Overall Project Objectives
Production of Personalized Illustration-based Extension Manuals for Illiterate farmers in developing countries.
To develop culture specific (localized) educational materials.
ObjectEditor
ObjectEditor Is an ontology management system that
includes a formally defined ontology language which also acts as a data modeling language for the database
This is a web-based tool that consists on a graphic interface to create the concepts and relationships that are part of a domain specific ontology.
ObjectEditor
Provides: Tools for inspecting and editing the ontology
Operations for manipulating the ontology (reasoners)
Secondary storage management to support efficient processing of these operations

Domain Ontology
Ontology is a structure to describe a domain’s concepts as well as multiple relationships among those concepts.
An ontology formally describes a domain; it provides a generic way to reuse and share content across applications and groups.
Ontology Development Define the domain, objectives, and scope of the
ontology Enumerate important concepts within the
ontology’s domain Define concepts, and/or its properties Define the hierarchy of the concepts Define the relationships among the concepts
Irrigation Ontology Objectives
Create an irrigation ontology to support management and storage of information, and knowledge sharing for the development of educational resources for small farmers.
Irrigation Ontology Objectives
To develop an ontology that will collect and organize terminology and concepts related to the irrigation domain.
Allow information sharing and agreement on the terms used by experts in the field.
Irrigation Ontology Domain:
Irrigation concepts to develop educational materials for small farmers with low literacy level.
Define Main Topics: Discussion among experts
Hierarchy Mostly Top-down
Relationships
Sources of Information Land and Water Development Division of
the Food and Agricultural Organization (FAO)
American Society of Agricultural Engineering (ASAE)
United States National Agricultural Library Thesaurus (NALT)
Extension Data Information Source (EDIS) and Experts from the University of Florida

Content
Different formats can be stored in the irrigation ontology: Text Numeric (equations) Graphics Audiovisual
Conclusions
Conclusions Ontology can represent irrigation
knowledge and store concepts The ObjectEditor based ontology can store
information in multiple media like text, graphics, numerical, and mathematical equations.
The materials could be generated in different formats like PDF files for printing, or as html files for web pages.
Illustrations based materials
Conclusions
Allows more easy collaboration among specialist
Capability of reusing existing information
It would also allow the management of a larger amount of data
Improved searching capabilities compared to the actual browsers
Future Work
Future Work
Include Scalable Vector Graphics (SVG) illustrations in ObjectEditor Merge ObjectEditor with GraphicsEditor
Create an interface for the final users (e.g., extension agents, educators)
Increase searching capabilities
GraphicsEditor
Add SVG capabilities to ObjectEditor: Localization Reusability Format
independent
SVG illustrations
Localization: Inclusion of
culture specific characteristics
Increases understanding by users
