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)
