38 The methods available to create fingerprints bit vector from strings and
|
|
|
39 to calculate similarity coefficient between two bit vectors can also be
|
|
|
40 invoked as class functions.
|
|
|
41
|
|
|
42 FingerprintsBitVector class is derived from BitVector class which
|
|
|
43 provides the functionality to manipulate bits.
|
|
|
44
|
|
|
45 For two fingerprints bit vectors A and B of same size, let:
|
|
|
46
|
|
|
47 Na = Number of bits set to "1" in A
|
|
|
48 Nb = Number of bits set to "1" in B
|
|
|
49 Nc = Number of bits set to "1" in both A and B
|
|
|
50 Nd = Number of bits set to "0" in both A and B
|
|
|
51
|
|
|
52 Nt = Number of bits set to "1" or "0" in A or B (Size of A or B)
|
|
|
53 Nt = Na + Nb - Nc + Nd
|
|
|
54
|
|
|
55 Na - Nc = Number of bits set to "1" in A but not in B
|
|
|
56 Nb - Nc = Number of bits set to "1" in B but not in A
|
|
|
57
|
|
|
58 Then, various similarity coefficients [ Ref. 40 - 42 ] for a pair of bit
|
|
|
59 vectors A and B are defined as follows:
|
|
|
60
|
|
|
61 BaroniUrbani: ( SQRT( Nc * Nd ) + Nc ) / ( SQRT ( Nc * Nd ) + Nc + ( Na
|
|

|
|
|

|
|
|

|
|
|
84
|
|
|
85 Kulczynski2: ( ( Nc / 2 ) * ( 2 * Nc + ( Na - Nc ) + ( Nb - Nc) ) ) / (
|
|
|
86 ( Nc + ( Na - Nc ) ) * ( Nc + ( Nb - Nc ) ) ) = 0.5 * ( Nc / Na + Nc /
|
|
|
87 Nb )
|
|
|
88
|
|
|
89 Matching: ( Nc + Nd ) / Nt
|
|
|
90
|
|
|
91 McConnaughey: ( Nc ** 2 - ( Na - Nc ) * ( Nb - Nc) ) / ( Na * Nb )
|
|
|
92
|
|
|
93 Ochiai: Nc / SQRT ( Na * Nb ) (same as Cosine)

95 Pearson: ( ( Nc * Nd ) - ( ( Na - Nc ) * ( Nb - Nc ) ) / SQRT ( Na * Nb
|
|
|

|
|
|
97
|
|
|
98 RogersTanimoto: ( Nc + Nd ) / ( ( Na - Nc) + ( Nb - Nc) + Nt) = ( Nc +
|
|
|
99 Nd ) / ( Na + Nb - 2Nc + Nt)

|
|
|
104
|

105 SkoalSneath1: Nc / ( Nc + 2 * ( Na - Nc) + 2 * ( Nb - Nc) ) = Nc / ( 2 *
|
|
|
106 Na + 2 * Nb - 3 * Nc )
|
|
|
107
|
|
|
108 SkoalSneath2: ( 2 * Nc + 2 * Nd ) / ( Nc + Nd + Nt )
|
|
|
109
|
|
|
110 SkoalSneath3: ( Nc + Nd ) / ( ( Na - Nc ) + ( Nb - Nc ) ) = ( Nc + Nd )
|
|
|
111 / ( Na + Nb - 2 * Nc )

|
|
112
|
|
|
113 Tanimoto: Nc / ( ( Na - Nc) + ( Nb - Nc ) + Nc ) = Nc / ( Na + Nb - Nc )
|
|
|
114 (same as Jaccard)
|
|
|
115
|
|
|
116 Tversky: Nc / ( alpha * ( Na - Nc ) + ( 1 - alpha) * ( Nb - Nc) + Nc ) =
|
|

|
|
119 Yule: ( ( Nc * Nd ) - ( ( Na - Nc ) * ( Nb - Nc ) ) ) / ( ( Nc * Nd ) +
|
|
|
120 ( ( Na - Nc ) * ( Nb - Nc ) ) )
|
|
|
121
|
|
|
122 The values of Tanimoto/Jaccard and Tversky coefficients are dependent on
|
|
|
123 only those bit which are set to "1" in both A and B. In order to take
|
|
|
124 into account all bit positions, modified versions of Tanimoto [ Ref. 42
|
|
|
125 ] and Tversky [ Ref. 43 ] have been developed.
|
|
|
126
|
|
|
127 Let:
|
|
|
128
|
|
|
129 Na' = Number of bits set to "0" in A
|
|
|
130 Nb' = Number of bits set to "0" in B
|
|
|
131 Nc' = Number of bits set to "0" in both A and B
|
|
|
132
|
|
|
133 Tanimoto': Nc' / ( ( Na' - Nc') + ( Nb' - Nc' ) + Nc' ) = Nc' / ( Na' +
|
|
|
134 Nb' - Nc' )
|
|
|
135
|
|
|
136 Tversky': Nc' / ( alpha * ( Na' - Nc' ) + ( 1 - alpha) * ( Nb' - Nc' ) +
|
|
|
137 Nc' ) = Nc' / ( alpha * ( Na' - Nb' ) + Nb')
|
|
|
138
|
|
|
139 Then:
|
|
|
140
|
|
|
141 WeightedTanimoto = beta * Tanimoto + (1 - beta) * Tanimoto'
|
|
|
142
|
|
|
143 WeightedTversky = beta * Tversky + (1 - beta) * Tversky'
