Common Map of Academia (COMAC) is a system that keeps information about scientists and publications. It uses bibliographical information as a source of knowledge. In the article we show briefly this system. We present how we used that system for parts of Polish national CRIS: Polish national bibliography and newly created PolIndex – polish citation index. We present algorithms used for enhancin...

As word alignment is an important topic in statistical machine translation domain, bilingual dictionary extraction or linguistic information projection studies, a lot of attention has been dedicated to improve its quality. However not all languages are sufficiently represented in these examinations. In the following, we give a description of experiments with the Polish-English word alignment tr...

To what extent do Modern Greek, Polish, Swedish and American English similarly lexicalize action concepts, and how similar are the semantic associations between verbs denoting natural actions? Previous results indicate cross-linguistic stability between American English, Swedish, and Polish in verbs denoting basic human body movement, mouth movements, and sound production. The research reported...

The works of Polish philosophers, historians and classicists on the Euthyphro in the 19th century developed independently of any translations of the dialogue, even though two Polish translations of the dialogue were published (Platon 1858 and 1881) in the century1. The purpose of this paper is to provide evidence for a twofold interest that Polish readers had for Plato’s Euthyphro in the second...

This paper examines the portability of Stanford’s multi-pass rule-based sieve coreference resolution system to inflectional language (Polish) with a different annotation scheme. The presented system is implemented in BART, a modular toolkit later adapted to the sieve architecture by Baumann et al. The sieves for Polish include processing of zero subjects and experimental knowledge-intensive sie...

Our study aims at defining and analyzing voicing profiles of Polish and German sonorants in particular at tendencies of Polish [r] and German [R] in obstruent clusters. Thanks to the use of digital phonetic tools (IMS German Festival synthesis system) which extracted voicing profiles as a frame-by-frame basis in continuous speech, we were able to study all phonotactically possible contexts of s...

This paper describes a study on performance of existing unsupervised algorithms of text documents topical segmentation when applied to Polish plain text documents. For performance measurement five existing topical segmentation algorithms were selected, three different Polish test collections were created and seven approaches to text preprocessing were implemented. Based on quantitative results ...

We investigate the continuous model theory of ultrametric spaces of diameter ≤ 1. There is no universal Polish ultrametric space of diameter 1; but there is a Polish ultrametric space, Umax, taking distances in Q∩[0, 1], which is universal for all such Polish ultrametric spaces. We show that in the continuous theory of Umax, nonforking is characterized by a stable independence relation, which i...

We investigate two methods of identifying noun senses, based on clustering of lemmas and of documents. We have adapted to Polish the well-known algorithm of Clustering by Committee, and tested it on very large Polish corpora. The evaluation by means of a WordNet-based synonymy test used Polish wordnet (plWordNet 1.0). Various clustering algorithms were analysed for the needs of extraction of do...

Let _(x, !)r |!| p&2 ! be a p-Laplacian type operator and consider the Hodge decomposition _(x, Du)=D.+H, div H=0. A standard elliptic theory asserts that &D.&q (p&1) C &Du& p&1 q for all q>p&1. There has been considerable recent interest in the validity of the reverse estimate &Du& p&1 q C &D.&q (p&1) for q>p&1 in the regularity study of certain geometrical mappings. In this paper, we give a r...
