In this paper we consider the problem of web search results clustering in the Polish language, supporting our analysis with results acquired from an experimental system named Carrot. The algorithm we put into consideration – Suffix Tree Clustering has been acknowledged as being very efficient when applied to English. We present conclusions from its experimental application to Polish, indicating...

In this paper it is shown that the variety of mathematical models proposed, such as Nishiwaki [1], Recht and Ipson [2], Lambert and Jonas [3], Awerbuch and Bodrer [4], Nixdorf [5] and the modified analysis given by the author in earlier papers [6,7] almost all adhere to one basic form This shows clearly the relationship between the striking velocity WI, the residual velocity Wf, and the ballist...

The aim of this paper is to explore the relationship between wages, human capital and investment in financial assets with risky returns at the individual level. To explore this relationship from an international perspective, we analyse individual level data from the British Household Panel Survey, the German Socio-Economic Panel and the U.S. Panel Study of Income Dynamics. Our findings suggest ...

This paper reports a set of experiments motivated by the observation that the design of group decision processes is crucial to the success of electronic meeting room usage. Decision processes can be designed with more emphasis either on exchanging meanings (discussing issues) or exchanging artefacts (generating and structuring topics). Our problem is that, given a particular case to be discusse...

In single diffractive dissociation (SDD), pp → pX , one of the protons survives the interaction while the other dissociates in a hadronic system with invariant mass MX , separated from the first proton by a large rapidity interval devoid of particles. In the presence of a hard scale, such interactions may be regarded as the result of the exchange of a colourless object with vacuum quantum numbe...
