  1. 21. Extracting Transaction Information from Financial Press Releases

    Master-uppsats, Linköpings universitet/Artificiell intelligens och integrerade datorsystem

    Författare :Agaton Sjöberg; [2021]
    Nyckelord :Natural Language Processing; Information Extraction; Named Entity Recognition; Relation Extraction; Latent Structure Refinement; Financial Press Release; Insider Transaction;

    Sammanfattning : The use cases of Information Extraction (IE) are more or less endless, often consisting of a combination of Named Entity Recognition (NER) and Relation Extraction (RE). One use case of IE is the extraction of transaction information from Norwegian insider transaction Press Releases (PRs), where a transaction consists of at most four entities: the name of the owner performing the transaction, the number of shares transferred, the transaction date, and the price of the shares bought or sold.

  2. 22. Named-entity recognition with BERT for anonymization of medical records

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Olle Bridal; [2021]
    Nyckelord :NLP; anonymization; de-identification; NER; BERT; medical records; Swedish;

    Sammanfattning : Sharing data is an important part of the progress of science in many fields. In the largely deep learning dominated field of natural language processing, textual resources are in high demand. In certain domains, such as that of medical records, the sharing of data is limited by ethical and legal restrictions and therefore requires anonymization. LÄS MER

  5. 25. Named Entity Recognition för Klassificering av Rubriker i Fakturor

    Kandidat-uppsats,

    Författare :Ludvig Karlsson; Benjamin Gyllström; [2021]
    Nyckelord :Named Entity Recognition; Machine Learning; Invoice; Natural Language Processing; Header.; Named Entity Recognition; Maskininlärning; Faktura; Naturlig Språkbehandling; Rubrik.;

    Sammanfattning : Fakturor är en viktig källa av information för företag. Två exempel på viktiga fält i en faktura kan vara, hur mycket pengar som ska betalas och faktura id. På grund av olika format och innehåll i fakturor som skiljer sig åt är extraktionen av information från dessa fakturor ofta en manuell process som kräver mycket tid. LÄS MER
