    Nyckelord :natural language processing; machine learning; multi label text classification; deep neural networks; bilingual texts; emails; short texts;

    Sammanfattning : This master’s thesis studies a multi label text classification task on a small dataset of bilingual, English and Swedish, short texts (emails). Specifically, the size ofthe data set is 5800 emails and those emails are distributed among 107 classes withthe special case that the majority of the emails includes the two languages at thesame time.

  3. 3. The challenge of data-driven requirements elicitation techniques : Systematic Literature Review & Controlled Experiment

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för programvaruteknik; Blekinge Tekniska Högskola/Institutionen för programvaruteknik

    Författare :Tianpeng Zhang; Linxiang Ruan; [2020]
    Nyckelord :Requirements Elicitation; Data-Driven Requirements; Social Network Analysis; Text Classification;

    Sammanfattning : Background. Nowadays, Requirements Engineering(RE) focuses not only the pri- mary stakeholders but also large scale data, which comes from an amount of cus- tomers’ operations and feedback. For instance, the user reviews in the mobile app platform become an important analysis target, since they contain a lot of informa- tion. LÄS MER

  4. 4. Automatic language identification of short texts

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Anna Avenberg; [2020]
    Nyckelord :Automatic language identification; Natural language processing; Machine learning; Artificial intelligence; Short texts;

    Sammanfattning : The world is growing more connected through the use of online communication, exposing software and humans to all the world's languages. While devices are able to understand and share the raw data between themselves and with humans, the information itself is not expressed in a monolithic format. LÄS MER

  5. 5. Evaluation of text classification techniques for log file classification

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Per Olin; [2020]
    Nyckelord :Text classification; machine learning; NLP; natural language processing; log file; doc2vec; CNN; LSTM; LSTM-CNN;

    Sammanfattning : System log files are filled with logged events, status codes, and other messages. By analyzing the log files, the systems current state can be determined, and find out if something during its execution went wrong. LÄS MER
