The instantiation of Omnipaper RDF prototype in the context of scientific publications

The purpose of this paper is to present an instance of the system developed in the OmniPaper project, regarding the mechanisms of distributed information retrieval. These mechanisms were developed for newspapers’ articles and they were then instantiated in the context of the scientific publication. Another goal concerns the use of a central metadatabase developed to accomplish the syndication of contents, through the RSS approach. Design/methodology/approach One of the steps of the system’s development was the definition of the metadata layer that supports the research and the navigation functionalities as well as the contents’ syndication. Several tasks were performed for the definition of the metadata layer, namely: (1) analysis of several metadata standard vocabularies; (2) Selection of the metadata elements; (3) Definition of an application profile and the RSS template; (4) Development of a metadatabase, through the use of a native RDF database management system to store the RSS descriptions of the scientific publications; (5) Implementation of the search and navigation processes developed in the prototype through the use of the RDFS version of the WordNet and the RDFS version of classification system of Association for Computing Machinery Computing Classification System (ACM CCS); finally (5) Tests and validation of all developed functionalities. Findings and value The OmniPaper system can be instantiated to other domains other than news published in newspapers. The RSS technology is well suited for handling the description of scientific contents. RDF records that were used in the OmniPaper RDF prototype were replaced by RSS. The subject and lexical thesauri were kept. This strong metadata layer allows the creation of several services that facilitate the conceptual search of scientific contents. Originality and value of paper This paper presents a system that uses a central metadatabase to support conceptual searching mechanisms. The metadatabase consists of RDF triples generated from: (1) RSS files that were, by their turn generated from OAI-PMH harvested metadata records; (2) a controlled vocabulary (ACM-CCS) implemented in RDF Schema and (3) an RDF version of WordNet. This is a solution for a value-added service for the scientific community that is fully based in state-of-the-art standard technologies and is fully open for integration with other systems. Moreover this could be implemented by journals to improve the current mechanisms used to access, distribute and disseminate the scientific research developments. Research limitations/implications (if applicable) The system implemented was tested but not evaluated in a real environment with specific users

The extension of the omnipaper system in the context of scientific publications

Today the Internet is an important information source, which facilitates the search and access to information contents on the Web. In fact, the Internet has become an important tool used daily by scholars in the development of their work. However the contents published on the Web increase daily and consequently difficult the identification of new contents published in various information sources. In this context the RSS technology introduces a new dimension in the access and dis-tribution mechanisms of new contents published by distributed information sources. In the scope of scientific contents the use of RSS technology helps the scholars to be up to date of new scientific resources provided by several and dis-tributed information sources. An instance of the OmniPaper RDF prototype has been developed in order to instantiate the mechanisms of distributed information retrieval investigated in the context of the news published in newspapers and use them in the context of scientific contents. In addition a central metadatabase was developed through the RSS approach, in order to enable the scientific content syn-dication. This paper intends to describe the steps involved in the development of the instantiation system of the OmniPaper RDF prototype

Алгоритмы анализа вторичных ресурсов в области физико-химической биологии

The significance of secondary sources for scientific research is substantiated. The long-term Information demand monitoring accomplished by the Library reveals the need for improving the processes of planning, coordination and assessment of science and research work. The library is able to facilitate this through providing access to science resources and databases within the subject scope of user inquiries. Based on the Russian and foreign publications, the current state of secondary information resources is analyzed. The recommendations on information analysis and preservation are given. The accumulated materials enabled to generate universal selection and reviewing criteria for the secondary information sources based on their completeness, relevancy, profile compliance, urgency, user friendliness. It is important that scientists and researchers are involved in building the system as well as the librarians providing and updating access to the resources. The researches at Physicochemical Biology Center are provided with the access to the secondary resources to meet their subject inquiries in prompt and efficient manner and to support scientometrical and patent researches.Обоснована важность вторичных ресурсов для научных исследований. Мониторинг информационных потребностей пользователей, проводимый сотрудниками библиотеки на протяжении многих лет, выявил заинтересованность ученых в оптимизации процессов планирования, координации и оценки научной деятельности. Помочь в этом может библиотека, наладив работу по раскрытию научных ресурсов и баз данных, отвечающих тематическим запросам пользователей. Сделан вывод о том, что отбором вторичных информационных ресурсов должна заниматься научная библиотека, которая не только располагает знаниями и опытом в работе с базами данных, но и хорошо изучила тематику и потребности научного учреждения. На примере российских и зарубежных публикаций изучено современное состояние рынка вторичных информационных ресурсов. Даны рекомендации по анализу и хранению информации. Собранный материал помог выработать универсальные критерии отбора и рецензирования вторичных информационных источников на основании их полноты, релевантности, профильности, актуальности, удобства использования. Ключевым моментом работы стало привлечение к созданию системы ученых – носителей знаний предметной области – и сотрудников библиотек, предоставляющих и корректирующих доступ к ресурсам. Для ученых Центра физико-химической биологии была выделена группа вторичных ресурсов, обеспечивающих быстрое и качественное удовлетворение тематических запросов, проведение наукометрических и патентных исследований
