Publisher's Synopsis
In the last two decades, many online social networking sites have been developed that serve people by their interactive features. For example, a user interacts with her friends via personal posts on Facebook, uses Twitter to catch the latest news updates and share personal photographs on Instagram. People join different social communities in order to fulfill their needs; consequently, a large amount of personal information is generated on each social network. The effective retrieval and analysis of the users' shared personal information from multiple social networks may provide a logical understanding about their behavior, interest, and orientation.
Further, proper organization and re-retrieval of the users' multi-source personal information may be helpful in dealing with false information, recommendations, and online conversation (reply to a social media post).
However, retrieval of an individual's information from different sources is a tedious task due to unidentified accounts, privacy, and retrieval constraints. In the next section, we discuss the basic concept of social network, personal information and retrieval mechanism.
