focus

usage: common - datatype: object


The focus for a Tag.script is the intersection of the background attribute and the set of entities defined by the focus attribute. The focus attribute is mandatory when the analysis method is "tag-comparison". There is no default value for the focus attribute, therefore an error will be thrown if it is undefined for a "tag-comparison" analysis. The simple form of the focus attribute is a single categorical variable object.

"focus": {
  "variable_type": "categorical", //A categorical variable object
  "collection": "cccc", //"cccc" is a valid categorical collection name in tag.cortex
  "variable": "vvvv" //"vvvv" is a valid variable name in collection "cccc"
}

Alternatively, the focus attribute can be any categorical variable object that compiles to a single categorical variable, e.g. "categorical-compound".

"focus": {
  "variable_type": "categorical-compound",
  "operator": "oooo", //"AND" for intersection, "OR" for union
  "criteria": [
    {...}, //Two or more categorical variable objects
    {...},
    ...   
  ]
}
