[erg] a question of parenthesised numbers

[Stephan Oepen]

hi david,

how exactly do you invoke PET nowadays?

$ echo "a person (1234543265)" | cheap -sm -repp -cm -default-les=all
-verbose=3 english.grm

[...]

derivation[1] (0):a person (1234543265)

(117 np_frg_c 0 0 3 [root_inffrag]
  (116 sp-hd_n_c 0 0 3
    (41 a_det/d_-_sg-nmd_le 0 0 1 []
      (31 "a" 0 0 1 <0:1>))
    (114 hdn-n_prnth_c 0 1 3
      (98 n_ms-cnt_ilr 0 1 2
        (81 person_n1/n_-_mc_le 0 1 2 []
          (30 "person" 0 1 2 <2:8>)))
      (105 num_prt-det-nc_c 0 2 3
        (95 w_lparen_plr 0 2 3
          (93 w_rparen_plr 0 2 3 [w_lparen_plr]
            (88 generic_card_ne/aj_-_i-crd-gen_le 0 2 3 [w_rparen_plr
w_lparen_plr]
              (36 "(1234543265)" 0 2 3 <9:21>))))))))

there are in total eight analyses, all with the number
as a cardinal adjective.  arguably, we should maybe
also allow an analysis as an identifier NE, but that
would cost substantially in ambiguity ...

you can look at tmr/ne{1,2,3}.tdl in the ERG source
for the patterns we recognize through what we call
lightweight named entity recognition.

best, oe
