    • A New Framework for the Citation Indexing Paradigm 

      Δέρβος, Δημήτρης; Σαμαράς, Νικόλαος; Ευαγγελίδης, Γεώργιος; Folias, Theodore; Dervos, Dimitris; Samaras, Nikolaos; Evangelidis, Georgios (2006)
      A new citation indexing paradigm is proposed: the cascading citation indexing framework (c2IF, for short). It improves the way research publications are assessed for their impact in promoting science and technology. Given ...

    • Dimensionality Curse, Concentration Phenomenon and the KDB-tree 

      Ευαγγελίδης, Γεώργιος; Κουιρουκίδης, Νικόλαος; Evangelidis, Georgios; Kouiroukidis, Nikolaos (2011)
      The problem of indexing large volumes of high dimensional data is an important and popular issue in the area of database management. There are many indexing methods that behave well in low dimensional spaces, but, in high ...

    • Directory of Hellenic Academic and Research Entities (D.H.A.R.E.) 

      Δέρβος, Δημήτρης; Ευαγγελίδης, Γεώργιος; Ντονάς, Κωνσταντίνος; Νίτσος, Ηλίας; Πετρίδης, Θάνος; Dervos, Dimitris; Evangelidis, Georgios; Nitsos, Ilias; Ntonas, Konstantinos; Petridis, Thanos (2015)
      The Directory of Hellenic Academic and Research Entities (DHARE for short) comprises an act undertaken under the Hellenic Libraries Link (HEAL-Link) project titled "Advanced Services for Open Access Digital Libraries" ...

    • An Extensive Experimental Study on the Cluster-based Reference Set Reduction for Speeding-up the k-NN Classifier 

      Δέρβος, Δημήτρης; Ευαγγελίδης, Γεώργιος; Ουγιάρογλου, Στέφανος; Dervos, Dimitris; Evangelidis, Georgios; Ougiaroglou, Stefanos (2011)
      The k-Nearest Neighbor (k-NN) classification algorithm is one of the most widely-used lazy classifiers because of its simplicity and ease of implementation. It is considered to be an effective classifier and has many ...

    • g-binary: a new non-parameterized code for improved inverted file compression 

      Νίτσος, Ηλίας; Δέρβος, Δημήτρης; Ευαγγελίδης, Γεώργιος; Dervos, Dimitris; Evangelidis, Georgios; Nitsos, Ilias (2003)
      The inverted file is a popular and efficient method for indexing text databases and is being used widely in information retrieval applications. As a result, the research literature is rich in models (global and local) that ...

    • Improving Query Efficiency in High Dimensional Point Indexes 

      Ευαγγελίδης, Γεώργιος; Ούτσιος, Ευάγελος; Evangelidis, Georgios; Outsios, Evangelos (2011)
      In this paper, we focus on the leaf level nodes of tree-like k-dimensional indexes that store the data entries, since those nodes represent the majority of the nodes in the index. We propose a generic node splitting approach ...
