    • E-connections of abstract description systems 

      Kutz O; Lutz C; Wolter F; Zakharyaschev M (Elsevier, 2004)
      Combining knowledge representation and reasoning formalisms is an important and challenging task. It is important because non-trivial AI applications often comprise different aspects of the world, thus requiring suitable ...

      Janes A; Sillitti A; Succi G (2013)
    • Effective mining of software repositories 

      D'Ambros M; Robbes R (IEEE Computer Society, 2011)
      With the advent of open-source, the Internet, and the consequent widespread adoption of distributed development tools, such as software configuration management and issue tracking systems, a vast amount of valuable information ...
    • Effects of asymmetric vertical disruptions on ITER components 

      Albanese R; Carpentieri B; Cavinato M; Minucci S; Palmaccio R; Portone A; Rubinacci G; Testoni P; Ventre S; Villone F (2015)
      This paper deals with the halo current distribution due to asymmetric vertical displacement events (VDEs) and the subsequent force distributions on the conducting structures in the ITER tokamak. Both the eddy and halo ...
    • The effects of SA8000 certification on firm performances: An empirical analysis 

      Orzes G (C.R.I.G., 2015)
      The impact of CSR practices on firm performances has been attracting considerable attention since late 1980s. No agreement has however been reached so far about this (positive, negative, or neutral) impact. This paper ...
    • Efficient Axiom Pinpointing in EL using SAT Technology 

      Manthey N; Peñaloza R; Rudolph S (CEUR, 2016)
      We propose a novel approach to axiom pinpointing based on a reduction to the SAT task of minimal unsatisfiable subformula enumeration, allowing highly optimized algorithms and data structures developed for SAT solving in ...
    • Efficient Computation of Parsimonious Temporal Aggregation 

      Mahlknecht G; Dignös A; Gamper J (Springer, 2015)
      Parsimonious temporal aggregation (PTA) has been introduced to overcome limitations of previous temporal aggregation operators, namely to provide a concise yet data sensitive summary of temporal data. The basic idea of PTA ...
    • An efficient elimination strategy for solving PageRank problems 

      Shen ZL; Huang TZ; Carpentieri B; Gu XM; Wen C (2017)
      In Web link structures, similar link distributions often occur, especially for pages from same hosts. For PageRank problems, similar in-link distributions of pages result in similar row patterns of the transition matrix. ...
    • Efficient Evaluation of Ad-Hoc Range Aggregates 

      Ammendola C; Böhlen MH; Gamper J (Springer, 2013)
      θ-MDA is a flexible and efficient operator for complex ad-hoc multi-dimensional aggregation queries. It separates the specification of aggregation groups for which aggregate values are computed (base table b) and the ...
    • Efficient event pattern matching with match windows 

      Cadonna B; Gamper J; Böhlen MH (ACM, 2012)
      In event pattern matching a sequence of input events is matched against a complex query pattern that specifies constraints on extent, order, values, and quantification of matching events. In this paper we propose a general ...
    • Efficient Handling of SPARQL OPTIONAL for OBDA 

      Xiao G; Kontchakov R; Cogrel B; Calvanese D; Botoeva E (Springer, 2018)
      OPTIONAL is a key feature in SPARQL for dealing with missing information. While this operator is used extensively, it is also known for its complexity, which can make it a challenge to evaluate queries with OPTIONAL ...
    • Efficient haplotype block recognition of very long and dense genetic sequences 

      Taliun D; Gamper J; Pattaro C (2014)
      Background: The new sequencing technologies enable to scan very long and dense genetic sequences, obtaining datasets of genetic markers that are an order of magnitude larger than previously available. Such genetic sequences ...
    • An efficient implementation of Reactive Event Calculus in SCIFF 

      Chesani F; Mello P; Montali M; Torroni P (2008)
      In this work, we propose a reactive version of the Event Calculus (EC) implemented on top of the SCIFF framework. Being reactive, such an implementation is able to dynamically update the status of fluents as events occur. ...
    • Efficient Itinerary Planning with Category Constraints 

      Bolzoni P; Helmer S; Wellenzohn K; Gamper J; Andritsos P (Association for Computing Machinery, 2014)
      We propose a more realistic approach to trip planning for tourist applications by adding category information to points of interest (POIs). This makes it easier for tourists to formulate their preferences by stating ...
    • Efficient Ontology-Based Data Integration with Canonical IRIs 

      Xiao G; Hovland D; Bilidas D; Rezk M; Giese M; Calvanese D (Springer, 2018)
      In this paper, we study how to efficiently integrate multiple relational databases using an ontology-based approach. In ontology-based data integration (OBDI) an ontology provides a coherent view of multiple databases, and ...
    • Efficient Reasoning With Consistent Proper Epistemic Knowledge Bases 

      Muise C; Miller T; Felli P; Pearce AR; Sonenberg L (ACM, 2015)
      Reasoning about the nested beliefs or knowledge of other agents is essential for many collaborative and competitive tasks. However, reasoning with nested belief (for example through epistemic logics) is computationally ...
