      Güzel Kalayci E; Xiao G; Ryzhikov V; Kalayci TE; Calvanese D (ACM, 2018)
      We present Ontop-temporal, an extension of the ontology-based data access system Ontop for query answering with temporal data and ontologies. Ontop is a system to answer SPARQL queries over various data stores, using ...
    • Attributed Description Logics: Ontologies for Knowledge Graphs 

      Krötzsch M; Marx M; Ozaki A; Thost V (Springer, 2017)
      In modelling real-world knowledge, there often arises a need to represent and reason with meta-knowledge. To equip description logics (DLs) for dealing with such ontologies, we enrich DL concepts and roles with finite sets ...
    • From MVPs to Pivots: A Hypothesis-Driven Journey of Two Software Startups 

      Khanna D; Nguyen DA; Wang X (Springer, 2018)
      Software startups have emerged as an interesting multiper-spective research area. Inspired by Lean Startup, a startup journey can be viewed as a series of experiments that validate a set of business hypotheses an entrepreneurial ...
    • On Help and Interpersonal Control 

      Bottazzi E; Troquard N (Springer, 2015)
      Help is not much considered in the literature of analytic social philosophy. According to Tuomela (Cooperation – a philosophical study, Springer, 2000), when a helps an agent b (1) a contributes to the achievement of b’s ...
    • Towards Trustworthy Financial Reports Using Blockchain 

      D’Atri G; Le VT; Pahl C; El Ioini N (IARIA, 2019)
      The need to develop a system for dealing with the transparency analysis of financial reports has pushed companies to look for possible solutions to store their data in a reliable and trustworthy database, that enables all ...
    • An Exploration of Cognitive Shifting in Writing Code 

      Fronza I; Hellas A; Ihantola P; Mikkonen T (ACM, 2019)
      Programming is considered a demanding task that requires focusing on detail at code level. Students learning to program need to learn to think like a programmer, which involves coming up with plans needed to solve problems, ...
    • The design of TurnTalk for the scaffolding of balanced conversations in groups of children 

      Melonio A; Rizvi M (Springer, 2017)
      The proper management of conversation among children is pivotal for any group activity with them. Socio-emotional learning curricula developed experimented activities for teaching children conversation skills, which can ...
    • Prompter: Turning the IDE into a self-confident programming assistant 

      Ponzanelli L; Bavota G; Di Penta M; Oliveto R; Lanza M (2016)
      Developers often require knowledge beyond the one they possess, which boils down to asking co-workers for help or consulting additional sources of information, such as Application Programming Interfaces (API) documentation, ...
    • Planning for a Single Agent in a Multi-Agent Environment Using FOND 

      Muise C; Felli P; Miller T; Pearce AR; Sonenberg L (IJCAI/AAAI Press, 2016)
      Single-agent planning in a multi-agent environment is challenging because the actions of other agents can affect our ability to achieve a goal. From a given agent's perspective, actions of others can be viewed as ...
    • Fast Computation of Continental-Sized Isochrones 

      Bolzoni P; Helmer S; Lachish O (Springer, 2016)
      We propose an approach to speed up the computation of isochrones, which are maps showing the reachability of locations given a starting point and a time constraint. The core idea of our technique is to materialize large ...
    • Lossless Selection Views under Conditional Domain Constraints 

      Feinerer I; Franconi E; Guagliardo P (2015)
      A set of views defined by selection queries splits a database relation into sub-relations, each containing a subset of the original rows. This decomposition into horizontal fragments is lossless when the initial relation ...
    • CoPMod: Support for Construction Process Modeling 

      Marengo E; Nutt W; Perktold M (CEUR-WS, 2018)
      CoPMod is a proof-of-concept tool for supporting a collaborative construction process modeling approach that has been developed in a research project and tested in real construction projects. In the tests, the approach was ...
    • Cooperation wordle using pre-attentive processing techniques 

      Fronza I; Janes A; Sillitti A; Succi G; Trebeschi S (IEEE, 2013)
      Developer turnover can result in a major problem when developing software. Senior developers leaving the team cause a loss of knowledge; on the other hand, new developers need some time to become fully productive. In this ...
    • “Failures” to be celebrated: an analysis of major pivots of software startups 

      Bajwa S; Wang X; Nguyen Duc A; Abrahamsson P (Springer New York LLC, 2017)
      In the context of software startups, project failure is embraced actively and considered crucial to obtain validated learning that can lead to pivots. A pivot is the strategic change of a business concept, product or the ...
