  • Automatic Query Performance Assessment during the Retrieval of Software Artifacts 

    Haiduc S; Bavota G; Oliveto R; De Lucia A; Marcus A (ACM, 2012)
    Text-based search and retrieval is used by developers in the context of many SE tasks, such as, concept location, traceability link retrieval, reuse, impact analysis, etc. Solutions for software text search range from ...
  • Back to the Future: An Interaction-oriented Framework for Social Computing 

    Baldoni M; Baroglio C; Marengo E; Patti V; Ricci A (IEEE, 2011)
    We propose an interaction-oriented framework and the related support infrastructure, that reifies commitment-based interaction protocols into programmable environments and artifacts. The use of commitments gives a normative ...
  • Rewrite and Conquer: Dealing with Integrity Constraints in Data Integration 

    Calì A; Calvanese D; De Giacomo G; Lenzerini M (Springer, 2013)
    The work "Data Integration under Integrity Constraints'', published at the CAiSE~2002 Conference, proposes a rewriting technique for answering queries in data integration systems, when the global schema contains the classical ...
  • Desk-Mates (Stable Matching) with Privacy of Preferences, and a New Distributed CSP Framework 

    Silaghi M; Abhyankar A; Zanker M; Barták R (AAAI Press, 2005)
    The desk-mates matcher application places students in pairs of two for working in projects (similar to the well known problems of stable matchings or stable roommates). Each of the students has a (hopefully stable) secret ...
  • Sequenced spatiotemporal aggregation for coarse query granularities 

    Timko I; Böhlen MH; Gamper J (2011)
    Sequenced spatiotemporal aggregation (SSTA) is an important query for many applications of spatiotemporal databases, such as traffic analysis. Conceptually, an SSTA query returns one aggregate value for each individual ...
  • Capturing model-based ontology evolution at the instance level: The case of DL-Lite 

    Kharlamov E; Zheleznyakov D; Calvanese D (2013)
    Evolution of Knowledge Bases (KBs) expressed in Description Logics (DLs) has gained a lot of attention lately. Recent studies on the topic have mostly focused on so-called model-based approaches (MBAs), where the evolution ...
  • Analyzing Tool Usage to Understand to What Extent Experts Change Their Activities when Mentoring 

    Abrahamsson PK; Fronza I; Vlasenko J (Association for Computing Machinery, 2011)
    Automated In-Process Software Engineering Measurement and Analysis (AISEMA) systems represent a major advancement in tracking non-invasively the activities of developers. We have built on the top of an AISEMA system a model ...
  • The NPD Benchmark for OBDA Systems 

    Lanti D; Rezk M; Slusnys M; Xiao G; Calvanese D (CEUR Electronic Workshop Proceedings, 2014)
    In Ontology-Based Data Access (OBDA), queries are posed over a high-level conceptual view, and then translated into queries over a potentially very large (usually relational) data source. The ontology is connected to the ...
  • Personality Correlates for Digital Concert Program Notes 

    Tkalcic M; Ferwerda B; Hauger D; Schedl M (Springer, 2015)
    In classical music concerts, the concert program notes are distributed to the audience in order to provide background information on the composer, piece and performer. So far, these have been printed documents composed ...
  • Context awareness within mobile services 

    Höpken W; Fuchs M; Zanker M; Beer T (Helsinki University of Technology, 2006)
    Considering the usage context of an online service is an important requirement in order to reduce information overload and increase user acceptance, especially in the case of mobile services. This paper discusses approaches ...
  • Open Source technologies for visually impaired people 

    Boccacci P; Dodero GM; Carrega V (Springer, 2007)
    We describe two open source applications which we have experienced as very useful aids for the integration of people suffering from visual impairments, from hypovision to actual blindness. The first application is based ...
  • SCOTCH: Slicing and Coupling based Test to Code trace Hunter 

    Qusef A; Bavota G; Oliveto R; De Lucia A; Binkley D (IEEE, 2011)
    Recently, different methods and tools have been proposed to automate or semi-automate test-to-code traceability recovery. Among these, Slicing and Coupling based Test to Code trace Hunter (SCOTCH) exploits slicing and ...
  • High performance query answering over DL-Lite ontologies 

    Rodriguez-Muro M; Calvanese D (AAAI Press, 2012)
    Current techniques for query answering over DL-Lite ontologies have severe limitations in practice, since they either produce complex queries that are inefficient during execution, or require expensive data pre-processing. ...
  • Exchanging OWL 2 QL Knowledge Bases 

    Arenas M; Botoeva E; Calvanese D; Ryzhikov V (AAAI Press, 2013)
    Knowledge base exchange is an important problem in the area of data exchange and knowledge representation, where one is interested in exchanging information between a source and a target knowledge base connected through a ...
  • Towards a re-engineering method for web services architectures 

    Pahl C; Barrett R (WSCC, the Web Services Competence Center, 2004)
    Recent developments in Web technologies - in particular through the Web services framework - have greatly enhanced the flexible and interoperable implementation of service-oriented software architectures. Many older Web-based ...
  • Models of Agent Interaction based on Modal Logics 

    Baldoni M; Baroglio C; Marengo E; Patti V; Schifanella C (2011)

  • The complexity of explaining negative query answers in DL-Lite 

    Calvanese D; Ortiz M; Simkus M; Stefanoni G (AAAI Press, 2012)
    In order to meet usability requirements, most logic-based applications provide explanation facilities for reasoning services. This holds also for DLs, where research has focused on the explanation of both TBox reasoning ...
  • Toward a non invasive control of applications: A biomedical approach to failure prediction 

    Fronza I; Sillitti A; Succi G; Vlasenko J (SciTePress, 2011)
    Developing software without failures is indeed important. Still, it is also important to detect as soon as possible when a running application is likely to fail, so that corrective actions can be taken. Following the ...
