Member Function Documentation

double WordPairComparison::comparePair (  const Word &  w1, const Word &  w2 )  const

Compare the pair of words using similarity measure. Parameters: w1  - the first word w2  - the second word. Returns: the distance (value of the similarity measure)

double WordPairComparison::comparePair (  const Word &  w1, const Word &  w2, const vector< double > &  measureDistr )  const

Compare the pair of words using probabilistic measure. Parameters: w1  - the first word w2  - the second word. measureDistr  - distribution of the distance between two random words Returns: an estimate of the probability of words w1 and w2 been generated independently

vector<double> WordPairComparison::distrEstimate (  int  minLen, int  maxLen, int  nSamples = 1000 )  const

Estimates the distribution of the distances (similarities) between two randomly generated words. Parameters: minLen  - the minimal length of a randomly generated word maxLen  - the maximal length of a randomly generated word nSamples  - the number of pair samples to be generated (1000 is the default value). Returns: vector of the sorted distances (similarity measures)
