Editing Information explosion (section)

==Challenges==
Even though the abundance of information can be beneficial in several levels, some problems may be of concern such as [[privacy]], legal and ethical guidelines, filtering and data accuracy.<ref name="Berner, Eta S. 2005">Berner, Eta S., and Jacqueline Moss. "Informatics challenges for the impending patient information explosion." Journal of the American Medical Informatics Association 12.6 (2005): 614-617.</ref> Filtering refers to finding useful information in the middle of so much data, which relates to the job of data scientists. A typical example of a necessity of data filtering ([[data mining]]) is in healthcare since in the next years is due to have EHRs ([[Electronic Health Records]]) of patients available. With so much information available, the doctors will need to be able to identify patterns and select important data for the diagnosis of the patient.<ref name="Berner, Eta S. 2005"/> On the other hand, according to some experts, having so much public data available makes it difficult to provide data that is actually anonymous.<ref name="Sweeney, Latanya 2001"/>
Another point to take into account is the legal and ethical guidelines, which relates to who will be the owner of the data and how frequently he/she is obliged to the release this and for how long.<ref name="Berner, Eta S. 2005"/>
With so many sources of data, another problem will be accuracy of such. An untrusted source may be challenged by others, by ordering a new set of data, causing a repetition in the information.<ref name="Berner, Eta S. 2005"/>
According to Edward Huth, another concern is the accessibility and cost of such information.<ref>Huth, Edward J. "The information explosion." Bulletin of the New York Academy of Medicine 65.6 (1989): 647.</ref> The accessibility rate could be improved by either reducing the costs or increasing the utility of the information. The reduction of costs according to the author, could be done by associations, which should assess which information was relevant and gather it in a more organized fashion.
