In the last years have been observed a great increase in daily collected data from the internet, mobile devices and computer systems, which are practically used in all human activity. Great part of these data comes from social network, blogs, photos and videos, sensors, besides data maintained on servers that stored web browsing logs and any user relevant action on web sites. The Big Data term refers to these kinds of data and its management requirements, which is more complex due to the volume, variety and velocity that characterise these data. Using and take advantage of this enormous amount of data is extremely complex for human without the computer aid. Recommender Systems aims to help users to find artefacts (products, documents, information, services) that might interest them. Data users are employed to do recommendations. Cold-start is characterized by lack of user data and the recommendation is very difficult in this context. In spite of the researches found in literature, the cold-start problem is still a challenge. There is no a unique solution that could be employed in different domains or situations. In this scenario, data extracted from social networks allow to do assertive recommendations to the user. This project introduces the solution for cold-start using only data extracted from social networks. (AU)
