As of late, explainable AI has become a very active field of research by addressing the limitations of the latest machine learning solutions that often provide highly accurate, but hardly scrutable and interpretable decisions. An increasing interest has also been shown in the integration of Knowledge Representation techniques in Machine Learning applications, mostly motivated by the complementary strengths and weaknesses that could lead to a new generation of hybrid intelligent systems. Following this idea, we hypothesise that knowledge graphs, which naturally provide domain background knowledge in a machine-readable format, could be integrated in Explainable Machine Learning approaches to help them provide more meaningful, insightful and trustworthy explanations. 6. Current challenges (and ideas to...

Trechos do texto da minha defesa de proposta In the Big Data era, the Veracity aspect explores data's consistency, accuracy, quality, and trustworthiness. Users must decide what is relevant or not, what is reliable, and which source of information they trust to consider the information accurate and helpful in carrying out the task he has in mind. [Professor Hermann comenta sobre modelos de reputação existentes]  But what do we mean by context? For this research, we adopted the general context definition from [Hogan et al., 2021]: “ By context, we herein refer to the scope of truth, and thus talk about the context in which some data are held to be true ”.
