Objective ObjectEditor Irrigation Ontology Conclusions Future Work

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

Irrigation Ontology

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.

PDF

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
