  2. Overview • Problem: schema matching • Element-level • Structure-level • Experiment Applications • Course Schedule • Faculty Member • Methods • Name Matcher • Naïve Bayesian Classifier (NB)

  3. Element-level Matching Source Schema Target Schema

  4. Experimental Methodology • Application Data (5 schemas) • Target Schema (1 schema) • Source Schemas (4 schemas) • Training schemas (3 schemas) • Test schema (1 schema) • Test Number ( 20  2)

  5. Method 1 : NB • Content-based matcher

  6. Source Schema Method 1 (Cont.) • Training Phase Target Schema

  7. Method 1 (Cont) Source Schema • Classification Phase

  8. Method 2: Name Matcher Target Schema • Schema Element Names • Training Phase start_time: start_time start start time
