Mapeamento da diversidade de criadores de conteúdo geolocalizado em redes geossociais em cidades brasileiras.

Abstract

Geo-Social Networks (GSNs) are a type of collaborative systems with geolocated information as their shared content. This specific content allows the linking between real and virtual worlds. Nowadays, the popularization of GSNs is something real in world. One reason of that phenomenon is because GSNs support their users during the making decision process about places. Moreover, GSNs are important tools for urban monitoring, based on flow of users’ participation. The present thesis detects as problem the way how GSNs treat their collaborators homogeneously. As consequence, GSNs do not use all collaboratives potentialities of their users and are not efficient during making decision process. We reinforce the necessity of definition of parameters about diversity of a specific user: the content creator. He presents a piece of users who shared geolocated information in GSNs. Previous studies did investigate aspects about creators’ diversity on GSNs over the world. But, none of them analyzed this diversity among content creators of GSNs in Brazilian cities. The present thesis does a large-scale mapping about geolocated content creators in cities of Brazil. This mapping is divided in three approaches. The former is the investigation of diversity, based on collaborators’ experiences about places. The next one is about diversity of content creators, according to their collaborative behaviors. The last approach is about diversity analysis, face to spatial patterns among GSNs participants. The results find out the diversity among geolocated content creators in Brazilian cities. Moreover, the results can be applied in GSNs designing and mechanism of places’ recommendation.
