  37. The most common syntactic categories

  38. The DanGram system in current numbers Lexemes in morphological base lexicon: 146.342 (equals about 1.000.000 full forms), of these: proper names: 44839 (experimental) polylexicals: 460 (+ names and certain number expressions) Lexemes in the valency and semantic prototype lexicon: 95.308 Lexemes in the bilingual lexicon (Danish-Esperanto): 36.001 Danish CG-rules, in all: 6.233 morphological CG disambiguation rules: 2.678 syntactic mapping-rules: 1.701 syntactic CG disambiguation rules: 1.854 (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. 1000 words/sec

  39. 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

  40. Research projects • SHF 1999-2001: CG, syntax & semantics (da,en,po) • AC/DC 1999-?: Portuguese CG-corpora • Floresta 2000-?: Portuguese treebank • DSL 2001-?: Korpus90/2000 (Danish CG-corpora) • Arboretum 2002-?: Danish treebank • PaNoLa 2002-2003: Integration of Nordic CG research • Nomen Nescio: Automatic named entity recognition
