nx_depparse.nx

nx_depparse.nx -- a DEPENDENCY PARSER for the estate (rung IM28's parse-feature lever: DLIREC, the SemEval-2014 restaurants winner, took its exceed from dependency features, and nx_capsearch over 7,437 organs found no parser here -- every hit was the software-dependency homonym). ARC-STANDARD transition parsing (SHIFT, LEFT-ARC(rel), RIGHT-ARC(rel)) with a greedy AVERAGED PERCEPTRON over the actions, integer weights only (nofloat), trained by the STATIC ORACLE on a CoNLL-U treebank read by nx_postag's reader (HEAD and DEPREL columns), with POS tags from nx_postag's own predictions on the training sentences, so train and test see ONE tag generator. Relation labels are the UD base names (before ':'), interned in first-seen order at training. Non-projective training sentences (the static oracle cannot reach them) are SKIPPED and counted. A single-root constraint: the root attaches only once the buffer is empty. dp_parse_stream parses ANY tagged token stream, which is how the aspect model consumes it. FEATURES (Zhang and Nivre 2011's core): word and tag of s0, s1, b0, b1, b2, their word+tag pairs, tag pairs and triples across the stack top and buffer front, the tags of s0's and s1's leftmost and rightmost children, word pairs s0+b0 and s1+s0, the bucketed distance s1..s0 with their tags, and the relation of s0's rightmost child. license_tier: ORIGINAL No hw writes (Rule 26).
