2. Discoverability of content in repositories
Criticism of repositories (Salo, 2008; Konkiel, 2012; Acharya, 2015)
“[The institutional repository] is like a roach motel. Data goes in, but it doesn’t come out.” (Salo, 2008)

3. Why is it needed?
By integrating recommender into repositories, we can increase the number of incoming links to relevant resources, thereby increasing their accessibility.

5. Recommendations as a service
CORE provides a non-personalised recommendation system for articles from across the global network of repositories.
8 million full texts
77 million metadata records
2683 repositories

6. What effect can it have?
Increase accessibility means more engagement, higher Click-Through Rate (CTR)
Twice as often people access resources on CORE via its recommender system than via search.

9. How does the CORE recommender work?
Currently an article-article recommender system
Preprocessing prior to the recommendations: enrichment with e.g. identifiers. document type and citation data
Similarity measure/ranking function
Post-filtering using record quality
Feedback (crowdsourcing a black list)

10. What the CORE recommender is…
Use of full text rather than just abstracts
Ensure open access availability of recommended articles
Free service
Integration with repositories and availability over API

11. What the CORE recommender is not…
It is not always right! But which recommendation system is?
What the CORE recommender does not do?
Compare the “quality” of the recommended articles with the “quality” of the initial paper
Do we grasp alll the data from repositories? How clean is the data (how clean repo managers present data), identifiers are they available or not (DOIs)
We don’t have a profile for CORE users
