Impactstory and the Public Knowledge Project Announce Strategic Relationship

July 26th, 2017 by  | 1 Comment

PKP is pleased to announce it has entered into a strategic relationship with the mission driven non-profit Impactstory. PKP and Impactstory are excited to work together to support the adoption of open source software that enables a more open and diverse environment of scholarly activities. PKP and Impactstory will collaborate to develop, increase adoption and ensure the sustainability of alternative metrics tools and services based on open technologies.

As part of this new relationship, Impactstory is developing a free service, in conjunction with PKP, to deliver document-level metrics by leveraging the recently announced Crossref Event Data service. This new service will provide various measures of online activity including number of times a document has been mentioned on other platforms (e.g., Twitter, Wikipedia, etc); number of mentions by date; as well as any available information of each mention.  Concurrently, PKP will develop a new OJS plugin that will access the new service and display document usage information on the abstract page of any OJS-based journal.

Heather Piwowar, Impactstory co-founder said, “We are excited to build on top of the great work Crossref is doing to make altmetrics open for everyone.  PKP is a perfect partner for this, given their stature within the Open Science community and long-term commitment to working openly.”

Juan Pablo Alperin, PKP’s Associate Faculty Director of Research stated: “We jumped at the chance to work more closely with Impactstory on a new article level metrics. Heather and Jason [Impactstory co-founders] have been at the heart of the altmetrics movement and, like PKP, they are deeply committed to every aspect of openness.”

About PKP

The Public Knowledge Project was established in 1998 at the University of British Columbia. Since that time PKP has expanded and evolved into an international and virtual operation with two institutional anchors at Stanford University and Simon Fraser University Library. Open Journal Systems (OJS) is open source software made freely available to journals worldwide for the purpose of making open access publishing a viable option for more journals, as open access can increase a journal’s readership as well as its contribution to the public good on a global scale.
