Annotation Search: the FAST Way

Περιέχει το πλήρες κείμενοThis paper discusses how annotations can be exploited to develop information access and retrieval algorithms that take them into account. The paper proposes a general framework for developing such algorithms that specifically deals with the problem of accessing and retrieving topical information from annotations and annotated documents

MPEG-SCORM : ontologia de metadados interoperáveis para integração de padrões multimídia e e-learning

Orientador: Yuzo IanoTese (doutorado) - Universidade Estadual de Campinas, Faculdade de Engenharia Elétrica e de ComputaçãoResumo: A convergência entre as mídias digitais propõe uma integração entre as TIC, focadas no domínio do multimídia (sob a responsabilidade do Moving Picture Experts Group, constituindo o subcomitê ISO / IEC JTC1 SC29), e as TICE, (TIC para a Educação, geridas pelo ISO / IEC JTC1 SC36), destacando-se os padrões MPEG, empregados na forma de conteúdo e metadados para o multimídia, e as TICE, aplicadas à Educação a Distância, ou e-Learning (o aprendizado eletrônico). Neste sentido, coloca-se a problemática de desenvolver uma correspondência interoperável de bases normativas, atingindo assim uma proposta inovadora na convergência entre as mídias digitais e as aplicações para e-Learning, essencialmente multimídia. Para este fim, propõe-se criar e aplicar uma ontologia de metadados interoperáveis para web, TV digital e extensões para dispositivos móveis, baseada na integração entre os padrões de metadados MPEG-21 e SCORM, empregando a linguagem XPathAbstract: The convergence of digital media offers an integration of the ICT, focused on telecommunications and multimedia domain (under responsibility of the Moving Picture Experts Group, ISO/IEC JTC1 SC29), with the ICTE (the ICT for Education, managed by the ISO/IEC JTC1 SC36), highlighting the MPEG formats, featured as content and as description metadata potentially applied to the Multimedia or Digital TV and as a technology applied to e-Learning. Regarding this, it is presented the problem of developing an interoperable matching for normative bases, achieving an innovative proposal in the convergence between digital Telecommunications and applications for e-Learning, both essentially multimedia. To achieve this purpose, it is proposed to creating a ontology for interoperability between educational applications in Digital TV environments and vice-versa, simultaneously facilitating the creation of learning metadata based objects for Digital TV programs as well as providing multimedia video content as learning objects for Distance Education. This ontology is designed as interoperable metadata for the Web, Digital TV and e-Learning, built on the integration between MPEG-21 and SCORM metadata standards, employing the XPath languageDoutoradoTelecomunicações e TelemáticaDoutor em Engenharia ElétricaCAPE

Extending the DelosDLMS by the FAST Annotation Service

DelosDLMS [9] is a prototype of a next-generation Digital Library Management System (DLMS), jointly developed by partners of the EU-funded project DELOS 1 (a Network of Excellence on Digital Libraries). The goal of DelosDLMS is t

This paper describes the innovative annotation facilities of the CULTURA portal for digital humanties, which are aimed at improving the interaction of non specialist users and general public with cultural heritage contents. The annotation facilities are comprised by two modules: the FAST annotation service as back-end and the CAT Web front-end integrated in the CULTURA portal

Enriching Digital Cultural Heritage Collections via Annotations: The CULTURA approach

This paper introduces the main characteristics of the CULTURA project and of the IPSA collection, which constitutes one relevant use case presently in use in the CULTURA environment. We describe the innovative annotation features of the CULTURA portal for digital humanities; these features are aimed at improving the interaction of users with digital cultural heritage (CH) content. The annotation functions consist of two modules: the FAST annotation service as back-end and the CAT Web front-end integrated in the CULTURA portal. The annotation service also adds a semantic layer over the managed collections enhancing discoverability and interoperability capabilities of cultural heritage resources. A user-based evaluation of the environment has been carried out

Interacting with Digital Cultural Heritage Collections via Annotations: The CULTURA Approach

cultural collections that constitute the use cases presently in use in the CULTURA environment. A section on related work follows giving an account on efforts on the management of digital annotations that are pertinent and that have been considered. Afterwards the innovative annotation features of the CULTURA portal for digital humanities are described; those features are aimed at improving the interaction of non-specialist users and general public with digital cultural heritage content. The annotation functions consist of two modules: the FAST annotation service as back-end and the CAT Web front-end integrated in the CULTURA portal. The annotation features have been, and are being, tested with different types of users and useful feedback is being collated, with the overall aim of generalising the approach to diverse document collections and not only the area of cultural heritage

Digital Libraries: From Digital Resources to Challenges in Scientific Data Sharing and Re-Use

Digital libraries and digital archives are the information management systems for storing, indexing, searching, accessing, curating and preserving digital resources which manage our cultural and scientific knowledge heritage (KH). They act as the main conduits for widespread access and exploitation of KH related digital resources by engaging many different types of users, ranging from generic and leisure to students and professionals. In this chapter, we describe the evolution of digital libraries and archives over the years, starting from Online Public Access Catalog (OPAC), passing through monolithic and domain specific systems, up to service-oriented and component- based architectures. In particular, we present some specific achievements in the field: the DELOS Reference Model and the DelosDLMS, which provide a con- ceptual reference and a reference implementation for digital libraries; the FAST annotation service, which defines a formal model for representing and search- ing annotations over digital resources as well as a RESTful Web service imple- mentation of it; the NESTOR model for digital archives, which introduces an alternative model for representing and managing archival resources in order to enhance interoperability among archives and make access to them faster; and, the CULTURA environment, which favours user engagement over multimedia digital resources. Finally, we discuss how digital libraries and archives are a key technology for facing upcoming challenges in data sharing and re-use. Indeed, due to the rapid evolution of the nature of research and scientific publishing which are increasingly data-driven, digital libraries and archives are also progressively ad- dressing the issues of managing scientific data. In this respect, we focus on some key building blocks of this new vision: data citation to foster accessibility to scientific data as well as transparency and verifiability of scientific claims, re- producibility in science as an exemplar showcase of how all these methods are indispensable for addressing fundamental challenges, and keyword-based search over relation/structured data to empower natural language access to scientific data
