|
44
|
|
|
|
|
45
|
|
|
ALINE alignment was developed by |
|
46
|
|
|
:cite:`Kondrak:2000,Kondrak:2002,Downey:2008`, and establishes an |
|
47
|
|
|
alignment algorithm based on multivalued phonetic features and feature |
|
48
|
|
|
salience weights. Along with the alignment itself, the algorithm produces a |
|
49
|
|
|
term similarity score. |
|
50
|
|
|
|
|
51
|
|
|
:cite:`Downey:2008` develops ALINE's similarity score into a similarity |
|
52
|
|
|
measure & distance measure: |
|
53
|
|
|
|
|
54
|
|
|
.. math:: |
|
55
|
|
|
|
|
56
|
|
|
sim_{ALINE} = \frac{2 \dot score_{ALINE}(src, tar)} |
|
57
|
|
|
{score_{ALINE}(src, src) + score_{ALINE}(tar, tar)} |
|
58
|
|
|
|
|
59
|
|
|
However, because the average of the two self-similarity scores is not |
|
60
|
|
|
guaranteed to be greater than or equal to the similarity score between |
|
61
|
|
|
the two strings, by default, this formula is not used here in order to |
|
62
|
|
|
guarantee that the similarity measure is bounded to [0, 1]. Instead, |
|
63
|
|
|
Kondrak's similarity measure is employed: |
|
64
|
|
|
|
|
65
|
|
|
.. math:: |
|
66
|
|
|
|
|
67
|
|
|
sim_{ALINE} = \frac{score_{ALINE}(src, tar)} |
|
68
|
|
|
{max(score_{ALINE}(src, src), score_{ALINE}(tar, tar))} |
