A Polyvocal and Contextualised Semantic Web
The document discusses the limitations of current knowledge graphs, which often reflect a single perspective and fail to address diverse viewpoints, particularly in the context of information retrieval and machine learning. It outlines challenges for creating polyvocal knowledge graphs, emphasizing the need for inclusive data representation and methodologies to capture multiple voices. The authors advocate for a collaborative effort to develop a more contextualized semantic web that incorporates diverse perspectives from various stakeholders.

- 2. What’s the problem? Mostknowledge graphs reflect the popular or majority vote Most knowledge graphs are mined from contemporary sources Most knowledge graphs represent a single perspective This poses the danger of perpetuating certain views (e.g. gender- biased, colonial-view…)
- 3. Why should Icare? Applications using single-perspective, contemporary knowledge graphs cannot adequately deal with other perspectives and/or diachronic knowledge Problematic in for example: Information retrieval and machine learning
