What this shows
The map compares semantic neighborhoods among three RuFaS item types: input variables, output variables, and input files. The text description of each item was embedded using OpenAI's large embedding model, creating a high-dimensional vector representation of meaning.
DBSCAN clustering was applied to those original high-dimensional embedding vectors using cosine distance. UMAP, PCA, and t-SNE are used only as visualization methods; clustering is not performed on the 3D coordinates shown in the map.
