31	Využití metod dolování dat pro analýzu sociálních sítí / Using of Data Mining Method for Analysis of Social Networks Novosad, Andrej January 2013 (has links) Thesis discusses data mining the social media. It gives an introduction about the topic of data mining and possible mining methods. Thesis also explores social media and social networks, what are they able to offer and what problems do they bring. Three different APIs of three social networking sites are examined with their opportunities they provide for data mining. Techniques of text mining and document classification are explored. An implementation of a web application that mines data from social site Twitter using the algorithm SVM is being described. Implemented application is classifying tweets based on their text where classes represent tweets' continents of origin. Several experiments executed both in RapidMiner software and in implemented web application are then proposed and their results examined.
32	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
