Therefore, it is essential combination new methods of analysis for decision support system due the Big Data era. Essential information is of great value to innovation and technological development for any country. Thus, through of the data mining in patents, curriculum database and scientific papers is can be shown the presence of Big Data on health. In this sense, results shows that approach using technology forecasting and consulting databases indexed such as PubMed, Web of Science and Lattes database are rescued a large volume of data, once made the correct mining of them it is possible to get essential data to aid in decision making.
