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. Text Curation for Clustering of Free-text Survey Responses

   Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

   Författare :Anton Gefvert; [2023]
   Nyckelord :Natural Language Processing; NLP; Sentence Representations; Sentence Representation Models; Survey; Surveys; Clustring;

   Sammanfattning : When issuing surveys, having the option for free-text answer fields is only feasible where the number of respondents is small, as the work to summarize the answers becomes unmanageable with a large number of responses. Using NLP techniques to cluster these answers and summarize them would allow a greater range of survey creators to incorporate free-text answers in their survey, without making their workload too large.

7. 5. Text Steganalysis based on Convolutional Neural Networks

   Kandidat-uppsats, Blekinge Tekniska Högskola

   Författare :Tejasvi Akula; Varshitha Pamisetty; [2022]
   Nyckelord :CNN; text steganalysis; Deep Learning; Decision Strategy;

   Sammanfattning : The CNN-based steganalysis model is able to capture some complex statistical dependencies and also learn feature representations. The proposed model uses a word embedding layer to map the words into dense vectors thus, achieving more accurate representations of the words. The proposed model extracts both, the syntax and semantic features. LÄS MER
