Apertium recursive

12.12.2023 first day

Hente nye par:

Gå til mappa over apertium-xxx-yyy, som hos meg heiter apertium

git clone https://github.com/apertium/apertium-kaz-kir.git

med eit anna par enn kaz-kir viss du heller vil ha det (t.d. sme-deu, …)

for lang-sma, …:


./configure --enable-apertium ...

make

for sme-sma, sme-nob, and sme-smj:


git switch rtx

./autogen.sh --with-lang1=../lang-xxx/tools/mt/apertium --with-lang2=../lang-yyy/tools/mt/apertium

./configure --with-lang1=../lang-xxx/tools/mt/apertium --with-lang2=../lang-yyy/tools/mt/apertium

./configure --with-lang1=../lang-sme/tools/mt/apertium --with-lang2=../lang-sma/tools/mt/apertium

Concrete example, sme-smj


./configure --with-lang1=$GTLANGS/lang-sme/tools/mt/apertium --with-lang2=$GTLANGS/lang-smj/tools/mt/apertium

number = (ND sg) sg du pl ; ! if number is missing, use <ND> or <sg>

when analyzing (the source language): use for unknowns
when generating (the target language): use for unknowns

number > number : du pl ;   ! replace all <du> with <pl>

when outputting number, always replace with

1.gender/sl means the same as <clip pos="1" side="sl" part="gender"/>

prpers<prn><pers><p3><sg>/el<prn><pers><p3><sg>/Albert<np><m><sg>

 SIDE_SOURCES = sl tl ; ! change default order of unspecified clips

 SIDE_SOURCES = tl ; ! if you just want tl when unspecified (1.gender), and have to be explicit (1.gender/sl) when you want sl

 NP -> det n { 1[number=2.number/sl] _ 2 } ;

 NP -> adj n.number = <adj> <n><number> ! don't do this :)

 NP -> adj n.sg = <adj> <n><sg>

 NP -> adj n.$number = <adj> <n><sg/du/pl>

 NP -> adj n [$number=2.number] { 1 _ 2 } ;

 NP -> det adj n { 1 _ 2 _ 3 } ;

 NP -> n { 1 } ;

 sg_or_pl = sg pl ;

 NP -> adj n.[sg_or_pl]

NP{ AP{ adv adj } n }

 

     NP

    /  \

   AP   n

  / \

adv adj

! define NP's tags

NP: <NP>.number.gender ;

! define NP's structure

NP -> adj n.$number.$gender { 1 _ 2[number=$number,gender=$gender] } ;

! when analyzing, find an <adj> then an <n>, combine them into an NP phrase, give this NP node the number and gender tags by taking them from the noun. When generating this NP, output the adjective, then a space, then the noun, and set the number tag of the noun to be the number tag of the NP and the same for gender (since these tags may have been changed by something elsewhere in the tree).

NP -> adj %n { 1 _ %2 } ;

! as above, but don't explicitly list the tags to be copied at each step

example: https://wiki.apertium.org/wiki/File:Recursive_Transfer_Hobbit_Example.pdf

VP -> %vblex DP { 1[tense=$tense, person=$person, number=$number] _ 2 } |

##%vblex DP= analyse 

{ ... } = genrerert output 

3 output: 

## 1=%vblex

_ = melllomrom

## 2 =  DP

## % = ta verdien

      adv %VP (if (1.lem/sl = there) { %2 } else { 1 _ %2 } ) |

      adv %VP { (if (1.lem/sl = there) [ 1 _ ]) %2 } |

      PP %VP { 1 _ %2 } ;

      eksempel: 

PP -> pr DP { 1 _1 2 } ; (mellomrom i output) "i skogen" 

NP -> n guio n { 1 2 3 } ; "skuvle-busse" guio = bindestrek

<b pos="1"/> = _1 #old way

Kevins rule: (ikke mellomrom i output)

showing recursiveness

a_cmp = cmp cmp-split ;

N -> %n ?(1.a_cmp = "") { %1 };  ! matches ^møte<n>$

N -> n.*.cmp %N { 1 %2 } ; ! matches ^kake<n><cmp>$ followed by N

 ! oste-kakemøter ^ost<n><sg><cmp-split>$^kake<n><sg><cmp>$^møte<n><pl>$

 ! analyses into this tree structure:

                        ^møde<N><pl>{

                                ^ost<n><sg><cmp-split>/ost<n><sg><cmp-split>$

                                ^møde<N><pl>{

                                        ^kake<n><sg><cmp>/kage<n><sg><cmp>$

since the exact same pattern applies for both rules, rule 125 will never apply

rule ordering: either more specific first or put a weight

VP -> 2: vblex.*.neg { 1 } ; #verb phrase could be a negative verb, pick the higher weight

habitive structure:

Danielis lea XXX
“On daniel is XXX” = Daniel has

@ADVLhab→   (@ADVL> <hab>)

@←SUBJext
Beavddis @ADVL-ine→   lea    dihtor @←SUBJext.

Loc  @ADVL-ine→ @ADVL-ela→   Adv @ADVLcs-ela→

NP -> %n { %1[case=(if (1.case = loc and (1.function = "@←ADVL-ine" or 1.function = "@→ADVL-ine")) ine
                if (1.case = loc and (1.function = "@←ADVL-ela" or 1.function = "@→ADVL-ela")) ela
                else 1.case)] } ;

so:

function = "@→SUBJ" "@←OBJ" "@→ADVL" "@→ADVL-ine" "@→ADVL-ela" ;

NP: _.function;

S -> NP."@→SUBJ" VP |
 VP NP."@←SUBJ"

NP: _.number ;
VP:_.number ;
S: _;
NP -> %n { 1 } ;
! send number from input verb to VP, by default get it back again the same, unless the next phrase up changes it
VP -> %vblex { %1 } ;
! if NP and VP disagree in number, change VP
S -> NP VP { 1_ 2[number=1.number] } ;

Analysis:
  S
/  \
  NP    VP
  |     |
  n   vblex
n has number from input
vblex has number from input
NP has number from n
VP has number from vblex
S doesn't have number

Generation
NP    VP
|     |
n   vblex
NP has the number it had before
VP now has the number from NP

NP -> %n { 1[poss=$poss] } ;

NP: _.number.case.poss ;

NP -> %n { %1 } ;
same as
NP -> %n { 1[number=$number,case=$case,poss=$poss] } ;

NP -> %n { %1[number=sg] } ;
same as
NP -> %n { 1[number=sg,case=$case,poss=$poss] } ;

- Gålmås båhti fæsstaj.

NP -> 2: %n.coll [$number=pl] { 1 } ;
! if we have a collective numeral, apply this rule rather than the normal NP -> n rule (weight 2 so it wins) when copying tags to the phrase, don't copy the morphological <sg> but rather always put <pl> so that we don't screw up verb agreement, and don't put % inside the {} so that we keep the input tags and don't override the <sg> tag on the noun

change noun based on the verb, so we want to attach it to the VP so write a rule to attach an illative NP

search for the last VP rule and add a

and a new condition

copy lemma of the verb to the phrase so we can access it for the valency

we need change from illative to a prepositional phrase with “an”

adding a weight “2:” because there is a conflicting rule change illative case if the lemma is in the set verb_ill_to_an

add a new case to the set of case the NP gets a new case tag from the rule “pr_an”

case = (CD nom) nom acc dat gen ill loc com ess CD pr_auf_acc pr_auf_dat pr_an_acc ;
verb_ill_to_an = "sich gewöhnen" ;
VP -> 2: %VP NP.*.ill { 1 _ 2[case=(if (1.lem in_cl verb_ill_to_an) pr_an_acc else 2.case)] } ;
NP -> 2: %N (if ($case = pr_auf_acc) { auf@pr.acc _ %1[case=acc] }
         ! assume that we came from a PP and should thus be definite
         if ($case = pr_an_acc) { an@pr _ 1[maybe_art](def=def) %1[case=acc] }
         else { %1 }) ;

VP -> %lea@VP vejolaš@adj.*.nom { %1[lem=2.lem/tl] } ;

son lea vihtta jagi boaris. > Sån la vidá jagák

coordination

! agree with noun nearest the verb (if the verb comes after)
NP -> %NP cnjcoo NP [$number=3.number] { 1 _2_ 3 } ;

! number is dual if both conjuncts are human (translating to Sámi)
conj_dual = sem_hum sem_org sem_fem sem_mal sem_sur;
NP -> %NP cnjcoo NP
  [$number=(if (1.number = sg and 3.number = sg and
                1.sem in conj_dual and 3.sem in conj_dual) du
