11. Sentence Embeddings and Automatic Classification of Menu Items
Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : Caspeco AB is a company in Uppsala that specializes in providing IT solutions to the hospitality industry. Their customers (restaurants, pubs, etc.) classify their menu items freely, which leads to a classification that is often inconsistent and unreliable. LÄS MER
12. Methods for increasing cohesion in automatically extracted summaries of Swedish news articles : Using and extending multilingual sentence transformers in the data-processing stage of training BERT models for extractive text summarization
Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskapSammanfattning : Developments in deep learning and machine learning overall has created a plethora of opportunities for easier training of automatic text summarization (ATS) models for producing summaries with higher quality. ATS can be split into extractive and abstractive tasks; extractive models extract sentences from the original text to create summaries. LÄS MER
13. Automated Trouble Report Labeling : In The Telecom Industry
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : Trouble reporting is a substantial component in any technical product's maintenance workflow. In this project, we investigated a set of methods for streamlining this workflow, using both software solutions and machine learning. The aim was to find a way of grouping trouble reports for easier analysis and other potential usecases down the line. LÄS MER
14. Optimizing the Performance of Text Classification Models by Improving the Isotropy of the Embeddings using a Joint Loss Function
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Recent studies show that the spatial distribution of the sentence representations generated from pre-trained language models is highly anisotropic, meaning that the representations are not uniformly distributed among the directions of the embedding space. Thus, the expressiveness of the embedding space is limited, as the embeddings are less distinguishable and less diverse. LÄS MER
15. Improving BERTScore for Machine Translation Evaluation Through Contrastive Learning
Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologiSammanfattning : Since the advent of automatic evaluation, tasks within Natural Language Processing (NLP), including Machine Translation, have been able to better utilize both time and labor resources. Later, multilingual pre-trained models (MLMs)have uplifted many languages’ capacity to participate in NLP research. LÄS MER
