Intelligent Tutoring Assessment System for the CAT

Cloning the Repository

To get started, clone the repository to your local machine by running the following command in your terminal:

git clone https://github.com/GiorgiaAuroraAdorni/bn-based-learning-networks-with-noisy-gates.git

Installation Instructions

Maven

Ensure you have Maven installed on your system. You can install Maven by running the following command in your terminal:

sudo apt update
sudo apt install maven

After installation, you can verify that Maven is installed by running:

mvn -version

Java

Ensure you have Java 11 or later installed on your system. You can install OpenJDK 11 by running:

sudo apt update
sudo apt install openjdk-18-jdk

After installation, you can verify that Java is installed by running:

java -version

Tested Environment

The code in this repository has been tested with the following versions:

• Java: 18
• Maven: 3.6.3

Method 1: Using Command Line

Run the following command in your terminal:

java -jar target/itas-1.0.jar "questions-skill.xlsx" "students-answers.xlsx" "results.xlsx" "constrained" "exact"

In the command above, replace "questions-skill.xlsx", "students-answers.xlsx", and "results.xlsx" with the paths to the appropriate XLSX files containing your questions, students' answers, and the file where you want to save the results, respectively.

Note: It's recommended to use one of the provided XLSX files or your own files following the same format.

The last two parameters, "constrained" and "exact", determine the mode of operation of the Intelligent Tutoring Assessment System (ITAS):

• Constrained Mode: In this mode, the assessment process is constrained, meaning that it strictly follows the rules and criteria defined for evaluating the students' answers. This mode typically provides more precise but potentially stricter evaluation results.
• Exact Mode: In this mode, the assessment process aims for exact inference, meaning that it tries to precisely determine the correctness of each answer based on the defined criteria. This mode may require more computational resources but can provide more accurate assessment results.

Change the content of the XLSX files to test for other models, questions, and answers.

Method 2: Using script.sh

Alternatively, you can use one of the provided .sh files to execute the experiments using Maven. Open your terminal and navigate to the root directory of the project, then run the following commands:

chmod +x script.sh
./script.sh

Ensure you have Maven installed and it's available in your system's PATH.
This method automates the process and includes predefined models and answers. You can edit the script if you want to modify the models or answers file accordingly.

Available Models and Answers

The "data" directory contains the following structure of files and folders:

• answers: This directory contains Excel files with student answers. Navigate to the appropriate subdirectory (unplugged or virtual) to find the files. You can modify these files with your preferred spreadsheet editor.

Method 1: Using Command Line

Before running the application, ensure you have generated the JAR file by following these steps:

1. Navigate to the project's root directory in your terminal.
2. Run the following Maven command to generate the JAR file:

mvn package

This command will compile the project and generate the JAR file in the target directory. Once you've generated the JAR file, you can proceed to run the application using the following command:

java -jar target/itas-1.0.jar "questions-skill.xlsx" "students-answers.xlsx" "results.xlsx" "constrained" "exact"

In the command above, replace "questions-skill.xlsx", "students-answers.xlsx", and "results.xlsx" with the paths to the appropriate XLSX files containing your questions, students' answers, and the file where you want to save the results, respectively.

Available Models and Answers

The "data" directory contains the following structure of files and folders:

• answers: This directory contains Excel files with student answers. Navigate to the appropriate subdirectory (unplugged or virtual) to find the files. You can modify these files with your preferred spreadsheet editor.

• models: Inside this directory, you'll find Excel files representing the models used in the experiments. Navigate to the appropriate subdirectory (unplugged or virtual) to find the files. You can modify these files with your preferred spreadsheet editor.

• results: This directory contains Excel files with the output results of the experiments. Navigate to the appropriate subdirectory (unplugged or virtual) to find the files. You can modify these files with your preferred spreadsheet editor.

Remember to navigate to the correct subdirectory (unplugged or virtual) depending on whether you're working with unplugged or virtual data.

Experiment Results

The experiment results will be saved in the data/results/ directory with filenames matching the respective models.
