1. Mapping Target Schemas to Source Schemas Using WordNet Hierarchies Master’s Thesis Proposal David Jackman

2. Biskup-Embley Approach PublicationAbstract Title Author Publication Year Publication Name 1 1 1 0:1 1:* has Target View JournalEditor Title Publication Date 1 0:1 1:* has Article TitleAuthor has Abstract 1 1:* 1 1 0:1 1:* 1 has Source Schema Other Source Schemas

3. WordNet Background A lexical database for English Developed at Cognitive Science Lab at Princeton University Has become a standard in natural language research English terms are organized into synonym sets, each representing one underlying lexical concept

4. Framework Mapping Process Target Schema (XML) Integration Mappings (XML) Source Schema (XML)

5. Mapping Process Written in Java For this research, two procedures are used: –First creates mappings with a WordNet score –Second adds a context score to those mappings

9. Experiments Run in 4 domains: Music CDs, Genealogy, Real Estate, Travel Source schemas taken from existing web sites Target schemas taken from standard XML DTDs or created by independent third parties Combined WordNet & Context scores compared against mappings determined by a human expert

10. Conclusion Data integration process can become more automatic Combination with research being done in data extraction and data warehousing
