SynsetVector2SynsetFeatureVectorPipe$new(propertyName = "",
                                         alwaysBeforeDeps = list(),
                                         notAfterDeps = list())

`propertyName`	(character) Name of the property associated with the pipe.
`alwaysBeforeDeps`	(list) The dependences alwaysBefore (pipes that must be executed before this one).
`notAfterDeps`	(list) The dependences notAfter (pipes that cannot be executed after this one).

An object of class R6ClassGenerator of length 24.

The groupStrategy is one of the following: - COUNT: indicates the number of times that a synset is observed in the content. - BOOLEAN: Indicates if the synset is observed in the content (1) or not (0). - FREQUENCY: Indicates the frequency of the synset in the text that is the count of times that the synset is observed divided by the whole amount of synsets.

This class inherits from PipeGeneric and implements the pipe abstract function.

pipe Function that preprocesses the instance to remove html tags.
- Usage
  
  pipe(instance, groupStrategy = "COUNT")
- Value
  
  The instance with the modifications that have occurred in the pipe.
- Arguments
  - instance (Instance) Instance to preproccess.
  - groupStrategy (character) Strategy to count the synstes. It can be COUNT, BOOLEAN or FREQUENCY.
