Temporal Evolution of Scholarly Communication
The general topic of the dissertation is citation network dynamics. I employ two perspectives on the evolution of citation networks in order to extend our understanding of the context of scientific progress. The first two sections develop a general mechanism to predict how papers gain attention and …

Mapping the open-source ecosystem
… advances. This dissertation uses tools from citation networks and applies them to dependencies in open-source networks taken from the dataset provided by Libraries.io in order to understand the structure and prevailing patterns inherent to open source ecosystems.

A web API service for calculating credit attributable to authors
… by research on the UniCoin platform by means of citation network analysis and the calculation of centrality measures. In particular, I present a web service that is able to generate citation networks for a given piece of research and from them to efficiently calculate measures of the contribution …

Storage and processing systems for power-law graphs
Large graphs abound around us - online social networks, Web graphs, the Internet, citation networks, protein interaction networks, telephone call graphs, peer-to-peer overlay networks, electric power grid networks, etc. Many real- life graphs are power-law graphs. A fundamental challenge in today’s …

Graph structures, random walks, and all that : learning graphs with jumping knowledge networks
… of drugs, community detection in social networks, and modeling interactions in physical systems. Recent deep learning approaches for graph representation learning, namely Graph Neural Networks (GNNs), follow a neighborhood aggregation procedure, where the representation vector of a node …

Deep Representation Learning on Labeled Graphs
… train generative models, generative adversarial networks (GANs) have achieved considerable success in image generation, and this framework has also recently been applied to data with graph structures. We identify the drawbacks of existing deep frameworks for generating graphs, and we propose …

Social impact retrieval: measuring author influence on information retrieval
… larger-scale experiment based on the author and citation networks of a ten year period of the ACM SIGIR conference on information retrieval between 1997-2007. We use the citation context of SIGIR publications as a proxy for annotations, constructing large social networks between authors. Against …

Prediction and modelling of complex social networks and their evolution.
This thesis focuses on complex social networks in the context of computational approaches for their prediction and modelling. The increasing popularity and advancement of social net- works paired with the availability of social network data enable empirical analysis, inference, prediction and …

Algorithms For Discovering Communities In Complex Networks
It has been observed that real-world random networks like the WWW, Internet, social networks, citation networks, etc., organize themselves into closely-knit groups that are locally dense and globally sparse. These closely-knit groups are termed communities. Nodes within a community are similar in …

The Evolution of Topological Concepts in Online Social Networks
Online Social Networks (OSNs) enable individual users to connect with others, contribute to discussions and share their content. The data created in these platforms contain relationships between users and user generated content. User relationships can be represented by a social network, while user …

How to attribute credit if you must
… to new pieces of academic research, using citation network analysis and centrality measures. Katz centrality, in-degree centrality, and PageRank are three potentially useful centrality measures, with varying results: these are compared using case studies based on three papers co-authored by …

Systems Biology Approach to Identifying Host Interactive Pathways Modulating the Severity of Streptococcal Sepsis
… Based on linkage analyses, gene ontology, co-citation networks, and variations in gene expression, we identified interleukin 1 (IL1) and prostaglandin E (PGE) pathways as prime candidates associated with modulating the severity of GAS sepsis.</p> <p>To further investigate mechanisms underlying …

Analyzing The Community Structure Of Web-like Networks: Models And Algorithms
… investigates the community structure of web-like networks (i.e., large, random, real-life networks such as the World Wide Web and the Internet). Recently, it has been shown that many such networks have a locally dense and globally sparse structure with certain small, dense subgraphs occurring much …
