Community Search in Attributed Networks using Dominance Relationships and Random Walks
Nikolaos Georgiadis, Eleftherios Tiakas, Apostolos N. Papadopoulos
Community search in attributed networks poses a dual challenge: balancing structural connectivity -- the network's topological properties -- and attribute similarity -- the shared…
Multiple Similarity Drug-Target Interaction Prediction with Random Walks and Matrix Factorization
Bin Liu, Dimitrios Papadopoulos, Fragkiskos D. Malliaros +2
The discovery of drug-target interactions (DTIs) is a very promising area of research with great potential. The accurate identification of reliable interactions among drugs and pro…
NodeSig: Binary Node Embeddings via Random Walk Diffusion
Abdulkadir Çelikkanat, Fragkiskos D. Malliaros, Apostolos N. Papadopoulos
Graph Representation Learning (GRL) has become a key paradigm in network analysis, with a plethora of interdisciplinary applications. As the scale of networks increases, most of th…
Keywords lie far from the mean of all words in local vector space
Eirini Papagiannopoulou, Grigorios Tsoumakas, Apostolos N. Papadopoulos
Keyword extraction is an important document process that aims at finding a small set of terms that concisely describe a document's topics. The most popular state-of-the-art unsuper…
Distributed Computation of Top- Degrees in Hidden Bipartite Graphs
Panagiotis Kostoglou, Apostolos N. Papadopoulos, Yannis Manolopoulos
Hidden graphs are flexible abstractions that are composed of a set of known vertices (nodes), whereas the set of edges are not known in advance. To uncover the set of edges, multip…
Continuous Outlier Mining of Streaming Data in Flink
Theodoros Toliopoulos, Anastasios Gounaris, Kostas Tsichlas +2
In this work, we focus on distance-based outliers in a metric space, where the status of an entity as to whether it is an outlier is based on the number of other entities in its ne…
