  • Affective Issues in Adaptive Educational Environments 

    Leontidis, Makis; Halatsis, Constantin (IGI Global, 2009)
    Research in computer science recently began to take emotions into account because their influence in perception, reasoning, decision-making and learning is considered catalytic. In learning the appropriate sentimental ...

  • Combining Syntactic and Semantic Evidence for Improving Matching over Linked Data Sources 

    Christodoulou, Klitos; Fernandes, Alvaro A.A.; Paton, Norman W. (Springer Link, 2015-11)
    In the context of Linked Data (LD) sources, the ability to traverse links and retrieve further information can be exploited to harvest semantic annotations. Such annotations can, in turn, underpin the inference of semantic ...

  • A Comparative Study of Four Ontology Visualization Techniques in Protégé: Experiment Setup and Preliminary Results 

    Katifori, Akrivi; Torou, Elena; Halatsis, Constantin; Lepouras, Georgios; Vassilakis, Costas (IEEE Xplore, 2006)
    The continuing need for more effective information retrieval has lead to the creation of the notions of the semantic Web and personalized information management, areas of study that very often employ ontologies to represent ...

  • Constructing An Affective Path To Support Learners In A Distance Learning Environment 

    Leontidis, Makis; Halatsis, Constantin (2009-07)
    This paper presents an ontology-based method for the selection of the suitable sequence of affective tactics in the context of MENTOR. MENTOR is a Web-based Adaptive Educational Environment where the learner’s needs and ...

  • Context and Adaptivity-Driven Visualization Method Selection 

    Golemati, Maria; Vassilakis, Costas; Katifori, Akrivi; Lepouras, George; Halatsis, Constantin (Premier Reference Source, 2008-09)
    Novel and intelligent visualization methods are being developed in order to accommodate user searching and browsing tasks, including new and advanced functionalities. Besides, research in the field of user modeling is ...

  • e-Learning Issues under an Affective Perspective 

    Leontidis, Makis; Halatsis, Constantin; Grigoriadou, Maria (Springer Berlin Heidelberg, 2008)
    The aim of this paper is to present an Affective Educational Module for distance learning which is called MENTOR. MENTOR constitutes of three main components, the Emotional Component, the Teacher Component and the Visualization ...

  • Efficient modular design of TSC checkers for m-out-of-2m codes 

    Paschalis, A. M.; Nikolos, D.; Halatsis, Constantin (Springer Berlin Heidelberg, 1986)
    A new design method of TSC m-out-of-2m code checkers is presented. The design is composed basically of two full-adder/half-adder trees, each summing-up the one's of m input lines, and a k-variable 2-pair two-rail code tree ...

  • Efficient Test Generation for Register Transfer Level Descriptions 

    Stamelos, I.; Halatsis, Constantin (1987)
    Test generation based on high level circuit descriptions, has been proposed in the recent years, for LSI and VLSI products. However, not all aspects of the problem have been thoroughly examined. This paper describes an ...

  • eg-GRIDS: Context-Free Grammatical Inference from Positive Examples Using Genetic Search 

    Petasis, Georgios; Paliouras, Georgios; Spyropoulos, Constantine D.; Halatsis, Constantin (Springer Berlin Heidelberg, 2004)
    In this paper we present eg-GRIDS, an algorithm for inducing context-free grammars that is able to learn from positive sample sentences. The presented algorithm, similar to its GRIDS predecessors, uses simplicity as a ...

  • Employing Cellular Automata for Shaping Accurate Morphology Maps Using Scattered Data from Robotics’ Missions 

    Kapoutsis, Athanasios Ch.; Chatzichristofis, Savvas A.; Sirakoulis, Georgios Ch.; Doitsidis, Lefteris; Kosmatopoulos, Elias B. (Springer, 2015)
    Accurate maps are essential in the case of robot teams, so that they can operate autonomously and accomplish their tasks efficiently. In this work we present an approach which allows the generation of detailed maps, suitable ...

  • Extensions to a parallel prolog system to support real-time applications 

    Mourlas, Constantin; Halatsis, Constantin (Springer Berlin Heidelberg, 1992)
    In this article, we first discuss the Real-Time (RT) programming issues and what language support should be provided for building RT applications. Then we propose a set of RT extensions for a parallel Prolog system and we ...
