Constructor Detail

TopicCoverage

public TopicCoverage(TopicFrequency[] array,
                     boolean sort)

Constructor

Parameters:

array - the array of TopicFrquency objects to be stored in this TopicCoverage

sort - if true causes the TopicFrequencies to be sorted

TopicCoverage

public TopicCoverage(TopicFrequency[] array)

Constructor

Parameters:

array - the array of TopicFrequency objects to be stored in this TopicCoverage

TopicCoverage

public TopicCoverage(java.util.Vector V)

Constructor

Parameters:

V - the Vector of topic frequencies to be stored in this TopicCoverage

Method Detail

coverageMean

public double coverageMean()

Returns:

the mean value for the coverage frequency of topics contained in this object

coverageVariance

public double coverageVariance()

Returns:

the variance value for the coverage frequency of topics contained in this object

getLowCoveredConcepts

public java.lang.String[] getLowCoveredConcepts()

Returns:

the 10% low covered topics, i.e., the 10% topics having less resources pointing to them by means of semantic annotations

getLowCoveredConceptsM

public java.lang.String[] getLowCoveredConceptsM()

Returns:

the topics having the coverage value under a given fraction of the coverage mean computed as:
coverage < mean - sqrt(variance)
