 A Comprehensive Approach to Assess Trustworthiness and Completeness of Knowledge Graphs  International Journal of Knowledge Engineering, Vol. 10, No. 1, 2024    Abstract Completeness and trustworthiness are two dimensions that are used to assess the quality of KGs. Estimation of the completeness and trustworthiness of a largescale knowledge graph often requires humans to annotate samples from the graph. Estimativa de métricas de qualidade que dependem de interferência humana Nowadays, to reduce the costs of the manual construction of knowledge graphs, many KGs have been constructed automatically from sources with varying degrees of trustworthiness. Therefore, possible noises and conflicts are inevitably introduced in the process of construction, which severely interferes with the quality of constructed KGs.  O processo de construção automática para aumentar a completude pode degradar a confiabilidade. Introduz "fatos" incorretos ou conflitantes. we propose a ne...

 https://nesslabs.com/decision-making We make thousands of choices everyday, often automatically, using mental models we have created over years of experience. Modelos mentais: estão modelados na ROT Decision-making is the process we use to identify and choose alternatives, producing a final choice, which may or may not result in an action. It can be more or less rational based on the decision maker’s values, beliefs, and (perceived) knowledge. Decidir não agir é uma decisão também.  What’s interesting is that these areas are not only involved in the formation of a decision, but also signal the degree of confidence associated with the decision. Grau de Confiança e Grau de Risco das decisões In fact, poor decision-making rarely has to do with a lack of intelligence or information. Instead, we it’s often due to the ‘mental baggage’ we bring to the table when considering our options. Pobres em que sentido? Analysis paralysis. You may know this one under the term “overth...
