  1. 1. Constructing and representing a knowledge graph(KG) for Positive Energy Districts (PEDs)

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Mahtab Davari; [2023]
    Nyckelord :Knowledge graph; Positive Energy Districts PEDs ; longest path; Questions and Answers; Community Detection; Node Embedding; t-SNE plots; Edge Prediction;

    Sammanfattning : In recent years, knowledge graphs(KGs) have become essential tools for visualizing concepts and retrieving contextual information. However, constructing KGs for new and specialized domains like Positive Energy Districts (PEDs) presents unique challenges, particularly when dealing with unstructured texts and ambiguous concepts from academic articles.

  3. 2. Impact of the autoencoder-based FINTA tractogram filtering method on brain networks in subjects with Mild Cognitive Impairment

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Teodor Pstrusiński; [2023]
    Nyckelord :Tractography; Autoencoder; diffusion MRI; Filtering; Graph; Connectome; Traktografi; Autoencoder; diffusions MRT; Filtrering; Graf; Konnektom;

    Sammanfattning : Diffusion Magnetic Resonance Imaging (dMRI) is a method for measuring molecular diffusion in biological tissue microstructure. This information can be used to predict the location and orientation of white matter fibers in the brain, a process known as tractography. LÄS MER

  4. 3. A graph database implementation of an event recommender system

    M1-uppsats,

    Författare :Alexander Olsson; [2022]
    Nyckelord :Event; Recommender system; Neo4j; Graph database;

    Sammanfattning : The internet is larger than ever and so is the amount of information on the internet.The average user on the internet has next to endless possibilities and choices whichcan cause information overload. Companies have therefore developed systems toguide their users to find the right product or object in the form of recommendersystems. LÄS MER

  5. 4. Comparison of state-of-the-art Temporal Interaction Network methods in different settings : Novel models to predict temporal behavior

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

    Författare :Indre Tauroseviciute; [2021]
    Nyckelord :Recommendation systems; Neural Collaborative Filtering; RNN; Backpropagation; Comparative analysis;

    Sammanfattning : Recommendation systems become more and more necessary due to the growing supply chain. Therefore, scientists are developing models that can serve different recommendation needs faster than before, and it is getting more complicated to choose the model for a specific case. LÄS MER

  7. 5. Recommendation system for job coaches

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Nils Söderkvist; [2021]
    Nyckelord :database; graph; graph database; recommendation system; recommender system;

    Sammanfattning : For any unemployed person in Sweden that is looking for a job, the most common place they can turn to is the Swedish Public Employment Service, also known as Arbetsförmedlingen, where they can register to get help with the job search process. Occasionally, in order to land an employment, the person might require extra guidance and education, Arbetsförmedlingen outsource this education to external companies called providers where each person gets assigned a coach that can assist them in achieving an employment quicker.
