Question we are trying to answer

1. • Martin Gerlach worked with a few folks in Research to create a tool a few years ago at https://list-building.toolforge.org/ -- source at https://github.com/geohci/list-building-interface . Under the hood, this tool makes use of three apis:
2. https://reader.wmcloud.org/api/v1/list-reader which looks at similar reader habits,
3. https://gitlab.wikimedia.org/repos/research/vector-search/ which does a vector search , and
4. Morelike, which we've already investigated

We should look at (1) and (2) and add rows for
the investigations from this ticket: https://phabricator.wikimedia.org/T369853

I've attached two docs:

1. A doc I put together with some preliminary findings about these APIs:
   Recommendations Deep Dive - Google Docs.pdf181 KBDownload
2. A doc Martin put together with additional context:
   Reading recommendations (Research) - Google Docs.pdf40 KBDownload

Acceptance Criteria

• Info about these APIs have been added to the research outcomes from https://phabricator.wikimedia.org/T369853
• We have determined whether we can or should to use these for our current experiments
