37 The most common syntactic categories


39 The DanGram system in current numbers Lexemes in morphological base lexicon: (equals about full forms), of these: proper names: (experimental) polylexicals: 460 (+ names and certain number expressions) Lexemes in the valency and semantic prototype lexicon: Lexemes in the bilingual lexicon (Danish-Esperanto): Danish CG-rules, in all: morphological CG disambiguation rules: syntactic mapping-rules: syntactic CG disambiguation rules: (plus 429 bilingual rules in separate MT grammars, and a smaller number of semantic case-role and proper name- rules in the semantics and name grammars) Danish PSG-rules: 490 (for generating syntactic tree structures) Performance: At full disambiguation (i.e., maximal precision), the system has an average correctness of 99% for word class (PoS), and about 96% for syntactic tags (depending, on how fine grained an annotation scheme is used) Speed: full CG-parse: ca. 400 words/sec for larger texts (start up time 3-6 sec) morphological analysis alone: ca words/sec

40 VISL parsing tools Preprocessing: word- and sentence boundaries, polylexicals Lexicon and rule based morphological analysis: Inflexion, derivation, composita recognition Postprocessing: Valency and semantic potential Morphological contextual disambiguation (CG) Syntactic mapping og diambiguation (CG) Names CG, feature propagation CG, Case role-CG PSG-overbygning: Teaching, Arboretum, Floresta
