This paper presents a new interpretation for Zipf-Mandelbrot's law in natural language which rests on two areas of information theory. Firstly, we construct a new class of grammar-based codes and,… (More)

This paper discusses two new procedures for extracting verb valences from raw texts, with an application to the Polish language. The first novel technique, the EM selection algorithm, performs… (More)

The article discusses two mutually-incompatible hypotheses about the stochastic mechanism of the generation of texts in natural language, which could be related to entropy. The first hypothesis, the… (More)

Hilberg (1990) supposed that finite-order excess entropy of a random human text is proportional to the square root of the text length. Assuming that Hilberg's hypothesis is true, we derive Guiraud's… (More)

Subword complexity is a function that describes how many different substrings of a given length are contained in a given string. In this paper, two estimators of block entropy are proposed, based on… (More)

The relaxed Hilberg conjecture states that the mutual information between two adjacent blocks of text in natural language grows as a power of the block length. The present paper reviews recent… (More)

The aim of this article is to develop a discussion of Menzerath’s law from the point of view of information theory. More precisely, we shall seek for links between the law and the recently abstracted… (More)

We introduce an implementation of a plain trigram part-of-speech tagger which appears to work well on Polish texts. At this moment the tagger achieves 9.4% error rate, which makes it signficantly… (More)

This paper deals with a problem of an application of an MT method developed for a pair of very closely related languages to a pair of languages whose degree of relatedness (and thus also the degree… (More)

Using a new universal distribution called switch distribution, we reveal a prominent statistical difference between a text in natural language and its unigram version. For the text in natural… (More)
