1 Relating Personally Relevant Social Information from Heterogeneous Sources

Proliferation of online social applications and platforms has generated enormous amounts of information that could be helpful to the users. However, this information is sparse and hard to integrate. We present a framework that inter-relates information from different online sources and, with the help of a user’s personal information, is able to provide useful and relevant information from his perspective, in an iterative information seeking process. Information retrieved from the users ' devices, due to its personal and trustable character, works as a filter to information retrieved from other less trustable and structured sources. We defined a single structure to inter-relate the information as a coherent whole, instead of separate chunks. To evaluate our approach, we present an application that obtains relevant information about people. The results, analyzed together with the users, suggested that it is possible to obtain relevant and inter-related information about someone, resorting both to personal and public information
