Knowledge Representa on for Algorithmic Audi ng to Detangle
Systemic Bias

          Abstract: Knowledge is central to cognition, and adequate knowledge representation is necessary to ensure the
          correct functioning of intelligent systems leveraging knowledge. Knowledge auditing methodologies in use,
          however do not typically address the requirements for evaluating the consistency of logical and functional
          knowledge representation constructs, as used in AI, that support the correct execution of system processes. This
          paper puts forward the notion that algorithmic bias results from the lack of adequate knowledge representation
          mechanisms, and is part of systemic bias. The notion of systemic bias is identified, characterized, and described
          as an emergent relation resulting from the combination of other factors between knowledge representation (KR)
          and bias in AI. These factors are here named conceptualised, related to each other and visualised. The resulting
          artefacts are then incorporated in the KAF (Knowledge Audit Framework) methodology (first published in 2012)
          and adopted as a reference model for understanding and representing bias as a systemic emergent phenomenon.
