  2. Contents • Last Discussion • How can extract argument patterns? • Josa & thematic role • Current Progress

  3. Last discussion • 1. Show raw argument data of Treebank  not N1, N2.. Show every connected args with its ‘josa’ • 2. Decide representative ‘josa’ and find derivative ‘josa’ • 3. Classify ‘josa’ with the specific purpose(Think the translation case)

  4. How can extract argument patterns? • Sejong Treebank has only 4 argument types • No other types of arguments Predicate 생각했다 NP_CMP NP which can be subject NP_SBJ NP which can be subject 예쁘다고 NP_AJT NP which can be subject 철수가 NP_OBJ NP which can be subject 예전에 영희를

  5. 생각하다 NP_SBJ 형/은 S_CMP 인생이…/다고

  6. What kind of Korean stems are involved to this syntactic category? Extractedfrom Sejong Treebank • NP_SBJ •  이/가, 은/는, 께서, 도, 이란, 이야말로, 만, 까지, 마다, 나, 란, 조차, 밖에, 부터, 두, 이나, 마저, 와 • NP_OBJ •  을/를, 조차,까지, 도, 은/는, 이나마, 마저, 나/이나, 두, 부터, 과 • NP_AJT •  으로, 에서, 도, 로써, 에, 은/는, 로, 로부터, 밖에, 과, 처럼, 에서부터, 부터, 만, 으로서, 까지, …… • NP_CMP • 라고, 다고, 이라고, 라, 라며, 리라, ….

  7. Related researches on Korean ‘josa’ and thematic role • 조정미· 김길창(1996), 한국어 의미 해석 시 중의성 해소에 대한 연구 • 강신재 · 박정혜(2003), 대규모 말뭉치와 전산 언어 사전을 이용한 의미역 결정 규칙의 구축 • 임동훈(2004) 한국어 조사의 하위 부류와 결합 유형  Syntacticstems, semantic stems, postpostions, delimiters and combinations of stems Syntactic Semantic Delimiters, etc 이/가, 을/를 에, 에게, 에서, 으로/로, 와/과 만, 까지, 은/는, 나, 도…

  8. Postpositions, Delimiters and particles • Postpositions: 만, 까지(to), 다가, 밖에, 부터(from), 조차, 처럼(like), 같이(like), 보다(than), 만큼, 뿐, 대로..  can make an adjunct and have a thematic role • Particles(delimiters): 은/는, 이야/야, 도, 이나/나, 이라도/라도..  can be ignored at case and thematic role level

  9. Cho & Kim 1996

  10. Kang & Park(2003) • Agent : 이/가, 에서, 에게 • Theme : 이/가, 을/를, 에 • Experiencer: 이/가, 에게 • Companion: 와/과 • Source: 에서 • Goal: 에, 로/으로, 에게 • Instrument: 로/으로 • Reason: 에, 로/으로 • Reciepient: 이/가, 에게 • Appraisee: 로/으로 • Criterion: 에서, 와/과 • Degree: 만큼 • Direction: 로/으로 • Time: 에, 로/으로 • Path: 로/으로 • Material: 로/으로

  11. The List of thematic roles inCoreNet In the previous version of CoreNetcaseframe database, Supposed following thematic roles. Minimum number of ‘josa’s are presented. 이/가, 로/으로, 에서, 에게서, 에, 을, 에게,한테, 와, 에 대해, 보다, 만, 로부터, 라고, 를 향해,

  12. Josa & Thematic role matrix

  13. Allcases of josa in the data • Excluding delimiters, we can find 61 types of josaand combinations of josa. • There will be more combinations with the more data.

  14. Allcases of josa in the data

  15. example • Constructed patterns are  A가 B를동반하다  A가 B를 C에 동반하다.

  16. Current progress • 78 verbs for 675 verbs • Planning to construct 20 verbs per a day
