* <b> Pico Accentuation and Phrasing </b>\n
*
internal buffers:
- headx : array for extended item heads of fixed size (head plus
index for content, plus two fields for boundary strength/type)
- cbuf : buffer for item contents (referenced by index in
headx).
0. bottom up filling of items in headx and cbuf
1. phrasing (right-to-left):
e.g. from WP WP WP WP WP PUNC WP WP PUNC WP WP WP PUNC FLUSH \n
e.g. to BSBEG WP WP WP BPHR3 WP WP BPHR1 WP WP BSEND BSBEG WP WP WP BSEND BTERM \n
|1 |2 |3 |4 \n
2-level bound state: The internal buffer contains one primary phrase (sometimes forced, if buffer
allmost full), with the trailing PUNCT item included (last item).\n
If the trailing PUNC is a a primary phrase separator, the
item is not output, but instead, the bound state is set to PPHR, so that the correct BOUND can
be output at the start of the next primary phrase.\n
Otherwise,
the item is converted to the corresponding BOUND and output. the bound state is set to SSEP,
so that a BOUND of type SBEG is output at the start of the next primary phrase.
trailing PUNC item bound states \n
SSEP PPHR \n
PUNC(SENTEND, X) B(B,X)>SSEP B(P1,X)>SSEP (X = T | Q | E) \n
PUNC(FLUSH, T) B(B,T)>SSEP* B(P1,T)>SSEP \n
PUNC(PHRASEEND, P) B(B,P)>PPHR B(P1,P)>PPHR \n
PUNC(PHRASEEND, FORC) B(B,P)>PPHR B(P1,P)>PPHR \n
If more than one sentence separators follow each other (e.g. SEND-FLUSH, SEND-SEND) then
all but the first will be treated as an (empty) phrase containing just this item.
If this (single) item is a flush, creation of SBEG is suppressed.
- dtphr phrasing tree ("subphrasing")
determines
- BOUND_PHR2
- BOUND_PHR3
- boundary strenghts are determined for every word (except the
first one) from right-to-left. The boundary types mark the phrase
type of the phrase following the boundary.
- number of items actually changed (new BOUND items added): because
of fixed size without content, two fields are contained in headx
to indicate if a BOUND needs to be added to the LEFT of the item.
-> headx further extended with boundary strength and type info to
indicate that to the left of the headx ele a BOUND needs to be
inserted when outputting.
2. accentuation:
- number of items unchanged, content unchanged, only head info changes
-> changed in place in headx
