Weekly Report Semantic Web Research Center Duhyeon Jin 2011-3-24
Contents • Goal & Progress in last week • Previous discussion • Improvements • Plan
Goal CoreNet Case frame for 1,144 adjective Sense Case frame for 765 Verb Sense Making case frame for “Predicate nominal” +”하/되/시키” Case frame construction Verbs for 675 Predicate nominal More than 300 case frames per each Verbs
Last progress • Selected 675 predicate nominals • Made instruction for construction of case frames • Test case for 3 verbs ‘생각하다, 시작하다, 사용하다’ • Extracted 300 raw case frames per 3 verbs raw case frame: arguments is not assigned to CoreNet concept system
Previous Discussion • How to build case frames effectively? • 1. Clustering Verbs with its concepts -> easy to work • 2. Select non-debatable sentences
Improvements • Expanding verb entries by Sejong Dictionary • Clustering Verbs with CoreNet concepts
Expanding verb entries with Sejong Dictionary • In SejongDictionary: • 15,181 verb entries are available • Useful information: arg-structure, semantic tag for arguments
Expanding verb entries with Sejong Dictionary • Extracted verb entries for each Predicate nominals: 1,516 verbentries are extracted Sejongdictionary • Extracted argument structures to refer 편입하다 편입 편입되다 편입시키다
Clustering Verbs with CoreNet Concepts • Assigning 657 verbs to 370 CoreNetconcepts • Instruction: • 1. Follow Corenet concept of predicate nominal • 2. Refer to Sejong semantic tag
Problems • Homonyms and polysemy (ex: 소화하다) • Reliability: verification for concept assigning
Plan • Complete assigning concepts target words( ~되다, ~시키다) • Confirm & Start from one cluster
