  1. 1. Topical Classification of Images in Wikipedia : Development of topical classification models followed by a study of the visual content of Wikipedia

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Matheus Vieira Bernat; [2023]
    Nyckelord :Wikipedia; Multilabel classification; Deep learning;

    Sammanfattning : With over 53 million articles and 11 million images, Wikipedia is the greatest encyclopedia in history. The number of users is equally significant, with daily views surpassing 1 billion. Such an enormous system needs automation of tasks to make it possible for the volunteers to maintain. LÄS MER

  4. 3. Knowledge dissemination from and knowledge production of a public review digital information source : A snapshot of visitors and active users’ activity in two language versions of Wikipedia

    Magister-uppsats, Linnéuniversitetet/Institutionen för kulturvetenskaper (KV)

    Författare :ELLI HADJIGEORGIOU; [2022]
    Nyckelord :Wikipedia; Wikipedians Wiks ; DESN; knowledge generation and public content review;

    Sammanfattning : During the last two decades, Wikipedia’s multiple language versions managed to become editable forms of knowledge source, publicly available, which deal both, with non-typical knowledge dissemination and knowledge production, thanks to visitors’ viewership and active users/Wikipedians visitation/viewership and voluntary contribution, respectively. This dissertation investigates the function of recent viewership and editing in Wikipedia in Greek (WiG) and Bulgarian Language (WiB), by visitors and active users/Wikipedians (G-Wiks and B-Wiks), respectively, with respect to the issue of knowledge production (including reproduction) in the broader spectrum of Epistemology.

    Författare :Drew Perkins; [2020]
    Nyckelord :language; technology;

    Sammanfattning : In this study, I constructed a named-entity linking system that maps between contextual word embeddings and knowledge graph embeddings to predict correct entities. To establish a named-entity linking system, I first applied named-entity recognition to identify the entities of interest. LÄS MER

  7. 5. AUTOMATED OPTIMAL FORECASTING OF UNIVARIATE MONITORING PROCESSES : Employing a novel optimal forecast methodology to define four classes of forecast approaches and testing them on real-life monitoring processes

    Master-uppsats, Umeå universitet/Institutionen för matematik och matematisk statistik
