FreqTable

public FreqTable(com.sleepycat.je.Environment env,
         java.lang.String fn,
         boolean write)
          throws com.sleepycat.je.DatabaseNotFoundException

Throws:

com.sleepycat.je.DatabaseNotFoundException

Method Detail

getFrequency

public int getFrequency(java.lang.String sik)

put

public int put(java.lang.String sik,
      int noccur)

remove

public int remove(java.lang.String sik,
         int noccur)

getTotalNoOfTokens

public int getTotalNoOfTokens()

getTotalNoOfTypes

public int getTotalNoOfTypes()

Retrive total number of types, where each (case-sensitive) form of a word counts as a type. Possibly not what you are after. See modnlp.idx.database.CaseTable#getTotalNoOfTokens for an alternative that corresponds to the usual definition of number of types.

Returns:

an int value

getTypeTokenRatio

public double getTypeTokenRatio()

Return the case-sensitive type token ratio. That's probably not a very useful metric. See Dictionary.getTypeTokenRatio(boolean) for a better alternative.

Returns:

a double value
