  1. 1. Data Segmentation Using NLP: Gender and Age

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för datalogi; Uppsala universitet/Avdelningen för datalogi

    Författare :Gustav Demmelmaier; Carl Westerberg; [2021]
    Nyckelord :Natural language processing; NLP; sentiment analysis; machine learning; demographics; demographic factors; gender; age; ethics;

    Sammanfattning : Natural language processing (NLP) opens the possibilities for a computer to read, decipher, and interpret human languages to eventually use it in ways that enable yet further understanding of the interaction and communication between the human and the computer. When appropriate data is available, NLP makes it possible to determine not only the sentiment information of a text but also information about the author behind an online post. LÄS MER

  3. 2. Evaluating the Trade-offs of Diversity-Based Test Prioritization: An Experiment

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Ranim Khojah; Chi Hong Chao; [2020-12-03]
    Nyckelord :Diversity-based testing; Test Case Prioritization; Natural Language Processing NLP ; Level of Testing LoT ;

    Sammanfattning : Different test prioritization techniquesdetect faults at earlier stages of test execution. To this end,Diversity-based techniques (DBT) have been cost-effective byprioritizing the most dissimilar test cases to maintain effectivenessand coverage with lower resources at different stages of thesoftware development life cycle, called levels of testing (LoT).

    Författare :Erik Lenas; [2020]
    Nyckelord :Machine Learning; Natural Language Processing; Relation Extraction; Named Entity Recognition; Coreference resolution; BERT; Maskininlärning; Natural Language Processing; Relationsextrahering; Named Entity Recognition; Coreference resolution; BERT;

    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
