    • Author disambiguation in the YADDA2 software platform 

      Dendek, Piotr Jan; Wojewódzki, Mariusz; Bolikowski, Łukasz (Springer, 2013)
      SYNAT platform powered by the YADDA2 architecture has been extended with the Author Disambiguation Framework and the Query Framework. The former framework clusters occurrences of contributor names into identities of authors, ...
    • 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 ...
    • Hierarchical, multi-label classification of scholarly publications: modifications of ML-KNN algorithm 

      Łukasik, Michał; Kuśmierczyk, Tomasz; Bolikowski, Łukasz; Nguyen, Hung Son (Springer, 2013)
      One of the common problems when dealing with digital libraries is lack of classification codes in some of the documents. In the following publication we deal with this problem in a multi-label, hierarchical case of Mathematics ...
    • 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 ...
    • The Neumann problem in an irregular domain 

      Bolikowski, Łukasz; Gokieli, Maria; Varchon, Nicolas (EMS, Interfaces and Free Boundaries, 2010)
      We consider the stability of patterns for the reaction-diffusion equation with Neumann boundary conditions in an irregular domain in ℝN, N ≥ 2, the model example being two convex regions connected by a small ‘hole’ in their ...
    • 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, ...
    • Tagging Scientific Publications using Wikipedia and Natural Language Processing Tools. Comparison on the ArXiv Dataset 

      Łopuszyński, Michał; Bolikowski, Łukasz (Springer, 2014)
      In this work, we compare two simple methods of tagging scientific publications with labels reflecting their content. As a first source of labels Wikipedia is employed, second label set is constructed from the noun phrases ...
    • Towards a flexible author name disambiguation framework 

      Bolikowski, Łukasz; Dendek, Piotr Jan (2011-06-27)
      In this paper we propose a flexible, modular framework for author name disambiguation. Our solution consists of the core which orchestrates the disambiguation process, and replaceable modules performing concrete tasks. The ...
    • Towards robust tags for scientific publications from natural language processing tools and Wikipedia 

      Łopuszyński, Michał; Bolikowski, Łukasz (Springer, 2015)
      In this work, two simple methods of tagging scientific publications with labels reflecting their content are presented and compared. As a first source of labels, Wikipedia is employed. A second label set is constructed from ...
    • Workflow of metadata extraction from retro-born-digital documents 

      Tkaczyk, Dominika; Bolikowski, Łukasz (2011-06-27)
      In this work-in-progress report we propose a workflow for metadata extraction from articles in a digital form. We decompose the problem into clearly defined sub-tasks and outline possible implementations of the sub-tasks. ...
