    A System for Specifying Semantic Relations for Knowledge Representation
    (Ergon - ein Verlag in der Nomos Verlagsgesellschaft, 2020) Maia, Lucinéia Souza. Lima, Gercina Ângela de.
    Semantic relations are fundamental for understanding the nature of the connection between two concepts in a domain. This paper presents a model for extracting semantic relations for the representation of knowledge from academic documents in the context of the Portuguese language. A Web information system called Se- mantizar was developed to support the extraction of semantic relations from classificatory structures that rep- resent specific academic documents. To evaluate the qualitative performance of Semantizar, a case study was carried out, which pointed to important contributions to research about semantic relations extraction. Accord- ing to outcomes, when two concepts of a classificatory structure exist in a sentence, a semantic relationship between them can actually exist. Finally, it is concluded that this research is relevant because it brings im- portant findings for the extraction of semantic relations for the knowledge representation of academic docu- ments to be applied in the Brazilian scenario.

    A SEMANTIC-RELATIONS TAXONOMY FOR KNOWLEDGE REPRESENTATION
    (Brazilian Journal of Information Science: Research trends, 2021-09-28) Maia, Lucinéia Souza. Lima, Gercina Ângela de.
    Concepts are units of knowledge and, the relationships link these units, which gives the meaning as represented. Semantic relations in knowledge representation characterizes the association between the concepts of a domain. In this way, semantic relations allow users to assimilate the association between concepts in a domain. These relationships are essential because they serve as a basis for representing and structuring a domain of knowledge. Thus, the studies on semantic relations have been accomplished by several researchers from different areas of knowledge, approaching a different point of view, which resulted in a terminological variation. The objective of this proposal of the taxonomy of semantic relations arose precisely to solve this problem. In this sense, exploratory research was carried out using the methodological procedure literature research following criteria that pointed out the most relevant approaches to types of semantic relations. As result, a taxonomy was arrived at of sixty-three semantic relations, including the new relationships found from this study, nicknamed here "subordinate agent”.
