      Tkaczyk, Dominika; Czeczko, Artur; Rusek, Krzysztof; Bolikowski, Łukasz; Bogacewicz, Roman (ACM, 2012-06)
      The field of digital document content analysis includes many important tasks, for example page segmentation or zone classification. It is impossible to build effective solutions for such problems and evaluate their performance ...
    • Methodology for evaluating citation parsing and matching 

      Fedoryszak, Mateusz; Bolikowski, Łukasz; Tkaczyk, Dominika; Wojciechowski, Krzysztof (Springer, 2013)
      Bibliographic references between scholarly publications contain valuable information for researchers and developers involved with digital repositories. They are indicators of topical similarity between linked texts, impact ...
    • Comparing hierarchical mathematical document clustering against the Mathematics Subject Classification tree 

      Kuśmierczyk, Tomasz; Łukasik, Michał; Bolikowski, Łukasz; Nguyen, Hung Son (Springer, 2013)
      Mathematical publications are often labelled with Mathematical Subject Classification codes. These codes are grouped in a treelike hierarchy created by experts. In this paper we posit that this hierarchy is highly correlated ...
    • Data model for analysis of scholarly documents in the MapReduce paradigm 

      Kawa, Adam; Bolikowski, Łukasz; Czeczko, Artur; Dendek, Piotr Jan; Tkaczyk, Dominika (Springer, 2013)
      At CEON ICM UW we are in possession of a large collection of scholarly documents that we store and process using MapReduce paradigm. One of the main challenges is to design a simple, but effective data model that fits ...
    • Simulating Phase Transition Dynamics on Non-trivial Domains 

      Bolikowski, Łukasz; Gokieli, Maria (Lecture Notes in Computer Science, 2013)
      Our goal is to investigate the influence of the geometry and topology of the domain Ω on the solutions of the phase transition and other diffusion-driven phenomena in Ω, modeled e.g. by the Allen-Cahn, Cahn-Hilliard, ...
