Natural Language Processing
Turn an analysis into a surface word
BOTIE
Examples, experiments and workspace controls
Connect a tool's inputs to see what it produces. You can try a branch before connecting it to Result.
Try your own inputs
Use a copy of the example to try your own data. Keep the problem's assumptions in mind, and predict the effect of a change before checking the output. You can also add another branch to compare two ways of doing the calculation.
Context for this challenge
For these consonant-plus-y stems, apply the plural ending rule before vocabulary lookup. Build one rule that handles each stem.
Botie knows a singular stem and needs its plural spelling. These supplied stems end in consonant plus y, so the ending rule must be applied before vocabulary lookup.
Replace the final y with ies for the supplied stems, separate the resulting word, and use the surface vocabulary.
Examples and results
- Singular stem
city
- Surface-word IDs
{ "cities": 1, "citys": 2 }- Required result
- 01
Try a fresh construction
This clears this draft, including its undo history. Earlier successful attempts stay recorded. Build again without opening hints to record an independent attempt.
Stuck? Inspect a worked construction
The tools below form one possible solution. You can assemble it, follow its signals, and undo that change to return to your own construction.
Assumptions and test precision
This is a small construction problem. The lesson explains the assumptions and the parts of the full method that this example leaves out. Numerical tests allow a difference of 0.001. Lists and structures must also have the right shape.
Another consonant-y stem follows the spelling rule
This check uses the pieces from “Generate the plural surface form before assigning its ID”.
BOTIE
- Singular stem
berry
- Surface-word IDs
{ "berries": 14, "berrys": 15 }
Use a number, text, or an array matching the requested result. For a matrix, put each row in brackets. Saving your prediction runs your current construction on these inputs and checks the earlier examples too.
Build a construction in the workspace above first. This case will test those pieces.
Why does the vocabulary include tempting spellings such as partys alongside the desired form?
Surface generation and lookup are separate operations; a vocabulary entry existing does not make a generated form correct.
