Research Projects
MODAP - Mobility, Data Mining, and Privacy
(FET OPEN, 2009-2012)
Abstract: With GPS enabled devices and other positioning systems, mobility behavior of individuals is captured for online or historical data analysis. For example, car insurance companies have started to issue policies with respect to the driving behavior which is captured through a GPS device installed under a special agreement. [more]
GeoPKDD - Geographic Privacy-aware Knowledge Discovery and Delivery
(FP6/IST project, 2005-09)
Abstract: The general goal of the GeoPKDD project is to develop theory, techniques and systems for knowledge discovery and delivery, based on new automated privacy-preserving methods for extracting user-consumable forms of knowledge from large amounts of raw data referenced in space and in time.

Diachoron - Management of Spatio-temporal and Semantic Data for the Documentation of Historical Information
(ΠΕΠ ΑΤΤΙΚΗΣ)
Abstract: Diachoron aims at the development of a model to represent the spatiotemporal developments of various types of historical information. More specifically, it focuses at the modeling of the borders (e.g. phycical, administrative and/or imaginable -- coastlines, abuttals, proliferation of various phenomenon -- and of their respective mutation during certain time intervals. The whole process is assisted by integrating various types of metadata related to the documentation of the spatio-temporal alterations. [more]
MetaOn - Ontology Driven Metadata Construction and Management for Intelligent Search in Text and Image Collections
(ΓΓΕΤ)
Abstract: The core objective of MetaOn is to construct and integrate semantically rich metadata collections extracted from documents images and linguistic resources, to facilitate intelligent search and analysis. The MetaOn framework involves, ontology-based information extraction and data mining, semi-automatic construction of domain specific ontologies, content-based image indexing and retrieval, and metadata management.

Pattern Representation, Storage and Retrieval using a PBMS architecture
(PENED 2003 Programme, 2005-08)
Abstract: An XML approach for handling patterns in a Pattern-Base Management System (PBMS). Export patterns from Data Mining tools and import them into a PBMS. [more]
Spatio-temporal Data and Knowledge Management in Expert Virtual Environments
(EPEAEK II / Pythagoras Programme, 2004-06)
Abstract: Investigation of novel techniques for the representation and management of spatio-temporal data and knowledge with applications in intelligent virtual environments, i.e. realistic synthetic worlds "inhabited" by graphical intelligent and interactive agents. [more]
Knowledge Discovery and Pattern Management – the PBMS approach
(EPEAEK II / Heracletos Programme, 2003-05)
Abstract: Development of a prototype Pattern-Base Management System (PBMS) for handling patterns extracted from large databases using data mining techniques. [more]
Moving Object Data Management on the World Wide Web
(EPEAEK II / Archimedes Programme, 2003-06)
Abstract: Development of technologies and a prototype, Web-based data management system for moving object applications, including Location-based Services (LBS). [more]
