Automatic Mapping Among Lexico-Grammatical Annotation Models (AMALGAM)

Parsing schemes

The differences are much greater between parsing schemes for full syntactic structure annotation. The following are parses conformant to the parsing schemes of several large-scale English TREEBANKS or CORPORA of parsed English text:

==> EAGLES <==
[S[VP select [NP the text [CL[NP you NP][VP want [VP to protect
VP]VP]CL]NP]VP] . S]


==> ECG-BoE <==

        "select" <*>

        "text" N NOM SG @OBJ
""
        "you"  PRON PERS NOM SG2/PL2 @SUBJ
""
        "want"    
 V PRES -SG3 VFIN  @+FMAINV
""

        "protect"  V INF @-FMAINV

YF      +.      -       O]



There is even greater diversity in the parsing schemes used in rival
NLP parsing programs. The example sentence was actually selected from a
test-set used at the Industrial Parsing of Software Manuals workshop (University
of Limerick, 1995); it is one of the shortest test sentences, and hence
ought to be one of the most grammatically straightforward and uncontrovertial
(!) 

The following are outputs of several rival NLP parsing programs, given
the example sentence to parse: 

==> alice <== 

Fragment No. 1 

>From 0 To 5 



(SENT (SENT-MOD (UNK-CAT "Select") (NP (DET "the")
(NOUN "text"))) 

(SENT (VP-ACT (NP "you") (V-TR "want")) (NP NULL-PHON)))

(SENT-MOD (UNK-CAT "to") (NP "protect"))
