Latent Dirichlet Allocation (LDA) topic modeling is a fascinating technique that helps in discovering abstract topics within a collection of documents. This article will guide you through the setup and execution of a PureScript implementation designed for the browser, allowing you to perform LDA on your documents effortlessly.

Getting Started

Before you dive in, make sure to have Git and Node.js installed on your machine. The whole process is quite easy and straightforward. Follow these steps to get your LDA Topic Modeling application up and running!

Step 1: Clone the Repository

You’ll first want to clone the LDA topic modeling GitHub repository to your local machine.

git clone git@github.com:lettier/lda-topic-modeling.git

Once cloned, navigate into the project directory:

cd lda-topic-modeling

Step 2: Install Dependencies

Next, you should install Node Version Manager (NVM) if you haven’t already, along with npm (Node Package Manager). This will help manage the Node.js installations and packages for your project.

nvm use

npm install -g bower

npm install

bower install

Step 3: Build the Project

With all dependencies in place, run the build command:

npm run build

Step 4: Start the Server

Now it’s time to launch your application! Navigate to the build directory:

cd build

Then, start a simple HTTP server:

nohup python -m http.server devnull

And open it in your web browser:

python -m webbrowser http://localhost:8000

Understanding the Code: An Analogy

Imagine you are a librarian in a vast library filled with countless books (documents). Each book contains different subjects (topics). LDA works like an expert librarian that reads several books and organizes them into clusters based on the topics they discuss. For instance, it might find that some books talk about gardening, while others focus on cooking, and still, others discuss technology. By identifying these clusters, LDA helps users discover the main themes present in their reading material.

Troubleshooting

If you encounter issues during the installation or execution, consider the following suggestions:

• Ensure that Git and Node.js are correctly installed and available in your system PATH.
• If the server does not start, check for port collisions or firewall settings that might be blocking the connection.
• If you experience issues with missing dependencies, retry the installation steps carefully, ensuring all commands are executed without errors.
