15 Years of Semantic Web: An Incomplete Survey

A glimpse of Semantic Web trust

“…Trust in decisions is the degree that trusting party is willing to depend on trusted party under certain circumstances to acquire sense of security, even against the possibility of odds. Decisions made under this class, depends on the degree of risk accepted by trusting party and the previous negative or positive experiences it had toward trusted party [2]. Trust is also defined as the firm belief in the competence of an entity to act dependably, securely, and reliably within a specified context [3].…”

“…Besides many benefits of meta data, it has disadvantages. It can be created by number of resources, such as automated tools, data owner itself and other users on the Web, therefore because of non-uniform trustworthiness of meta data generators on the Web, it is imperative for each user to understand the trustworthiness level of each Meta data in order to get the full advantage of it [2]. Currently, our Web is equipped with variety of tools to ensure security of information exchange.…”

“…Members of community can use the distributed reputation score in their decisions of making transactions with other members in network. The idea behind this system is that, transactions with members with higher reputation score usually yields better results [2]. Figure 2, shows the schema of a centralized model.…”

“…However, it is the user's responsibility to distinguish right from wrong. On the other hand, in an agent based environment, where computers have to make choice over multiple and alternative sources to the requested queries, this would be achieved through harder and computationally intense processes [2]. Therefore, necessity of a mechanism to provide secure data interaction, identify the trueness of content and trustworthiness of the origin is obvious.…”

Framework formal para composição automática de serviços em sistemas de internet das coisas.

“…A maioria dos sistemas semânticos são protótipos feitos para validar hipóteses (ABANDA; TAH; KEIVANI, 2013). Ainda assim, trabalhos nessa área tem obtido bons resultados (GLIMM; STUCKENSCHMIDT, 2016). Logo, podemos afirmar que com a adesão da comunidade de desenvolvedores, teremos aplicações de IoT interoperáveis e mais escaláveis.…”
