    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Elias Johansson; [2024]
    Nyckelord :Tunnel water; tunnel construction; nitrogen; fertilizer; irrigation; Länshållningsvatten; Tunnelvatten; Tunneldrivning; Kvävegödsel; Bevattning;

    Sammanfattning : When a tunnel is built in rock, a type of water is formed as a residual product. This tunnel wateris formed due to construction processes such as drilling requiring water and groundwater thatinfiltrates into the tunnel. The water can cause environmental damage if it is released directlyinto nature and needs to be treated. LÄS MER

  3. 2. Comparison of VADER and Pre-Trained RoBERTa: A Sentiment Analysis Application

    Kandidat-uppsats, Lunds universitet/Statistiska institutionen

    Författare :Linda Erwe; Xin Wang; [2024]
    Nyckelord :sentiment analysis; natural language processing; BERT; VADER; sustainability report; Mathematics and Statistics;

    Sammanfattning : Purpose: The purpose of this study is to examine how the overall sentiment results from VADER and a pre-trained RoBERTa model differ. The study investigates potential differences in terms of the median and shape of the two distributions. Data: The sustainability reports of 50 independent random companies are selected as the sample.

  5. 4. IŻ SWÓJ JĘZYK MAJĄ! An exploration of the computational methods for identifying language variation in Polish

    Master-uppsats, Göteborgs universitet / Institutionen för filosofi, lingvistik och vetenskapsteori

    Författare :Maria Irena Szawerna; [2023-06-19]
    Nyckelord :language variation; Polish; diachronic linguistics; part-of-speech tagging; lemmatization; corpus linguistics;

    Sammanfattning : Computational approaches to language variation continue to contribute in a relevant way to various fields, including Natural Language Processing (NLP) and linguistics. Being able to accommodate variation within natural language increases the robustness of NLP models and their usefulness in real-life applications; simultaneously, detecting and describing variation and trends that govern it is one of the main goals of sociolinguistics and historical linguistics, meaning that some of the advances in NLP can contribute to these fields as well.
