Dissertação (Mestrado em Ciência da Computação) - Universidade Federal de Goiás, Goiânia, 2017.http://repositorio.bc.ufg.br/tede/handle/tede/8127Retrieving information using words from a natural language is a simple and already consolidated way to access data on the Web. It would be highly desirable that a similar method could be used to submit queries on databases, thereby freeing the user from learning a query language and knowing the searched database structure. In this sense, a great research effort has been dedicated by the database community in order to develop more efficient query keywords techniques for database access. However, a keyword query can result in a large number of SQL interpretations, most of them irrelevant for the initial query. This work carry out a study of different query interpretations ranking techniques and, finally, proposes a ranking methodology that maximizes the amount of relevant results for keyword queries submitted to relational databases.application/pdfAcesso AbertoConsulta a banco de dadosInterpretação de consultaBanco de dados relacionalDatabase queryQuery interpretationRelational databaseCIENCIAS EXATAS E DA TERRA::CIENCIA DA COMPUTACAODissertação
