  • Efficiently Maintaining Structural Associations of Semistructured Data  
  • by Dimitrios Katsaros — 2003 — Lecture Notes on Computer Science (LNCS
  • …Semistructured data arise frequently in the Web or in data integration systems. Semistructured objects describing the same type of information have similar but not identical structure. Finding the common schema of a collection of semistructured objects is a very important task and due to the huge vo…

  • Broadcast program generation for Webcasting  
  • by Dimitrios Katsaros, Yannis Manolopoulos — 2004
  • …The advances in computer and communication technologies have made possible an ubiquitous computing environment were clients equipped with portable devices can send and receive data anytime and from anyplace. In such an asymmetric communication environment, data push has emerged as a very e#ective an…

  • A Suffix Tree Based Prediction Scheme for Pervasive Computing Environments  
  • by Dimitrios Katsaros, Yannis Manolopoulos — 2005 — In Lecture notes in computer science (LNCS
  • …Discrete sequence modeling and prediction is a fundamental goal and a challenge for location-aware computing. Mobile client's data request forecasting and location tracking in wireless cellular networks are characteristic application areas of sequence prediction in pervasive computing, where lea…

  • Caching in Web memory hierarchies  
  • by Dimitrios Katsaros, Yannis Manolopoulos — 2004 — Proceedings of the ACM Symposium on Applied Computing
  • …Web cache replacement algorithms have received a lot of attention during the past years. Though none of the proposed algorithms deals e#ciently with all the particularities of the Web environment, namely, relatively weak temporal locality (due to filtering e#ects of caching hierarchies), heterogenei…

  • Exploiting Web Log Mining for Web Cache Enhancement  
  • by Alexandros Nanopoulos, Dimitrios Katsaros, Yannis Manolopoulos — 2002 — in WEBKDD ’01: Revised Papers from the Third International Workshop on Mining Web Log Data Across All Customers Touch Points
  • …Improving the performance of the Web is a crucial requirement, since its popularity resulted in a large increase in the user perceived latency. In this paper, we describe a Web caching scheme that capitalizes on prefetching. Prefetching refers to the mechanism of deducing forthcoming page access…

  • A Data Mining Algorithm for Generalized Web Prefetching  
  • by Alexandros Nanopoulos, Dimitrios Katsaros, Yannis Manolopoulos — 2003 — IEEE TRANSACTIONS ON KNOWLEDGE AND DATA ENGINEERING
  • …Predictive Web prefetching refers to the mechanism of deducing the forthcoming page accesses of a client based on its past accesses. In this paper, we present a new context for the interpretation of Web prefetching algorithms as Markov predictors. We identify the factors that affect the performanc…

  • ABSTRACT Cooperative Caching in Wireless Multimedia Sensor Networks ∗  
  • by Nikos Dimokas, Dimitrios Katsaros, Informatics Department
  • …The recent advances in miniaturization and the creation of low-power circuits, combined with small-sized batteries have made the development of wireless sensor networks a working reality. Lately, the production of cheap CMOS cameras and microphones gave birth to what is called Wireless Multimedia Se…

  • Social Network Analysis and its Applications in Wireless Sensor and Vehicular Networks  
  • by Alexis Papadimitriou, Dimitrios Katsaros, Yannis Manolopoulos
  • …Abstract. Ever since the introduction of wireless sensor networks in the research and development agenda, the corresponding community has been eager to harness the endless possibilities that this new technology has to offer. These micro sensor nodes, whose capabilities have skyrocketed over the last…
