For this final project, I explored how to organized the various processes and steps of Nongsa jikseol. This was challenging because the steps of one plant variety are dependent on the steps of other varieties, some varieties share some of the same processes but not others, some steps are conditional on certain events such as a particular date on the calendar or the growth of a plant to a certain height, etc.

Below, I have included my suggested ontology.Then I will explain the rationale behind this ontology.


Ontology

Classes

Type Class Description
Step Soil Preparation Field selection, plowing, tilling, etc.
Step Land Fertilization Fertilization of soil
Step Seed Preparation Preparing the seeds for planting, such as rinsing them in water, covering them with fertilizer, etc.
Step Sowing Putting the seeds into the soil and manipulating the soil so that the seeds can be covered, etc.
Step Weeding Removing weeds from the soil by means of hand, hoe, ox, etc.
Step Harvesting Cutting or picking the ripe crops
Time Static Time Timings based on the sun and moon (i.e. calendar time)
Time Dependent Time Timings based on the things which have flexible or unpredictable lengths or occurrences, such as "when the plant grows three inches" or "when the snow melts"
Condition Condition Conditions under a step is or is not performed that are not related to time
Crop Crop Variety A crop variety
Crop Crop Method Sometimes the same crop has an alternative method (such as relay cropping), which can be denoted with this crop method class
Tool Tool The tool(s) used to complete the step (not included in my examples)
Way Way The manner in which the step is completed (i.e. adjectives) (not included in my examples)

Relations

Relation Domain Range Description
then step step Simple ordering of steps
doAfterThreeDays step step Still a simple order but with a specific amount of time in between
doWhen step time Do the step when the time event occurs
doBefore step time Do the step before the time event occurs
doAfter step time Do the step after the time event occurs
idealTime step time When there are multiple possible timings, this timing is best
okayTime step time When there are multiple possible timings, this timing is acceptable
worstTime step time When there are multiple possible timings, this timingis worst
doIf step, crop condition Only do the step in this case
doNotDoIf step, crop condition Do not do the step in this case
hasStep crop step Way to group the steps for a particular variety's normal method or special method
