OETverskySim

class OETverskySim : public OEGraphSim::OESimFuncBase

This class represents OETverskySim that calculates the Tversky similarity score.

Formula:

\(Sim_{Tversky}(A,B) = \frac{bothAB}{\alpha * onlyA + \beta * onlyB + bothAB}\)

Constructors

OETverskySim(float a=0.95f)

Default constructor (\(\alpha = 0.95\), \(\beta = 1.0 - \alpha = 0.05\))

OETverskySim(float a, float b)

Constructor with arbitrary \(\alpha\) and \(\beta\) parameters.

operator()

float operator()(const OEGraphSim::OEFingerPrint &fpA,
                 const OEGraphSim::OEFingerPrint &fpB) const

Returns the Tversky similarity coefficient of the two given OEFingerPrint objects.

CreateCopy

OEGraphSim::OESimFuncBase *CreateCopy() const

Deep copy constructor that returns a copy of the object. The memory for the returned OETverskySim object is dynamically allocated and owned by the caller.

GetAlpha

float GetAlpha() const

Returns the \(\alpha\) parameter of the Tversky similarity calculation.

GetBeta

float GetBeta() const

Returns the \(\beta\) parameter of the Tversky similarity calculation.

GetSimTypeString

std::string GetSimTypeString() const

Returns a string representation of the OETverskySim class.
