TLO-Development activity

General Description

This activity concerns with the development of a Top Level Ontology (for short TLO) that will integrate the concepts currently existing in marine-domain knowledge bases (in particular FLOD and ECOSCOPE knowledge bases). The TLO-Development activity is dived into six sub-activities (or Tasks) and related to each other as shown in the diagram in Fig 1.

Methodology

It is based on an Iterative and Incremental development approach. As such, one iteration will involve all the above tasks that are described here http://wiki.i-marine.eu/index.php/Top_Level_Ontology. All the iterations will be accurately described and TLO Modules/ Versions will be delivered in each iteration ready to be used.

Activities scheduled with deadlines

At least two iterations are needed to complete the TLO-Development activity with deadlines December 2012 and January 2013, respectively. Each iteration is planned to be monitored by opening related tickets. And, as in January there is going to be the next meeting, we (Claudio, Julien and Carlo) will discuss if we need a third or more iterations.

Meeting In Progress

=== Details of the meeting in Rome on 03.11.2012 can be found http://wiki.i-marine.eu/index.php/03.11.2012.MeetingInRome

First meeting on "FLOD Ontological Analysis: First Iteration", 7.12.2012

Motivation - Goal - Requirements

Describe a scenario that will justify the need for having such a TLO on top of marine-domain knowledge bases.

THE MOTIVATIONS ARE BASED ON THE FACT THAT: Semantic technologies, applications and services for biodiversity mostly rely on the rise of an interconnected and shared tree-of-life like dataset scaling on the web. The various communities (including also marine one) are contributing to this joint effort aim to share domain data and their meaning, to provide a solid basis for biodiversity systems interoperability.

THE GOAL IS: Our goal in modelling and formalising a Top Level Ontology (TLO) is for integrating and semantically extending the underlying models of existing marine data sources. Specifically, the TLO is used on the top of a number of real and heterogeneous marine data sources, including FLOD and ECOSCOPE, as knowledge mediator to represent, manipulate and reason upon and across them.

THE REQUIREMENTS ARE: This Top Level Ontology has to focus on EAF ( Ecosystem Approach to Fisheries / Marine Resources) and should be generic enough to provide consistent abstractions or specifications of concepts included in all data models or ontologies of iMarine data sources such as ECOSCOPE, TDWG-WORMS, FLOD, AGROVOC, DwC, IBIS [Gangemi 2002], [Doerr 2003], and provide the necessary properties to make this distributed knowledge base a coherent source of facts relating observational data with the respective spatiotemporal context and categorical (systematic) domain knowledge

FLOD Ontological Analysis

The ontological analysis of FLOD (+ references to documents/ wiki pages/ tickets). This activity is associated to the ticket https://issue.imarine.research-infrastructures.eu/ticket/888

This sub-activity, with the first iteration, has the primary goal to provide a common understanding of the FLOD ontology network. It has been considered necessary for the development of the TLO.

The first draft (04-Dec-2012) describing the FLOD Ontological Analysis at the first iteration can be found here http://bscw.research-infrastructures.eu/bscw/bscw.cgi/d260861/FLOD%20analysis%20First%20Iteration.pdf

The first (07-Dec-2012) Tconf on the FLOD Ontological Analysis at the first iteration can be found here http://wiki.i-marine.eu/index.php/7.12.2012-TLO_FLOD_Ontological_Analysis

Ecoscope Ontological Analysis

The ontological analysis of Ecoscope (+ references to documents/ wiki pages/ tickets). This activity is associated to the ticket https://issue.imarine.research-infrastructures.eu/ticket/889

This sub-activity, with the first iteration, has the primary goal to provide a common understanding of the ECOSCOPE ontology network. It has been considered necessary for the development of the TLO.

TLO Design

The activities carried out towards the design of TLO (+ references to documents / wiki pages/ tickets). This activity is associated to the ticket https://issue.imarine.research-infrastructures.eu/ticket/890

Here we describe the methodology of designing the TLO.

TLO Implementation

The activities carried out for the implementation of TLO (+ references to documents/ wiki pages/ tickets). This activity is associated to the ticket https://issue.imarine.research-infrastructures.eu/ticket/891

TLO Results

TLO Usage

Activities related to the usage of TLO (+ references to documents/ wiki pages/ tickets). This activity is associated to the ticket https://issue.imarine.research-infrastructures.eu/ticket/900

Here, we describe possible scenarios in which TLO can be evaluated. Currently, we identify the followings:

  • TLO as meta-model for FLOD and ECOSCOPE
  • TLO as knowledge model for semantic search in X-search
  • TLO as testing model for Gerald (?, not sure yet)

TLO Evaluation

Activities related to the evaluation of TLO (+ references to documents/ wiki pages/ tickets). This activity is associated to the ticket https://issue.imarine.research-infrastructures.eu/ticket/892

Here, we report the results of the evaluation of the TLO which are related to the specific used scenario.
