  • Flexible Indexing of Repetitive Collections 

    Belazzougui, Djamal; Cunial, Fabio; Gagie, Travis; Prezza, Nicola; Raffinot, Mathieu
    In : (Springer, Turku, Finlande., 2017-06-07)
    Highly repetitive strings are increasingly being amassed by genome sequencing experiments, and by versioned archives of source code and webpages. We describe practical data structures that support count- ing and locating all the exact occurrences of a pattern in a repetitive text, by combining the run-length encoded ...
  • Representing the Suffix Tree with the CDAWG 

    Belazzougui, Djamal; Cunial, Fabio
    In : (Schloss Dagstuhl--Leibniz-Zentrum fuer Informatik, Varsovie, 2017-07-04)
    Given a string T, it is known that its suffix tree can be represented using the compact directed acyclic word graph (CDAWG) with e_T arcs, taking overall O(e_T+e_REV(T)) words of space, where REV(T) is the reverse of T, and supporting some key operations in time between O(1) and O(log(log(n))) in the worst case. This ...
  • New Technique to Deal With Verbose Queries in Social Book Search 

    Chaa, Messaoud; Nouali, Omar; Bellot, Patrice
    In : Rapports de recherche internes, (CERIST, Alger, 2017)
    Verbose query reduction and query term weighting are automatic techniques to deal with verbose queries.
  • New GPU-based Swarm Intelligence Approach For Reducing Big Association Rules Space 

    Djenouri, Youcef; Bendjoudi, Ahcène; Djenouri, Djamel; Belhadi, Asma; Nouali-Taboudjemat, Nadia
    In : Rapports de recherche internes, (CERIST, Alger, 2017-06-14)
    This paper deals with exploration and mining of association rules in big data, with the big challenge of increasing computation time. We propose a new approach based on meta-rules discovery that gives to the user the summary of the rules’ space through a meta-rules representation. This allows the user to decide about ...
  • An Approach to Improve Business Process Models Reuse Using LinkedIn Social Network 

    Khider, Hadjer; benna, Amel; Meziane, Abdelkrim; Hammoudi, Slimane
    In : (Springer International Publishing AG 2017, Editors: Rocha, Á., Correia, A.M., Adeli, H., Reis, L.P., Costanzo, S. (Eds.), Porto Santo Island, Portugal, 2017-04)
    Business process (BP) modeling is an important stage in Business Process Management (BPM) lifecycle. However, modeling BP from scratch is fallible task, complex, time-consuming and error prone task. One of the promising solutions to these issues is the reuse of BP models. BP reusability during the BP modeling stage can ...
