Proceedings of the 2014 Workshop on the Use of Computational Methods in the Study of Endangered Languages
The vocabularies of endangered languages surrounded by more prestigious languages are gradually shrinking in size due to the influx of borrowed items. It is easy to observe that in such languages, starting from some frequency rank, the lower the frequency of a vocabulary item, the higher the probability of that item being a borrowed one. On the basis of the data from the Beserman dialect of Udmurt, the article provides a model according to which the portion of borrowed items among the items with frequency ranks less than r increases logarithmically in r, starting from some rank r0, while for more frequent items, it can behave differently. Apart from theoretical interest, the model can be used to roughly predict the total number of native items in the vocabulary based on a limited corpus of texts.
The paper describes the structure and possible applications of the theory of K-representations (knowledge representations) in bioinformatics and in the development of a Semantic Web of a new generation. It is an original theory of designing semantic-syntactic analyzers of natural language (NL) texts with the broad use of formal means for representing input, intermediary, and output data. The current version of the theory is set forth in a monograph by V. Fomichov (Springer, 2010). The first part of the theory is a formal model describing a system consisting of ten operations on conceptual structures. This model defines a new class of formal languages – the class of SK-languages. The broad possibilities of constructing semantic representations of complex discourses pertaining to biology are shown. A new formal approach to developing multilingual algorithms of semantic-syntactic analysis of NL-texts is outlined. This approach is realized by means of a program in the language PYTHON.
This paper is devoted to the use of two tools for creating morphologically annotated linguistic corpora: UniParser and the EANC platform. The EANC platform is the database and search framework originally developed for the Eastern Armenian National Corpus (www.eanc.net) and later adopted for other languages. UniParser is an automated morphological analysis tool developed specifically for creating corpora of languages with relatively small numbers of native speakers for which the development of parsers from scratch is not feasible. It has been designed for use with the EANC platform and generates XML output in the EANC format.
UniParser and the EANC platform have already been used for the creation of the corpora of several languages: Albanian, Kalmyk, Lezgian, Ossetic, of which the Ossetic corpus is the largest (5 million tokens, 10 million planned for 2013), and are currently being employed in construction of the corpora of Buryat and Modern Greek languages. This paper will describe the general architecture of the EANC platform and UniParser, providing the Ossetic corpus as an example of the advantages and disadvantages of the described approach.
The book contains the proceedigs of the 18th International Conference on Automatic Processing of Natural Langage (France, Montpellie, 27th June - 1st July 2011).
This paper presents an algorithm that allows the user to issue a query pattern, collects multi-word expressions (MWEs) that match the pattern, and then ranks them in a uniform fashion. This is achieved by quantifying the strength of all possible relations between the tokens and their features in the MWEs. The algorithm collects the frequency of morphological categories of the given pattern on a unified scale in order to choose the stable categories and their values. For every part of speech, and for all of its categories, we calculate a normalized Kullback-Leibler divergence between the category’s distribution in the pattern and its distribution in the corpus overall. Categories with the largest divergence are considered to be the most significant. The particular values of the categories are sorted according to a frequency ratio. As a result, we obtain morphosyntactic profiles of a given pattern, which includes the most stable category of the pattern, and their values.
This paper is an overview of the current issues and tendencies in Computational linguistics. The overview is based on the materials of the conference on computational linguistics COLING’2012. The modern approaches to the traditional NLP domains such as pos-tagging, syntactic parsing, machine translation are discussed. The highlights of automated information extraction, such as fact extraction, opinion mining are also in focus. The main tendency of modern technologies in Computational linguistics is to accumulate the higher level of linguistic analysis (discourse analysis, cognitive modeling) in the models and to combine machine learning technologies with the algorithmic methods on the basis of deep expert linguistic knowledge.
A framework for fast text analysis, which is developed as a part of the Texterra project, is described. Texterra provides a scalable solution for the fast text processing on the basis of novel methods that exploit knowledge extracted from the Web and text documents. For the developed tools, details of the project, use cases, and evaluation results are presented.
This workshop is about major challenges in the overall process of MWE treatment, both from the theoretical and the computational viewpoint, focusing on original research related to the following topics:Manually and automatically constructed resources Representation of MWEs in dictionaries and ontologies MWEs in linguistic theories like HPSG, LFG and minimalism MWEs and user interaction Multilingual acquisition Multilingualism and MWE processing Models of first and second language acquisition of MWEs Crosslinguistic studies on MWEs The role of MWEs in the domain adaptation of parsers Integration of MWEs into NLP applications Evaluation of MWE treatment techniques Lexical, syntactic or semantic aspects of MWEs
The paper is focused on the study of reaction of italian literature critics on the publication of the Boris Pasternak's novel "Doctor Jivago". The analysys of the book ""Doctor Jivago", Pasternak, 1958, Italy" (published in Russian language in "Reka vremen", 2012, in Moscow) is given. The papers of italian writers, critics and historians of literature, who reacted immediately upon the publication of the novel (A. Moravia, I. Calvino, F.Fortini, C. Cassola, C. Salinari ecc.) are studied and analised.
In the article the patterns of the realization of emotional utterances in dialogic and monologic speech are described. The author pays special attention to the characteristic features of the speech of a speaker feeling psychic tension and to the compositional-pragmatic peculiarities of dialogic and monologic text.
