Ontology-Based Data Access for Extracting Event Logs from Legacy Data: The onprom Tool and Methodology [chapter]

Diego Calvanese, Tahir Emre Kalayci, Marco Montali, Stefano Tinella
2017 Lecture Notes in Business Information Processing  
Our approach is based on describing logs by means of suitable annotations of a conceptual model of the available data, and builds on the ontology-based data access (OBDA) paradigm for the actual log extraction  ...  In this work, we exploit a framework and associated methodology for the extraction of XES event logs from relational data sources that we have recently introduced.  ...  We thank Ario Santoso for the development of the log extraction plug-in of onprom, and Wil van der Aalst for the interesting discussions and insights on the problem of extracting event logs from legacy  ...

Virtual Knowledge Graphs: An Overview of Systems and Use Cases

Guohui Xiao, Linfang Ding, Benjamin Cogrel, Diego Calvanese
2019 Data Intelligence  
In this paper, we present the virtual knowledge graph (VKG) paradigm for data integration and access, also known in the literature as Ontology-based Data Access.  ...  From a technological point of view, the main vendors of data integration tools [1] are integrating data using the standard relational † Corresponding author: Linfang Ding (  ...  To cope with this kind of problem, the approach proposed in [66] exploits a VKG based framework and associated methodology for the extraction of XES event logs from relational data sources.  ...
