  • 2ATAs make DLs easy 

    Calvanese D; De Giacomo G; Lenzerini M (CEUR-WS.org, 2002)
    In this paper we demonstrate that two-way alternating automata on infinite trees (2ATAs) provide a very elegant and effective formal tool for addressing reasoning in expressive DLs. Indeed, the encoding of a DL concept (to ...

  • A robust scheme for multilevel extendible hashing 

    Helmer, S; Neumann, T; Moerkotte, G (SpringerSpringer Verlag (Germany), 2003)
    Dynamic hashing, while surpassing other access methods for uniformly distributed data, usually performs badly for non-uniformly distributed data. We propose a robust scheme for multi-level extendible hashing, allowing ...
  • A-priori verification of web services with abduction 

    Alberti M; Chesani F; Gavanelli M; Lamma E; Mello P; Montali M (CILC, 2006)
    Although stemming from very different research areas, Multi-Agent Systems (MAS) and Service Oriented Computing (SOC) share common topics, problems and settings. A common problem is the need to formally verify the conformance ...
  • Abducing Compliance of Incomplete Event Logs 

    Chesani F; De Masellis R; Di Francescomarino C; Ghidini C; Mello P; Montali M; Tessaris S (Springer, 2016)
    The capability to store data about business processes execution in so-called Event Logs has brought to the diffusion of tools for the analysis of process executions and for the assessment of the goodness of a process model. ...
  • Abducing Workflow Traces: a General Framework to Manage Incompleteness in Business Processes (Short Paper) 

    Chesani F; De Masellis R; Di Francescomarino C; Ghidini C; Mello P; Montali M; Tessaris S (IOS Press, 2016)
    The capability to store data about Business Process executions in so-called Event Logs has brought to the identification of a range of key reasoning services (consistency, compliance, runtime monitoring, prediction) for ...
  • Abduction for specifying and verifying web service choreographies 

    Alberti, M; Chesani, F; Gavanelli, M; Lamma, E; Mello, M; Montali, M; Storari, S (AISC, 2006)
    Global choreographies have been recently proposed as a way for specifying the overall behaviour of a system composed of heterogeneous web services. In this work, we propose an abductive framework based on computational ...
  • An abductive framework for a-priori verification of web services 

    Alberti, M; Chesani, F; Gavanelli, M; Lamma, E; Mello, P; Montali, M (ACM Press, 2006)
    Although stemming from very different research areas, Multi-Agent Systems (MAS) and Service Oriented Computing (SOC) share common topics, problems and settings. One of the common problems is the need to formally verify the ...
  • Abductive logic programming as an effective technology for the static verification of declarative business processes 

    Montali, M; Torroni, P; Chesani, F; Mello, P; Alberti, M; Lamma, E (IOS Press / Polskie Towarzystwo Matematyczne, 2010)
    We discuss the static verification of declarative Business Processes. We identify four desiderata about verifiers, and propose a concrete framework which satisfies them. The framework is based on the ConDec graphical ...
  • Abductive Reasoning on Compliance Monitoring - Balancing Flexibility and Regulation
