Nyhetssöktjänster på webben: En utvärdering av News Index, Excite News Search och Ananova
The purpose of this study is to examine the retrieval performance of three search engines, specialized in retrieving news articles: News Index, Excite News Search and Ananova. Thirty questions, grouped into three categories – politics, economy and sports, were used and the first twenty documents for each question were examined. The questions used were designed to be as current as possible and efforts were made to perform the searches with as little time span as possible between each search engine. The precision of the search engines was determined for each of the questions as well as for each category and for the combined categories. In measuring precision an average was calculated, intended to favour search engines that place its relevant documents early in the ranked list.

The evaluation is a preliminary investigation that may serve as a basis for a future more comprehensive evaluation. The four major questions for my thesis have been: 1. In which different ways can a user search? 2.
Växtdatabas med sökmotor :
My work has resulted in an interactive search engine for plants that can be found at www.plantit.se. In the work process I have searched for which search criteria is most important when doing searches on woodland plants. I have done this by an analysis of existing databases and with an survey where leading plant expertise answered questions about woodland plants.
I analyzed three search pages that are on the internet today Havenet.dk, Backyardgardener.com and Den virtuella floran. I concluded that there are several flaws but also many positive aspects that I have used when developing the interface of my page.
The survey resulted in the basis for my search criteria the answers listed the most important factors when planting woodland plants. From this information I developed a system with five values on every criteria.
Google Bilders användbarhet : Gränssnitt, sökfunktioner och återvinning
This essay explores to what extent the Swedish language version of Google Images meets the usability requirements of average everyday users. Previously published studies on user behaviour and users? interface and search option preferences define the usability requirements, which are matched against Google Images? actual interface and search options. The retrieval method of Google Images is also briefly discussed, and users? opinions about Google Images too, as they come across in the previously published user studies.The findings are that Google Images lack some of the things that users ask for, but it still seems to be the most used image search engine among average internet users and more appreciated than other search engines.
Att författa en Design- en processorienterad fallstudie av manusförfattandets arbetsprocess i ett interaktionasdesignarbete
This thesis is a process oriented case-study. The studied case is a interactiondesignassignment of a databasevisualisation and the process. The goalis to do this according to the ways of a screenwriter.When the computers spread from the military and university's into homes all around the world the computers and the programs had to becomeeasier for the users to understand and use. User interfacedesign became more and more important and companies like Apple put a lot of resources intothe designprocess. This quite new and evolving area of research, interactiondesign, has been forced to search for methods in other areas like lm, gamedesign, psychology and behavioural science.
Att göra det osynliga synligt : sökmotoroptimering (SEO) av en webbsajt
A webpage can be perfectly usable but if users are unable to find the webpage it will remain unused. Nine out of ten Swedes use a search engine and the most popular one is Google, amongst other search engines. In this report I seek to answer which ranking factors that should be included in an SEO-audit of an existing webpage and also how to optimize a webpage for search engines. Applying the method heuristic evaluation normally used to discover usability issues in an existing interface, on TT News Agency?s campaign site I found issues having a negative impact on the visibility in Search Engines Page Results.
Analys och kontroll av hållfasthet på grenställsarm
The thesis was done in collaboration with EAB situated in Smålandsstenar. In the initial discussion faze on doing a thesis with them there was a need to analyze and ensure the strength of an existing product, cantilever racks. This included performing FEM calculations on a model and comparing the results with physical tests.EAB has two models of cantilever racks, a light duty and a heavy duty. Within the heavy duty model series there are five product variants that differ in both size and load capacity. We will be working with the product variant with a load capacity of 1000 kg/arm which is the variant that is in the middle of the series.When we started work on the thesis we did a literature study and couldn?t find any well defined methodology that integrates both product development and computer aided design analysis.
Bestämning av osäkerheten hos skattningar av tyngdaccelerationen
In this master's thesis the problem of determining the uncertainty for an estimator of an unknown parameter is considered. The case we study is the estimation of gravity using a reversible pendulum. This involves the estimation of the point where two regression lines intersect. The estimated gravity is a function the coordinates of this point. One way to determine the uncertainty of this estimator is to use bootstrap methods.
Att hitta rätt: bibliotekariers utveckling av referensarbete
The aim of this Masters thesis is to understand how librarians develop their reference service. The purpose was to find patterns in how librarians work with reference questions. As a theoretical framework we have used research in the reference field. Where do the skills of the search process come from: education or experience? Answers were sought to the following questions: - How different are the search process in practice compared to theory? - Which similarities and differences are there among the informants? - How important was the education in comparison to the knowledge about the libraries collections? - How did the changes in the school system in 1993 influence reference education and what could the consequences be to the reference knowledge among librarians? We sent out a question form and a search question which was answered by 12 librarians in university and university college libraries.
Agila metoder ? en kartläggning av teori och praktik
In recent years, agile software development methods have become increasingly popular throughout the world. Today there are a number of different agile methods and they all rest on the Agile Manifesto that was formulated in 2001 as a reaction to the traditional software processes.The aim of this thesis is to make a survey of some of the agile methods used today and to see how they are being used in practice. It consists of two parts: a literature study and an interview study with people working in the software business. First, a definition of agile methods is proposed and a number of different agile methods are described. Second, the interviews are being analysed with special focus on communication, collaboration, expectations and results.

Söktjänster för akademiskt bruk: En utvärdering av Google och Argos med frågor från en akademisk ämnesdisciplin
The purpose of this MSc thesis is to examine the retrieval effectiveness of two Web search engines with queries from the academic discipline of Classical Studies. The two search engines are chosen to represent two different types Google as a broad general search engine and Argos as a specialised search engine for the subject of Classical Studies. The search engines are compared for precision among the first twenty results returned for thirty queries. In order to avoid bias in the study, the queries are based on real users' information needs. Due to the subjective character of the concept of relevance, the study is performed with five different experiments with five different definitions of relevance.
Att riskera sin världsbild : En uppsats om tolkning av retoriska objekt ur två individuella perspektiv
This paper discusses the relationship between rhetoric and hermeneutics. It is a studyconducted through a generative method where two different rhetoric students haveanalyzed three rhetorical objects and afterwards have compared their results and theninterpreted the differences and similarities. The purpose is to find what makes aninterpretation legitimate and plausible and what binds rhetoric and hermeneuticstogether through meta analysis. The study shows that doxa is a fundamental elementthat connects rhetoric to hermeneutics and that it is more relevant to discussintersubjectivity than legitimacy, which is harder to define and achieve. An importantresult is also that the dialogue in the interpretation process has been found to be acatalyst for new research findings and of increased knowledge..
