The aim of this thesis is to examine collaborative tagging as a potential asset to libraries by a review of 10 social bookmarking sites and their features, and a discussion of these features’ possible use when the environment changes from the web to a library. Previous research on collaborative tagging is presented, as well as overviews of social bookmarking, folksonomies and the concept of Web 2.0 and Library 2.0. The study itself is presented as a walkthrough of common features and how they work, followed by a schematic overview of which sites have which features. Finally each site is presented in a more detailed manner. An example of social bookmarking within a library, PennTags, is then also described. The results show that there are great differences to be found among the social bookmarking sites, in both features and in which tools they offer. As some features have become more common since previous similar studies, there are also one or two unique features for almost every site. Many of the younger sites have adopted the more social approach instead of being mainly an organizational tool, with an emphasis on features like groups and lists of friends. The analysis uses previous research and the results combined to answer which features could be suitable for a library environment, and how to use them. The conclusion is that many features can be considered useful in a library portal, although not all, and that the motives and preferences of each library affect which features are suitable. / Uppsatsnivå: D

The purpose of this study is to perform both a quantitative and language philosophical analysis of the folksono-my and the tags in the Stockholm public library catalogue, which together with the Umeå university folksonomy, and the folksonomy of the Norrköping public library are the only library folksonomies in Sweden. The purpose of the first part of the study is to perform an analysis of the linguistical structure of the tags in the folksonomy. To do this a quantitative analysis has been conducted to grammatically categorize and evaluate tags using a method based on Louise Spiteri‟s article “The structure and form of folksonomy tags: the road to the public library catalogue” and the SAO guidelines. This part of the analysis aims to answer questions like: what characteristics do the tags in the folksonomy have and in what ways do they separate themselves from subject headings in a controlled vocabulary? Tags were here categorized according to grammatical properties like parts of speech and their social and private characteristics. A discussion regarding different semantical problems in folksonomies was conducted along with a comparative analysis between the SSB tags and the subject headings of SAO. Based on the findings from the first part of the analysis, the second part aims to answer questions about the use and meaning of tags within a folksonomy. The later theories of Ludwig Wittgenstein are used to discuss the findings of the first analysis. There is a twofold focus here: firstly, on the potential of seeing a folksonomy as a language game, and secondly, on the private characteristics of tags. The latter being a thought that so far has been neglected in studies of library and information science. This part of the analysis aims to discuss the possi-bilities of seeing a folksonomy as a language game and what it is that makes tags in a folksonomy meaningful. It also aims to discuss the possibility of seeing tags as private sensations. Different examples and discussions from Philosophical investigations are used as a theoretical framework in the analysis. The results of the analysis show that tags in the SSB folksonomy mostly consist of single-word terms  - nouns written in indefinite and concrete article  - and that they have a high social value. They highly correlate with subject headings either fully or as see also references. It also shows that folksonomies can be seen as both primitive and more advanced language games, plus that the meanings of tags are derived from the context in which they reside and the context of the folksonomy users. Discussions also show that tags may or may not be seen as private sensations depending on individual perspectives regarding the matter.

Image indexing research today is either conducted on a visual attribute level or on a higher semantic level, forming a semantic gap between the two. There is much to gain if research progress from the two fields is combined. Image retrieval using access points in both visual and semantic significations could improve retrieval and bridge the gap. In social media today, images are often the primary communication agent and the number of images on the web is increasing in an uncontrolled way. New and efficient ways to index and retrieve the images are needed.The purpose of this study is to examine if emotions could be a semantic access point for image retrieval and if folksonomy indexing is useful when searching for images that represent emotions. Images are retrieved from Flickr and Sara Shatford’s matrix for image indexing is used to classify image tags into categories.The result shows that for some emotions it is useful and there is a clear pattern in the retrieved relevant images. For other emotions there are a lot of images that have been tagged on a cluster of images and all images in the cluster is not relevant. Therefore the search result is ambiguous.An interesting observation is that index words expressing abstractions and feelings are more common in folksonomies compared to professional indexers. For specific web image collections where searches could be conducted on feelings, folksonomies is a successful method for the indexing and retrieval of images.

This study aims to research the user perspective on interactions between authors, readers and the tagging system on the fanwork website Archive of Our Own. To answer the research questions a survey was made and sent out to users of the website via Tumblr and Reddit. In total 97 answers were received. The survey results and subsequent analysis showed us that users have similar preferences and opinions on tag usage, but have some differing opinions on the restrictions of the tag system and its affordances, as well as different views on other users’ tagging behaviors depending on if they are readers or authors. Much of the analysis stays consistent with the results of previous studies and suggestions for future research are given as a result of our own conclusions.

This thesis describes the introduction of Web 2.0 education into Swedish LIS education with emphasis on the driving forces and obstacles in the process. It also discusses the possibilities of estimating the appropriate time for the start of new educational courses introducing new technologies, when it is uncertain if the technologies in question will sustain for a long enough period of time to make the educational effort worthwhile. The data on the Web 2.0 education was collected during the spring of 2010 from the Web pages of the five LIS departments in Sweden, namely Borås, Lund, Umeå, Uppsala and Växjö, as well as by 10 interviews during November and December 2010 with two representatives from each LIS department..The key finding is that Web 2.0 is covered in Swedish LIS education and embracing both practical and theoretical issues. The main driving forces have been both the needs of the profession and an academic research interest. It is concluded that Rogers’“S-curves” as described in “Diffusion of Innovation” can be used as a tool in order to improve the understanding of when to introduce education in new technologies. Departments with no research in the new technology will probably start education in the new technology later due to the lack of scientific literature, while departments with research in the new field will have the potential to start earlier. / Program: Bibliotekarie

The main focus of this study has been to give an overview of the view on user of social tagging in research in the field of library and information science. 19 scientific articles where analyzed using qualitative texual analysis. The main focus points have been to look at the research view on user behaviour, user groups or types and user motivation, and how, and if this view has changed over time. The result shows no indication of big changes in the research. The perspective on users is changing gradually over the chosen timeframe and a more nuanced view on users is slowly becoming morepopular.This view is more centered around looking beyond the prcess of tagging as the only influence on users.
