Elisa Quintarelli - Böcker

This book constitutes the proceedings of the 24th International Conference, ICWE 2024, held in Tampere, Finland, during June 17-20, 2024. The 16 full papers and 8 short papers included in this volume were carefully reviewed and selected from 66 submissions.This volume includes all the accepted papers across various conference tracks.The ICWE 2024 theme, “Ethical and Human-Centric Web Engineering: Balancing Innovation and Responsibility,” invited discussions on creating Web technologies that are not only innovative but also ethical, transparent, privacy-focused, trustworthy, and inclusive, putting human needs and well-being at the core.

This book constitutes short papers, Doctoral Consortium and workshop papers which were presented at the 29th European Conference on New Trends in Databases and Information Systems, ADBIS 2025, which took place in Tampere, Finland, during September 23-26, 2025. This CCIS proceedings book contains 14 short papers and 3 demo papers from the main ADBIS 2025 conference. In addition, 24 out of 48 papers submitted to the workshops are included in this book. The papers have been organized in topical sections as follows: Query Optimization; Spatio-Temporal & Graph Data;  Data Sharing & Synthesis; Entity Resolution & Integration; Doctoral Consortium School Invited Talks; MADEISD 2025: 7th Workshop on Modern Approaches in Data Engineering and Information System Design; DOING 2025: 6th Workshop on Intelligent Data - From Data to Knowledge;K-GALS 2025: 4th Workshop on Knowledge Graphs Analysis on a Large Scale; CAIMA 2025: 1st Workshop on Cooperative AI Models and Applications; ERGA 2025: 1st Workshop on Entity Resolution and Graph Alignment; FEHDA 2025: 1st Workshop on Fairness Exploration in Heterogeneous Data and Algorithms; and IT4TOCI 2025: 1st Workshop on Information Technology for Tourism and Culture Industries.

This thesis deals with the problems of characterizing the semantics of and assuringe?cient executionfor databasequery languages,wherethedatabase contains semistructured and time-varying information. This area of techn- ogy is of much interest and signi?cance for databases and knowledge bases; it also presents many challenging research problems deserving an in-depth investigation.Thus, the topic of Elisa Quintarelli's dissertation is well chosen and totally appropriate to the current research trends. In her thesis, Elisa addresses a number of related problems. However, her work and contributions concentrate on two main problems. The ?rst is the de?nition of an e?ective graph-based approach to the formalization of query languages for semistructured and temporal information. In her approach, query execution is viewed as the process of matching the query graph with the database instance graph; therefore, query execution reduces to sear- ing the database for subgraphs that are similar to the given query graph. The search for such matches can be supported through the computational process of bisimulation. This approach is used to de?ne the semantics of s- eral languages, including graphical languages, such as G-Log and GraphLog, semistructuredinformationlanguages,suchasLorel,andtemporallanguages, such as TSS-QL.Both graph-based approaches and bisimulation had been used by previous authors for de?ning query languages and their semantics; however, this work goes well beyond previous approaches by integrating and re?ning these techniques into a ?exible and powerful paradigm that Elisa demonstrates to be e?ective on a spectrum of languages and a suite of alt- native semantics.
