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.

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.

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.

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.

Aim: The purpose of this paper is to see if there has been a change over time in the performance and in the spoken word of the Swedish cooking programs. By testing the theory of intimization on the cooking programs I get the opportunity to see if the border between the private and the public have become clearer or more difficult to notice, and if the new language, the informal language as intimization entails, has been used in Swedish cooking programs since the 70s until today, or if there´s ever been a formal language in Swedish programs? Method/Material: I'm using a rhetorical approach that includes a three-step analysis. Analysing the context, means to persuade and performance. The empirical material I intend to analyze is Swedish cooking programs from the 70s until today, 2010.

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.

The theses discuss information seeking with a focus on Google and social networks. Students attending the librarian program in Lund have been examined by means of two methods; diaries and information horizons, where they had to solve a specific assignment. The information horizon as a method contributes to getting a structural perspective on the information search process instead of viewing information search as a procedure. Information horizons use social network analysis.The aim of the theses is to investigate the importance of the social network in information search, with a particular focus on Google as a search tool. Our hypothesis is that Google acts as a compensator to the social network when the students search for information and in the educational program.The research indicates that there is no direct correlation between usage of the social network and usage of Google.

EPiServer is a content management system where users can publish information on a website by using a web browser. EPiServer has a built-in search engine that is very simple. 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.

In November 2010, The Swedish Association of Local Authorities and Regions (Sveriges Kommuner och Landsting) distributed a survey where 53 % of the responding municipalities declared that they use Twitter. Out of the municipalities that declared they did not use social media, 49 % answered that they were planning on using it but that they had not gotten started. The purpose with social media was primarily declared to be maintaining dialogue with citizens and a channel for information.The informal ?twittersphere? is a new environment for the conventionally formal government communication, and with it comes an entirely new set of demands on the style and content of texts, compared to other media. The purpose of my work was to present a style proposal for the public sector?s communication on Twitter, with the help of theory and empirical data.My methods consisted of text analysis and qualitative interviews.

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 paper is a comparing study of the retrieval effectiveness of the search engines Google, Google Scholar and Scirus. The aim is to find out how good they are at retrieving relevant academic material in the research-field of Library and Information science. The thirty search questions where based on actual information needs collected from exams within the field of Library and Information Science. This method was used to prevent that none of the search engines were given an advantage because of construction of the information needs. The first twenty retrieved documents on the retrieval lists are examined for academic content and relevance.
