    People, who interact, cooperate or share common activities within the photo sharing system can be seen as a multirelational social network. The results of their activities, i.e. tags, comments, references to favourites and others that semantically connect users through multimedia objects, i.e. pictures are the crucial component of the semantic web concept. Every online sharing system provides data that can be used for extraction of different kinds of relations grouped in layers in the multirelational social network. Layers and their profiles were identified and studied on two, spanned in time, snapshots of Flickr population for better understanding of social network structure complexity. Additionally, for each of the identified layers, a separate strength measure was proposed in the paper. The experiments on the Flickr photo sharing system revealed that users are inspired by both the semantic relationships between objects they operate on and social links they have to other users. Moreover, the density and affluence of the social network grows over course of time

    This article explores the use of the Internet by Members of the European Parliament (MEPs), assessing the adoption of online communication as well as its strategic uses. In particular we analysed the websites, weblogs and social networking site profiles of all MEPs who linked to an online presence from the European parliament homepage, a total of 440 MEPs representing all 27 member nations. Through a thorough analysis of the content using a scheme designed to record the presence and functionality of 103 specific features and tools and recency of updates, we assess how MEPs use the Internet to connect with a range of audiences; from journalists to loyal supporters. We find MEPs embracing a range of features which would be appealing to a wide range of different visitors. There is a minor generational divide among MEPs based both on their age and the length of time their country has been a member of the European Union. However overall we suggest there is an ebb and flow of innovation within the online political communication of these parliamentarians
