Data is very important for smart cities, as they significantly contribute to the strategic decision-making process for urban space. However, such a scenario is typically characterized by the high heterogeneity of data sources making the search for significant information more complex. To deal with these characteristics, ontologies have been used in conjunction with Linked Data to semantically represent information, infer new information from existing data and effectively integrate connected information from different sources. This scenario requires a data management strategy that includes efficient mechanisms to support information filtering and knowledge discovery. In this context, this work proposes a semantic search component based on the representation of georeferenced information in smart cities through ontologies and Linked Data. The semantic search component allows inferring new, non-explicit information from existing data and relationships. Experiments were performed with real-world smart city data to verify both effectiveness and efficiency of the proposed semantic search component. Cidades inteligentes são compostas por diversos sistemas interconectados, destinados a promover uma melhor gestão dos recursos urbanos e naturais das cidades, contribuindo assim para a melhoria da qualidade de vida dos cidadãos. Os dados são de grande importância para as cidades inteligentes, pois contribuem significativamente para o processo de tomada de decisões estratégicas para o espaço urbano. Contudo, tal cenário é tipicamente caracterizado pela alta heterogeneidade das fontes de dados tornando a pesquisa de informações significativas mais complexa. Para lidar com essas características, ontologias têm sido utilizadas em conjunto com o Linked Data para representar semanticamente as informações, inferir novas informações dos dados existentes e integrar efetivamente as informações conectadas de diferentes fontes. Esse cenário requer uma estratégia de gerenciamento de dados que inclua mecanismos eficientes para suportar a filtragem de informações e a descoberta de conhecimento. Nesse contexto, este trabalho propõe um componente de busca a dados semânticos baseado na representação de informações georreferenciadas em cidades inteligentes por meio de ontologias e dados vinculados. O componente de busca semântica permite inferir informações novas e não explícitas de dados e relacionamentos existentes. Experimentos foram realizados com dados de cidades inteligentes do mundo real para verificar a eficácia e a eficiência do componente de busca semântica proposto. 2021-03-03T18:27:50Z 2021-03-03T18:27:50Z 2020-11-05 masterThesis SILVA, Larysse Savanna Izidio da.

description Smart cities are composed of several interconnected systems, designed to promote better management of urban and natural resources in cities, contributing to improving the quality of life for citizens. Data is very important for smart cities, as they significantly contribute to the strategic decision-making process for urban space. However, such a scenario is typically characterized by the high heterogeneity of data sources making the search for significant information more complex. To deal with these characteristics, ontologies have been used in conjunction with Linked Data to semantically represent information, infer new information from existing data and effectively integrate connected information from different sources. This scenario requires a data management strategy that includes efficient mechanisms to support information filtering and knowledge discovery. In this context, this work proposes a semantic search component based on the representation of georeferenced information in smart cities through ontologies and Linked Data. The semantic search component allows inferring new, non-explicit information from existing data and relationships. Experiments were performed with real-world smart city data to verify both effectiveness and efficiency of the proposed semantic search component.
