 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...

Referências extraídas do artigo sobre controvérsias na WD indicado pelo professor Altigran na defesa de proposta D. Artz and Y. Gil. A survey of trust in computer science and the semantic web. Journal ofWeb Semantics, 5(2), 2010. Abstract Trust is an integral component in many kinds of human interaction, allowing people to act under uncertainty and with the risk of negative consequences. For example, exchanging money for a service, giving access to your property, and choosing between conflicting sources of information all may utilize some form of trust. In computer science, trust is a widely used term whose definition differs among researchers and application areas. Trust is an essential component of the vision for the Semantic Web, where both new problems and new applications of trust are being studied. This paper gives an overview of existing trust research in computer science and the Semantic Web  [Confiar a ponto de agir, mesmo assumindo riscos] 1. Introduction Trust is a centr...

Dando uma googada https://iep.utm.edu/truth/ There are two commonly accepted constraints on truth and falsehood:     Every proposition is true or false.         [Law of the Excluded Middle.]     No proposition is both true and false.         [Law of Non-contradiction.] What is the difference between a truth-maker and a truth bearer? Truth-bearers are either true or false; truth-makers are not since, not being representations, they cannot be said to be true, nor can they be said to be false . That's a second difference. Truth-bearers are 'bipolar,' either true or false; truth-makers are 'unipolar': all of them obtain. What are considered truth bearers?   A variety of truth bearers are considered – statements, beliefs, claims, assumptions, hypotheses, propositions, sentences, and utterances . When I speak of a fact . . . I mean the kind of thing that makes a proposition true or false. (Russe...

PREMISSAS (1) Pergunta potencialmente incompleta (OK) a) Qual capital Brasil?  graph query (?v1, capital de, Brasil) ... incompleta em relação ao contexto temporal e proveniência   b) Qual capital Brasil HOJE?  graph query id1 (?v1, capital de, Brasil), (id1, período, HOJE) ... completa em relação ao contexto temporal e incompleta em relação a proveniência   c) Qual capital Brasil HOJE de acordo com a Lei Federal?  graph query id1 (?v1, capital de, Brasil), (id1, período, HOJE), (id1, fonte, ?v2), (?v2, tipo, Lei Federal) ... completa em relação ao contexto temporal e a proveniência Abordagem:   Interagir em caso de pergunta incompleta? NÃO. O usuário pode ter assumido um contexto implícito e saberia completar caso questionado mas talvez nem o usuário saiba completar o contexto da pergunta (caso da Betina).

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 ”.
