    • Data complexity of query answering in description logics 

      Calvanese D; De Giacomo G; Lembo D; Lenzerini M; Rosati R (2013)
      In this paper we study data complexity of answering conjunctive queries over Description Logic (DL) knowledge bases constituted by an ABox and a TBox.  In particular, we are interested in characterizing the FOL-rewritability ...
    • Data integration in mediated service compositions 

      Pahl C; Zhu Y (Slovak Academy of Sciences, 2012)
      A major aim of the Web service platform is the integration of existing software and information systems. Data integration is a central aspect in this con- text. Traditional techniques for information and data transformation ...
    • Data mining technology for the evaluation of learning content interaction 

      Pahl, C (Association for the Advancement of Computing in Education, 2004)
      Interactivity is central for the success of learning. In e-learning and other educational multimedia environments, the evaluation of interaction and behaviour is particularly crucial. Data mining – a non-intrusive, objective ...
    • Database for contextual personalization 

      Košir A; Odić A; Kunaver M; Tkalčič M; Tasič J (2011)
      In recent years, research into user centric and personalized applications has focused on the utilization of contextual information about the situation in which the user is consuming the content item. However, there is no ...
    • DB-Nets: on The Marriage of Colored Petri Nets and Relational Databases 

      Montali M; Rivkin A (Springer, 2017)
      The integrated management of business processes and master data is being increasingly considered as a fundamental problem, by both the academia and the industry. In this position paper, we focus on the foundations of the ...
    • Dealing with explicit preferences and uncertainty in answer set programming 

      Confalonieri R; Nieves J; Osorio M; Vázquez-Salceda J (2012)
      In this paper, we show how the formalism of Logic Programs with Ordered Disjunction (LPODs) and Possibilistic Answer Set Programming (PASP) can be merged into the single framework of Logic Programs with Possibilistic Ordered ...
    • Decidability and Complexity of Fuzzy Description Logics 

      Baader F; Borgwardt S; Peñaloza R (2017)
      Fuzzy description logics (FDLs) have been introduced to represent concepts for which membership cannot be determined in a precise way, i.e., where instead of providing a strict border between being a member and not being ...
    • Deciding equivalences among conjunctive aggregate queries 

      Cohen, S; Nutt, W; Sagiv, Y (Association for Computing Machinery, 2007)
      Equivalence of aggregate queries is investigated for the class of conjunctive queries with comparisons and the aggregate operators count, count-distinct, min, max, and sum. Essentially, this class contains unnested SQL ...
