Usage¶

Command line usage¶

The sanskrit_parser script can be used to view parses, sandhi splits, or morphological tags as below.

If the --dot option is provided, a graph is output in .dot fomat with all the possible morphologies as nodes, and possible relations as edges. The valid parses extracted from this graph are also written out as _parse.dot files

It provides three main levels of output, in order of increasing complexity:

tags - Morphological analysis of a word
sandhi - Sandhi Split of a phrase
vakya - Morpho-syntactic Analysis of a sentence (after Sandhi split)

Vakya Analysis¶

$ sanskrit_parser vakya devadattogrAmaNgacCati --input SLP1 --dot vakya.dot
...
Parse 0 : (Cost = 2.205)
devadattaH => (devadatta, ['ekavacanam', 'puMlliNgam', 'praTamAviBaktiH']) : kartA of gacCati
grAmam => (grAma, ['ekavacanam', 'dvitIyAviBaktiH', 'napuMsakaliNgam']) : karma of gacCati
gacCati => (gam, ['kartari', 'law', 'prATamikaH', 'ekavacanam', 'praTamapuruzaH', 'parasmEpadam'])
Parse 1 : (Cost = 2.205)
devadattaH => (devadatta, ['ekavacanam', 'puMlliNgam', 'praTamAviBaktiH']) : kartA of gacCati
grAmam => (grAma, ['ekavacanam', 'dvitIyAviBaktiH', 'puMlliNgam']) : karma of gacCati
gacCati => (gam, ['kartari', 'law', 'prATamikaH', 'ekavacanam', 'praTamapuruzaH', 'parasmEpadam'])
...

To view the generated dot files, convert them into png first.

Sandhi Split¶

$ sanskrit_parser sandhi astyuttarasyAMdishidevatAtmA
...
Splits:
[asti, uttarasyAm, diSi, devatA, AtmA]
[asti, uttara, syAm, diSi, devatA, AtmA]
[astI, uttarasyAm, diSi, devatA, AtmA]
[asti, uttarasyAm, diSi, devatAt, mA]
[asti, uttarasyAm, diSi, devata, AtmA]
[asti, uttarasyAm, diSi, devat, AtmA]
[asti, uttarasyAm, diSi, devatAtmA]
[asti, uttarasyAm, diSi, devatA, at, mA]
[asti, uttara, syAm, diSi, devat, AtmA]
[asti, uttarasyAm, di, Si, devatA, AtmA]

Morphological Tags for a Word¶

$ scripts/sanskrit_parser tags hares
...
Morphological tags:
('hf#1', {ekavacanam, viDiliN, prATamikaH, kartari, maDyamapuruzaH})
('hari#1', {ekavacanam, puMlliNgam, paYcamIviBaktiH})
('hari#1', {ekavacanam, paYcamIviBaktiH, strIliNgam})
('hari#1', {zazWIviBaktiH, ekavacanam, puMlliNgam})
('hari#1', {zazWIviBaktiH, ekavacanam, strIliNgam})
('hari#2', {ekavacanam, puMlliNgam, paYcamIviBaktiH})
('hari#2', {ekavacanam, paYcamIviBaktiH, strIliNgam})
('hari#2', {zazWIviBaktiH, ekavacanam, puMlliNgam})
('hari#2', {zazWIviBaktiH, ekavacanam, strIliNgam})
('hf', {ekavacanam, parasmEpadam, viDiliN, maDyamapuruzaH})
('hari', {ekavacanam, puMlliNgam, paYcamIviBaktiH})
('hari', {ekavacanam, strIliNgam, paYcamIviBaktiH})
('hari', {zazWIviBaktiH, ekavacanam, puMlliNgam})
('hari', {zazWIviBaktiH, ekavacanam, strIliNgam})
