  • Modeling Parallel Applications in the MERPSYS Environment 

    Czarnul, Pawel (Gdańsk University of Technology, 2016)
    The chapter presents how to model parallel computational applications for which simulation of execution in a large-scale parallel or distributed envi- ronment is performed within the MERPSYS environment. Specifically, ...
  • DBpedia As a Formal Knowledge Base - An Evaluation 

    Boiński, Tomasz; Ambrożewicz, Adrian; Szymański, Julian (WSEAS, 2015)
    DBpedia is widely used by researchers as a mean of accessing Wikipedia in a standardized way. In this paper it is characterized from the point of view of questions answering system. Simple implementation of such system is ...
  • Efficient computations on clusters and grids 

    Czarnul, Paweł (Gdańsk University of Technology, Faculty of ETI, 2007)

  • Safety and Security Ontology 

    Boiński, Tomasz; Orłowski, Piotr; Szpryngier, Piotr (Gdańsk University of Technology, Faculty of ETI, 2012)
    Security and Safety Ontology as described in paper titled Extendable Security and Safety Ontology and in PhD Thesis of Tomasz Boiński.
  • Procedures for merging and alignment of domain ontologies 

    Boiński, Tomasz (Gdańsk University of Technology, Faculty of ETI, 2012)
    W trakcie prac nad rozprawą opracowano oryginalną metodę integracji ontologii na podstawie analizy leksykalnej jej elementów. Zaproponowany algorytm został zaimplementowany w postaci biblioteki w języku Java oraz włączony ...
  • Dynamic OWL Ontology Matching Using Lexical WordNet Based Measures 

    Boiński, Tomasz; Krawczyk, Henryk (Polskie Stowarzyszenie Zarządzania Wiedzą, 2012)
    Ontologies are often used as means of describing knowledge and domain of operation of modern applications. A need arises for ability to quickly match those ontologies to enable interoperability of such systems. The paper ...
  • Relation-based Wikipedia Search System for Factoid Questions Answering 

    Boiński, Tomasz; Brzeski, Adam (International Journal of Innovative Research in Computer and Communication Engineering, 2014)
    In this paper we propose an alternative keyword search mechanism for Wikipedia, designed as a prototype solution towards factoid questions answering. The method considers relations between articles for finding the best ...
  • Towards Facts Extraction From Texts in Polish Language 

    Boiński, Tomasz; Brzeski, Adam (International Journal of Innovative Research in Computer and Communication Engineering, 2014)
    The Polish language differs from English in many ways. It has more complicated conjugation and declination. Because of that automatic facts extraction from texts is difficult. In this paper we present basic differences ...
  • Knowledge Base Suitable for Answering Questions in Natural Language 

    Boiński, Tomasz; Szymański, Julian; Ambrożewicz, Adrian (WSEAS Press, 2014)
    This paper presents three knowledge bases widely used by researchers coping with natural language processing: OpenCyc, DBpedia and YAGO. They are characterized from the point of view of questions answering system. In this ...
  • Improvement of imperfect string matching based on asymmetric n-grams 

    Szymański, Julian; Boiński, Tomasz (Springer-Verlag Berlin Heidelberg, 2013-09)
    Typical approaches to string comparing treats them as either different or identical without taking into account the possibility of misspelling of the word. In this article we present an approach we used for improvement of ...
  • Extendable Safety and Security Ontology 

    Boiński, Tomasz; Orłowski, Piotr; Krawczyk, Henryk (Polskie Stowarzyszenie Zarządzania Wiedzą, 2012)
    Security plays more and more important role in our every day life and researchers and users of computer systems point out that a need arises for common, formalised model able to integrate different solutions. In this paper ...
  • Lexicon based algorithm for domain ontology merging and alignment 

    Boiński, Tomasz; Krawczyk, Henryk (INSTICC, Instytute for Systems and Technologies of Information, Control and Comunication, 2012)
    More and more systems contain some kind of knowledge describing their field of operation. Such knowledge in many cases is stored as an ontology. A need arises for ability to quickly match those ontologies to enable ...
  • Ontology engineering for system integration 

    Boiński, Tomasz; Orłowski, Piotr; Szpryngier, Piotr (Gdańsk University of Technology, Faculty of ETI, 2012)
