d99a9cbce9 different handling of space tokens 
space tokens are now always attached to the previous non-space token
there are two exceptions:
leading space tokens are attached to the first following non-space token
in input that consists exclusively of space tokens, the last space token
is the head of all others.

3448cb40a4 integrated pseudo-projective parsing into parser 
- nonproj.pyx holds a class PseudoProjectivity which currently holds
  all functionality to implement Nivre & Nilsson 2005's pseudo-projective
  parsing using the HEAD decoration scheme
- changed lefts/rights in Token to account for possible non-projective
  structures

04177debd0 * Unwind limit to sentence boundary detection that prevents it from inserting boundaries on whitespace. Replace it with a check for whitespace in StateClass.fast_forward, so that whitespace is LeftArced when it's on the stack. This should prevent the previous problem of whitespace-only sentences. Should fix Issue #184, but may cause further problems. Needs testing. 2016-01-19 02:54:15 +01:00

aec130af56 Use util.Package class for io 
Previous Sputnik integration caused API change: Vocab, Tagger, etc
were loaded via a from_package classmethod, that required a
sputnik.Package instance. This forced users to first create a
sputnik.Sputnik() instance, in order to acquire a Package via
sp.pool().

Instead I've created a small file-system shim, util.Package, which
allows classes to have a .load() classmethod, that accepts either
util.Package objects, or strings. We can later gut the internals
of this and make it a proxy for Sputnik if we need more functionality
that should live in the Sputnik library.

Sputnik is now only used to download and install the data, in
spacy.en.download

20fd36a0f7 * Very scrappy, likely buggy first-cut pickle implementation, to work on Issue #125: allow pickle for Apache Spark. The current implementation sends stuff to temp files, and does almost nothing to ensure all modifiable state is actually preserved. The Language() instance is a deep tree of extension objects, and if pickling during training, some of the C-data state is hard to preserve. 2015-10-13 13:44:41 +11:00
Matthew Honnibal
9dd2f25c74 * Fix Issue #131: Force whitespace characters to attach syntactically to previous token, and ensure they cannot serve as stand-alone 'sentence' units. 2015-10-10 15:53:30 +11:00
Matthew Honnibal
8b39feefbe * Add dependency post-process rule to ensure spaces are attached to neighbouring tokens, so that they can't be sentence boundaries 2015-10-10 15:32:13 +11:00
Matthew Honnibal
0e24d099a1 * Fix L/R edge bug, by ensuring l_edge and r_edge are preset, and fixing the way the edge update in del_arc. Bugs keep arising here because the edges are absolute positions, where everything else is relative. I'm also not 100% convinced that del_arc is handled correctly. Do we need to update the parents? 2015-09-09 03:40:44 +02:00

5edac11225 * Wrap self.parse in nogil, and break if an invalid move is predicted. The invalid break is a work-around that papers over likely bugs, but we can't easily break in the nogil block, and otherwise we'll get an infinite loop. Need to set this as an error flag. 2015-09-06 04:15:00 +02:00
