Antecedent implication
The modifier Antecedent means that the search is performed only to those property-values set as Constraints on the antecedent side and using the entire dataset as target for the consequent side.
We have a dedicated page for this: Universal Implication!
If you want to search for all possible relationships of a specific property-value with others property-value the Antecedent Implication search might be the right search to do, and it let you select which constraint you want to investigate on.
Whichever language has no Subject Verb ( No value) word order what other property-values have?
Select the Implication Antecedent in the Advanced Panel
CONSTRAINTS:
- Subject Verb Property, only No values.
Think to a dataset like the following:
| Property Name | Faroese | Fijian | French | Finnish |
|---|---|---|---|---|
| Subject Verb | Yes | No | No | Yes |
| Adjective Degree | No | Yes | Yes | - |
| Verb Object | No | Yes | Yes | - |
In the dataset above the engine will look for the combination
Subject Verb : No ==> Any Other Property : Any Value
The other Properties found are:
- Adjective Degree : Yes
- Verb Object : Yes The resulting languages are in both cases Fijian and French.
But, in general, you might want to ask something like:
Of course the Antecedent Implication search can do this. Go to the Search Page, select the Subject Verb and Verb Object as Constraint Properties for the search.
Select the Implication Antecedent in the Advanced Panel
CONSTRAINTS:
- Subject Verb Property, all values.
- Verb Object Property, all values.
and for the following dataset:
| Property Name | Faroese | Fijian | French | Finnish |
|---|---|---|---|---|
| Subject Verb | Yes | No | No | Yes |
| Adjective Degree | No | Yes | Yes | - |
| Verb Object | No | Yes | Yes | - |
The engine will look for the combination
Subject Verb: Any Value ==> Any Other Property : Any Value
Verb Object : Any Value ==> Any Other Property : Any Value
And the result it's the following:
| **Property Antecedent** : Value | Property Consequent : Value | Number of Languages | Languages |
|---|---|---|---|
| Subject Verb : No | Verb Object : Yes | 2 | French, Fijian |
| Subject Verb : No | Adjective Degree : Yes | 2 | French, Fijian |
| Verb Object : Yes | Subject Verb : No | 2 | French, Fijian |
| Verb Object : Yes | Adjective Degree : Yes | 2 | French, Fijian |
| Verb Object : No | Subject Verb : Yes | 1 | Faroese |
| Verb Object : No | Adjective Degree : No | 1 | Faroese |
So, the Adjective Degree property is completely ignored in antecedent* column, performing the Antecedent search with two others properties as Constraints.
Of course you can!
Now we add to the Contraints select above the Languages Fijian, French and Finnish.
CONSTRAINTS:
- Subject Verb Property, all values.
- Verb Object Property, all values.
- Only Languages: Fijian, French, Finnish.
The result will be the following:
| **Property Antecedent** : Value | Property Consequent : Value | Number of Languages | Languages |
|---|---|---|---|
| Subject Verb : No | Verb Object : Yes | 2 | French, Fijian |
| Subject Verb : No | Adjective Degree : Yes | 2 | French, Fijian |
| Verb Object : Yes | Subject Verb : No | 2 | French, Fijian |
| Verb Object : Yes | Adjective Degree : Yes | 2 | French, Fijian |
As you noticed, the result is quite similar to the one above without Language contraints, but there are no more the last two rows with the Faroese language.
If you don't select any Property / Language / Property-Value the action performed by the search engine is to search without any constraint. Each Constraint box is independent from the next one: selecting only Property constraints, the engine will perform the search through all values for those Properties in all available Languages in the dataset.
Antecedent Implication search without any constraint will return the same result as the Both Implication
There are limits on the size of searchable entries: in case your search will overpass the number of allowed by the search engine - usually on very huge datasets/groups - you will be redirected again to the Search Page with a notification on top page asking to add some constraint to the search.
