The thesis concerns the use of classification schemes for organising resources in subject-based hierarchical search-services on the web. The aim is to investigate the different kinds of classification that are used, which fall into two groups: established respectively new classification schemes. This is attained by studying literature and the websites of each search-service. The prospects for using classification in a web-environment are discussed and divided into three major groups: browsing, control and cross-classification. One question at issue concerns how an established scheme manages to organise web-resources and whether this classification differs from the classification of new schemes and in what way.

The purpose of this study was to investigate what knowledge 16 year old highschool students have when it comes to text- and imageposting on social media and how they act on the basis of their skills and attitudes on text and image publishing. An important aspect of this was to investigate the impact of young people 's identity in relation to text- and image posting on social media as this according to research is a big part of what motivates young people in their everyday practices (Buckingham, 2008). The essay questions was , What is young people?s experience on posting text- and image on social media? How aware are young people at the pros and cons on posting text and images on social media? What are young people's attitudes about text and image posting? And how do young people act on the basis of experience , awareness and attitude? Which role plays identity in their actions? To seek answers to my questions and achieve the aim of the thesis was conducted three semi-structured focusgroup interviews in collaboration with two high schools. The results have been reported, interpreted and analyzed by pattern-seeking. The theoretical framework used in this paper is the research and theories of primarily media researchers who have distinguished themselves in the Media and Youth research, For example, Ulla Carlsson, David Buckingham, Sonia Livingstone and Kristen Drotner.
