“…Semantic network of cliques. According to the definition provided in Grilo et al (2017) and the premise of (Caldeira et al 2006), we consider a semantic network of cliques as a system of knowledge representation established by a specific context and imbued with functionality intention, where the vertices are words, concepts or entities with semantic meaning and the smallest unit of meaning is the sentence (e.g., a phrase of a text or discourse, title of a scientific paper, and keywords of a paper) and the edges consist of connections between two words that appear in the sentence.…”

“…The main models include the modeling of a system by a clique network, e.g., movie actor networks (Barabasi and Albert 1999), co-authoring networks (Newman 2001), concepts networks (Caldeira et al 2006) and semantic networks (Teixeira et al 2010;Pereira et al 2011;Pereira et al 2016;Grilo et al 2017). The latter considers the network that is composed of words, concepts or entities with semantic meaning represented by the vertices, with edges that consist of connections between two words that appear in the same unit of meaning, that is, in a sentence (phrase), paragraph or title of the analyzed speech (Pereira et al 2016;Grilo et al 2017). Semantic networks that are modeled by a clique network can provide interesting answers for the study of the organization of human language.…”

Recent work has employed information theory in social and complex networks. Studies often discuss entropy in the degree distributions of a network. However, no specific work on entropy exists in clique networks. This work is an extension of a previous study that discussed this topic. We propose a method for calculating the entropy of a clique network and its minimum and maximum values in temporal semantic networks based on titles of scientific papers. In addition, the critical network of moments was extracted. We use the titles of scientific papers published in Nature and Science over ten-year period. The results show the diversity of vocabulary over time, based on the entropy values of vertices and edges. In each critical network, we discover the paths that connect important words and an interesting modular structure.

Este trabalho propõe investigar a rede semântica de cliques baseada em ementas de um programa de pós-graduação de doutorado. Foram coletadas 46 ementas de componentes curriculares. Usando alguns índices de redes sociais e complexas como ponto de partida, observou-se que as centralidades de grau, proximidade e intermediação são índices adequados para perceber a coerência e consistência da proposta de um programa com seu ementário. E a identificação dos temas em comum às ementas auxilia na percepção das interações entre os componentes curriculares de um programa.

“…Ademais, Fadigas e Pereira (2013) propuseram um conjunto de índices para capturar as propriedades de redes semânticas de cliques e um método para caracterizar o fenômeno mundo pequeno nestas redes, utilizando como fonte de dados RST. E Grilo et al (2017) investigaram a robustez de redes semânticas de cliques.…”
