Att söka samhällsinformation. En användarundersökning
Citizenship information is defined as the information the citizen needs to be able to take part in and influence the society. Since it is a democratic issue that information concerning the citizens role in society really reaches the citizens, it is of importance to study how the citizens proceed when they have a need for this information. The aim of this Masters thesis is to investigate how our eight informers proceed when they experience this need in a non-work situation. We performed qualitative interviews. The most important part of our interviews was the introduction of some fictitious problems to the informants.
Icke-triviala billigaste väg-ruttningskonflikter - klassificering och sökmetoder
Within telecommunication and routing of tra?c in IP-networks a protocol named?Open Shortest Path First? (OSPF) is widely used. This means that a server dealswith the routing over a network with given weights by calculating shortest paths touse for routing. If we assume that a desired tra?c pattern is given the problem isto ?nd out if it is possible to set the weights so that the desired tra?c pattern is apart of a shortest path graph.
Återvinning av skönlitteratur - Återvinningsverktygens anpassning efter användares sökbeteenden : En fallstudie på Trelleborgs bibliotek
Traditionally the content of fiction has not been described, analyzed, classified and/or indexed to the same extent as non-fiction. As a consequence, this lack of content analysis has resulted in unsatisfactory fiction retrieval in relation to users seeking and search behaviour. This fact is why this Master s thesis is written. The total of library users' seeking and search behaviour is investigated in order to suggest methods to improve user adapted fiction retrieval tools. Suggesting relevant fiction retrieval tools corresponding to users' seeking/search behaviour is another aim of the study.
Klassifikation på webben
The thesis concerns the use of classification schemes for organising resources in subject-based hierarchical search-services on the web. The aim is to investigate the different kinds of classification that are used, which fall into two groups: established respectively new classification schemes. This is attained by studying literature and the websites of each search-service. The prospects for using classification in a web-environment are discussed and divided into three major groups: browsing, control and cross-classification. One question at issue concerns how an established scheme manages to organise web-resources and whether this classification differs from the classification of new schemes and in what way.
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.

att synas på internet - ett praktiskt företagsperspektiv
Today Internet is clogged up and packed with homepages and information from both private persons and commercial companies. This has led to a decreased availability for a company to be noticed. The most common tool for consumers to use while searching for products online is via search engines. But because of the nature of these, not all companies can have good placements. Our research question was, "How do small online-companies attract consumers to their website"? The purpose of this thesis is to identify how a company works through online-communications and how to attract consumers to their home page.

The aim of this master thesis is to study the students usage and experiences of the reference services at the university library at Linköping University.

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.
