“This document describes the cooperation and collaboration of BHL and Plazi, on common goals. It outlines common goals and areas of common interests, and clarifies key areas of responsibility. The digital arena allows building a large corpus of literature and from that a “graph” of knowledge or knowledge graph through identification, extraction and linking of data. It provides an emerging access platform to the knowledge beyond the conventional traditional human-reader focused access. It allows new modes of access, including text and data mining, search, visualization and the discovery of new findings based on the accessibility of data. This knowledge graph does not replace existing media, but rather complements them. In the case of biodiversity sciences, it is based on both the estimated 500 Million pages of biodiversity literature and on increasingly born-digital publications. In biodiversity, the very rich data centric publications with the highly sophisticated implicit citation networks are a perfect base to build such a knowledge graph. In order to build the knowledge graph, the data in the publications must be liberated and made open, findable, accessible, interoperable, reusable (FAIR) for machine use. This is the necessary additional step after the digitization of existing literature….”
