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.

Bildförbättring över en bildsekvens

When SKL (Swedish National Laboratory of Forensic Science) gets images to analyse, the task often is to identify a person or an object. In that work it?s important to find features. Unfortunately images from camera surveillances often contain a lot of noise, so details can be hard to discern.A simple method to improve an image from a sequence is to compute the mean of some of the images. However, the part of interest in the image has to be in the same position in all images.

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.

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).

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.

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.
