Remove unclassified values - Fluid Topics - Latest

In all documents about gazelles, the following values are set for the keyword metadata key:

Document	keyword value 1	keyword value 2
Gazelle Definition	mammal	Africa
Gazelle Etymology and Name	mammalia	Middle-East
Gazelle Species	Africa	viviparous animal
Gazelle Prehistoric Extinctions	viviparous	africa

The keywords related to the type of animal are useful, but those referring to a geographical location are not.

If documents are published as is, the keyword facet values are displayed in Fluid Topics as follows:

ADMIN and KHUB_ADMIN users can clean facet values so that only the most useful ones appear as follows:

1. In the Vocabularies administration interface, create a new vocabulary named keyword_clean to apply the following synonyms:

   • Mammal=(mammal, mammalia, viviparous, viviparous animal)

2. In the Enrich and Clean administration interface, configure a new rule.

3. Select the Remove unclassified values option.

4. Set the keyword metadata element so that it appears on the portal. See Declare metadata.

Since the Africa, africa, and Middle-East values are not mentioned in the keyword_clean vocabulary, Fluid Topics ignores them when creating the facet.

The following screenshot shows the result of cleaning the keyword metadata value in Fluid Topics:
