Rationale Readers of this blog will be familiar with Open Citation Identifiers (OCIs), described in an earlier post and formally defined in [1]. OCIs enable bibliographic citations, treated as first class information entities, to be uniquely identified and referenced, and are used to identify the >624 million individual citations indexed in the latest release of COCI, the OpenCitations Index of Crossref open DOI-to-DOI

The creation of the Open Biomedical Citations in Context Corpus (CCC) is the goal of a one-year project funded by the Wellcome Trust. The aim is to create a new open corpus of bibliographic and citation data that contain detailed information about individual in-text reference pointers in biomedical journal articles.

We are now proud to announce the third release of COCI, which contains more than 624 million DOI-to-DOI citation links coming from both ‘the ‘Open’ and the ‘Limited’ sets of Crossref reference data.

The Global Sustainability Coalition for Open Science Services (SCOSS) is launching its second funding cycle, and OpenCitations is one of three open science infrastructure organizations whose services have been evaluated and selected for presentation to the international scholarly community for crowd-sourced sustainability funding, along with the Public Knowledge Project (PKP) and the Directory of Open Access Books (DOAB). OpenCitations is an

Among the external services used, the ORCID Public API is of crucial importance for the task of author disambiguation. During the OCC ingestion workflow, the main metadata of an article are usually retrieved from the Crossref API.

The OpenCitations Enhancement Project Final report for the Alfred P. Sloan Foundation Report period: 1st May 2017 – 30 November 2018.

The Open Biomedical Citations in Context Corpus funded by the Wellcome Trust The Wellcome Trust, which funds research in big health challenges and campaigns for better science, has agreed to fund The Open Biomedical Citations in Context Corpus , a new project to enhance the OpenCitations Corpus, as part of the Open Research Fund programme.

As introduced in a previous blog post, COCI is the OpenCitations Index of Crossref open DOI-to-DOI references, all released as CC0 material.

In a previous series of blog posts we proposed the treatment of bibliographic citations as first-class data entities, permitting citations to be endowed with descriptive properties.
