Knowledge Graphs - Tracking the historical events that lead to the interweaving of data and knowledge - Leitura de Artigo

Claudio Gutierrez and Juan F. Sequeda. 2021. Knowledge graphs. Commun. ACM 64, 3 (March 2021), 96–104. https://doi.org/10.1145/3418294 ========================================================================= Data was traditionally considered a material object, tied to bits, with no semantics per se. Knowledge was traditionally conceived as the immaterial object, living only in people’s minds and language. The destinies of data and knowledge became bound together, becoming almost inseparable, by the emergence of digital computing in the mid-20th century. Knowledge Graphs can be considered the coming of age of the integration of knowledge and data at large scale with heterogeneous formats.

Researchers recognized the process of searching in large spaces represented a form of “intelligence” o...

Comentários do Sérgio em azul e complementos posteriores meus em rosa (fuchsia)  Sobre KG: ========= KG é um modelo de dados com estrutura e linguagem? Não. Da definição abaixo do survey [Hogan et. al. 2021] temos “knowledge graph is a graph of data intended to accumulate and convey knowledge of the real world, whose nodes represent entities of interest and whose edges represent potentially different relations between these entities. {It} conforms to a graph-based data model, which may be a directed edge-labelled graph, a heterogeneous graph, a property graph, and so on” Ou seja, KG são bases de conhecimento que podem ser modeladas através de modelos de dados de grafos existentes uma vez que o conhecimento neles representado contemplam entidades (do mundo real ou conceitos abstratos), propriedades que descrevem essas entidades através de seus atributos e dos relacionamentos entre essas entidades. Então: tem a parte-estrutura de um modelo mas não a parte-manipulação, no sentido de ...
