Designing a Metadata Model for Unstructured Document Management in Organizations
No full textAt present Document Management represents a critical problem for organizations, where a growing amount of information is produced in unstructured format. Metadata sets for Document Management addressing organizational needs are lacking, as most research efforts for Metadata specifications are focused on digital libraries and web communities requirements, rather than organizational ones. In this paper we propose a Metadata Model for Unstructured Document Management, called DMSML Document Management and Sharing Markup Language, which aims at modeling intrinsic properties of documents (e.g. title, author and keywords) as well as the relationships with the organizational context. Furthermore, while most metadata specifications don't rely on a well-developed data modeling methodology, our proposal is based on a three-layered data modeling approach, distinguishing a conceptual, logical and physical layer. This approach encourages understanding and easy adoption of metadata specifications among end users. At present we are developing a DMSML Framework prototype for validation purposes
A metadata-based approach for unstructured document management in organizations
No full textEffectively managing documents is a strategic requirement for every organization. Available document management systems (DMSs) often lack effective functions for automatic document management. One reason is that relevant information frequently is conveyed by unstructured documents, whose content cannot be easily accessed and processed by applications. This article proposes a metadata model, the DMSML (Document Management and Sharing Markup Language) to enable and to ease unstructured document management by supporting the design of DMSs. We argue that the extensive use of this metadata language will render organizational information explicit, promoting information reuse and interoperability in a more profitable way than what is guaranteed by proprietary DMSs. We also briefly depict the design and deployment phases of a Web-based DMS prototype based on DMSML. Our overall intent is to increase the awareness of what managers should account for when considering the possibility of adopting a DMS
Message-Based Service Brokering and Dynamic Composition in the SAI Middleware
No full textService-Oriented Computing (SOC) is a wide and
complex research area. Despite the huge effort in both industrial and academics initiatives, several challenges need to be addressed in order to effectively realize the SOC vision. One of the most relevant issues is the need of effective, flexible,
reliable, low cost solutions for dynamic service brokering and composition. This paper presents results of an ongoing work on the design and development of a service- and messageoriented
middleware for atomic and composite service
brokering, named SAI middleware. The SAI middleware offers
a set of features for service brokering and dynamic
composition, while also guaranteeing loose coupling between service providers and consumers and relaxing the prerequisites
for service providers to publish their capabilities in an interoperability domain. SAI dynamic composition is based on an Artificial Intelligence planning approach and on the
adoption of an ontology-based functional profile encoding
information for enabling automatic information extraction and combination in the service composition chain. Our main
contribution consists in addressing these issues in a holistic way, as required to effectively support the SOA vision in real application scenarios, while not optimizing single aspects yet
Context-aware Information Services to Support Tourist Communities
No full textSeveral context-aware applications exist that provide tourists with location-based content delivery
and interface adaptation to current activity. Our approach differs from previous ones as we consider
a tourist not only as a target for content delivery, but also as a source of valuable information,
useful for other tourists and service providers as well. This work describes a tourism context-aware
application that provides tourists on the move with proper mobile and location-based contextaware
services supporting community building and knowledge exchange. To this purpose, the
application includes a context-aware instant messaging service and a tourist service provider reputation
system, which supports tourists during decision-making processes. Here we describe main
issues related to the design and prototype implementation of the tourism context-aware application
and main results of user trials
An evaluation of Context-Aware Infomobility Systems
No full textThe delivery of real-time, context-aware, and personalized information to end-users for mobility support
is a high-priority objective in improving mobility services efficiency and effectiveness. This chapter
aims at providing an analysis of existing studies in the field of context awareness research targeted to
the infomobility application domain. The authors propose an evaluation framework for infomobility
services based on the elicitation of context information items and high-level requirements. The framework is applied to some relevant state-of-the art research works among personal navigation systems,
infomobility service integration frameworks and context-aware location-based communication platforms.
Evaluation results are discussed in order to highlight open research challenges in the infomobility application
domain
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
A Systemic and Cooperative Approach towards an Integrated Infomobility System at Regional Scale
No full textWith the term infomobility we refer to the broad range of Intelligent Transport Systems (ITS) information services. Despite the increasing efforts on development of infomobility services, it is recognized that they still show significant limitations in providing end users with reliable and seamless information. In this paper we argue that a systemic approach is needed to foster the growth of novel solutions for the delivery of integrated realtime and always-on infomobility services, to be seamlessly provided across different transport operators, modes and geographical areas. The proposed approach conceived and implemented within the ongoing SIMob research project in Tuscany Region (Italy) relies on the definition of an Open Working Environment, i.e. a socio-technical environment whose objective is to facilitate the co-operation of stakeholders to foster the growth of an integrated infomobility system at regional scale. Its main constituents are: a Cooperative Network of stakeholders, including regional and national subjects from Public Administrations, Enterprises and Research Bodies; an Architectural Framework, providing the reference technological baseline enabling the rapid configuration and deployment of different technological capabilities
A Metadata Model for the Design and Deployment of Document Management Systems
No full textThis work aims to address the issues of unstructured document management, by proposing a set of metadata: the DMSML (Document Management and Sharing Markup Language). DMSML represents a set of document properties, which are relevant to document management and render business and organizational information explicit, in a way which promotes reuse, interoperability and integration with heterogeneous systems
