However, the unstructured data does not necessary conducts to information. The usage of Smart Technologies to promote information and knowledge is a very important issue for independent living and wellbeing. According with [1], intelligent data analysis applied to big data, presents the following challenges: a)Increase of sensor data volume (terabytes to exabytes); b)Heterogeneity: multiple data formats and standards, mix of structured and unstructured; c)Need to quickly acquire and process intelligence information; d)Agility is required to be able to incorporate new data sources; e)Support to data exploitation: each piece of data represents some part of a situation, intelligence data contain entities that must be understood and correlated. This paper presents a methodology validated by a case study to extract information from patients’ discharge notes.
