En studie av evalueringar av webbaserade söktjänsters återvinningseffektivitet

The aim of this thesis is to describe and critically investigate eight different evaluations of the retrieval effectiveness of webbased search engines. The questions to be answered in this investigation are: - What kind of relevance judgements have been used? - Which criteria have been used when judging the relevance of a document? - Which measures have been used? - How many queries have been used? - How were the queries constructed? - What document cut-off value has been used? - Has hypothes testing been applied? - What kind of webbased search engines have been included in the evaluations? The study showed that although the evaluations investigate the same phenomena, they are very different from each other in certain aspects. Generally the study showed that precision is the preferred measure in comparison to recall in the chosen evaluation even though all the included evaluations have constructed unique formulas for calculating precision. Some attempts to measure relative recall have been performed but they all suffer from different defects.

Olikheter på arbetsplatsen. En studie om prioriteringar och marginaliseringar i svenska organisationers mångfaldsarbeten

Facilitated by the breakthrough of the internet, new ways of organizing internet-based projects that harness the power of the crowds are becoming increasingly common. Today there are ways of using the crowd as paid labour, as funders of your new project ventures and even for helping scientists doing science. Staying true to its traditional principles of objectivity and trustworthiness while asking the crowd to contribute, crowd generated ?Citizen Science? does not provide even the slightest amount of pay in exchange for the time and effort put in by their contributors. Surely there can not be many people willing to do such a thing voluntarily? Actually, practice is showing the exact opposite with contributions counted in their millions among the more popular Citizen Science projects.

Virtuella Communities: Sociala faktorer i digitala miljöer

Virtual Communities is an increasingly common phenomenon on the Internet. Most of the Virtual Communities are operated and maintained on a non-profit basis with a direction towards entertainment. However, as more state administrated and commercial services become web-based, we believe that the number of Virtual Communities with a community-based or commercial direction will increase in a near future. In this thesis, we describe our participation in, and studies of, a number of Virtual Communities with focus on the IRC-channel ?3dfxsweden?. On the basis of our experiences, we describe the social elements that form the foundation on which the Virtual Community rely on.

Omvärldsbevakning : Hur långt räcker utbildningen i biblioteks- och informationsvetenskap?

The information market is constantly changing. With new and improved information technology more people get access to more information faster. However, the number of people educated to handle information also increases. Business intelligence has for a long time been a well-known tool for companies to be competitive. Because of the increased access to information the competition between companies has intensified and more people have become aware of the advantages of business intelligence and how it can help them compete.

Svensk kunskapsorganisationsforskning 1990-2002

The purpose of this study is to characterize the research in the field of Knowledge Organization, during the period of 1990-2002, focusing on the subject and the epistemology of these studies. The result shows that studies concerning representation, e.g. subjects such as classification, indexing and bibliographic description, are the most frequently researched areas throughout the period. Classification was more popular in the beginning of the period, but later bibliographic description, mostly with studies on metadata, became more visible, together with a growing interest in information retrieval. The theoretical discussions in the studies focused primarily on document analysis and the organization of digital documents.

Rapportering om förortsproblematik i media : - Ett uttryck för stigmatiserande strukturell diskriminering eller en arena för möjlighetsorienterade politiska lösningar?

This thesis aims to examine the nature of the medial compartment regarding the reporting of problems in conjunction with suburbs. Previous research on discrimination in the media shows that people living in the suburbs considers suburbs being portrayed negatively in the media. They perceive that this has a negative effect on integration which in turn increases the risk of stigmatization. This study strives to contribute to the clarification of whether medias means of reporting around this area can help in the development of problems in suburbs by examining whether there is a reflection of actual political focus in the media or if media only plays a stigmatizing role. The research method used has been quantitative content analysis, making an overview of how much space is given to the different types of reporting. The thesis concludes that the reporting examined in this study did not appear to be of a structurally discriminatory nature, even if that type of reporting occurred.

Vad ligger till grund för användares relevansbedömningar?: En litteraturundersökning

The purpose of this thesis is to get an improved understanding of what the bases for relevance are, when people in real information need situations make relevance judgements. In order to meet this purpose, an investigation based on research literature is performed. Four types of relevance are investigated: topical or subject relevance, cognitive relevance or pertinence, situational relevance or utility, and socio-cognitive relevance. The investigation also deals with users relevance criteria identified in fourteen empirical studies, in which the users are adults and engaged in oral, textual, and multimedia information retrieval. Finally, the connections between the user criteria found and the types of relevance are discussed.

Utopia Trek : utopibegreppets resa genom Star Trek

Humanity has always dreamed about a better world. These dreams has manifested themselves in the vision of Utopia - the good place, but also the non-existing place. Up until World War II man still wrote optimistic descriptions of this ideal world, and spread the idea through literature.

Naturlika planteringar - hur lika och hur är de lika naturen? :

Sammanfattning (English below) Jag har alltid tyckt om naturen och haft en föreställning om att all växtlighet som inte är tydligt anlagd, som en gräsmatta eller en rabatt, är något som naturen åstadkommit av sig själv. Mina ögon öppnades för alternativen när jag för första gången hörde begreppet ?naturlik plantering?. Det här arbetets syfte är att ta reda på hur lik naturen naturlika planteringar egentligen är, om de är planerat naturlika eller något som används som utfyllnad. Syftet är också att ge en indikation på vilken status den naturlika planteringen har. Arbetet består av tre delar. En historisk del som utforskar ursprunget till begreppet ?naturlik?.

Strategisk retoriker eller bara bitter och arg? : - en retorisk analys av krönikören Linda Skugge

AbstractAim: The aim of the study is to analyze ten different columns written by Linda Skugge, in order to see what kind of rhetorical means she uses to get her message across. It is also to examine if, and to what extent, these means are of female nature, and to see what kind of persona Skugge uses in order to be trustworthy.Method: Rhetorical analysis of ten columns written by Linda SkuggeMain results: The study has shown that Skugge´s rhetorical strategies differ from the ones recommended in theories about female speech. Skugge writes with a lot of character and emotionally based arguments, which, according to the theories, is more of a male way of speaking. Skugge gives an impression of being strong, competitive and offensive in her character, but also reveals that her role is consciously chosen in order to receive respect and to gain power.Number of pages: 42Course: Media- and Communication studies DUniversity: Department of Information science, University of UppsalaPeriod: Spring 2005Tutor: Amelie HössjerKeywords: rhetoric, rhetorical analysis, feminist studies, persona, Linda Skugge.

Tillgängligt landskap : spänger i naturmark

The title of this thesis is ?Accessible Landscape - boardwalks in nature areas?. The main purpose of this thesis is to show how you can increase the accessibility for disabled people by constructing boardwalks in nature areas. The platform for the thesis is a study of litterature on boardwalks, accessibility and disabilities. After defining these terms I made three excursions to three different locations in the south of Sweden. During the excursions I evaluated the boardwalks situated in each of the areas through preferences such as the construction of the boardwalk, its design and the accessibility. After the excursions I interviewed managers of the areas I visited, and people working with disability questions in the municipalities where the excursions took place. To know how to make a boardwalk accessible you need to have knowledge about certain concepts, rules and recommendations. My thesis deals with aspects such as: *Accessibility *Disability *Rules and recommendations when building boardwalks *Real life - evaluation from the excursions and interviews with the managers The result shows that accessibility is a hot topic in Sweden and a lot of improvement is being done with fi nancial support from the European Union.

EU och folkomröstningarna En undersökning om de europeiska ländernas skiftande karaktär och hur dess väljare agerat i förhållande till detta

33 referendum has taken place in european states regarding the European Union since the fall of the Berlin wall. This thesis aims to initialy identify potential patterns in this group of referenda to launch and test a theory/hypothesis anchored in this pattern.The european states are differing in nature and the standard of living is chosen as the factor that can potentially have affected the outcome of the referenda held. The carrying thought here being that the voters in states with considerably lower standard of living than the european average would have a more positive attitude towards a deepened cooperation among european states.To try this connection between standard of living and how european citizens have placed their votes a main and principal quantitative test is undertaken. It is followed by discussion and arguments about the result of the test.The argumentation goes from being hopefull of the strenght of the hypothesis, to a more ciritical view of its' strength. The thesis is wrapped up in some argumentation about how and why it fails to explain what it was initially intended to do.

Förskolegårdens utformning och dess påverkan på barns lek

The purpose of this essay is to examine the impact on children playing at a preschool yard that is designed with traditional playground equipment, and a nature-like yard without traditional playground equipment. How these respective environments influence children?s play, which other factors in the external environment that affect the game and whether the theories in the literature correspond with the results were important questions for the essay. To answer these questions a case study was applied onto two specific preschool centers, both located in Malmö. Through literature studies, inventories, observations and interviews with staff and children, a picture become clear of how the children use the yard and how their play is affected by the design of it.

Hör upp!!

In this Bachelor thesis I explore sound and room as elements in design of user interfaces, both theoretical and practical in a specific application domain, to identify some of the advantages and disadvantage associated with these elements. As application domain I studied email clients and their usage at home amongst students at Blekinge Institute of Technology. In the study I found an activity, which seems to be highly distributed in the physical room where the user is located. The activity was notification of email and could take place in an arbitrary location of the home. I then augmented this activity with ideas from my theoretical assumption about room and sound. The result was a rule-based agent for notification of email, which primarily uses sound as interaction style..
