Transformations for Evolving Property Graph Schemas
Gauvain Devillez, Stefania Dumbrava, Angela Bonifati
Property graph databases are widely used to represent complex and evolving data, yet systematic support for property graph schema evolution remains limited. In practice, schema tra…
Are Large Language Models Suitable for Graph Computation? Progress and Prospects
Yuting Zhang, Yi Han, Kai Wang +3
Large language models (LLMs) have been increasingly explored for graph computation, where tasks require reasoning over structured relationships and algorithmic operations. Yet, it…
Repairing Property Graphs under PG-Constraints
Christopher Spinrath, Angela Bonifati, Rachid Echahed
Recent standardization efforts for graph databases lead to standard query languages like GQL and SQL/PGQ, and constraint languages like Property Graph Constraints (PG-Constraints).…
What If: Causal Analysis with Graph Databases
Amedeo Pachera, Mattia Palmiotto, Angela Bonifati +1
Graphs are expressive abstractions representing more effectively relationships in data and enabling data science tasks. They are also a widely adopted paradigm in causal inference…
Low-Latency Sliding Window Connectivity
Chao Zhang, Angela Bonifati, Tamer Özsu
Connectivity queries, which check whether vertices belong to the same connected component, are fundamental in graph computations. Sliding window connectivity processes these querie…
Path-based Algebraic Foundations of Graph Query Languages
Renzo Angles, Angela Bonifati, Roberto García +1
Graph databases are gaining momentum thanks to the flexibility and expressiveness of their data models and query languages. A standardization activity driven by the ISO/IEC standar…
Transforming Property Graphs
Angela Bonifati, Filip Murlak, Yann Ramusat
In this paper, we study a declarative framework for specifying transformations of property graphs. In order to express such transformations, we leverage queries formulated in the G…
Incremental Sliding Window Connectivity over Streaming Graphs
Chao Zhang, Angela Bonifati, M. Tamer Özsu
We study index-based processing for connectivity queries within sliding windows on streaming graphs. These queries, which determine whether two vertices belong to the same connecte…
