The aim of this Master?s thesis is to examine the retrieval performance of two search engines, Yahoo! News and Sesam, specialized on indexing news articles in Swedish. Thirty search questions were used in this study, divided into three different categories: domestic news, amusement and sport. Precision has been calculated both for the 30 search questions as a total and for the three categories as well. Precision was calculated at every DCV-level and then divided with the number of search questions used, in an attempt to reach an average measure.

In this essay, a search strategy for citation index is studied. The strategy, which is essentially a citation cycle, starts with documents retrieved by a subject search, wherefrom new documents are identified following the network of citations backwards and forwards in time. Based on the theory of polyrepresentation, the strategy exploits overlaps between cognitively different interpretations of the same documents in order to automatically select references seed documents used as a starting point for the forward chaining. The purpose of the investigation is to evaluate the retrieval effectiveness of the search strategy and to find out whether the strategy can be used to expand a subject search with the help of the network of references in order to retrieve new relevant documents. Two questions are formulated: 1a.

Traditionellt utvärderas effekter av kognitiv träning med objektiva prestationsmått. Syftet med uppsatsen var att undersöka självskattad exekutiv funktion som ett alternativt mått för att utvärdera effekter av kognitiv träning. Som utfallsmått valdes The behavior rating inventory of executive functioning - self report (BRIEF-SR). Vidare användes blandad design med för- och eftermätning samt tre oberoende grupper. Gymnasieelever (n = 63) delades in i; aktiv träningsgrupp, aktiv placebogrupp och passiv kontrollgrupp.

The purpose with this essay is to evaluate the retrieval performance between Googles basic search and the advanced search functions. A secondary purpose is to evaluate the differences between the binary relevance scale and a 4- point scale. The basic search is defined as a search with two terms combined with the Boolean operator AND. The advanced search is based on search functions that are adequate to compare to the basic search. They are categorized as AND-searches, OR-searches, AND and OR-searches, exact phrase, and depending on where the terms occur on the page.

The purpose of this thesis is to examine how novices set about when they search for information. Marchionini's information-seeking model is the theoretical starting point, which is supplemented by theories of other specialists within the field, such as Chowdhury; Harter; Large, Tedd and Hartley. As method a questionnaire survey was used. The questionnaire was sent to 96 students at IHM Business School in Gothenburg and 57 questionnaires were returned. The results show among other things that the majority of the students used highly interactive search strategies, and they did not plan their search before they carried out the search.

Today, one of the foremost tools used by the library staff is the library catalogue search tools. It has come to our understanding that some library staff are dissatisfied with how the search tools works. The aim of this study is to illuminate the library staff's negative experiences of the search tools, and to present a basis for future discussion and development. To our help we have used a quantitative survey which were sent to library staff that used one of the two largest integrated library systems in Sweden, BOOK-IT and Mikromarc. The questions regarded the library staff's perception of a number of features in the search tools.

The purpose of this paper is to compare the three search engines Web of Science, Google Scholar and MEDLINE in regards of recovery efficiency and the overlap of relevant documents when it comes to information searching for academic purposes. Furthermore, it raises the question whether freely available search engines and licensed search engines are interchangeable with each other. The empirical data in this study were collected through searches conducted in the three search engines Web of Science, Google Scholar and MEDLINE. Twenty search queries were used and the first twenty retrieved documents for each query were examined for relevance using previously designed criteria. The documents were scored by a binary relevancy scale and thereafter a precision value for each search engine was calculated.

The purpose of this Master?s thesis is to evaluate three general query-based web search engines. The search engines chosen are Google, Yahoo! and Live Search. The topics, which where transformed into twenty queries, are based on real users? information needs, taken from an ask-a-question service.

This thesis is a case study of the search function on the University of Uppsala?s web site. The search function in this study was chosen since it exists on a large and complex web site and there were apparent lacks in the old version of the search function. The thesis highlights some of the problems that can appear in the development of a search function on a local site. One interesting find is that one of the most difficult issues is organizational and not technical.

Many customers using EPiServer web publishing system is in need of more functionality than is offered by EPiServer's built-in search engine. The purpose of this thesis is to develop additional functionality extends that the built-in search engine in EPiServer. The assignment was also to identify what need to be developed in order to give customers a better  opportunity to help their visitors find the right information on their website.Since this thesis was started in 2005, a number of commercial search engine productsentered  the market and it has become more common for companies to invest inthese products instead of using the simple search engine that's built into EPiServer.These products have many of the features that have been developed in this thesis.Another crucial difference between EPiServer?s built in engine and other products isthe method used to index content.

Chief executives and other persons in management positions are not applicable to the same protection system as other employees. Lagen om anställlningsskydd is not applicable for example.

The purpose of this thesis is to examine which factors influence librarians selection of electronic information sources, and to investigate whether librarians use of search strategies and search tactics changes depending on which information source they use. The electronic information sources are: online databases, Online Public Access Catalogues OPAC, World Wide Web, and CD-ROM databases. The theoretical framework is based on step 3 Select a source and step 4 Formulate a Query in Marchioninis information seeking model. The search strategies are divided into two categories: analytical and browsing strategies. In order to supplement the theoretical framework with empirical facts, 8 librarians were interviewed.

This is a master thesis from Uppsala University in collaboration with B Locket AB (more known as www.blocket.se). B Locket AB is a large ad-company from Sweden, located in Stockholm.Search engines on the market today are becoming more and more complex. When they were first introduced, they only had one function and that was to produce search results containing the string that the user had typed. Today, users want it to be able to spellcheck, produce more results and sort search results on specific fields as well. Preferably, all these features should not affect the performance as a whole.The reason to why these demands have come up is that users are getting more and more used to internet services as a whole and they want everything to be as easy as possible.The user ability has become a substantially more important area in the computer industry and this needs to be taken into account when it comes to B Locket AB and its search engine.
