Deep Graph Representation Learning and Optimization for Influence Maximization [PDF]
Influence maximization (IM) is formulated as selecting a set of initial users from a social network to maximize the expected number of influenced users. Researchers have made great progress in designing various traditional methods, and their theoretical ...

SimKGC: Simple Contrastive Knowledge Graph Completion with Pre-trained Language Models [PDF]
Knowledge graph completion (KGC) aims to reason over known facts and infer the missing links. Text-based methods such as KGBERT (Yao et al., 2019) learn entity representations from natural language descriptions, and have the potential for inductive KGC ...

On cospectrality of gain graphs
We define GG-cospectrality of two GG-gain graphs (Γ,ψ)\left(\Gamma ,\psi ) and (Γ′,ψ′)\left(\Gamma ^{\prime} ,\psi ^{\prime} ), proving that it is a switching isomorphism invariant.

MGTAB: A Multi-Relational Graph-Based Twitter Account Detection Benchmark [PDF]
The development of social media user stance detection and bot detection methods rely heavily on large-scale and high-quality benchmarks. However, in addition to low annotation quality, existing benchmarks generally have incomplete user relationships ...

Burnside Chromatic Polynomials of Group-Invariant Graphs
We introduce the Burnside chromatic polynomial of a graph that is invariant under a group action. This is a generalization of the Q-chromatic function Zaslavsky introduced for gain graphs.

Domain Entity Extraction Method Based on Graph Sorting and Maximal Information Gain [PDF]
Domain knowledge graphs play an important role in various industries, and the acquisition of the domain entity is an important basis for their construction.However, existing approaches frequently rely on human work such as data annotation and the ...

On the Fractionalization of the Shift Operator on Graphs
The theory of graph signal processing has been established with the purpose of generalizing tools from classical digital signal processing to the cases where the signal domain can be modeled by an arbitrary graph.
