Возможности использования семантических информационных сервисов в музейном деле (на примере Музея истории ПетрГУ)

<p>В статье представлен авторский подход к развитию Музея истории Петрозаводского государственного университета на основе такого вида цифровых услуг для посетителей и музейных работников, как семантические информационные сервисы. Мотивом к реализации семантических сервисов в деятельности музея стала необходимость контекстного поиска информации в музейном фонде, а также использования потенциала посетителей в пополнении фонда ранее не задействованной в экспозиции информацией и новыми экспонатами, в том числе в электронном виде. </p><p>Предложены сценарии использования сервисов, показывающие, какую информационную поддержку можно обеспечить в музее для: 1) отбора экспонатов для новых экспозиций, 2) персонализированного предоставления информации об экспонатах посетителю, 3) получения от посетителей музея новой информации о хранимых музейных экспонатах, 4) пополнения фонда музея за счет новых экспонатов в электронном виде, полученных от посетителей.</p><p>Основой предлагаемых сервисов является создаваемая в музее семантическая сеть, объединяющая как сами экспонаты музейного фонда, так и иные информационные объекты, связанные с конкретными экспонатами и историей университета и образования в целом. Особым вниманием при создании онтологии семантической сети пользуются у авторов информационные объекты, связанные с повседневной жизнью университетского сообщества.</p><p>Представленный подход может быть интересен не только музейным работникам, но и профессиональным исследователям, заинтересованным в получении и изучении новых фактов из истории повседневной жизни образовательно-научной организации. <strong></strong></p>

A Semantic Information Services Framework for Sustainable WEEE Management Toward Cloud-Based Remanufacturing

Sustainable management of waste electrical and electronic equipment (WEEE) has attracted escalating concerns of researchers and industries. Closer information linking among the participants in the products's lifecycle should take place. How to interoperate among the distributed and heterogeneous information systems of various participants is a challenge faced. Targeting the cloud-based remanufacturing, this article aims to develop a semantic information services framework for sustainable WEEE management. In the proposed framework, an ontology based approach is developed to integrate and represent the lifecycle information from multiple local data sources within an information services provider. Meanwhile, a semantic information services management platform is introduced for the advertisement, matchmaking and retrieval of semantic information services. Some relevant techniques used to build the framework are introduced extensively. A demonstration case study on waste LCD TV is used to illustrate the effectiveness and significance of the proposed framework.

Grid Resource Ontology: a Keystone of Semantic Grid Information Service

This work presents a set of ontologies to facilitate the adoption of semantic technologies in Grid middleware and to provide a solid foundation for development of semantic Grid information services. The scope of the proposed ontologies includes a description of Grid resources and functionalities, interrelationship of all Grid components, subsystems and services, definition of administrative and usage policies, etc. The work also presents a set of tools to populate the provided Grid resource ontologies with real-data instance assertions by interrogating a traditional Grid information service and discusses the benefits of such representation of Grid resources.

Secure federation of semantic information services

A fundamental challenge for product-lifecycle management in collaborative value networks is to utilize the vast amount of product information available from heterogeneous sources in order to improve business analytics, decision support, and processes. This becomes even more challenging if those sources are distributed across multiple organizations. Federations of semantic information services, combining service-orientation and semantic technologies, provide a promising solution for this problem. However, without proper measures to establish information security, companies will be reluctant to join an information federation, which could lead to serious adoption barriers.Following the design science paradigm, this paper presents general objectives and a process for designing a secure federation of semantic information services. Furthermore, new as well as established security measures are discussed. Here, our contributions include an access-control enforcement system for semantic information services and a process for modeling access-control policies across organizations. In addition, a comprehensive security architecture is presented. An implementation of the architecture in the context of an application scenario and several performance experiments demonstrate the practical viability of our approach.

An ActOn-based semantic information service for Grids

We describe a semantic information service that aggregates metadata from a large number of information sources of a large-scale Grid infrastructure. It uses an ontology-based information integration architecture (ActOn) suitable for the highly dynamic distributed information sources available in Grid systems, where information changes frequently and where the information of distributed sources has to be aggregated in order to solve complex queries. These two challenges are addressed by a Metadata Cache that works with an update-on-demand policy and by an information source selection module that selects the most suitable source at a given point in time. We have evaluated the quality of this information service, and compared it with other similar services from the EGEE production testbed, with promising results.
