  • Effective mining of software repositories 

    D'Ambros M; Robbes R (IEEE Computer Society, 2011)
    With the advent of open-source, the Internet, and the consequent widespread adoption of distributed development tools, such as software configuration management and issue tracking systems, a vast amount of valuable information ...
  • The effects of SA8000 certification on firm performances: An empirical analysis 

    Orzes G (C.R.I.G., 2015)
    The impact of CSR practices on firm performances has been attracting considerable attention since late 1980s. No agreement has however been reached so far about this (positive, negative, or neutral) impact. This paper ...
  • Efficient Axiom Pinpointing in EL using SAT Technology 

    Manthey N; Peñaloza R; Rudolph S (CEUR, 2016)
    We propose a novel approach to axiom pinpointing based on a reduction to the SAT task of minimal unsatisfiable subformula enumeration, allowing highly optimized algorithms and data structures developed for SAT solving in ...
  • Efficient evaluation of ad-hoc range aggregates 

    Ammendola, C; Böhlen, MH; Gamper, J (Springer, 2013)
    θ-MDA is a flexible and efficient operator for complex ad-hoc multi-dimensional aggregation queries. It separates the specification of aggregation groups for which aggregate values are computed (base table b) and the ...
  • Efficient Itinerary Planning with Category Constraints 

    Bolzoni P; Helmer S; Wellenzohn K; Gamper J; Andritsos P (Association for Computing Machinery, 2014)
    We propose a more realistic approach to trip planning for tourist applications by adding category information to points of interest (POIs). This makes it easier for tourists to formulate their preferences by stating ...
  • Efficient Ontology-Based Data Integration with Canonical IRIs 

    Xiao G; Hovland D; Bilidas D; Rezk M; Giese M; Calvanese D (Springer, 2018)
    In this paper, we study how to efficiently integrate multiple relational databases using an ontology-based approach. In ontology-based data integration (OBDI) an ontology provides a coherent view of multiple databases, and ...
  • Embedded lossy to lossless compression of hyperspectral images using JPEG 2000 

    Penna B; Tillo T; Magli E; Olmo G (IEEE, 2005)
    Hyperspectral image compression has recently attracted a remarkable interest for remote sensing applications. In this paper we propose a unified embedded lossy-to-lossless compression framework based on the JPEG 2000 ...
  • Emotion-aware recommender systems - A framework and a case study 

    Tkalčič M; Burnik U; Odić A; Košir A; Tasič J (Springer Verlag, 2013)
    Recent work has shown an increase of accuracy in recommender systems that use emotive labels. In this paper we propose a framework for emotion-aware recommender systems and present a survey of the results in such recommender ...
  • Emotions and personality in recommender systems: tutorial 

    Tkalcic M (ACM Press, 2018)
    This tutorial addresses the acquisition of emotions and personality for recommender systems. It is composed of two parts: (i) a short theoretical overview of emotions and personality and (ii) a hands-on part, in which we ...
  • EMPIRE 2013: Emotions and personality in personalized services 

    Tkalčič M; De Carolis B; De Gemmis M; Odić A; Košir A (CEUR-WS, 2013)
    The EMPIRE workshop attempts to provide some answers to the growing interest of the user modeling research community on the role of human factors, especially personality and emotions, on various aspects of user modeling. ...
  • EMPIRE 2015: Workshop on Emotions and Personality in Personalized Systems 

    Tkalcic M; Carolis BD; Gemmis M; Odic A; Kosir A (ACM, 2015)
    The EMPIRE workshop focuses on recommender systems (and other personalized systems) that take advantage of user-centric properties, such as emotions and personality. The workshop is organized as a focused mini-conference ...
  • Empirical analysis of impacts of instance-driven changes in ontologies 

    Abgaz, YM; Pahl, C (Springer-Verlag, 2010)
    Changes in the characterization of instances in digital content are one of the rationales to evolve ontologies that support a domain. These changes can have impacts on one or more of interrelated ontologies. Before ...
  • An empirical analysis on the discontinuous use of pair programming 

    Janes, A; Russo, B; Zuliani, P; Succi, G (Springer, 2003)
    Pair Programming has been shown to increase communication and teamwork skills and to provide better code. The aim of this work is to show the efficacy of Pair Programming in transferring knowledge and skills over an ...
  • An empirical investigation of perceived reliability of open source Java programs 

    Lavazza, L; Morasca, S; Taibi, D; Tosi, D (ACM, 2012)
    Background: Open Source Software (OSS) is used by a continuously growing number of people, both end-users and developers. The quality of OSS is thus an issue of increasing interest. Specifically, OSS stakeholders need to ...
  • An Empirical Investigation on the Motivations for the Adoption of Open Source Software 

    Taibi, D (IARIA, 2015)
    Open Source Software has evolved dramatically in the last twenty years and now many open source products are considered similar, or better, than proprietary solutions. The result is that the trustworthiness of some open ...
  • An empirical study of goto in C code from github repositories 

    Nagappan M; Robbes R; Kamei Y; Tanter É; Mcintosh S; Mockus A; Hassan A (Association for Computing Machinery, Inc, 2015)
    It is nearly 50 years since Dijkstra argued that goto obscures the flow of control in program execution and urged programmers to abandon the goto statement. While past research has shown that goto is still in use, little ...
  • An empirical study of the influence of static type systems on the usability of undocumented software 

    Mayer C; Hanenberg S; Robbes R; Tanter E; Stefik A (ACM, 2012)
    Although the study of static and dynamic type systems plays a major role in research, relatively little is known about the impact of type systems on software development. Perhaps one of the more common arguments for static ...
  • An empirical study of work fragmentation in software evolution tasks 

    Sanchez H; Robbes R; Gonzalez V (Institute of Electrical and Electronics Engineers Inc., 2015)
