This paper is a literature study on search engine optimization (SEO) considering the leader of the search engine market: Google. There´s an introductory background description of Google and its methods of  crawling the Internet and indexing the web pages, along with a brief review of the famous PageRank algorithm. The purpose of this paper is to describe the major important methods for improved rankings on Google´s result lists. These methods could be categorized as on-page methods tied to the website to be optimized or off-page methods that are external to the website such as link development. Furthermore the most common unethical methods are described, known as ?black hat?, which is the secondary purpose of the text.

The purpose of this thesis is to evaluate two pearl growing methods in ISI Web of Science. The methods tested are Find Related Records FRR, an automatic service that uses bibliographic coupling, and Author Keywords AK, where searches are performed using the two first keywords from this field. Both search methods were used on twenty initial documents and the first twenty hits were evaluated for relevance using a binary scale 0,1. The relevance criteria were based on specific information needs connected to every initial document. The measures used to evaluate the effectiveness of the search methods were Precision at DCV=10, P10, and Uninterpolated Average Precision AP.

Millions of people are using search engines every day when they are trying to find information on the Internet. The purpose of this report is to find out how people formulate search queries. The result in this report is based on an empirical study which is based on a search log from the Swedish search engine Seek.se.One of the results in this thesis is that nearly all search queries are based on keywords..

This thesis is a case study of the informal internal communication at a Swedish government agency called Swedac. The purpose of the study was to investigate how the employees perceive and use the informal internal communication, what communication media they utilize for it and how the informal internal communication correlates to certain aspects of the organizational structure. In order to achieve this, six qualitative interviews was carried out with employees in the organization. Since informal internal communication is not a well-defined concept I explained my view of the concept in the thesis. The results show that the informal internal communication is very important and fairly widespread at Swedac.

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.

The theoretical focus in this master is information retrieval (IR), and especially the part of IR that includes interactivity. This research is by some researchers called IIR. Our principal aim was to examine if search engines on the WWW are taking advantage of research results from IIR research. A way to do this is to look at the application of special features, in this case query expansion (QE) and relevance feedback (RF). Both these methods aim for a better matching of documents and the searchers information need.

The purpose of this essay is to perform an evaluation regarding retrieval performance of three web search engines. The search engines included are All the Web, Alta Vista and Google. These have been tested using ten queries within different subject areas chosen by the author. The first twenty hits for each question have been analyzed for relevancy. Relevancy is judged on a three-point scale; 0, 0,5 and 1 where 0 goes to irrelevant and inactive or duplicate documents, 0,5 point goes to partially relevant documents and 1 point goes to highly relevant documents.

The purpose of this thesis is to analyse studies that evaluate Web search engines. This is done in four categories; the researchers? purpose, the evaluation measurements, the relevance, and the time aspect. Our method is based on a text analysis in which we use the direction of analysis of the content of sixteen evaluation experiments. Our results indicate fundamental differences in the way the researchers are tackling the problem of evaluation of Web search engines.

The aim of this thesis was to investigate how teachers in school and in leisure time center look at informal and formal learning. Informal learning is often associated with leisure-time while formal learning is generally linked to school. My questions also deal with the teachers? view of each other?s activities from a learning perspective and visibility of informal learning. I have made an empirical study with qualitative, semi-structured interviews with three class teachers and three leisure teachers.

This thesis aims at studying representatives from three groups in the Egyptian society with an ethnographic method and with regards to their experiences, reflections and stories of the Egyptian revolution. The material of the thesis is based on ethnographic fieldwork and on interviews.The purpose of the study is to explore different themes in the informants? stories related to society, freedom, social justice, human values, peace and civility. The purpose is also to examine the informants' stories with emphasis on various informal learning processes that occurred in the Egyptian social change.The study finds that according to the informants a society should be characterized, among other things, by human values, social justice, non-violence and peaceful methods and approaches. Various informal learning processes involving both individual citizens and active members of civil society and NGO groups were found to be practiced to be able to accomplish these changes in the Egyptian society to create a better future.The degrees of involvement of the various learning processes not only reflect differences between informants regarding the social and cultural background.

Background: Learning is important for companies? existence in today?s society and many studies discuss the importance of life long learning and learning organizations. An increased understanding for how the individual learn at the work place is importance to study to gain an accepting for how learning occurs, both formal and informal. Purpose: The purpose with this study is to describe the process of learning at the work place from an individual perspective, with focus on how formal and informal learning occur and interact. The purpose is also to confirm, contradict or develop existing theories.

Abstract The increased focus on social capital theory has made its way into labour economics. This has led to the creation of a vast literature about the use of networks and Informal search methods in the labour-market, a literature that to some extent also deals with immigrants search behaviour and their relatively high unemployment rate. Characteristic for the literature in the area is the lack of analysis of actual networks. Which types of contacts do these networks contain; how are the networks used in the labour-market; and which type of network generates a high amount of social capital. These questions are important for the general understanding of how social capital functions, within the labour-market, but also for the understanding of how immigrants use their networks in order to find themselves jobs.

The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.
