ProjectProgramme / project report7.3.1: Results from experiments in ontology learning including evaluation and recommendation
NeOn: Lifecycle Support for Networked Ontologies, Integrated Project (IST-2005-027595). Priority: IST-2004-2.4.7,
2007Also available in:
No results found.This document describes the Ontology Learning experiments we performed in order to recommend a set of ontology learning techniques to enhance the ontology engineering process in the fisheries domain in place at FAO. Experiments have been conceived in the wider context of the WorkPackage 7 of the NeOn Project. The main contribution of this document to WP7 is a set of recommendations and best practices to exploit semi-automatic technique to acquire knowledge either from domain specific documents a nd existing ontologies. The basic criterion for success indication adopted is the reduction of the development time required for the Ontology Engineering process actually in place at FAO. After a brief overview of WP7, the document addresses the following issues: to describe the state of the art in ontology learning and; to set up an evaluation case study in the fisheries domain; to identify suitable techniques which can be profitably applied to fit the user’s requirements; to evaluate such tech niques in the use case scenario, and, finally, to provide a set of recommendations indicating the most reliable techniques to be included in the ontology engineering lifecycle. -
ProjectProgramme / project reportD7.1.2 Revised specifications of user requirements for the Fisheries, case study
NeOn: Lifecycle Support for Networked Ontologies, Integrated Project (IST-2005-027595). Priority: IST-2004-2.4.7,
2008Also available in:
No results found.This document revises and updates the user requirements for the Fisheries case study (WP7) originally prepared in D7.1.1 (in M7). As highlighted in the introduction (Chapter 1), the purpose of this deliverable, 22 months after the launch of the NeOn project, is to refine the user requirements for the WP7 case study. This refinement of the user requirements is also meant to enhance the alignment of the case study with the NeOn project and better contribute to it as a whole. The user r equirements for the Fisheries ontologies lifecycle management system are presented in Chapter 2. This chapter also includes an updated description of user’s roles and requirements for ontology engineers and ontology editors. The requirements for the FSDAS are revisited in Chapter 3. That chapter covers the general characteristics of the FSDAS (i.e., its scope, perspective, features), the refinement and extension of the functional requirements, its foreseen user types, and a number of u ser interface issues and non-functional requirements. Conclusions are presented in Chapter 4. This deliverable also includes five annexes with additional detailed information. Annex A provides a summary of the requirements presented in Chapter 2, together with their mapping to the NeOn architecture. Annex B traces all changes to requirements, scenarios and uses cases from D7.1.1 until now. Annex C consists of tables that are meant to help the reader trace the changes (modifications /refinements) with respect to the requirements presented in D7.1.1 and D7.5.1. Finally, Annex D and Annex E list the revised use cases and the new use cases for FSDAS respectively. -
ProjectProgramme / project reportD7.4.1 Software architecture for managing the Fisheries ontologies lifecycle
NeOn: Lifecycle Support for Networked Ontologies, Integrated Project (IST-2005-027595). Priority: IST-2004-2.4.7,
2007Also available in:
No results found.This document describes the software architecture for implementing a system for managing the fisheries ontologies lifecycle, cornerstone of WP7. The lifecycle described in this deliverable is an instantiation of the possible lifecycles that can be carried out with the NeOn toolkit, and has been selected according to FAO needs, style of work and organizational culture. This document is also an extension and refinement of D7.1.1 in terms of requirements that should be fulfilled by the ge neral NeOn lifecycle management support. The architecture is based on the NeOn Toolkit and engineering components, and will be incrementally integrated into the system through subsequent T7.4 deliverables, i.e. deliverables D7.4.2 and D7.4.3. Since D7.1.1 the requirements about the Fisheries Ontologies Lifecycle have evolved been more concrete (as in any software development process). Chapter 1 of the document describes the major requirements of the Fisheries Ontologies Lifecycle Manag ement System. Chapter 2 provides an overview of the process required for building, populating, publishing and maintaining the fisheries ontologies. Chapter 3 includes use case diagrams and a brief description of each use case required for implementing the system. These use cases are based on the requirements described in early WP7 deliverable D7.1.1, and each use case provides references to the relevant sections in D7.1.1. A detailed description of each use case and the engineering c omponents to be integrated in the system are included in Annex I of this document. Chapter 4 presents the system architecture derived from the use cases, as a selection of components of the NeOn Toolkit and system architecture. Chapter 5 describes the plan for subsequent T7.4 deliverables. Finally, Chapter 6 highlights the major conclusions of deliverable D7.4.1.

Policy briefPolicy briefOutcomes and lessons learned from the Koronivia UNFCCC negotiations on agriculture and food security, and the way forward after COP 27
Brief note
2023Also available in:
No results found.The Koronivia Joint Work on Agriculture (KJWA) was established at COP23 to address six topics in the agricultural sector's role in climate change. KJWA has contributed to sharing scientific and technical knowledge, but limitations remain in translating outcomes into concrete climate actions. The new four-year joint work on the implementation of climate action on agriculture and food security, which prioritizes ending hunger and considers national circumstances, includes the creation of an online portal for sharing information. The four-year agenda is shaped and broadened through the submission of views by parties, observers, and civil society and will be considered by SBSTA and SBI in June 2023. -
Book (series)FlagshipThe State of Food Security and Nutrition in the World 2023
Urbanization, agrifood systems transformation and healthy diets across the rural–urban continuum
2023This report provides an update on global progress towards the targets of ending hunger (SDG Target 2.1) and all forms of malnutrition (SDG Target 2.2) and estimates on the number of people who are unable to afford a healthy diet. Since its 2017 edition, this report has repeatedly highlighted that the intensification and interaction of conflict, climate extremes and economic slowdowns and downturns, combined with highly unaffordable nutritious foods and growing inequality, are pushing us off track to meet the SDG 2 targets. However, other important megatrends must also be factored into the analysis to fully understand the challenges and opportunities for meeting the SDG 2 targets. One such megatrend, and the focus of this year’s report, is urbanization. New evidence shows that food purchases in some countries are no longer high only among urban households but also among rural households. Consumption of highly processed foods is also increasing in peri-urban and rural areas of some countries. These changes are affecting people’s food security and nutrition in ways that differ depending on where they live across the rural–urban continuum. This timely and relevant theme is aligned with the United Nations General Assembly-endorsed New Urban Agenda, and the report provides recommendations on the policies, investments and actions needed to address the challenges of agrifood systems transformation under urbanization and to enable opportunities for ensuring access to affordable healthy diets for everyone. -
Book (stand-alone)Technical bookFood loss analysis: causes and solutions – The Republic of Uganda. Beans, maize, and sunflower studies 2019
Also available in:
No results found.This report illustrates the food loss assessment studies undertaken along the maize, sunflower and beans supply chains in Uganda in 2015-16 and 2016-17. They aimed to identify the critical loss points in the selected supply chains, the key stages at which food losses occur, why they occur, the extent and impact of food losses and the economic, social and environmental implications of the food losses. Furthermore, these studies also evaluated the feasibility of potential interventions to reduce food losses and waste.
