Процедура по обработки неструктурированных информационных ресурсов состоит из нескольких этапов: извлечение терминологических коллокаций, выбор признаков, классификация, тематическое аннотирование, кластеризация документов и аналитический информационный поиск. Методы автоматического извлечения терминологических коллокаций используются для формирования подмножества терминов предметной области. Множество терминологических коллокаций, выделяемое на заданной коллекции научных текстов, характеризует узкую предметную область этой коллекции. Автоматическое извлечение ключевых слов и терминологических коллокаций является основным этапом в задачах обработки естественного языка. Для автоматического извлечения терминологических коллокаций из научных текстов в данной работе рассматривается метод С-value. Установленное ограничение значения C-value позволит рассматривать только термины длиной более одного слова. Полученные таким образом термины-кандидаты формируют список n-грамм (биграммы, триграммы). Основная модификация метода, основанного на статистическом подходе, заключается в предварительном использовании морфологических шаблонов фильтров. Словосочетания, похожие на термины, извлекаются из текста с помощью метода C-value: проводится разделение текста; из текста извлекаются словосочетания, удовлетворяющие установленным условиям; для всех терминов-кандидатов, отобранных по установленному ограничению, создаются записи в базе данных. Методы выбора признаков применяются для сокращения размерности пространства признаков с целью формирования наиболее информативного состава. Выбор признаков способствует повышению эффективности обучения за счет уменьшения размера лексикона и точности классификации благодаря исключению шумовых признаков. Для удаления неинформативных терминов, т.е. для оценки важности терминов, выбран критерий χ2. Корпус документов для обработки собран из статей, опубликованных в журналах по различным направлениям.</p></abstract><trans-abstract xml:lang="en"><p>This paper discusses methods for identifying and selecting features when processing scientific information resources of a university. The procedure for processing unstructured information resources consists of several stages: the extraction of terminological collocations, the selection of features, classification, thematic annotation, clustering of documents and analytical information retrieval. Methods for automatic extraction of terminological collocations are used to form a subset of domain terms. The set of terminological collocations allocated on a given collection of scientific texts characterizes the narrow subject area of this collection. The automatic extraction of keywords and terminological collocations is the main stage in the tasks of processing natural language. For automatic extraction of terminological collocations from scientific texts in this paper the C-value method is considered. Setting a C-value value limit will only allow for terms longer than one word. The candidate terms thus obtained form a list of n-grams (bigrams, trigrams). The main modification of the method based on the statistical approach is the preliminary use of morphological filter patterns. Phrase-like phrases are extracted from the text using the C-value method: the text is divided; phrases that meet the established conditions are extracted from the text; for all candidate terms selected by the established restriction, records are created in the database. Methods of feature selection are used to reduce the dimension of feature space in order to form the most informative composition. The choice of traits contributes to improving the efficiency of learning by reducing the size of the lexicon and the accuracy of classification due to the elimination of noise signs. To remove non-informative terms, i. e. To assess the importance of the terms, the criterion was chosen. The body of documents for processing is assembled from articles published in journals in various fields.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метод С-Value</kwd><kwd>шаблоны терминов</kwd><kwd>N-граммная модель</kwd><kwd>триграммы</kwd><kwd>биграммы</kwd><kwd>критерий</kwd></kwd-group><kwd-group xml:lang="en"><kwd>C-Value method</kwd><kwd>term patterns</kwd><kwd>N-gram model</kwd><kwd>trigrams</kwd><kwd>bigrams</kwd><kwd>chi-squared test</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Pivovarova L.
