About Abstract Atlas
A search-and-browse interface that places every accepted OHBM 2026 abstract in the context of a neuroscience-wide PubMed literature map. The OHBM abstracts are the submitters' own text; the clusters, related-abstract suggestions, figure interpretations, and claim extractions are computed by an automated pipeline. It is open-source and reproducible.
The cross-conference landing page — currently Abstract Atlas — puts the 3,240 OHBM 2026 abstracts in the context of a much larger neuroscience literature snapshot: NeuroScape PubMed, ~461,000 articles from 1999–2023 embedded with the NeuroScape Stage-2 model and clustered into 175 topical groups. Both layers share the same UMAP, so OHBM 2026 work appears as an overlay on the broader landscape; a binary toggle hides the overlay if you only want to browse the PubMed backdrop. From here you can drop into either site directly (OHBM 2026 · NeuroScape PubMed); the subsites are independently rebuildable and link back to this hub.
The pipeline runs in five stages, listed below. Click each one to see how it works. Surfaces that were authored or interpreted by an LLM (figure interpretations, extracted claims, LLM-grouped topic-cluster titles) carry an ✨ AI pill in the detail panel so the provenance is always visible.
Beyond the per-conference pipeline, the Abstract Atlas cross-conference landing page projects this corpus into a much larger neuroscience embedding (NeuroScape PubMed, ~461k articles 1999–2023, 175 clusters) so OHBM 2026 work can be browsed in the context of the broader literature. The NeuroScape PubMed atlas itself is the second sibling subsite, with the same UMAP and clusters but no OHBM overlay. All three subsites — Abstract Atlas (root), OHBM 2026 (this site), and NeuroScape PubMed — are independently rebuildable; the Abstract Atlas landing is the only hub that knows about all of them.
Changes
Major user-visible updates, newest first. Each entry links to the pull request (or commit) that shipped it.
-
Readable large-corpus map + live loading
The PubMed backdrop now paints a coarse quadtree tier instantly and refines as finer detail streams in on zoom, with per-point opacity that scales to how many points are on screen so the cloud stays readable at every zoom level. The map opens fitted to the whole corpus, facet toggles (including hiding NeuroScape) clear every layer, and the result count shows a live loading indicator while the full ~461k-article corpus streams in. Cross-site navigation warms sibling data more cheaply.
-
Cross-conference semantic search
Semantic search ✨ now runs on the NeuroScape PubMed atlas and the cross-conference root, not just OHBM 2026 — reusing the same in-browser MiniLM model. Search gained Damerau-Levenshtein typo tolerance and a debounced input so typing stays smooth on the 461k-article corpus.
-
Privacy-respecting analytics
Added Google Analytics gated behind a consent banner that honours Do-Not-Track and Global-Privacy-Control signals; theme variables were fixed so the banner reads correctly in dark mode.
-
Atlas rebuild + provenance speed-ups
The UMAP fit is now cached so atlas rebuilds complete in under a minute, and per-abstract AI provenance is plumbed through the parquet manifest.
-
Large-corpus performance + mobile WebGL
Performance wins for the 461k-point scatter, a graceful 2D-only fallback when a browser exposes no WebGL, and a bulk "Add N to cart" action on the root + NeuroScape sites.
-
Cross-conference atlas + NeuroScape subsite
Introduced the three-site hub-and-spoke layout: a cross-conference Abstract Atlas landing page, a standalone NeuroScape PubMed atlas (~461k articles, 175 clusters), and the existing OHBM 2026 site — built from one codebase via three site modes, with deep links routed correctly across subsites.
-
Poster-id search navigator
The search bar gained an id: operator with an autocomplete dropdown to jump straight to a poster by its program id.
-
Book of abstracts (PDF)
A deterministic book-of-abstracts PDF generator, layout polish, an acknowledgments section, and authoritative standby times wired into the UI with deep links.
-
Conference subpaths + single-file data export
Moved every OHBM 2026 surface under /ohbm2026/ to make room for sibling conferences, and redesigned the data package as a single-file Parquet with a tight schema and a poster-id as the sole user-facing identifier.
-
Static atlas launch
First public release: a static SvelteKit site with typo-tolerant lexical + semantic search, a 2D + 3D UMAP with lasso selection, a saved-list cart with email export, a guided tour, and this About page with link-checked references.
