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 | Soil 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 |
| Crop | Crop Field | The kind of field the crop is being planted in, i.e. what was formerly planted in the field |
| 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 |
| doImmediately | step | step | Still a simple order but with a specific amount of time in between |
| doAtNight | step | step | Still a simple order but with a specific amount of time in between |
| doConcurrently | step | step, condition | When two processes happen at the same time, or when the step happens throughout the period of a particular condition |
| 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 method | step | Way to group the steps for a particular variety's normal method or special method |
| hasVariety | crop method | crop variety | Way to group the steps for a particular variety's normal method or special method |
| hasField | crop method | crop field | Way to group the steps for a particular variety's normal method or special method |
Explanation
- Length of time between steps --> denote via the relation itself
- Cannot use "or" relations
- For barley/wheat, it says "plow in the 5th or 6th months"
- But if we make two relations plow---5th month and plow---6th month and put an "or" relations between 5th month---or---6th month, then for all other crops that use the 5th or 6th month, there will be an "or" relation, but this "or" relation is only for barley/wheat, therefore, we cannot use "or" in this way
- It is not universally true for all crops
- Therefore, I used "doAfter" the 4th month, and "doBefore" the 7th month, to denote any time in the 5th or 6th months
