Dissertação (Mestrado em Ciência da Computação) - Universidade Federal de Goiás, Goiânia, 2018.http://repositorio.bc.ufg.br/tede/handle/tede/8763Keyword query techniques have been proven to be very effective due of their user-friendliness on the Web. However, much of the data is stored in relational databases, being necessary knowledge of a structured language to access this data. In this sense, during the last decade some works have been proposed with the intention of performing keyword queries to relational databases. However, systems that implement this approach have been validated using ad hoc methods that may not reflect real-world workloads. The present work proposes a benchmark for evaluation of the methods of keyword queries to relational databases defining a standardized form with workloads that are consistent with the real world. This proposal assists in assessing the effectiveness of current and future systems. The results obtained with the benchmark application suggest that there are still many gaps to be addressed by keyword query techniques.application/pdfAcesso AbertoConsultas por palavras-chaveBancos de dados relacionaisBenchmarkKeyword searchRelational databaseBenchmarkCIENCIAS EXATAS E DA TERRA::CIENCIA DA COMPUTACAODissertação
