The aim of this thesis is to examine how thesauri constructed with latent semantic indexing LSI are performing when used for query expansion. There is a well-known problem with synonymy in information retrieval and one solution to this problem is to use a thesaurus. In this thesis thesauri are created automatically to find statistically related words and not only synonyms. LSI is a method that uses singular value decomposition SVD to reduce dimensions in a matrix and find latent relationships between words. We constructed nine thesauri and used them for query expansion in a Swedish database, GP_HDINF.

The purpose of this Masters thesis is to accomplish an understanding for childrens librarians purchases of juvenile books. Two main questions are to be answered: - Which considerations do childrens librarians do when buying juvenile books and which goals and motives are behind their purchases? - What do childrens librarians think that their knowledge and competence consists of and how is that knowledge useful when buying juvenile books? To answer the questions qualitative interviews with five childrens librarians have been carried out. The material has been analyzed through a theoretical construction consisting of theories about collection development, book selection and quality judgments. The conception tacit knowledge silent knowledge from Michael Polanyi has also been used for interpretation.

The purpose of this master thesis is to study sponsoring of culture. The questions asked are: What are the reasons for sponsoring? What are the advantages of sponsoring? What are the disadvantages of sponsoring? What is the relation between public grants and sponsoring? The thesis is based upon studies of literature and a case study in Malmoe. Malmoe Public Library received about a million SEK over a period of three years from the foundation of Foreningssparbanken Skane. The money finances two projects, one with new books, Nyhetstorget, and one with strengthened information for small companies, Projekt Förstärkt Näringslivsinformation.

The aim of this Master?s thesis is to investigate the library habits of young people, age 15 to 24. Our empirical data are gathered in a survey distributed to 104 young men and women at three different public libraries. The questions are about how young people use the public library, what media and services they use and whether or not they are content with what the public library can offer them. In our analysis we have compared our results to previous research and used a model by Marianne Andersson and Dorte Skot-Hansen to determine how they use the library.

The web is a constantly growing medium that presumably plays an increasing role in public library reference services. In order to provide high quality reference service the librarians need to be able to master this medium. Therefore it is interesting to get an understanding of how librarians actually use the web. The aim of this Master s thesis is to investigate what web search tools are used by public librarians in reference service. Furthermore, the aim is to get an understanding of how the librarians think about those tools and what background factors influence their selection of tools.

Internet has made information more easy to get, but also more difficult to retrieve. There is a need for information retrieval systems that assure accurate, reliable and up to date information. Quite a number of both commercial and non commercial search services has been developed on the Internet. We have made a qualitative study of one for-pay product in particular, NetS k, produced by BTJ (Bibliotekstj nst), Lund. It is a database that contains collected, evaluated and classified links, and is especially developed to suit public librarians in Sweden.

This Master's thesis concerns the professional knowledge of the librarian. The image of this knowledge is regarded as constructed in a social context, which is why the discourse analytic approach is selected as method. The empirical material consists of two texts concerning the education of librarians. A theory of knowledge, emanating from Aristotle, is applied to the results to find examples of the forms of knowledge that are excluded from the discourse. A number of themes, or ways, in which it is possible to discuss the phenomenon of the librarian's knowledge, are identified in the texts.

The purpose of this study is to examine if digital public libraries are serendipitous environments. Serendipity in this instance is defined as finding something unexpected and valuable, while searching for something else.A survey was conducted at two Swedish digital public libraries, where the patrons were asked to fill in a questionnaire online. The questions were based on the work on serendipitous digital environments by Lori McCay-Peet, as well as considerations of human factors that could possibly influence serendipity.The result indicate that a majority of patrons experience serendipity at the digital library, although it?s still more common to do so at the physical library or on other web sites. The result also confirms the importance of taking human factors into account when studying serendipity.

The aim with this thesis came out of a strong interest for Passage Retrieval. Our intention has not been to evaluate an IR-system. Instead our goal has been to analyze the result of indexing documents and their passages. We have been studying the weights of the different terms in the different indices, in comparison with other parameters like frequency, normalized frequency and the inversed document frequency. Further more we have been looking at how the weights are spread using for instance the standard deviation.

Teaching in pre-school usually takes its starting-point in children?s reality and curiosity. Apart from that it has also been important to take contains of a special subject under consideration, for example development of language and communication or mathematics development. The purpose of this study was to investigate how natural science as a special subject in pre-school education is expressed by five trainee teachers when they teach children at the age of 2-7. Generally the study focuses on the students? teaching actions as well as their line of argument about their teaching and the choices they have to make.

The purpose of this Master's thesis is to elucidate the phenomenon of storytelling and its methodology in the context of public library story-time for pre-school children. It also strives to give an insight into the functions of story-time both with regard to the storyteller and the participating children. The study is based on qualitative methods in the form of a literature analysis, observations and interviews. The interviews were undertaken with two storytellers from the same library who work with children up to three years old and children aged between four and six years. The result of the study suggests that storytelling is more appropriate than reading aloud in situations when large groups of children are involved.

Den här rapporten är ett resultat av ett kandidatarbete på 20-poäng. Projektet som rapporten handlar om, beskriver hur utvecklingen av ett webbutikssystem åt ett flertal företag gått till. De har i sin tur köpt webbsystemet från företaget Opti Use som givit oss uppgiften. I rapporten diskuteras hur utvecklingsprocessen gått till och hur ett arbete med ett befintligt system upplevts. Rapporten beskriver även hur lösningen på uppgiften har tagit form och hur utvecklingsprocessen påverkat den.

Utveckling av planeringssystem är ett komplext designproblem som kräver både en hög grad av flexibilitet men även struktur. I samband med planering är det ett flertal aktörer, aktiviteter och resurser som måste beaktas. Kunnandet när det gäller planering finns ofta koncentrerad till ett fåtal nyckelpersoner. Det är därför ingen tillfällighet att många företag, organisationer och även universitet idag bedriver sin planering i beprövade enanvändarsystem som Excel fast att det finns starkt behov för standardiserat fleranvändarsystem. Uppsala universitet är inget undantag trots dess storlek med över 40 000 studenter, 6 200 anställda, 130 utbildningsprogram och 2000 fristående kurser.

The concepts of environmental scanning and Business Intelligence have gained increased interest over the last years in a number of different organisational contexts. The research in this field has mainly been dealing with methods and issues regarding organisation but the aim of environmental scanning, the forming of new perspectives, has been largely ignored. The purpose of this thesis is to study how Swedish joint-stock banks put environmental scanning and Business Intelligence into practice. First a literature study is made to create a background and to explain the different conceptions. Then I describe the different functions of the different services in Swedish joint-stock banks.

AIDS is a huge problem in the world and it is spreading rapidly, especially in Africa. Botswana is one of the worlds worst-hit countries, with over one-third of the inhabitants infected by HIV/AIDS. The measures that have been taken to stop the spread of AIDS are to inform and enlighten people on how the disease is spread and how to protect oneself. The aim of this thesis is to investigate what different ways of informing people about AIDS different organisations make use of in Botswana. The thesis also addresses how some receivers of the AIDS information experience it.
