CORE (Connecting Repositories) is a service provided by the Knowledge Media Institute [Wikidata] based at The Open University, United Kingdom.

The first version of CORE was created in 2011 by Petr Knoth with the aim to make it easier to access and text mine very large amounts of research publications.

[4] The value of the aggregation was first demonstrated by developing a content recommendation system for research papers, following the ideas of literature-based discovery introduced by Don R. Swanson.

[6][7] CORE operates as a one step search tool for UK's open access research outputs, facilitating discoverability, use and reuse.

The CORE project started with the goal of connecting metadata and full-text outputs offering, through content aggregation, value-added services, and by opening new opportunities in the research process.

[18][19] The availability of data aggregated and enriched by CORE provides opportunities for the development of new analytical services for research literature.
