  1. 1. Detection of insurance fraud using NLP and ML

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Rasmus Bäcklund; Hampus Öhman; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Machine-Learning can sometimes see things we as humans can not. In this thesis we evaluated three different Natural Language Procces-techniques: BERT, word2vec and linguistic analysis (UDPipe), on their performance in detecting insurance fraud based on transcribed audio from phone calls (referred to as audio data) and written text (referred to as text-form data), related to insurance claims.

  3. 2. Cross-Lingual and Genre-Supervised Parsing and Tagging for Low-Resource Spoken Data

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

    Författare :Iliana Fosteri; [2023]
    Nyckelord :dependency parsing; part-of-speech tagging; low-resource languages; transcribed speech; large language models; cross-lingual learning; transfer learning; multi-task learning; Universal Dependencies;

    Sammanfattning : Dealing with low-resource languages is a challenging task, because of the absence of sufficient data to train machine-learning models to make predictions on these languages. One way to deal with this problem is to use data from higher-resource languages, which enables the transfer of learning from these languages to the low-resource target ones. LÄS MER

  4. 3. Evaluating and comparing different key phrase-based web scraping methods for training domain-specific fasttext models

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

    Författare :Love Book; [2023]
    Nyckelord :Machine Learning; Natural Language Processing; Word2vec; fasttext; KeyBERT; Web scraping; Transformers; Embeddings.; Maskininlärning; språkteknologi; Word2vec; fasttext; KeyBERT; Webbskrapning; Transformatorer; Inbäddningar.;

    Sammanfattning : The demand for automation of simple tasks is constantly increasing. While some tasks are easy to automate because the logic is fixed and the process is streamlined, other tasks are harder because the performance of the task is heavily reliant on the judgment of a human expert.

  5. 4. Sentiment Analysis for Talent Attraction

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen; Lunds universitet/Statistiska institutionen

    Författare :Jelena Zec; [2023]
    Nyckelord :NLP; sentiment analysis; BERT; transformers; Business and Economics;

    Sammanfattning : The reputation of a company on employer review platforms can have a significant impact on its ability to attract talented workers. Companies use sentiment analysis to learn how their employer brand is perceived online. LÄS MER

  7. 5. GO BACK TO /R/CONSPIRACY: AN EXPLORATION OF METHODS FOR THE AUTOMATIC DETECTION OF AFFECTIVE POLARIZATION ON REDDIT

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

    Författare :Klara Båstedt; [2022-10-06]
    Nyckelord :affective polarization; covid-19; social media; Reddit; NLP;

    Sammanfattning : Affective polarization – the tendency to hold negative attitudes towards an out-group and biased, positive attitudes towards an in-group – is a hot topic in research and public debate. There are concerns that news media’s tendency to focus on political conflict rather than issues is causing polarization to increase, but researchers lack methods to automatically asses levels of polarization in online debates and correlate them with news articles.
