  2. 1. Everyday mining : Exploring sequences in event-based data

    University dissertation from Norrköping : Linköping University Electronic Press

    Author : Katerina Vrotsou; Linköpings universitet.; Linköpings universitet.; [2010]
    Keywords : TEKNIKVETENSKAP; TECHNOLOGY; Event-based data; activity diary data; event-sequences; interactive exploration; sequence identification; visual data mining;

    Abstract : Event-based data are encountered daily in many disciplines and are used for various purposes. They are collections of ordered sequences of events where each event has a start time and a duration. READ MORE

  4. 2. Mining Web Logs to Improve User Experience in Web Search

    University dissertation from Chalmers University of Technology

    Author : Libertad Tansini; Chalmers tekniska högskola.; Chalmers University of Technology.; [2008]
    Keywords : TEKNIKVETENSKAP; TECHNOLOGY; Web log mining; web search; user recommendation; user intent; user modelling;

    Abstract : The World Wide Web continues to grow in size and diversity and this makes it increasingly hard for users to find valuable information because of heterogeneous form and content of the documents, little knowledge about the reliability and prestige of the documents and a great deal of redundancy. Usually search engines look for documents that contain specific keywords or phrases stated by the users as queries. READ MORE

  5. 3. Finding, extracting and exploiting structure in text and hypertext

    University dissertation from Umeå : Umeå Universitet

    Author : Ola Ågren; Umeå universitet.; [2009]
    Keywords : TEKNIKVETENSKAP; TECHNOLOGY; Automatic propagation; CHiC; Data mining; Discrete data; Extraction; Hierarchies; ProT; Rank distribution; S²ProT; Spatial linking; Web mining; Web searching; Computing Science; administrativ databehandling;

    Abstract : Data mining is a fast-developing field of study, using computations to either predict or describe large amounts of data. The increase in data produced each year goes hand in hand with this, requiring algorithms that are more and more efficient in order to find interesting information within a given time. READ MORE

  6. 4. Data mining and analysis for characterizing paper from online multisensor measurements

    University dissertation from Chalmers University of Technology

    Author : Marcus Ejnarsson; Chalmers tekniska högskola.; Chalmers University of Technology.; Högskolan Halmstad.; [2008]
    Keywords : TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY; Feature Extraction; Kernel Based Novelty Detection; Kernel CCA; Monitoring; Newsprint; Paper Web; Time-Series Representation;

    Abstract : The objective of this thesis is to develop a multi-resolution tool for screening paper formation variations, aiming to detect abnormalities in various frequency regions ranging from millimeters to several meters. The abnormalities detected in different frequency regions give an indication for the paper maker about specific disturbances in the paper production process. READ MORE

  7. 5. Patch loading resistance of longitudinally stiffened steel girder webs

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Carlos Graciano; Luleå tekniska universitet.; Luleå University of Technology.; [2002]
    Keywords : ;

    Abstract : In most cases, longitudinal stiffeners increase the resistance of steel girder webs subjected to concentrated forces, commonly referred to as patch loading. During the last three decades, a number of experimental investigations have been undertaken in all over the world in this regard. READ MORE
