compare to Huet, verbs, periphrastic future tense

[funderburkjim]

This issue summarizes differences and similarities noticed in the comparison of verb conjugations; the methodology is described in the readme for huetcompare/verbs-tp-pef.

root comparison

huet_stems_pef.txt summarizes the roots that appear in periphrastic future conjugation forms in the SL_roots.xml file from Huet. For a given root, periphrastic future conjugations may appear in either the Parasamaipada or Atmanepada form (or both), and this pada information is also present in the stem file. Note: It is in fact the case that only Parasmaipada occurs.

pysan_stems_pef.txt summarizes the roots and padas that appear in the dcpforms-MW-verb.txt of the pysan system.

The two lists of roots and padas are compared in compare_stems_pef.txt.

This comparison is organized into categories:

• 232 cases of roots which appear in both sources, and with the same pada data
• 212 cases of roots that appear in both sources, but with Huet showing only parasmaipada and pysan showing both padas
• 86 cases of roots that appear in both sources, but with Huet showing both parasmaipada and pysan showing atmanepada
• 1084 cases of roots which appear only in the pysan source
• 202 cases of roots which appear only in the Huet source (Many of these roots are identified, in their present tense conjugations, as denominatives.)

conjugation table comparison

huet_conj_tables_pef.txt contains 732 periphrastic future tense conjugation tables derived from Huet's SL_roots.xml.

Each of these appears on one line of the file.

For each of these Huet computations, a comparable computation from the pysan system was prepared, taking into account the class-pada information used by pysan periphrastic future tense computations. The result is pysan_conj_tables_pef.txt.

compare_conj_tables_pef.txt summarizes the similarities and differences in the corresponding conjugations from the two files just mentioned. Some statistics resulting from the comparison:

• 391 (53% of the 732) periphrastic future conjugations are identical in the two systems.
• 202 (28%) of the Huet conjugations have no comparable pysan conjugation.
  • This is largely due to the presence of denominatives in Huet, which are not included in the Pysan work.
• 139 (19%) of the remaining conjugations differ in one or more details.
  • Some of these differences may be attributed to differences in the i-insert (with-i, without-i, with-and-without-i) in the two systems.

This ends the preliminary observations comparing the two systems for the periphrastic future.
