We present a direct method of construction of a morphosyntactic guesser for Polish, which is a program producing morphosyntactic descriptions for word forms unknown to the morphological analyser. The core of the method is the construction of a statistical a tergo index, in which pseudo-suffixes (endings) extracted by a statistical tree define morpho-syntactic properties of corresponding word fo...

Perspective I n this issue of PLoS Medicine, Madelyn Hsiao-Rei Hicks and Michael Spagat propose a new quantitative tool [1] in the emerging field of human security sciences [2]. Quantitative data about people's insecurity can lead to objective knowledge about many of the contexts of violence in the world today. Thus developing quantitative tools for use in this domain is important. Hicks and Sp...

This paper presents a statistical analysis of Tehran Price Index (TePIx) for the period of 1992 to 2004. The results present asymmetric property of the return distribution which tends to the right hand of the mean. Also the return distribution can be fitted by a stable Lévy distribution and the tails are very fatter than the gaussian distribution. We estimate the tail index of the TePIx returns...

Document-centric static index pruning methods provide smaller indexes and faster query times by dropping some within-document term information from inverted lists. We present a method of pruning inverted lists derived from the formulation of unigram language models for retrieval. Our method is based on the statistical significance of term frequency ratios: using the two-sample two-proportion (2...

When an innovative biologic product goes off patent, biopharmaceutical or biotechnological companies may file an application for regulatory approval of biosimilar products. Unlike small molecule drug products, biosimilars are not exact copies of their brand-name counterpart, and they are usually very sensitive to changes in environmental factors and have greater variabilities due to their compl...

In this paper, we will discuss how to use Maple programming to empirically investigate the asymptotic normality of the generalized Hirsch citation index (alias size of Durfeee rectangle) with respect to the uniform distribution on the sample space of integer partitions of n. All the results of this article were obtained using Maple programs, and is available at: http://math.rutgers.edu/ hbl15/e...

In this paper we describe the development of the Web Index linked data portal that represents statistical index data and computations. The Web Index is a multi-dimensional measure of the World Wide Web’s contribution to development and human rights globally. It covers 81 countries and incorporates indicators that assess several areas like universal access; freedom and openness; relevant content...

The creation and use of quantitative indexes is a widely accepted practice that has been applied to numerous domains like Bibliometrics (Impact factor), research and academic performance (H-Index or Shanghai rankings), cloud computing (Global Cloud Index, by CISCO), etc. We consider that those indexes and rankings could benefit from a Linked Data approach where the rankings could be seen, track...
