    Sammanfattning : Geographic information is one of the most important and the most common types of information in human society. It is estimated that more than 70% of all information in the world has some kind of geographic features. LÄS MER

  3. 2. Subject retrieval in web-based library catalogs

    Författare :Koraljka Golub; Jadranka Lasić-Lazić; Department of Information Science Filozofski fakultet u Zagrebu; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; British university libraries; Croatian university libraries; Indexing and retrieval systems; Online library catalogs; Subject access points; Subject retrieval; User interface; User search behavior; WebPACs; Library and Information Science; Biblioteks- och informationsvetenskap;

    Sammanfattning : This thesis has been motivated by past research, problems and realizations that online library catalog users frequently perform subject searches – using keywords, subject headings and descriptors – and these searches have yielded unsatisfactory results. Web-based catalogs or WebPACs (Web-based Online Public Access Catalogs), belonging to the so-called third generation of online catalogs and providing a wide variety of search options, remain largely underutilized despite the continuous advancement of information retrieval systems.

  4. 3. Trust-Based User Profiling

    Författare :Nima Dokoohaki; Mihhail Matskin; Vlad Vlassov; Felix Wu; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; trust; userprofiling; userprofiles; privacy; interest; socialnetwork; recommendersystems;

    Sammanfattning : We have introduced the notion of user profiling with trust, as a solution to theproblem of uncertainty and unmanageable exposure of personal data duringaccess, retrieval and consumption by web applications. Our solution sug-gests explicit modeling of trust and embedding trust metrics and mechanismswithin very fabric of user profiles. LÄS MER
