Выявление понятий и их взаимосвязей в рамках технологии контент-мониторинга

Приведены подходы к решению проблемы выявления фактографической информации из неструктурированных текстовых потоков. Описаны технологические решения, позволяющие извлекать из полнотекстовых документов такие понятия как фирмы, фамилии, географические названия и т.п., а также выявлять силу их взаимосвязей на основе применения двух алгоритмов. Первый из этих алгоритмов основывается на учете совместного вхождения понятий в одни и те же документы, а второй на учете общего для рассматриваемых понятий контекста.Наведено підходи до вирішення проблеми виявлення фактографічної інформації з неструктурованих текстових потоків. Описано технологічні рішення, що дозволяють добути з повнотекстових документів такі поняття як фірми, прізвища, географічні назви тощо, а також виявляти силу їхніх взаємозв’язків на базі застосування двох алгоритмів. Перший з цих алгоритмів базується на врахуванні спільного входження понять до одних і тих самих документів, а другий — на врахуванні загального для понять, що розглядаються, контексту.Approaches to the solution of a problem of revealing factual information from unstructured text flows are given. The technological solutions, allowing to take from text-through documents such concepts as a firm, a surname, place names, etc., and also to reveal force of their interrelations on the basis of application of two algorithms are described. The first of these algorithms is based on the account of joint concepts occurrence in the same documents, and the second one on the account of the context common for considered concepts

Cystic Fibrosis-Related Diabetes with strict glycaemic control is not associated with frequent intravenous antibiotics use for pulmonary infections

Aims: Pulmonary infections are more frequent in and associated with higher mortality in Cystic Fibrosis-Related Diabetes (CFRD) patients compared to CF patients without CFRD. Hyperglycaemia can lead to a higher vulnerability for infections. Aim of the study was to test whether the infection rate in well-controlled CFRD patients was similar to that in CF patients without CFRD. Methods: This is a retrospective six-year cohort analysis on a consecutive series of 138 CF patients. They were categorized in two groups with CFRD or without CFRD. Pulmonary infection frequency was defined as the number of intravenous (IV) antibiotic treatments. Clinical factors associated with infection frequency were collected. Results: CFRD was diagnosed in 54 (39%) CF patients of whom 44 (81%) achieved target value for glycaemic control (HbA1c 7.0% (≤53 mmol/mol)). Median frequency of IV antibiotics was 0 without CFRD and 3 episodes in patients with CFRD (rate ratio (RR) 2.9 (95% CI 1.6-5.2)). Multivariate analysis showed that frequency of IV antibiotics was significantly related to Pseudomonas aeruginosa colonization (RR 3.7) and lower lung function at baseline (RR 0.97) but not to CFRD by itself. Conclusions: In this cohort with overall strict glycaemic control, the frequency of IV antibiotics use was related to chronic infection and impaired lung function at baseline, but not to CFRD by itself. Although this study in itself does not prove beneficial effect of strict glycaemic control, it does emphasize the potential role of glycaemic control on infection frequency in CF patients
