| Apr 6, 2017 at 22:33 | comment | added | amI | That Wiki tree is wacko -- and why is the subject 'Sarah' shown as part of the predicate? Nested brackets can only represent 'flat' trees. Perhaps something like { {1:Whom}{2:has} { {Sarah}{2_{been{tutoring{_1}}}} } } to show the displacements, but is this ever useful? | |
| Apr 5, 2017 at 13:03 | comment | added | StoneyB on hiatus | I'm strictly an amateur in this, winging it for my own purposes, so most of the literature I've encountered is too technically formalized for me to judge its validity; and the notations and formalizations are tied to specific theories/approaches I'm usually unfamiliar with. (Your notation, for instance, where a word acts as its own parent, is very odd to me!) Consequently I'm not comfortable putting up an Answer, as if I actually knew what I was talking about. | |
| Apr 5, 2017 at 12:48 | comment | added | player.mdl | Thought as much :) Are you aware of any literature that explicitly discusses this limitation? Would love to read up more. Also please add your comments as answer. I'd like to accept it. | |
| Apr 5, 2017 at 11:56 | comment | added | StoneyB on hiatus | Bracketing presupposes that there is no discontinuity. To accommodate discontinuity you need some sort of anaphoric device which correlates an existing remote constituent and a local 'empty' constituent. After that it's just a matter of telling your parser how to represent that, whether as line crossing or movement arrows or some other convention. | |
| Apr 5, 2017 at 10:57 | comment | added | player.mdl | There is no movement to speak of in my case. I'm coming from a computational perspective - generating training data for sentence parsers. I need to formally represent discontinuous surface structures. | |

| Apr 4, 2017 at 6:20 | comment | added | StoneyB on hiatus | Fersher. Depends on your theory: does it hold that what's "actually" there is a discontinuity or that what's there is "actually" a displacement-and-gap? Bracketing is designed for the latter. | |
| Apr 4, 2017 at 4:55 | comment | added | player.mdl | Hmm...I don't believe this solves the problem. This simply rearranges the tree. | |
| Apr 4, 2017 at 1:33 | comment | added | StoneyB on hiatus | Why not represent 'movement' as actual movement? MIles Shang's Syntree does this to some extent: try entering [? [text [S [np [Who_A]] [aux.inv [aux [has_B]] [vp [np.su Sarah][vp.prf [auxHAVE.3s _<B>][vp.prg [auxBE.pa.ppl been][vp [v.pr.ppl tutoring][np.do _<A>]]]]]]]] [punc ?]]. | |
