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(a: float = 0.95) -> OETverskySim

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

OETverskySim(a: float, b: float) -> OETverskySim

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

operator()

__call__(fpA: OEFingerPrint, fpB: OEFingerPrint) -> float

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

CreateCopy

CreateCopy() -> OETverskySim

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

GetAlpha() -> float

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

GetBeta

GetBeta() -> float

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

GetSimTypeString

GetSimTypeString() -> str

Returns a string representation of the OETverskySim class.
