  1. TAGSET REDUCTION BASED ON THE FEATURES NEEDED FOR THE SLOVENE SKETCH GRAMMAR Simon Krek Amebis, d.o.o., Kamnik, Slovenia Jožef Stefan Institute, Slovenia

  2. We'll talk about... • Slovene morphology • Tagsets forSlovene • MTE-JOS tagset • Slovenecorporaandlexicaldatabase • SketchgrammarforSlovenelexicaldatabase • MTE-JOS tagsetreduction • Taggingresultswithreducedtagsets • Tagsetreduction: conclusions

  3. Slovenemorphology • Theextremecaseofadjective: • inflectionalcategories • case: 6 • gender: 3 • number: 3 (dual!!) • definitiveness: 2 • only nominative & accusativemasculinesingular • degree: 3 • forms • 56 forpositivedegree • 164 forall three degrees

  4. Adjective "disgusting"

  5. 12 combinationsfor -ih

  6. Tagsetstandardization • Eagles (1993-1996) • Multext (1994-1996) • Multext-East (1995-1997) • 1997 - ver. 1 MTE: Bulgarian, Czech, Estonian, Hungarian, Romanian, Slovene,English (7 languages) • 2010 - ver. 4 Mondilex: Bulgarian, Croatian, Czech, English, Estonian, Hungarian, Macedonian, Persian, Polish, Resian, Romanian, Russian, Serbian, Slovak, Slovene,Ukrainian (16 languages)

  7. From MTE to JOS • JOS project (2007-2009) • MTE principles: positionalattributesetc. • Fromsyntax to morphology • Reorderingofattributes to make tagsshorter • Non-trivialmapping • 12 categories, 15 attributes, 56 values • 1.902 tags

  8. Slovenecorpora • FIDA (2000) • 100 million • MTE tagset, rule-basedtagger • FidaPLUS (2006) • 620 million • MTE tagset (2006) – rule-basedtagger (SketchEngine) • JOS tagset (2010), rule-based & statistical + metatagger • Gigafida (2011) • 1.1 billion • JOS tagset (2011) – statisticaltagger (SketchEngine – beforesummer?)

  12. Tagsetreduction – ver. 15 • 12 categories: 64 tags • verb • type: main, auxilliary • form: infinitive, supine, participle, present, future, conditional, imperative • person: 1st, 2nd, 3rd • negation: yes, no • noun • type: common, proper • case: nominative, genitive, dative, accusative, locative, instrumental • adjective • type: general, participle • case: nominative, genitive, dative, accusative, locative, instrumental • prononun • type: personal, possessive, demonstrative, relative, reflexive, general, interrogative, indefinite, negative

  13. Tagsetreduction – ver. 16 • 10 categories: 154 tags • number (3/2): noun, verb, adjective • degree (3): adjective, adverb • type: numeral (3), adverb (3), conjuction (2) • case (6): preposition • number: adjective = no dual -> more than 1

  14. Statisticaltagger – threetagsets • 500.000 word training corpus

  15. Conclusions • 2.94% = 32,340,000 tokens (1.1 billioncorpus) • 0.43% = 4,730,000 tokens (1.1 billioncorpus) • significant: unknownwords • not significant: categories • Reduced tagset: automatic extraction of data from the corpus • Full tagset: manual corpus analysis in Sketch Engine & other concordancers
