Electronic transfer contribution in adsorption of silicon at SiC(0001) surface – density functional theory (DFT) study
(preprint, 2015)Physical properties of SiC(0001) surface under various coverage by Si adatoms was studied using density functional theory (DFT) calculations. The clean SiC(0001) surface has the Fermi level pinned by Si broken bond state ... -
Towards robust tags for scientific publications from natural language processing tools and Wikipedia
(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 ... -
Qualitative behaviour and numerical approximation of solutions to conservation laws with non-local point constraints on the flux and modeling of crowd dynamics at the bottlenecks
(2015)In this paper we investigate numerically the model for pedestrian traffic proposed in [B. Andreianov, C. Donadello, M.D. Rosini, Crowd dynamics and conservation laws with nonlocal constraints and capacity drop, Mathematical ... -

Tagging Scientific Publications using Wikipedia and Natural Language Processing Tools. Comparison on the ArXiv Dataset
(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 ... -
Unsupervised Keyword Extraction From Polish Legal Texts
(Springer, 2014)In this work, we present an application of the recently pro- posed unsupervised keyword extraction algorithm RAKE to a corpus of Polish legal texts from the field of public procurement. RAKE is essen- tially a language ... -
Application of Topic Models to Judgments from Public Procurement Domain
(IOSPress, 2014-12)In this work, automatic analysis of themes contained in a large corpora of judgments from public procurement domain is performed. The employed technique is unsupervised latent Dirichlet allocation (LDA). In addition, it ... -

Simulating Phase Transition Dynamics on Non-trivial Domains
(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, ... -
An Ocean of Information. Information overload faced by Internet users
(Polska Akademia Nauk, 2011)As the amount of online content grows, Internet users’ attention span decreases. This brings an acute need for social and technological solutions that enable users to select the most important and relevant information. -
The Burden of Big Data
(Polska Akademia Nauk, 2012)New technologies are making it possible to gather and process huge amounts of data. This opens up fascinating possibilities as well as new challenges; it could also lead to a shift in the role and nature of science itself. -
Kapitał społeczny i otwartość jako podstawa innowacyjności
(PARP, 2013-02-08)Jednym z najistotniejszych pytań dotyczących innowacyjności w Polsce jest to, dlaczego mimo wysokiego kapitału ludzkiego, dużej liczby młodych i relatywnie dobrze wykształconych osób, innowacyjność jest w naszym kraju ... -
Jak skłonić do udziału w badaniach internetowych: zwiększanie realizacji próby
(Wydawnictwo Naukowe Scholar, 2007-11-22)Prowadzenie badań ankietowych i eksperymentalnych w Internecie jest coraz popularniejsze, ale ich autorzy muszą borykać się z problemami małej motywacji do udziału i niskiego stopnia realizacji próby (response rate). ... -

(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, ... -
Methodology for evaluating citation parsing and matching
(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 ... -
Data model for analysis of scholarly documents in the MapReduce paradigm
(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 ... -
Comparing hierarchical mathematical document clustering against the Mathematics Subject Classification tree
(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 ...
