A query engine prototype for personalization of multi-version XML documents with respect to multi-version reference ontologies

This software product implements a prototype of the query engine representing the core of the personalization framework for multi-version XML repositories described in the paper "Multi-version Ontology-based Personalization of Clinical Guidelines for Patient-centric Healthcare" (doi:10.4018/IJSWIS.2017010106, IRIS ID: 11585/579894) and used for performance evaluation of the proposed personalization approach, designed to deal with with multi-version reference ontologies. The query engine, implementing optimized combinations of various solutions based on a holistic technology for effecting multi-version slicing of XML documents according to both temporal and semantic user-defined constraints, has been developed using Java JDK 1.6 and ad hoc data structures. With respect to the version used for the experimental part of the work "Multi-version Ontology-based Personalization of Clinical Guidelines for Patient-centric Healthcare", in the current version of the prototype, management of accessory data structures for the application of semantics aspects has been improved. The prototype is running on an Intel Core i7 2.3Ghz OS X workstation, equipped with 8 GB RAM and a 256 GB SSD hard drive, located at the University of Modena and Reggio Emilia.
