| Social tagging networks have become highly popular for publishing and searching contents. Users in such networks can review, rate and comment on contents, or annotate them with keywords (social tags) to give short but exact text representations of even non-textual contents. Moreover, there is an inherent support for interactions and relationships among users and, thus, naturally form groups of friends or of common interests. This dissertation addresses in this area three research topics, namely: i) A comprehensive framework for search in social tagging networks and efficient top-k result retrieval. (ii) A new approach of solving the APSD Problem for dynamically update friendship relations in large user networks. (iii) Countering cheating in P2P authority computations over social networks. |
