Research Focus

Prof. Stilo’s research spans several areas of AI and Machine Learning, with a primary focus on addressing real-world problems that require large-scale data processing:

  • Graph Counterfactual Explainability (GCE): Developing methods and frameworks (GRETEL, RSGG-CE) to explain Graph Neural Network decisions through counterfactual reasoning. Published at AAAI, ACM Computing Surveys, WSDM, ECML-PKDD, CIKM, and IJCAI.

  • Machine Unlearning: Research on selective data removal from trained models (ERASURE framework, Forget-Set Identification problem), addressing GDPR compliance and responsible AI. Published in Machine Learning (Springer) and at CIKM/IJCAI.

  • Algorithmic Fairness & Bias: Founding the BIAS workshop series at ECIR (2020–2023), developing debiasing techniques for classification (Debiaser, IPM), and studying gender gaps in academia and enterprise social networks (JSS, Social Networks).

  • Health Informatics & Computational Biology: Syndromic surveillance from social media (AIIM, PLoS One, BMC Infectious Diseases), drug repurposing via deep graph networks (IEEE TETC), disease-gene prediction (BIBM, SAC), and contributing to the CLAIRE COVID-19 Task Force.

  • Temporal & Social Mining: Efficient temporal mining of micro-blog texts for event discovery (DMKD), hashtag sense clustering (Computational Linguistics), topic detection in news providers (IDA), and buzzing story discovery in anomalous temporal graphs (WIJ).

  • Recommender Systems & User Profiling: Semantic recommendation for micro-blog users, automatic acquisition of user interest taxonomies (Web Semantics), multi-domain interest datasets (Wiki-MID at ISWC), topic recommenders for journalists (IRJ), and enterprise social network analytics (ICWSM, CSCWD).
