QUESTÃO CERTA: Algumas das principais técnicas utilizadas para a realização de Datamining são: estatística, aprendizado de máquina, datawarehouse e recuperação de informações.

A questão informa, claramente, que se trata de técnicas para realizar o datamining, e não que são técnicas do datamining.

QUESTÃO CERTA: Descobrir conexões escondidas e prever tendências futuras é um dos objetivos da mineração de dados, que utiliza a estatística, a inteligência artificial e os algoritmos de aprendizagem de máquina.

O processo de minerar dados para descobrir conexões escondidas e prever tendências futuras tem uma longa história. Por vezes, chamado de “descoberta de conhecimento em bancos de dados”, o termo “mineração” só foi cunhado nos anos 1990, mas sua base compreende três disciplinas científicas entrelaçadas que existem há tempos: estatística (o estudo numérico das relações entre dados), inteligência artificial (inteligência exibida por softwares e/ou máquinas, que se assemelha à humana) e machine learning (algoritmos que podem aprender com dados para realizar previsões).

Data Mining (Mineração de Dados)

Garimpagem ou mineração. BARBIERI

Busca algo mais que interpretação, inferências, tentando adivinhar possíveis fatos e correlações não explicitadas nas montanhas de dados de um DW/DM.

Permite ao usuário avaliar tendências e padrões não conhecidos entre os dados.

O Data Mining apoia o conhecimento indutivo, que descobre novas regras e padrões nos dados fornecidos. (ELMASRI, NAVATHE)
