Current Research Projects
A platform for dynamic exploration of the cooperative health research in South Tyrol study data via multi-level network medicine (DyHealthNet)
Aims at developing a network-based software platform for dynamic and explorative analysis of the cohort data from the Cooperative Health Research in South Tyrol (CHRIS) study, the largest population cohort in Italy. The project is a collaboration between unibz, EURAC Research, the Friedrich-Alexander-University Erlangen-Nürnberg, and TU Munich. [more]Data Driven Anomaly Detection for Sustainable Water and Energy Smart Grids Management (DIADEM)
Aims at developing a framework for the sustainable use of energy and drinking water by supporting smart distribution systems with data driven managing tools. The project is a collaboration between the Faculty of Science and Technology and the Faculty of Computer Science at unibz. [more]Finished Research Projects
Predictive Maintenance for Industrial Equipment (PREMISE)
Aims at developing a framework for predictive maintenance for industrial assets. The project is a collaboration between unibz and the two industrial partners Durst and TechnoAlpin. [more]Enabling Industrial-Strength, Open-Source Temporal Query Processing (ISTeP)
Aims aims at boosting the efficiency and scalability of query processing in the temporal alignment framework. The tasks are to develop new temporal primitives, improving cost estimates, and providing equivalence rules. [more]Temporal Relational Database Management Systems
Aims at extending RDBMs with support for querying interval-timestamped data under sequenced semantics. The basic idea is to reduce the temporal operators to the non-temporal counterparts. Our solution is implemented in the kernel of PostgreSQL. [more]An Intelligent Analysis Platform for Stock Market Data (ISMarD)
Aims at building a data management and analysis framework for stock market time series data that supports various forms of historical analyses. [more]Temporal Data Analytics
Aims at developing solutions for analyzing temporal data. Specific addressed research problems include the development of algorithms for efficient computation of aggregation operators, the computation of approximation of aggregation result sets, support for visual data analysis. [more]GEDLIB
GEDLIB is an easily extensible C++ library for (suboptimally) computing the graph edit distance (GED) between two labeled graphs. GED is defined as the minimum cost of a sequence of elementary edit operations that transforms one graph into another. There are six elementary edit operations: changing the label of an existing node, inserting an isolated node, deleting an isolated node, changing the label of an existing edge, inserting an an edge between two existing nodes, and deleting an edge. GEDLIB implements several state of the art methods for computing GED and comes with predefined edit costs for some benchmark datasets. Further methods and edit costs can easily be implemented by the user. [more]Paper accepted at LPAR 2024
