Application of Topic Models to Judgments from Public Procurement Domain
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 ...
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.
Molecular dynamics of ribosomal elongation factors G and Tu
(Springer Nature, 2011)
Translation on the ribosome is controlled by external factors. During polypeptide lengthening, elongation factors EF-Tu and EF-G consecutively interact with the bacterial ribosome. EF-Tu binds and delivers an aminoacyl-tRNA ...
Comparing hierarchical mathematical document clustering against the Mathematics Subject Classification tree
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 ...
Local existence and uniqueness of solutions to one-dimensional tumor invasion model
In the present paper, we propose a modified tumor invasion model which was originally proposed in Chaplain and Anderson (2003) . And we show the local existence and uniqueness of solutions to approximate systems of ...
Towards a flexible author name disambiguation framework
(Masaryk University Press, 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 ...
Workflow of metadata extraction from retro-born-digital documents
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. ...
Computational study of structural and elastic properties of random AlGaInN alloys
(IOP Publishing, 2010-04-26)
In this work we present a detailed computational study of the structural and elastic properties of cubic AlGaInN alloys in the framework of Keating valence force field model, for which we perform an accurate parametrization ...
The Neumann problem in an irregular domain
(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 ...
