Semantic atlas of 188 constitutions in 3D (30k articles, embeddings)

I built this after noticing that existing tools for comparing constitutional law either have steep learning curves or only support keyword search. By combining Gemini embeddings with UMAP projection, you can navigate 30,828 constitutional articles from 188 countries in 3D and find conceptually related provisions even when the wording differs. Feedback welcome, especially from legal researchers or comparative law folks. Source and pipeline: github.com/joaoli13/constitutional-map-ai

Semantic atlas of 188 constitutions in 3D (30k articles, embeddings) launched on April 2, 2026 with 12 votes, #1,176 of 21,248 launches that month and more than 90% of that year's launches.

In plain words

Semantic Atlas is a 3D visualization tool for exploring constitutional law across 188 countries. It contains 30,828 articles from national constitutions, using AI embeddings to map conceptually related provisions together—even when they use different wording. The tool lets legal researchers and comparative law experts navigate and discover connections that traditional keyword search tools miss, without requiring specialized technical knowledge.

From the sources

Compare constitutional texts from 190+ countries on an interactive 3D semantic map. Explore rights, institutions, and legal language across the world's constitutions.

Click any country with data to load its semantic points. Drag to pan and use the zoom controls for regional comparisons. Presets are additive. The country list can be filtered by name and re-ordered for broad or focused exploration. Queries may be written in any language, but English usually works best against this corpus. Country presence reflects individual constitutional articles classified into each cluster. Constitutions that address a theme within a broad, multi-topic article may not appear even if the topic is covered. Click a row to select those countries in the map and highlight the cluster in the 3D chart. Each point in the 3D view represents a constitutional article or other…from constitutionalmap.ai

    I made a website to semantically search ArXiv papers2024 · papermatch.mitanshu.tech · ▲324

    As a grad student (and an ADHDer), I had trouble doing literature review systematically. To combat this, I made a website that finds similar papers using the meaning of the thing I am looking for. I used MixedBread's [^1] embedding model to generate vectors from the abstracts. I store and search similar vectors using Milvus [^2] and finally use Gradio [^3] to serve the frontend. I update the vector database weekly by pulling the metadata dataset from Kaggle [^4]. To speed up the search process on my free oracle instance, I binarise the embeddings and use Hamming distance as a metric. I would…

  • I mapped HN's favorite books with GPT-4o2024 · hnbooks.pieterma.es · ▲285

    Hey HN! I love finding new books to read on here. I wanted to gather the most mentioned books and recreate the serendipity of physical browsing. I scraped 20k comments from HN threads related to reading, extracted the references and opinions using GPT-4o mini, and visualised their embeddings as a map. - OpenAI's embeddings were processed using UMAP and HDBSCAN. A direct 2D projection from the text embeddings didn't yield visually interesting results. Instead, HDBSCAN is first applied on a high-dimensional projection. Those clusters tend to correspond to different genres. The genre…

    Hey HN, we're happy to release Mycelium, a JavaScript library for creating graph visualizations of machine learning models or any other directed acyclic graphs. Mycelium powers the graph viewer of the Talaria [0] a research model visualization and optimization system, which was used to optimize the efficiency of Apple Foundation Models [1]. Everything works entirely on the client-side in the browser — we provide a rudimentary ONNX loader out of the box, which you can try by dragging model files into our website. It is also simple to define loaders for your own model formats. The library was…

  • Semantic Calculator (king-man+woman=?)2025 · calc.datova.ai · ▲176

    I've been playing with embeddings and wanted to try out what results the embedding layer will produce based on just word-by-word input and addition / subtraction, beyond what many videos / papers mention (like the obvious king-man+woman=queen). So I built something that doesn't just give the first answer, but ranks the matches based on distance / cosine symmetry. I polished it a bit so that others can try it out, too. For now, I only have nouns (and some proper nouns) in the dataset, and pick the most common interpretation among the homographs. Also, it's case sensitive.

  • With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
