1	Google, Yahoo! och Live Search : en evaluering av tre webbsöktjänster / Google, Yahoo! and Live Search : an evaluation of three Web search engines Jogehed, Pernilla January 2007 (has links) 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. For every search the first 10 hits in each of the three search engines were evaluated. The measures that have been used are precision and overlap. The queries were evaluated on a binary relevance scale with 0 or 1. Precision has been measured as average precision over 1-10 DCV levels for all 20 queries in the evaluation. It has also been measured as average precision in a query-by-query calculation over 10 DCV levels for each query and search engine. The number of duplicate links, dead links, mirror pages, relevant hits and irrelevant hits has also been recorded in the study for each search engine, for a comparison. Overlap was measured at two different DCVs, 1 and 5. Eventually the results show that Google had the best results regarding precision. It also had the highest number of relevant hits. Google and Yahoo! showed the highest overlap at DCV 1. At DCV 5 the greatest overlap was between Yahoo! and Live Search. / Uppsatsnivå: D information retrieval relevans precision google yahoo! live search evaluering söktjänster Social Sciences Samhällsvetenskap
2	Visualization of live search / Visualisering av realtidssök Nilsson, Olof January 2013 (has links) The classical search engine result page is used for many interactions with search results. While these are effective at communicating relevance, they do not present the context well. By giving the user an overview in the form of a spatialized display, in a domain that has a physical analog that the user is familiar with, context should become pre-attentive and obvious to the user. A prototype has been built that takes public medical information articles and assigns these to parts of the human body. The articles are indexed and made searchable. A visualization presents the coverage of a query on the human body and allows the user to interact with it to explore the results. Through usage cases the function and utility of the approach is shown. search technology search engine information retrieval live search query completion facet recall precision machine learning document classification linear classifier document categorization document clustering multi-label classification labelling hamming loss f-score visualization information visualization distance-similarity metaphor spatialized display visual information-seeking mantra user interface spatialization document processing Interaction Technologies Interaktionsteknik Computer Sciences Datavetenskap (datalogi) Information Systems Human Computer Interaction
