Semantic Galaxy

Semantic Galaxy

A browser page that plots text embeddings in a 3D view, using the EmbeddingGemma model in ONNX form. For developers and learners who want to see how embeddings relate to each other.

Made by webml-community on Hugging Face. These notes are Mindket's, written from its Space page and README; the app's own files and license are on Hugging Face.

About

What it is: Semantic Galaxy is a web page that shows embeddings as points in a 3D space. The embeddings come from EmbeddingGemma, in the ONNX build that the Space names. It is a static front end, so it runs entirely in your browser.

Who it suits: Developers, data people and students who want to see how embeddings group together, rather than reading lists of numbers.

Industry | Who uses it | How they use it | Example
AI development | ML engineers | See how an embedding model spreads items out | Open the Space and look at the 3D view
Data science | Analysts | Build intuition for semantic closeness | Compare how nearby points relate
Education | Students | Learn what an embedding is by looking at one | Open the page and rotate the view
Web development | Front-end developers | Study a Vite and TypeScript project | Read the files under src in the repository

People who need to run embeddings at scale in a pipeline can skip it, because this is a visual demo.

Where to use it:

• A browser: the Space runs on Hugging Face with nothing to install
• Windows, macOS or Linux: open the downloaded dist/index.html in a web browser

Use case | Who | What they get back
See embeddings | Learners | A 3D picture of how items sit relative to each other
Study the build | Developers | A Vite project with its source in src

How to set it up:

• Python with pip on Windows, macOS or Linux, only to download the files
• A web browser

1. Install the Hugging Face hub package.
2. Download the Space's files into a folder.
3. Move into that folder.
4. Open dist/index.html with any browser.

pip install -U huggingface_hub
hf download webml-community/semantic-galaxy --repo-type space --local-dir semantic-galaxy
cd semantic-galaxy

How to use it: Open the Space page, or the local dist/index.html. The page shows the embeddings in a 3D view that you can look around in.

Example: You open the Space and look at the 3D view. Points that the model treats as similar sit near each other, so you can see which items the model groups together.

For newcomers and experts: If you are new, open the Space and just look. An embedding turns a piece of text into a list of numbers, and this page lets you see those lists as positions in space.

For experts, the page uses onnx-community/embeddinggemma-300m-ONNX in the browser. The repository is a Vite and TypeScript project whose built page sits in dist, with the source in src and the assets in public.

You open the page
The EmbeddingGemma ONNX model loads
It turns items into embeddings
The page draws them in 3D

Open the Space in your browser, or copy it to your own Hugging Face account from its page. Nothing in this kit runs by itself.
