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.
