    Sammanfattning : Natural language processing (NLP) is a vibrant area of research with many practical applications today like sentiment analyses, text labeling, questioning an- swering, machine translation and automatic text summarizing. At the moment, research is mainly focused on the English language, although many other lan- guages are trying to catch up. LÄS MER

  3. 3. Suitability of OCR Engines in Information Extraction Systems : a Comparative Evaluation

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Zacharias Erlandsson; [2019]
    Nyckelord :;

    Sammanfattning : Previous research has compared the performance of OCR (optical character recognition) engines strictly for character recognition purposes. However, comparisons of OCR engines and their suitability as an intermediate tool for information extraction systems has not previously been examined thoroughly. LÄS MER

  4. 4. Comparison of sequence classification techniques with BERT for named entity recognition

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Erik Rosvall; [2019]
    Nyckelord :;

    Sammanfattning : This thesis takes its starting point from the recent advances in Natural Language Processing being developed upon the Transformer model. One of the significant developments recently was the release of a deep bidirectional encoder called BERT that broke several state of the art results at its release. LÄS MER
