The iMarine work plan for semantic services aims to initiate activities in 4 related areas:

1. Top-level Ontology
2. X-Search implementation and extension
3. iMarine semantic technology driven fact sheets
4. SKOS export

This page describes activities and planning at a global level, for specific implementation and development lans, please refer to specialized wiki-pages and TRAC tickets.

Abstract or Executive Summary

One of the 4 currently identified clusters in iMarine is 'semantics'. The term is sufficiently vague to enable the collection of requirements that operate on, or benfit from, 'semantic' technologies.

The work-plan is not domain specific, and technology neutral. It decribes how the iMarine Board can be involved in the specification of use-cases, data policies, and harmonization issues, to name a few issues.

Introduction and Background (The Problems)

The iMarine Board is responsible for the implementation of 2 Business Cases in the project, and brings a wealth of community expertise to the technical e-infrastructure. The EA-CoPCommunity of Practice. has needs to search over multiple resources, and extracted

The opportunity was presented and discussed at the imarine Board meeting in Rome (March 19-21), and later furtehr elaborated and discussed by project partners with EA-CoPCommunity of Practice. input.

Goals and Objectives (The Outputs)

The cluster discussion at the imarine board meeting was summarized by IRD (Julien Barde). Four goals were identified as products that can be delivered, for each of these, an initial set of objectives emerged that require further discussion.

Shared Ontology in the ecology domain

This use case is essential to the others, and should be discussed at the TCom in Greece in June.

• share a common model (reusing Dublin Core, SKOS, iCal, dcterms for spatial extent of IR, Darwin Core or OBOE..)
• integration of WORMS RDF triples related to taxon ranks (Darwin core) and others (parasites ?..). Need to figure out how to use their WS to do so.
• populate FLOD or Ecoscope from existing iMarine efforts (SDMX codelists)..

X-Search

FORTH AND FAO use case expanded with Ecoscope KB

• Searching engine improvement: could be a dedicated iMarine searching engine, by-product of the infrastructure,
  • X-Search deals with opensearch (see example of Terradue) so that it can brings in the loop metadata from the geospatial cluster,
  • Query expansion in the searching engine (multilingual, synonyms..with SKOS),
  • Clustering of results given by previous steps according to a list of entities chosen by users (before running the search). For example:
    • by taxon ranks,
    • by preys,
    • by geographic entities (on a map),
    • by kinds of Information Resources (IR): pictures, spatial information (layers, NetCDF.., WMC/Maps): similar to the geobrowser, databases..,
    • agents..
  • Highlighting results:
  • Highlights results (with same entities chosen by users or not),
  • Link to FLOD/Ecoscope KB: as done in the use case but with a link to related fact sheets,
  • Automated Tagging of IR (pdf, word, Web pages..) being compliant with our common model and reusing URIs of our KB. Same as AgroTagger with FORTH technology and possible interactions.

Common KB browser

• Facilitate common views (fact sheets) about entities from different KB (FLOD and Ecoscope),
• Connect raw data and analyzes (SDMX, OGC...)
• iMarine fact sheets blending pictures, layers, data from different partners..

SKOS export

The export / exposure of KB contents as SKOS would render them usable inside geonetwork or as a new thesaurus for agrotagger.
