  • Scalable architectures for platform-as-a-service clouds: Performance and cost analysis 

    Xiong H; Fowley F; Pahl C; Moran N (Springer, 2014)
    Scalability is a significant feature of cloud computing, which ad-dresses to increase or decrease the capacities of allocated virtual resources at application, platform, database and infrastructure level on demand. We ...
  • Scalable collaborative filtering based on latent semantic indexing 

    Symeonidis P; Nanopoulos A; Papadopoulos A; Manolopoulos Y (AAAI, 2006)
    Nearest-neighbor collaborative filtering (CF) algorithms are gaining widespread acceptance in recommender systems and e-commerce applications. User ratings are not expected to be independent, as users follow trends of ...
  • Scalable link prediction in social networks based on local graph characteristics 

    Papadimitriou A; Symeonidis P; Manolopoulos Y (IEEE, 2012)
    Online social networks (OSNs) like Face book, My space, and Hi5 have become popular, because they allow users to easily share content or expand their social circle. OSNs recommend new friends to registered users based on ...
  • 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 ...
  • SCOTCH: Test-to-Code Traceability using Slicing and Conceptual Coupling 

    Qusef A; Bavota G; Oliveto R; De Lucia A; Binkley D (IEEE, 2011)
    Maintaining traceability links between unit tests and tested classes is an important factor for effectively managing the development and evolution of software systems. Exploiting traceability links helps in program ...
  • Secure incomplete multi-party computation for distributed constraint problems 

    Silaghi, M; Friedrich, G; Yokoo, M; Zanker, M (AAAI, 2006)
    The algorithms we propose here are simple but our contribution consists in identifying the simple guidelines required for a high level of privacy. Achieving the highest level of privacy for secrets used in a distributed ...
  • Self-organized learning in software factory: experiences and lessons learned 

    Wang X; Lunesu I; Rikkila J; Matta M; Abrahamsson P (Springer, 2014)
    Self-organization is one of the key agile principles. How it can be applied in an educational context is not explored extensively. In this paper we draw on relevant educational literature as the theoretical basis to ...
  • A Semantic Approach to Polystores 

    Kharlamov E; Mailis TP; Bereta K; Bilidas D; Brandt S; Jimènez-Ruiz E; Lamparter S; Neuenstadt C; Özcep ÖL; Soylu A; Svingos C; Xiao G; Zheleznyakov D; Calvanese D; Horrocks I; Giese M; Ioannidis YE; Kotidis Y; Möller R; Waaler A (IEEE Computer Society, 2016)
    In the database community Polystores is an emerging and promising approach for data federation that aims at designing a unified querying layer over multiple data models. In the Semantic Web community a similar in spirit ...
  • Semantic DMN: Formalizing Decision Models with Domain Knowledge 

    Calvanese D; Dumas M; Maggi FM; Montali M (Springer, 2017)
    The Decision Model and Notation (DMN) is a recent OMG standard for the elicitation and representation of decision models. DMN builds on the notion of decision table, which consists of columns representing the inputs and ...
  • Semantic DMN: Formalizing Decision Models with Domain Knowledge (Extended Abstract) 

    Calvanese D; Dumas M; Maggi FM; Montali M (CEUR Electronic Workshop Proceedings, 2017)
  • Semantic modelling of learning objects and instruction 

    Pahl C; Melia M (Springer, 2006)
    We introduce an ontology-based semantic modelling framework that addresses subject domain modelling, instruction modelling, and interoperability aspects in the development of complex reusable learning objects. Ontologies ...
  • Semantic Rule-Based Equipment Diagnostics 

    Mehdi G; Kharlamov E; Savkovic O; Xiao G; Güzel Kalayci E; Brandt S; Horrocks I; Roshchin M; Runkler TA (Springer, 2017)
    Industrial rule-based diagnostic systems are often data-dependant in the sense that they rely on specific characteristics of individual pieces of equipment. This dependence poses significant challenges in rule authoring, ...
  • Semantic Rules for Machine Diagnostics: Execution and Management 

    Kharlamov E; Savkovic O; Xiao G; Penaloza R; Mehdi G; Roshchin M; Horrocks I (ACM, 2017)
    Rule-based diagnostics of equipment is an important task in industry. In this paper we present how semantic technologies can enhance diagnostics. In particular, we present our semantic rule language sigRL that is inspired ...
  • Semantic web technology for web-based teaching and learning: A roadmap 

    Holohan E; Pahl C (LTSN Learning and Teaching Support Network, 2003)
    The World-Wide Web has become the predominant platform for computer-aided instruction. Contentorientation, access and interactive features have made the Web a successful technology. The Web, however, is still evolving. We ...
  • A semantical framework for the orchestration and choreography of web services 

    Pahl C; Zhu Y (Elsevier, 2005)
    Web Services are software services that can be advertised by providers and invoked by customers using Web technologies. This concept is currently carried further to address the composition of individual services through ...
  • Semantical Vacuity Detection in Declarative Process Mining 

    Di Ciccio C; Maggi FM; Montali M; Mendling J (Springer, 2016)
    A large share of the literature on process mining based on declarative process modeling languages, like declare, relies on the notion of constraint activation to distinguish between the case in which a process execution ...
