freq

public static int freq(IndexSearcher searcher,
                       String corpusToSearchIn,
                       String annotationSetToSearchIn,
                       String annotationType,
                       String featureName,
                       String value)
                throws SearchException

Allows retriving frequencies for the given parameters. Please make sure that you close the searcher on your own. Failing to do so may result into many files being opened at the same time and that can cause the problem with your OS.

Throws:

SearchException

freq

public static int freq(List<Hit> patternsToSearchIn,
                       String annotationType,
                       String feature,
                       String value,
                       boolean inMatchedSpan,
                       boolean inContext)
                throws SearchException

Allows retrieving frequencies for the given parameters.

Parameters:

value - - set to null if only wants to retrieve frequencies for AT.feature

inMatchedSpan - - true if only interested in frequencies from the matched spans.

inContext - - true if only interested in frequencies from the contexts. Please note that both isMatchedSpan and inContext can be set to true if interested in frequencies from the entire patterns, but cannot be set false at the same time.

Throws:

SearchException

                                            throws SearchException

Calculates frequencies for all possible values of the provided AT.feature

Parameters:

patternsToSearchIn -

annotationType -

feature -

inMatchedSpan -

inContext -

Returns:

returns a map where key is the unique value of AT.feature and value is the Integer object giving count for the value.

Throws:

SearchException
