  1. 1. Monolingual and Cross-Lingual Survey Response Annotation

    Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

    Författare :Yahui Zhao; [2023]
    Nyckelord :transfer learning; zero-shot cross-lingual transfer; model-based transfer; multilingual pre-trained language models; sequence labeling; open-ended questions; democracy;

    Sammanfattning : Multilingual natural language processing (NLP) is increasingly recognized for its potential in processing diverse text-type data, including those from social media, reviews, and technical reports. Multilingual language models like mBERT and XLM-RoBERTa (XLM-R) play a pivotal role in multilingual NLP. LÄS MER

  3. 2. Real-time unsupervised log event anomaly detection in public transportation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Felicia Segui; Andreas Timürtas; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Detecting log data anomalies in real-time is useful since it makes it possible to apply logic that corrects the anomalies when they happen. This project presents a method for detecting public transportation bus event log data anomalies in realtime, without having a labeled data set. LÄS MER

  4. 3. Assessment of the Capability for Vetoing Beta-Decay Events in the Lundium Decay Station

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Tanvir Sayed; [2022]
    Nyckelord :Radioactivity; Decays; Radiation; Ionisation; Superheavies; Exotic isotopes; Decay spectroscopy; Semiconductors; Silicon-Strip Detectors; Lundium; Vetoing; Electron spread; Particle identification; Physics and Astronomy;

    Sammanfattning : Alpha decay spectroscopy using the latest and most sensitive detector setup as well as fast sampling read-out electronics has become very important for discovery and analysis of short-lived nuclei created in collision experiments in the laboratory. The Nuclear Structure Group in Lund is currently developing the Lundium Decay Station for use in comprehensive nuclear spectroscopy of decays for rare isotopes, particularly in the heavy & superheavy region.

  5. 4. Extracting Salient Named Entities from Financial News Articles

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :David Grönberg; [2021]
    Nyckelord :named entity recognition; named entity linking; natural language processing;

    Sammanfattning : This thesis explores approaches for extracting company mentions from financial newsarticles that carry a central role in the news. The thesis introduces the task of salient named entity extraction (SNEE): extract all salient named entity mentions in a text document. LÄS MER

  7. 5. A study of the photochromic effect in oxygen containing rare-earth metal hydride thin films and multilayer structures

    Master-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Sigurbjörn Már Aðalsteinsson; [2020]
    Nyckelord :;

    Sammanfattning : In this work, we have studied the photochromic response of several oxygen containing rare-earth hydride thin films (REHO, RE = Y, Nd, Gd, and Dy). Their chemical composition was characterized by an iterative multi-method approach based on ion beams, while the photochromic effect was measured by means of optical spectrometry. LÄS MER
