7 Uppsatser om Folksonomier - Sida 1 av 1

Från relaterat till organiserat - en studie i folksonomiers hierarkiska strukturer

Folksonomier, system som låter användare klassificera innehåll, blir allt vanligare på webben. Typiskt sker denna klassificering genom att användare fritt beskriver innehållsobjekt med hjälp av nyckelord. Denna uppsats presenterar en underökning av hur nyckelord förhåller sig till varandra hierarkiskt, inom ett folksonomisystem. Undersökningen är baserad på ett webbgränssnitt, där besökare kunde förfina eller förkasta förslag på hierarkier av nyckelord. Dessa förslag genererades utifrån av ett verkligt folksonomisystem. Efter analys av 400 inkomna svar dras slutsatsen att flera aspekter av metodologin måste förfinas för att tydliga resultat ska kunna uppnås. Förslag på sådana förändringar presenteras slutligen..

Webb 2.0 i svensk B&I-utbildning

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.

Social bokmärkeshantering på webben ? en översikt över webbplatser med användardefinierad taggning

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.

Känslan i bilden : Sociala taggars användbarhet vid bildsökning i Flickr

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.

Talande ord : En jämförande studie av taggar och kontrollerade ämnesord för indexering av skönlitteratur

How do you summarize the content of a fictional work, let?s sayLord of the Rings, into a few "telling" words that may represent it? This master?s thesis is a comparative study of how library users? freely chosen tags/keywords deviate from controlled vocabulary made by professional indexers when representing fiction. The thesis answers four main questions:? Do the tags that the library users give fictional works correspond to the categories used in professional indexing in Sweden?? Do the tags follow the standards for vocabulary, semantics and syntax used when indexing professionally?? Do the tags add something to document representations?? Are there differences between the tags used for adult fiction and the tags used for children?s literature?With a starting point in indexing theories of Frederick W. Lancaster, Annelise Pejtersen, and the semiotic theory of the indexing process of Jens-Erik Mai, 383 tags from totally 70 fictional works are analyzed.

"en labyrint av vägar" : en kvantitativ och språkfilosofisk studie av taggar och taggstruktur i Stockholms stadsbiblioteks folksonomi

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.

Svenska museer och den sociala webben: Webb 2.0 som verktyg för dialog

Museerna har genom åren långsamt utvecklats mot öppnare institutioner, vilket under de senaste decennierna har visat sig bland annat som en strävan efter dialog med museets publik. Denna utveckling har likheter med hur internet under de senaste åren blivit allt mer inriktat på deltagande och sociala aspekter, ofta kallat webb 2.0.Syftet med denna uppsats är att undersöka om svenska länsmuseer och centralmuseer använder webben för att inbjuda till dialog med sina virtuella besökare. Uppsatsen tar också upp vad denna typ av webbarbete kan ha för konsekvenser, och hur museerna skulle kunna uppnå en högre grad av interaktion på internet. De svenska läns- och centralmuseernas webbplatser har analyserats ur en genomsnittlig användares perspektiv. De aspekter som tas upp är huruvida texten eller funktionerna på webbplatserna uppmuntrar till kontakt, interaktion eller dialog med museet.
