    Applying semantics in the environmental domain: The TaToo project approach
    (Innovations in Sharing Environmental Observations and Information, 2011) Avellino, Giuseppe; Pariente Lobo, Tomás; Schimak, Gerald; Rizzoli, Andrea Emilio; Dihé, Pascal
    The EU FP7 TaToo project major aim is to bridge the resource discovery gap. This is a well know problem regarding, firstly, the difficulty of discovering resources available on the Web, secondly, the access and possibly the ‘visualisation’ of these resources once discovered. TaToo is trying to solve the problem through a framework (based on semantic concepts) able to store in a knowledge base, meta-information (or metadata) associated with resources. Meta-information is then used by TaToo during the resource discovery process. Meta-information is provided by end users while discovering resources or by resource owners and, as stored in a triplestore, it consists of RDF triples made of Domain Ontologies concepts. Meta-information knowledge base makes possible, together with a reasoner, a resource model for annotation, and a set of Domain Ontologies, a semantically-enhanced resource discovery process. The paper briefly shows the TaToo architecture focusing on the description of those components dealing with semantics. Then, it shows how semantics has been implemented, giving details on the Minimal Environmental Resource Model (MERM) and on the process of integrating Domain Ontologies to realise the ontology framework used in TaToo.

    The TaToo Portal – Tagging and Discovery within TaToo
    (Innovations in Sharing Environmental Observations and Information, 2011) Petronzio, Luca; Avellino, Giuseppe; Pariente Lobo, Tomás; Fuentes, Jose Maria; Yurtsever, Sinan
    A Web Portal represents an entry point on the Internet that allows users to access a centralized knowledge and information repository. In the TaToo project the Web Portal is the entry point to the Tagging and Discovery functionalities provided by the TaToo core framework. The aim is to supply a user front-end application which addresses user needs and that can be widely adopted across different domains and different locations. Moreover, a Web Portal benefits from the Web ubiquity increasing the number of possible users or the number of contacts from the same user. The users through the TaToo Web Portal are able to perform semantic searches for resources, to semantically annotate resources and to evaluate already existing resources or annotation associated with resources.

    The TaToo Semantic Case – Requirements, impacts and applications
    (Innovations in Sharing Environmental Observations and Information, 2011) Schimak, Gerald; Božic, Bojan; Kaufmann, Alexander; Peter-Anders, Jan; Dihé, Pascal; Rizzoli, Andrea; Pariente Lobo, Tomás; Avellino, Giuseppe
    Up today numerous semantic developments, starting from ontologies and leading to semantic applications in various (mostly financial or business) domains have been developed and put on the market. Still real suitable systems or application fostering the enrichment of environmental resources in order to make them better understandable and/or discoverable for a broader community are missing or have not be thought of yet. TaToo (Tagging Tools based on a semantic discovery framework, FP7 project, www.tatoo-project.eu ) intends to demonstrate how the enormous amount of environmental information can become better discoverable and understandable for a broad range of user, e.g. from environmental experts up to the man on the street. Clearly upfront to the definition, specification and implementation of the TaToo framework and tools the requirements with respect to environmental resources handled in TaToo (e.g. environmental data, services, applications etc.) have to be defined. TaToo deals with three scenarios, playing a two folded role. On the one hand they are key providers for challenging requirements but they are also the evaluation facility to prove (as domain experts) the results of project. The proposed paper will describe: a) the main categories of requirements (incl. the approach of requirements collection) written down e.g. for tagging, cross-domain annotation and discovery, meta-information, ontologies, etc. b) brief overview on the tools and services for tagging and discovery provided by the TaToo project c) description of Validation Scenario on Climate Twins Regions and its requirements as well as usage of TaToo developments d) the expected impact on Europeans Single Information Space and its environmental society/community
