Data Challenges

Challenge #1

Enrich HTML web content with RDF annotation, and enable annotation-based document discovery

Background

Most information resources in the "Blue" domain were created without the exploitation by advanced search and discovery mechanisms in mind. They thus lack the semantic richness that would improve their visibility, usefulness, and quality.

One cost-effective opportunity to overcome this limitation may be the addition of RDFa to existing datasets. This can be achieved by a mechanism that extracts concepts from a html-text, aligns these with concepts from a semantic KB, and returns the uri's that can be attached to the source, either off-line, as header metadata, or in-line.

Proving that such a mechanisms can effectively enrich a 'flat' resource with interpretable rdf will present evidence for data owners in the "Blue" domain that they can add value to their resources with limited costs with the help of semantechnicians.

Objectives

We ask the hackathon participants to find a technical solution to enrich the factsheets of the FIGIS portal with annotations in RDFa format. The annotation will consist at least the URIs of the entities referenced in the factsheet, and of set of relevant relations provided with the datasets.

We ask the hackathon to:

1. GOAL: Provide an RDFa client to
   1. extract concepts from fact-sheets, e.g. accessing the fact-sheet content using the service provided here
   2. identify uri's from several KB's,
   3. create the RDF annotations, and
   4. expose these RDF annotations.
2. GOAL: Use the annotations produced at item one, as input to online search of factsheets (publication, GIS maps, images, statistical timeseries), to create enhanced discovery facility that complement the web page information content.
3. GOAL: Retrieve a set of fact-sheets via online search services.
4. GOAL: Write RDFa to these factsheets.

Challenges

TBD

Datasets

• FAO Species
  • Fact Sheets
• KB's:
  • TLO
  • FLOD

APIs

See below.

Challenge #2

Search Results presentation exploitation.

Search results regarding marine data could be enriched in order to provide advanced experience to the user. Derived information could be injected into results regarding identification of special keywords (related to the query), with results retrieved by OpenSearch and other external(?) datasources. Also exploration of the results could be improved from simple browsing into information discovery, providing accumulated information, filtering, suggestions etc.

Background

(Why this is relevant to blue-er world)

Objectives

1. We ask the hackathon participants to enrich the search results retrieved from iMarine Collections by identifying special keywords (related to the topic) with results retrieved from OpenSearch and other external(?) datasources.
2. We ask the hackathon participants to explore the database by performing a number of predefined queries and keep statistics on them in order to enhance the existing browsing methods

Challenges

TBD

Datasets

Ecoscope

APIs

gCube Search client

Challenge #3

Processing and Visualization of data sets

Exploit geolocation of real-world data in order to calculate and visualize geographical information and trends (i.e. migration of species). Support interactive map search over multiple sources, combined and enriched results. Search results will be presented on a map with possible options of clustering, filtering etc. User could also interact with results, like clicking on a result or location would show related results, helpful things etc.

FAO FLOD

• http://www.fao.org/figis/flod/

FLOD SPARQL endpoint

• http://www.fao.org/figis/flod/endpoint/flod (Jena Joseki)

Description

The Fisheries Linked Open Data (FLOD) stems from a rising trend initiative known as Linked Open Data. It is dedicated to create a dense network of relationships among the entities of the Fishery domains, and to programmatically serve them to semantic and traditional application environments. It started with the objective to identify and interlink equivalent codes from different code lists in use by FIGIS, in order to consolidate the information referenced by each different code, and then expanded to include external data source such as NAFO, EU, and ICCAT. Currently the FLOD network includes entities and relationships from the the domains of Marine Species, Water Areas, Land Areas, Exclusive Economic Zones. It serves software applications in the domain of statistics, and GIS. The FLOD content is exposed via either SPARQL endpoints (suitable for semantic applications), or via JAVA API to be embedded in consumers' application code.

Exploitation Example

Query for entities of kind:

• Gear types
• Vessel types
• Marine species
• Fishing Areas
• Statistical countries (Flagstate)
• Regional Fisheries Bodies

Ecoscope

Genesi DEC

http://www.genesi-dec.eu/

Description

The Genesi DEC project established establish open data and services access, allowing European and worldwide Digital Earth Communities to seamlessly access, produce and share data, information, products and knowledge. This creates a multi-dimensional, multi-temporal, and multi-layer information facility of huge value in addressing global challenges such as biodiversity, climate change, pollution and economic development.
