Despite the estimated 70 zettabytes of data produced worldwide, the production and use of data is unequal and its conversion to knowledge uneven across communities and sectors. To address this data & knowledge inequality, both the public and philanthropic sectors are increasing investments in data infrastructure and building more collaborative data ecosystems. In this talk, we’ll discuss why this matters, how knowledge graphs can help, and profile a collaborative data ecosystem where targeted investments are leading to more equitable societal outcomes. We’ll wrap up with a discussion of what the knowledge graph community can do to support the development of more equitable data ecosystems.
