Grafixer: Enabling User-Centric Repairs for Property Graphs
Published in SIGMOD/PODS'25: International Conference on Management of Data, 2025
We introduce Grafixer, an innovative interactive tool that enables human-in-the-loop repair of property graphs. By leveraging user expertise, Grafixer allows collaborative identification and correction of data inconsistencies while ensuring an efficient repair process. Users can upload property graph datasets and define constraints using Cypher, a widely adopted query language. The system efficiently manages overlapping data violations, ensuring that multiple users can work simultaneously on independent repairs without conflicts. Additionally, Grafixer provides an interactive dashboard that allows administrators to monitor real-time statistics, track progress, and oversee the repair process. In our demo, we showcase the complete repair workflow from both the administrator and users perspectives. Administrators can configure the repair process, monitor ongoing corrections, and assess the overall status of the graph. Meanwhile, users engage in the repair process by reviewing violations, proposing corrections, and contributing to improving data quality through an intuitive and guided interface.

User-Centric Property Graph Repairs
Published in SIGMOD/PODS'25: International Conference on Management of Data, 2025
Property graphs serve as unifying abstractions for encoding, inspecting, and updating interconnected data with greater expressive power. They are increasingly popular across various application domains involving real users. However, graph data often contains inconsistencies that need proper transformations to address underlying constraint violations and often require specific domain knowledge. In this paper, we propose an interactive and user-centric approach to repair property graphs under denial constraints. Our approach includes a novel theoretical framework comprising a query-based inconsistency detection mechanism, a dependency graph for tracking violations, and an assignment algorithm facilitating multi-user property graph repairs by leveraging independent sets. We evaluate our approach through several experiments on real-world and synthetic datasets, considering different levels of user expertise and comparing against various baselines. Even with multiple non-oracle users, our approach outperforms existing interactive and non-interactive baselines by 30% on average in terms of repair quality. Additionally, we conduct a user study to assess real user performance in property graph repairs
