VIRTUOSO projects aims at providing European Security stakeholders with a toolkit based on an open-source-software framework and a set of advanced information processing tools. This toolkit will allow building end-user oriented applications: - Ranging from open source collection to decision support - Providing at each step actionable, rated, validated information - Integrated in an open framework in order to accept existing or future tools - Compliant with legal & ethical issues The VIRTUOSO toolkit will increase user productivity by automating time consuming activities and eliminating current bottlenecks that will be accurately identified with a large panel of users. Due to numerous application domains and the various size of the resources needed by the application of such a toolkit, this toolkit will demonstrate high level scalability, from mobile to High Power Computing systems. Cooperation of various European agencies will be addressed by proposing a standard, open and Interoperable toolkit, facilitating storage and sharing of information. Guidelines will be proposed.

There is an increasing presence of structured data due to the adoption of Linked data principles on the web. At the same time, web users have different skills and want to be able to interact with Linked datasets in various manner, such as asking questions in natural language. This paper proposed a first implementation of Query Answering system (QA) applied to the Linked Open Vocabularies (LOV) catalogue, mainly focused on metadata information retrieval. The goal is to provide to end users yet another access to metadata information available in LOV using natural language questions.

Purpose: The paper seeks to analyze the health of the vocabulary ecosystem in terms of requirements, addressing its various stakeholders such as maintainers of linked open vocabularies, linked data providers who use those vocabularies in their data and memory institutions which, it is hoped, will eventually provide for the long-term preservation of vocabularies. Design/methodology/approach: This paper builds on requirements formulated more tersely in the DCMI generic namespace policy for RDF vocabularies. The examination of requirements for linked open vocabularies focuses primarily on property-and-class vocabularies in RDFS or OWL (sometimes called metadata element sets), with some consideration of SKOS concept schemes and Dublin Core application profiles. It also discusses lessons learned through two years of development of the linked open vocabularies (LOV), of which main features and key findings are described. Findings: Key findings about the current practices of vocabulary managers regarding metadata, policy and versioning are presented, as well as how such practices can be improved to ensure better discoverability and usability of RDF vocabularies. The paper presents new ways to assess the links and dependencies between vocabularies. It also stresses the necessity and importance of a global governance of the ecosystem in which vocabulary managers, standard bodies, and memory institutions should engage. Research limitations/implications: The current paper is focused on requirements related to a single type of vocabulary but could and should be extended to other types such as thesauri, classifications, and other semantic assets. Practical implications: Practical technical guidelines and social good practices are proposed for promotion in the Vocabulary Ecosystem (for example, by vocabulary managers). Originality/value: This paper brings together the research and action of several important actors in the vocabulary management and governance field, and is intended to be the basis of a roadmap for action presented at the Dublin Core conference of September 2013 in Lisbon (DC 2013). © Emerald Group Publishing Limited.

The SeaBILLA proposal aims to 1) define the architecture for cost-effective European Sea Border Surveillance systems, integrating space, land, sea and air assets, including legacy systems; 2) apply advanced technological solutions to increase performances of surveillance functions; 3) develop and demonstrate significant improvements in detection, tracking, identification and automated behaviour analysis of all vessels, including hard to detect vessels, in open waters as well as close to coast. SeaBILLA is based on requirements for Sea Border Surveillance defined by experienced operational users. These requirements have been transformed into Scenarios, included in Annex to this proposal, representative of gaps and opportunities for fruitful cooperative information exchange between Members States a) for fighting drug trafficking in the English Channel; b) for addressing illegal immigration in the South Mediterranean; c) for struggling illicit activities in open-sea in the Atlantic waters from Canary Islands to the Azores; in coherence with the EU Integrated Maritime Policy, EUROSUR and Integrated Border Management, and in compliance with Member States sovereign prerogatives. The project will provide concrete added value and benefits for users, by providing a solution that can be implemented at national and EU level to increase effectiveness, pool resources and address Maritime Security and Safety challenges; for world competitiveness of EU industries, by increasing knowledge and reducing risks for future product investments; for European citizens, by providing effectively deployable solutions for law enforcement along the European sea borders. SeaBILLA will be carried out by a reliable team of major European system integrators, technology providers and leading research organizations, establishing strong links with several EU and national projects and assuring worldwide exploitation of project results.

Domain ontologies are a central component in the Virtuoso demonstrator, a system that captures, analyzes and aggregates open news sources in order to achieve an information position that supports complex decision processes in the context of border control. However, maintenance of such an ontology is a challenging task. We demonstrate a text processing pipeline that supports domain experts in maintaining the domain ontology. The system facilitates the maintenance by generating candidate concepts that should be added to the ontology. Some initial tests have been carried out with filtering candidate concepts from a domain specific news feed. © 2013 IEEE.

Unlike most approaches in the field of temporal expressions annotation, we consider that temporal adverbials could be relevant units from the point of view of Information Retrieval. We present here the main principles of our semantic modeling approach to temporal adverbial units. It comprises two steps: functional modeling (using a small number of basic operators) and referential modeling (using calendar intervals). In order to establish relationships between calendar zones, our approach takes into account not only the calendar values involved in adverbial units but also the semantics of prepositional phrases involved in these units. Through a first experiment, we show how Information Retrieval systems could benefit from indexing calendar expressions in texts, defining relevance scores that combine keywords and temporal ranking models. © 2011 Springer-Verlag Berlin Heidelberg.

Developing ontologies, by reusing already available and wellknown ontologies, is commonly acknowledge to play a crucial role to facilitate inclusion and expansion of the Web of Data. Some recommendations exist to guide ontologists in ontology engineering, but they do not provide guidelines on how to reuse vocabularies at low fine grained, i.e., reusing specific classes and properties. Moreover, it is still hard to find a tool that provides users with an environment to reuse terms. This paper presents ProtégéLOV, a plugin for the ontology editor Protégé, that combines the access to the Linked Open Vocabularies (LOV) during ontology modeling. It allows users to search a term in LOV and provides three actions if the term exists: (i) replace the selected term in the current ontology; (ii) add the rdfs:subClassOf or rdfs:subPropertyOf axiom between the selected term and the local term; and (iii) add the owl:equivalentClass or owl:equivalentProperty between the selected term and local term. Results from a preliminary user study indicate that ProtégéLOV does provide an intuitive access and reuse of terms in external vocabularies. © Springer International Publishing Switzerland 2015.

We discuss in this paper, semantic web methodologies, best practices and recommendations beyond the IERC Cluster Semantic Interoperability Best Practices and Recommendations (IERC AC4). The semantic web community designed best practices and methodologies which are unknown from the IoT community. In this paper, we synthesize and highlight the most relevant work regarding ontology methodologies, engineering, best practices and tools that could be applied to Internet of Things (IoT). To the best of our knowledge, this is the first work aiming at bridging such methodologies to the IoT community and go beyond the IERC AC4 cluster. This research is being applied to three uses cases: (1) the M3 framework assisting IoT developers in designing interoperable ontology-based IoT applications, (2) the FIESTA-IoT EU project encouraging semantic interoperability within IoT, and (3) a collaborative publication of legacy ontologies. © 2015 IEEE.

This paper presents a conceptual graph formalism called simple graph boolean formulas that extends the with boolean connectors. This formalism is used to define categories of objects in a classification service that can be turned into a legal content management system. We define the of graph boolean formulas, present two decidable fragments of this formalism (relying on the first order logic BSR and guarded fragments), and describe the functional architecture of a generic classification service that can be used in the legal domain. © 2012 Springer-Verlag.
