CONTEXTCOUNT
A Paragraph is annotated with a KeywordParagraph annotation, if it contains between two and four
Keyword annotations.
Paragraph{CONTAINS(Keyword,50,100,true)->MARK(KeywordParagraph)};
A Paragraph is annotated with a KeywordParagraph annotation, if it contains between 50%
and 100% Keyword annotations. This is calculated based on the tokens of the Paragraph.
If the Paragraph contains six basic annotations (see Section 2.2, “Basic annotations and
tokens” [20]), two of them are part of one Keyword annotation, and if one basic annotation is
also annotated with a Keyword annotation, then the percentage of the contained Keywords is 50%.
2.6.5. CONTEXTCOUNT
The CONTEXTCOUNT condition numbers all occurrences of the matched type within the
context of a passed type's annotation consecutively, thus assigning an index to each occurrence.
Additionally it stores the index of the matched annotation in a numerical variable if one is passed.
The condition evaluates true if the index of the matched annotation is within a passed interval. If no
interval is passed, the condition always evaluates true.
2.6.5.1. Definition:
CONTEXTCOUNT(Type(,NumberExpression,NumberExpression)?(,Variable)?)
2.6.5.2. Example:
Keyword{CONTEXTCOUNT(Paragraph,2,3,var)
->MARK(SecondOrThirdKeywordInParagraph)};
Here, the position of the matched Keyword annotation within a Paragraph annotation is calculated
and stored in the variable 'var'. If the counted value lies within the interval [2,3], then the matched
Keyword is annotated with the SecondOrThirdKeywordInParagraph annotation.
2.6.6. COUNT
The COUNT condition can be used in two different ways. In the first case (see first definition),
it counts the number of annotations of the passed type within the window of the matched
annotation and stores the amount in a numerical variable, if such a variable is passed. The condition
evaluates true if the counted amount is within a specified interval. If no interval is passed, the
condition always evaluates true. In the second case (see second definition), it counts the number
of occurrences of the passed VariableExpression (second parameter) within the passed list (first
parameter) and stores the amount in a numerical variable, if such a variable is passed. Again, the
condition evaluates true if the counted amount is within a specified interval. If no interval is passed,
the condition always evaluates true.
2.6.6.1. Definition:
COUNT(Type(,NumberExpression,NumberExpression)?(,NumberVariable)?)
COUNT(ListExpression,VariableExpression
(,NumberExpression,NumberExpression)?(,NumberVariable)?)
