Word sense disambiguation med Svenskt OrdNät
In information retrieval there is a problem with ambiguous words. To solve this problem word sense disambiguation WSD is used. Few studies combining information retrieval and word sense disambiguation have been conducted with Swedish words. The purpose of this thesis has been divided in two. The first purpose was to examine Swedish information retrieval and disambiguation in the query phase.
Typer av sökfrågor på webben: En effektivitetsstudie
The purpose of this thesis is to examine the performance of different types of queries in the AltaVista query-based search engine. Thirty information needs have been collected from an ask-a-question service on the World Wide Web, which means that they are based on real users information needs. This is done to avoid partiality in the study. The author has invented different types of queries for each and every one of the information needs in accordance with the search syntax available for AltaVista. The types used are Boolean expressions, queries including proximity operators, phrases and queries directed towards a specific field.
Lustfyllda möten med böcker och bibliotek: barnbibliotekariers läsfrämjande metoder för sexåringar, samt läsning och böcker för den åldern
In this thesis I investigate what librarians working with children do for six-year-olds at the libraries in order to stimulate them to read. I also investigate how children of this age read and what books are like for these beginners. The background for the thesis is that reading decreased a lot in ages three to eight during the 1980s and 1990s. My aim is to see what projects, methods and other strategies there are to get children to read. The method used is case study.
Folkbibliotek och resursfördelning. En jämförande studie av sju folkbibliotek i Uppsala kommun.
Allocation of funds to public libraries is uneven and this study will try to explain the reasons and clarify why the allocations of funds are distributed like they are and what calculations influenced the financial apportionment. This master thesis accounts for allocation in seven public libraries in Uppsala. The study shows that one reason for uneven allocations is demographic. Another reason is that the library has come into a good or bad circle. There are no models for allocation of funds to public libraries in Uppsala, thats why their allocations are given after a percentage increase of earlier years allocations, and that leads to a good or bad circle.
Skolbiblioteket på friskolorna : en studie av friskolorna i Lunds kommun med fokus på de verksamhetsansvarigas inställning
The purpose of this master thesis is to examine the opinion about school libraries among principals at the independent schools in the municipality of Lund. In order to fulfil my purpose I used a qualitative method with an introductory questionnaire, which gave background material to the interviews. All seven principals answered the questionnaire and five of them agreed to participate in an interview. Another two interviews were made with two informants, this material was included in the background material. As theoretical framework I have used literature about the school library development, the role of the principal for development and David V.
Kvinnan:mannen::alternativet:normen ett feministiskt perspektiv på klassifikation
Using a feministic perspective and a critical approach, my purpose is to discuss bibliographic classification, a central aspect of Library and Information Science. More specifically, my aim is to demonstrate the norms and the dominating thoughts regarding the organization and representation of knowledge, subjects, and social categories in classification systems. I review previous research involving critical approaches to classification. These show that classification systems are a reflection of the context in which they are created, with the result that universal assumptions can be questioned. Some studies also present problems inherent in hierarchical structures.
Industriforskning och informationssökning: en användarstudie av en grupp forskare vid ABB Corporate Research
The thesis aims at, from a user perspective, examining how a group of industrial researchers understand the information seeking in their every day work. A qualitative method is employed. The empirical material consists of open-ended interviews with in all ten researchers. All of them work at the Swiss-Swedish Technology Company ABB's research laboratory in Västerås. The thesis is based on the opinion that the scientific knowledge production has become commercialised and that the scientific communication is going through certain changes.
Silversurfarna med hela världen i en låda Användarundervisning i internet för sju ålderspensionärer
Today, librarians tasks may sometimes take on an educational aspect, e.g. when designing educational courses. Our aim with this paper has been to extend our knowledge of peoples learning and learning processes in order to better adapt our educational courses for different user groups. We have investigated what eight senior citizens wanted to learn about the Internet, and followed seven of them during their course. We have examined how the group experienced a course about Internet use, and how they described their learning and learning processes.
Information om information : En hermeneutisk studie av informationsbegrepp inom informationsfilosofi och biblioteks- och informationsvetenskap
Abstract: The aim of this study is to investigate the attitudes towards the labour movement?s strategies, goals and organisational issues in Swedish Miners? Union?s (Gruvindustriarbetareförbundet, hereafter Gruv) paper, Gruvarbetaren 1917-1925.The theoretical starting point is Engels? view on the class state. This perspective turns the question of socialism and the way to get there into an issue of working class power over the state. Another theoretical perspective is the partition of the labour movement into a trade-unionistic branch, seeing unions as financial organisations of interest, and a pro-state one, considering unions as political organisations.During the period investigated Gruvarbetaren was quite radical and advocated a firm class struggle strategy towards employers. Since these were considered unreliable, class struggle was seen as the only way to better the conditions for the working class.
Bibliotekets roll i integrationspolitiken ett postkolonialt perspektiv
Sweden of today is a so-called multicultural society. In this thesis we wanted to examine how mono, multi- and intercultural issues are expressed in culture-political documents. We also wanted to know how librarians for whom these documents are supposed to be guidelines expressed themselves in these matters. Monoculturalism can be described as a static perspective laid upon culture which emphasises cultural purity. A multicultural society describes a society were the nation consists of many different cultures alongside each other, without a genuinely common core.
Hälsa på webben. Utvärdering av interaktiva svenska hälsosajter för allmänheten.
Health on the Internet is a growing subject and many different organisations and companies offer customers various kinds of medical functions on the web. A common service is to offer users to ask questions and get answers from doctors cooperating with the health sites. There is however little knowledge of how much the health sites actually are used, and by whom. Several authorities and organisations both in Sweden, Europe and in the USA are investigating whether it is necessary to bring forward a certificating authority with the right to judge and examine all the health sites on the web. WHO, the World Health Organisation, proposed a solution for this, which was refused.
Kontrollerad vokabulär eller naturligt språk? En empirisk studie.
The question whether controlled vocabulary or natural language free-text terms is the most effective search strategy has occupied researchers in LIS for many decades. This Masters thesis is an empirical study which aims to compare these two search strategies in LISA Library and Information Science Abstracts, an online bibliographic database. 22 topics from the discipline of Library and Information Science were constructed and out of each topic one query for each search strategy was formed. Queries in natural language were formed with terms from different sources, for example dictionaries, while queries in controlled vocabulary were built with terms from LISAs electronic thesaurus. The measures used in this study were precision, relative recall pooling method and overlap.
Globala och lokala sökmotorer: en utvärdering av Google, MSNSearch och Svesök
The purpose of this thesis is to evaluate three search engines with regard to retrieval effectiveness of information specific to Swedish users. Coverage and the precision in result descriptions are also examined. The three selected search engines are Google, MSN Search and Svesök. 30 queries were tested against the search engines and the first 20 result descriptions and results were judged for relevancy. Relevancy was judged by a binary scale.
Ämnessökningar med kontrollerad vokabulär och naturligt språk: en jämförande studie med felanalys.
The aim of this thesis is to compare the effectivity of using a natural language and a controlled vocabulary when performing subject searches in the bibliographic database LISA Library and Information Science Abstracts. 20 topics were created and for each topic two searches were made, one by using a query formulated with natural language directed to the abstract field and the other one by using a query formulated with descriptors from the thesaurus in LISA directed to the descriptor field. The average relative recall amounted to 64,8% for the AB-queries and 54% for the DE-queries. Failure analysis showed that the majority of the relevant documents not retrieved by AB-queries could have been retrieved with other query terms, such as synonyms. In a natural language there are many different ways of expressing a topic, and this tends to have a negative effect on retrieval effectivity.
Gratis pengar? - om sponsring av kultur
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.
