Ämnesordsåtervinning av skönlitteratur: En intervjuundersökning av bibliotekariers erfarenheter
The aim of this thesis is to investigate librarians? experiences and opinions about a system for fiction retrieval based on the subject headings list Att indexera skönlitteratur. I want to know if librarians experience that subject headings searches for fiction literature are a good working tool, if there according to librarians are other resources and means that makes fiction available and searchable, and how they estimate the possibility of non-professionals to use subject headings for fiction retrieval. Six librarians at public libraries in Göteborg where interviewed. The interviews dealt with their work with fiction literature, their experiences of subject headings as a fiction retrieval tool, and with their contacts with patrons.
Fri passage och tomtplatsavgränsning : En studie av två länsstyrelsers överprövningsärenden av kommunala strandskyddsdispenser
Strandskyddet i Sverige är en del av allemansrätten som innebär att var och en har rätt att under ansvar färdas fritt i den svenska naturen, den rätten skyddas av strandskyddslagstiftning i miljöbalken. Dispens från förbuden i strandskyddslagstiftningen kan medges av kommunen. Strandskyddslagstiftningen har sedan 2009 fått nytt innehåll, bland annat att Länsstyrelsen är den myndighet som efter att kommunen medgett strandskyddsdispens granskar och i vissa fall överprövar dessa ärenden. En ny regel som ska säkerställa att fri passage ges vid tomtplatsbestämning infördes även 2009.Ett antal överprövningsärenden har studerats för att kunna analysera tillämpningen av bestämmelserna av tomtplats och fri passage. En litteraturstudie är tänkt att svara på om krav på fri passage förekommer i andra länder.
Skålgropar i Kronobergs län : - en diskussion om alternativt medvetandetillstånd och passageritualer i bronsålderssamhället
This thesis discusses South Scandinavian cup marks in general, and cup marks in Kronobergs County in particular. The question is whether the cup mark phenomena can be viewed as an ordinary family-based cult for a kind of everyday use, or more likely as a community passage ritual. The thesis also suggests that cup marks were made by ritual participants in, or in the process of trying to reach, an altered state of consciousness..
Musikwebb ? En evaluering av webbtjänstens återvinningseffektivitet
The aim of this thesis was to evaluate the music downloading service Musikwebb regarding its indexing and retrieval effectiveness. This was done by performing various kinds of search in the system. The outcome of these searches were then analysed according to the criteria specificity, precision, recall, exclusivity and authority control. The study showed that Musikwebb had several flaws regarding its retrieval effectiveness. The most prominent cases were the criteria exclusivity and specificity.
Att sjunga en fråga. En jämförelse av tre Query-by-Humming-system och deras användare.
The aim of this study was to compare the Query-by-Humming systems Midomi, Musicline and Tunebot regarding their retrieval effectiveness. The aim was to see if there were differences between the systems but also between the user groups common users, musicians and singers. Query-by-Humming system means that the user sings a tune that the system then use to find the right melody.To compare the systems and their users, queries where collected from the different user groups and replayed for the systems. Mean Reciprocal Rank and Friedman test was used to do the comparison.The results showed that the system did not achieve equivalent and that there were no difference between the user groups. The Mean Reciprocal Rank showed that the systems had very different retrieval effectiveness, where Midomi was the system with best result and Musicline with the lowest result..
Innehållsbaserad bildåtervinning med Haar-transformation
The purpose of this thesis is to evaluate 7 different search strategies for content-based image retrieval with respect to retrieval effectiveness. The strategies are based on different levels of resolution implemented by the Haar transformation. The result of the study shows an improvement in both mean average precision and mean recall in strategies based on lower levels of resolution..
Automatisk query expansion: en komparativ studie av olika strategier för termklustring baserade på lokal analys
Automatic query expansion has long been studied in information retrieval research as a technique that deals with the fundamental issue of word mismatch between query and document. The purpose of this thesis is to compare the retrieval effectiveness of different strategies for automatic query expansion. The strategies are based on local analysis of the corpus and use statistical information from the local document set to extract terms that suppose to adapt themselves to each individual search and therefore appear to be searchonyms to the index terms. The strategies compared are: association clusters, metric cluster and scalar cluster. Baseline queries of 24 topics are expanded using terms from the different clusters and searches are made.
Finnes: flata. Sökes: information. Om lesbiska, informationsbehov och ämnesbestämning av skönlitteratur.
The aim of this Masters thesis is, partly, to examine the information needs of lesbians: what discernable information needs they have, how they seek information and which information sources they use. The purpose is also to examine what part fiction plays regarding the information needs mentioned above and how fiction indexing could improve retrieval. The study is conducted through ten qualitative interviews with lesbians as well as through textual analysis. The theoretical framework includes queer theory and theory concerning information needs and uses. The results indicate that lesbians have evident information needs that mostly concern identity.
Cirkushallen i Alby
Cirkus Cirkörs gymnasieskola blir en ny publikvänlig byggnad, men en öppen passage för att få inblick i verksamheten och väcka nyfikenhet. Men relativt små medel omvandlas Cirkushallen till den givna huvudbyggnaden i området, och blir ett tydligt dragplåster för hela kulturbyn i Alby industriområde, med Subtopia, Kulturskolan, Filmbasen mm.För det utomstående är cirkus en lek. För den som tränar är det på fullaste allvar. Detta speglas i byggnadens utformning, då det öppna publika kontrasterar mot den stängda fokuserade träningen.En passage som gör byggnaden tillgänglig från två håll och utgör hjärtat i gymnasiets verksamheter. Här möts alla som tar byggnaden i anspråk..
OPAC i moderna kläder ? en kvalitativ studie om olika generationers informationssökningsvanor och förväntningar på informationsåtervinningssystem
The purpose of this bachelor thesis is to find out how information seeking habits and experiences of people in different generations affects their expectations on information retrieval systems like OPAC. Two OPACs are used, one web-OPAC and one mobile-OPAC. The following questions are asked: how can theories about information seeking behaviors explain why and in which way one seeks information? In which way does information seeking behaviors and habits affect the experience of OPAC? Which differences and/or similarities can be found between the web-OPAC and the mobile-OPAC? How does generational aspects affect experiences and preferences in an information seeking context? The theoretical framework of the thesis is information retrieval with several models about information-seeking/searching needs and behaviors. The empirical data contains interviews with nine people in different generations and protocols about two different OPACs.
Kompensatoriska strategier för ordmobiliseringssvårigheter vid Alzheimers sjukdom : En fallstudie med enspråkiga och flerspråkiga personer
Sweden is getting an aging population and with this comes an increase in neurodegenerative diseases such as Alzheimer?s disease (AD). Bilingualism is also on the rise and this may result in an increase of bilingual people suffering from AD. Due to the linguistic deterioration associated with the illness people with AD, bilingual and monolingual, will be an increasing patient group with speech and language pathologists (SLPs). Word retrieval difficulty is an early symptom of the disease and several strategies to compensate for this have been observed (e.g.
Aspects on cow traffic and management on farms with automatic milking
This thesis consists of four case studies. The objective is to find out how to get a well functioning cow traffic in an automatic milking system. Different technical and building solutions are analysed and some adjustments are proposed for the DeLaval herd management software.
Case study 1: Lactation chart comparison from traditional cow traffic and Feed First? cow traffic
Case study 2: Farm A - a study of the precedence passage and the cow traffic
Case study 3: Farm B ? an overview of the farm and their way of working
Case study 4: Key factors ? how can we judge how well a VMS farm is working?
Case study 1: Lactation chart comparison from traditional cow traffic and Feed First? cow traffic
In this survey data is analysed from before and after rebuilding to Feed First? cow traffic. Lactation
graphs are compared between traditional cow traffic and Feed First? cow traffic.
Query Expansion ? en jämförande studie av Automatisk Query Expansion med och utan relevans-feedback
In query expansion (QE) terms are added to an initial query in order to improve retrieval effectiveness. In this thesis we use QE in the sense that a reformulation of the query is done by deleting the terms in the initial query and instead replacing them with terms from the documents retrieved in the initial run. The aim of this thesis is to, in a experimental full text invironment, study and compare the retrieval result of two different query expansion strategies in relation to each other. The following questions are addressed by the study:
How do the two strategies perform in relation to each other regarding recall?
What may be causing the result?
Are the two strategies retrieving the same relevant documents?
Two strategies are designed to simulate a searcher using automatic query expansion (AQE) either with or without relevance feedback.
Där jag aldrig varit
The sites I visit turned into routines a long time ago. Everywhere someone has decided what should be there and what will not fit. I retreat into my daydreams, away from everyday life. A longing for something different, something wonderful. I decided to go where I've never been, searching for something unknown.
Migration losses of Atlantic salmon (Salmo salar L.) smolts at a hydropower station area in River Åbyälven, Northern Sweden : passage fates at a reservoir, a power house and a bypass structure
A large number of rivers in northern Sweden have hydropower developments that cause negative effects on both up- and downstream migrations of anadromous species like Atlantic salmon. So far, most attention has focused on the hindrances of adult fish during their upstream spawning migration. However, since turbines in power stations cause losses on downstream passing fish, the focus on negative effects on smolts has increased. The aim of this study was to compare three different causes of losses of salmon smolts passing downstream through a power station area in the flow-controlled River Åbyälven in northern Sweden.A total of 61 wild salmon smolts were caught and radio-tagged in the River Åbyälven during their downstream migration in June 2009. The salmon smolts were released at three locations, 1.1 km upstream from the power station, in the turbine intake and in the upper part of a fishway, acting both for up- and downstream fish passage.
