
+Run the following commands from the `./benchmark` directory of the project:
+
+#### BERT
+If you want to run a benchmark using data embedded with BERT's `bert-base-uncased` model, use this command:
+````bash
+python [algorithm_name]_benchmark.py bert
+````
+
+#### OpenAI
+If you want to run a benchmark using data embedded with OpenAI's `text-embedding-3-large` model, use this command:
+````bash
+python [algorithm_name]_benchmark.py gpt
+````
