02 · Embedding space

Competitor map

Each alternative by how close its vector is to OCLC’s (x) and how much traffic it gets, how much of the stack it shares, or where it sits in the embedding space itself (y). Lines split each axis at the median. Hover for the numbers, click to jump to it in the list.

We can’t read oclc.org’s homepage (too little text on the homepage), so it’s compared on what Wikidata and Wikipedia say about it.
