  • Gamified children universities: an exploratory study 

    Dodero, G; Gennari, R; Melonio, A; Montali, M; Razniewski, S; Torello, S; Wang, X; Zini, F; Del Fatto, V (ACM, 2014)
    Children universities see universities hosting activities for exposing children to research findings. However, universities are not per-se designed for children. This paper advances the idea of gamifying university contexts ...
  • Gamified Technology Probes for Scaffolding Computational Thinking 

    Gennari, R; del Fatto, V; Gashi, E; Sanin, J; Ventura, A (Springer, 2016)
    This paper advances the idea of gamified probes for scaffolding children’s computational thinking, and specifically algorithmic thinking. The paper presents the making of such a probe for a sorting algorithm. The making ...
  • Gamify your Field Studies for Learning about Your Learners 

    Mascio, T; Gennari, R; Melonio, A; Vittorini, P (Springer, 2013)
    TERENCE is an FP7 ICT European project that developed a technology enhanced learning system for supporting its learners, who are primary school children, and their educators. In the course of the project, we run field ...
  • A General Framework for Shape Similarity 

    Borgo, S; Kutz, O (CEUR-WS.org, 2011)
    We propose a formal framework to clarify the import of and the relationship among different notions of similarity. The framework, borrowing from the general E-connections approach, allows to use multiple similarity notions ...
  • Generating Preview Instances for the Face Validation of Entity-Relationship Schemata: The Acyclic Case 

    Amalfi M; Artale A; Calì A; Provetti A (Springer, 2011)
    We describe a mapping of Extended Entity-Relationship schemata to Answer Set Programming that allows us to generate informative example instances of the relational database that is implied by the conceptual schema. Such ...
  • The generation of e-learning exercise problems from subject ontologies 

    Holohan E; Melia M; McMullen D; Pahl C (Institute of Electrical and Electronics Engineers, 2006)
    The teaching/ learning of cognitive skills, such as problem-solving, is an important goal in most forms of education. In well-structured subject areas certain exercise problem types may be precisely described by means of ...
  • A Generic Approach for Large-Scale Ontological Reasoning in the Presence of Access Restrictions to the Ontology's Axioms 

    Baader, F; Knechtel, M; Penaloza, R (Springer, 2009)
    The framework developed in this paper can deal with scenarios where selected sub-ontologies of a large ontology are offered as views to users, based on criteria like the user’s access right, the trust level required by the ...
  • Genre-based Analysis of Social Media Data on Music Listening Behavior: Are Fans of Classical Music Really Averse to Social Media? 

    Schedl M; Tkalcic M (ACM, 2014)
    It is frequently presumed that lovers of Classical music are not present in social media. In this paper, we investigate whether this statement can be empirically verified. To this end, we compare two social media platforms ...
  • Geo-activity recommendations by using improved feature combination 

    Sattari M; Manguoglu M; Toroslu IH; Symeonidis P; Senkul P; Manolopoulos Y (ACM, 2012)
    In this paper, we propose a new model to integrate additional data, which is obtained from geospatial resources other than original data set in order to improve Location/Activity recommendations. The data set that is used ...
  • Geo-social recommendations based on incremental tensor reduction and local path traversal 

    Symeonidis P; Papadimitriou A; Manolopoulos Y; Senkul P; Toroslu I (ACM, 2011)
    Social networks have evolved with the combination of geographical data, into Geo-social networks (GSNs). GSNs give users the opportunity, not only to communicate with each other, but also to share images, videos, locations, ...
  • Global Motion Information Based Depth Map Sequence Coding 

    Cheng F; Xiao JM; Tillo T; Zhao Y (SPRINGER, 2015)
    Depth map is currently exploited in 3D video coding and computer vision systems. In this paper, a novel global motion information assisted depth map sequence coding method is proposed. The global motion information of depth ...
  • Goal-based composition of stateful services for smart homes 

    De Giacomo G; Di Ciccio C; Felli P; Hu Y; Mecella M (Springer, 2012)
    The emerging trend in process management and in service oriented applications is to enable the composition of new distributed processes on the basis of user requests, through (parts of) available (and often embedded in the ...
  • Gödel Description Logics with General Models 

    Borgwardt S; Distel F; Peñaloza R (CEUR, 2014)
    In the last few years, the complexity of reasoning in fuzzy description logics has been studied in depth. Surprisingly, despite being arguably the simplest form of fuzzy semantics, not much is known about the complexity ...
  • Gödel FL0 with Greatest Fixed-Point Semantics 

    Borgwardt, S; Peñaloza, R; Leyva Galano, JA (CEUR, 2014)
    We study the fuzzy extension of FL0 with semantics based on the Gödel t-norm. We show that gfp-subsumption w.r.t. a nite set of primitive denitions can be characterized by a relation on weighted automata, and use this ...
  • Gödel Negation Makes Unwitnessed Consistency Crisp 

    Borgwardt S; Distel F; Penaloza R (CEUR, 2012)
    Ontology consistency has been shown to be undecidable for a wide variety of fairly inexpressive fuzzy Description Logics (DLs). In particular, for any t-norm "starting with" the Lukasiewicz t-norm, consistency of crisp ...
  • Graph-based discovery of ontology change patterns 

    Javed M; Abgaz YM; Pahl C (CEUR, 2011)
    Ontologies can support a variety of purposes, ranging from capturing conceptual knowledge to the organisation of digital content and information. However, information systems are always subject to change and ontology change ...
  • Graph-based implicit knowledge discovery from architecture change logs 

    Aakash A; Jamshidi P; Arshad M; Pahl C (ACM, 2012)
    Service architectures continuously evolve as a consequence of frequent business and technical change cycles. Architecture change log data represents a source of evolution-centric information in terms of intent, scope and ...
  • Graph-based pattern identification from architecture change logs 

    Ahmad A; Jamshidi P; Pahl C (Springer, 2012)
    Service-based architectures have become commonplace, creating the need to address their systematic maintenance and evolution. We investigate architecture change representation, primarily focusing on the identification of ...
  • A greedy approach towards parsimonious temporal aggregation 

    Gordevicius, J; Gamper, J; Böhlen, M (IEEE, 2008)
    Temporal aggregation is a crucial operator in temporal databases and has been studied in various flavors. In instant temporal aggregation (ITA) the aggregate value at time instant t is computed from the tuples that hold ...
