Mapping between Currier A and B

[Torsten]

Assuming I have not made majors errors, one can see at least four different patterns:

1. the two ch-words that are most frequent in HerbalA (chol, chor) have smaller and smaller frequencies has you move towards B;
   
2. symmetrically, there are words that are rare in A and progressively more frequent in B (cheey, chckhy);
   
3. there are words that do not appear in A and are frequent in B (chedy, chdy); this asymmetry could be useful in choosing the direction of the mapping A->B or B->A;
   
4. chey is somehow constant across sections.
   

If you would build lists for common initial glyphs like <d->, <s->, <o->, or <qo-> you would get similar results. The same is true for typical word final glyphs like <-in>, <-l>, <-r>, or <-y>. 

The following table lists the five most frequent <-in>-words for different sections:
Herbal A      daiin    dain   chaiin     aiin    otaiin
Pharma A      daiin    aiin     dain   olaiin     saiin
Astro         daiin    aiin     dain   odaiin oteodaiin   
Cosmo          aiin   daiin  qokaiin   ytaiin    ykaiin
Herbal B       aiin   daiin   okaiin  qokaiin     saiin
Stars B        aiin   daiin  qokaiin   okaiin    otaiin
Biological B qokain qokaiin    daiin     dain     okain

The top words occur with the following frequencies:
               daiin  dain  aiin   odaiin  okaiin  otaiin  qokaiin qokain   word count
              ------ ----- ------ ------- ------- ------- -------- ------  -----------
Herbal     (A)   403    80     33      20      28      28       15      1        8,087
Pharma     (A)    99    13     30       4       6       3        2      1        2,529
Astro             12     4     11       3       1                                2,136
Cosmo             36     3     56       7       9      14       18      6        2,691
Herbal     (B)    72    11     72       4      31       8       20      5        3,233
Stars      (B)   122    53    193      17      94      74      114    105       10,673
Biological (B)    84    47     32       1      34      12       88    159        6,911

The two tables illustrate the usage of word pairs like <daiin/dain>, <daiin/aiin>, <daiin/odaiin>, <okaiin/otaiin> or <qokaiin/qokain>.

The reason for this observation is that "all pages containing at least some lines of text do have in common that pairs of frequently used words with high mutual similarity appear. The exact co-occurrences may vary: there are pages where <daiin> is paired with <dain>, but also pages where it is frequently used together with <aiin> (f41v, f46r, f55v, f89v2, v105v, and f114r) or <saiin> (f2r, f16r, and f90r2)" (You are not allowed to view links.

Or to say it with Renés words: "A given word pattern is just about as likely to start with <o-> as with <qo->, or with <ch-> vs. <sh->, or contain <k> vs. <t>, or <p> vs <f>, or end with <-y> vs. <-dy> or <-in> vs. <-iin>" (You are not allowed to view links.
