    • 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)
      Information workers and software developers are exposed to work fragmentation, an interleaving of activities and interruptions during their normal work day. Small-scale observational studies have shown that this can be ...
    • Enabling Fine-grained RDF Data Completeness Assessment 

      Darari, F; Razniewski, S; Prasojo, RE; Nutt, W (Springer, 2016)
      Nowadays, more and more RDF data is becoming available on the Semantic Web. While the Semantic Web is generally incomplete by nature, on certain topics, it already contains complete information and thus, queries may return ...
    • Enabling program comprehension through a visual object-focused development environment 

      Olivero F; Lanza M; D'Ambros M; Robbes R (IEEE Computer Society, 2011)
      Integrated development environments (IDEs) include many tools that provide the means to construct programs. Coincidentally, the very same IDEs are a primary vehicle for program comprehension. We claim that IDEs may be an ...
    • Encoding preference queries to an uncertain database in possibilistic answer set programming 

      Confalonieri R; Prade H (Springer Verlag, 2012)
      The representation of preference queries to an uncertain data-base requires a framework capable of dealing with preferences and uncertainty in a separate way. Possibilistic logic has shown to be a suitable setting to support ...
    • Energy-Aware Performance Evaluation of Android Custom Kernels 

      Corral L; Georgiev A; Janes A; Kofler S (IEEE, 2015)
