+# On Evaluation Metrics for Complex Matching based on Reference Alignments
+
+This project is built using Python 3.12. Below are the instructions to install the necessary dependencies to run the project.
+
+## Prerequisites
+
+- Python 3.12
+
+## Data
+
+The data used in this project comes from OAEI 2020. Download the data from the following links and unzip the matchers outputs in each corresponding folder:
+`edoal/hydrography` -> [Hydrography Results 2020](https://oaei.ontologymatching.org/2020/results/complex/hydrography/hydrography_results_2020.zip)
+`edoal/populated_conference` -> [Populated Conference Results 2020](https://oaei.ontologymatching.org/2020/results/complex/popconf/results_conference.zip)
+`edoal/populated_geolink` -> [Populated Geolink Results 2020](https://oaei.ontologymatching.org/2020/results/complex/popgeolink/popgeolink_results_2020.zip)
+
+## Installation
+
+1. **Create a virtual environment:**
+
+    ```bash
+    python3.12 -m venv venv
+    ```
+
+2. **Activate the virtual environment:**
+
+    - On Linux or macOS:
+
+        ```bash
+        source venv/bin/activate
+        ```
+
+    - On Windows:
+
+        ```bash
+        venv\Scripts\activate
+        ```
+
+3. **Install the dependencies:**
+
+    ```bash
+    pip install -r requirements.txt
+    ```
+   
+4. **Run:**
+
+    ```bash
+    python main.py
+    ```
