This was another productive year for the CORE team; our content providers have increased, along with our metadata and full text records. This makes CORE the world’s largest open access aggregator. More specifically, over the last 3 months CORE had more than 25 million users, tripling our usage compared to 2017. According to Alexa CORE is now the 5,448th most used website globally. (Alexa rank is calculated from a combination of daily visitors and page views on a website over a 3-month period.) To put this into perspective, this shows that CORE is by far one of the most used Open Access Infrastructure services globally and its usage is higher than that of many large institutions.
For yet another year (see previous years 2016, 2015) CORE has been really productive; the number of our content providers has increased and we have now more open access full text and metadata records than ever.
We also offer other services, such as the CORE Repositories Dashboard, CORE Publisher Connector and the CORE Recommender. We received great feedback with regards to the CORE Recommender, with George Macgregor, Institutional Repository Manager at Strathclyde University, reporting:
The CORE service is working in partnership with ProQuest to deliver more content within their library discovery services (Ex Libris Primo and Ex Libris Summon). What does this mean for the end user? This means that search results will bring back more relevant content from OA repositories worldwide in addition to the existing library collection records. The user will not have to go to a separate search interface to run the same search query.
CORE is continuously growing. This month we have reached 75 million metadata and 6 million full of text scientific research articles harvested from both open access journals and repositories. This past February we reported 66 million metadata and 5 million full text articles, while at the end of December 2016 we had just over 4 million full text. This shows our continuous commitment to bring to our users the widest possible range of Open Access articles.
To celebrate this milestone, we gathered the knowledge of our data scientists, programmers, researchers, and designers to illustrate our portion of metadata and full text with a less traditional (sour apple) “pie chart”.
An online editing and proofreading company, Scribendi, has recently put together a list of top 21 freely available online databases. It is a pleasure to see CORE listed as Number 1 resource in this list. CORE has been included in this list thanks to its large volume of open access and free of cost content, offering 66 million of bibliographic metadata records and 5 million of full-text research outputs. Our content originates from open access journals and repositories, both institutional and disciplinary and can be accessed via our search engine. In addition, we also offer an API and Datasets for programmable access to this content, enabling the development of new artificial intelligence-based applications for scientists and for carrying out text and data mining of scientific literature.
CORE is thrilled to announce that it currently provides 5 millions of open access full-text papers.
“In the last year, we have managed to scale up our harvesting process. This enabled us to significantly increase the amount of open access content we can offer to our users. With more and more open access content being made available by data providers, thanks to recent open access policies, CORE now also captures and provides access to a higher percentage of global research literature ”, says CORE’s founder, Dr Petr Knoth.
The past year has been productive for the CORE team; the number of harvested repositories and our open access content, both in metadata and full-text, has massively increased. (You can see last year’s blog post with our 2015 achievements in numbers here.)
There was also progress with regards to our services; the number of our API users was almost doubled in 2016, we have now about 200 registered CORE Dashboard users, and this past October we released a new version of our recommender and updated our dataset.
It is intended for (possibly computationally intensive) data analysis. Here you can read the dataset description and the download page. If you need fresh data, and your requirements are not computationally intensive, you can also use our API.
Every month Samuel Pearce, one of the CORE developers, collects the CORE statistics – perhaps a boring task, but useful for us to know where we stand as a service. A very brief report of the accumulative statistics of all years that CORE operates as a project, 2011 – 2015, are as follows.
Users can retrieve from CORE,
- 25,363,829 metadata records and
- 2,954,141 open access full-text records,
from 689 repositories (institutional and subject) and 5,488 open access journals. In addition, 122 users have access to the CORE API.
In the playful Christmas spirit we attempted this time to have some fun with the statistics.
