1. Easing Semantic Data Publishing and Processing Using Semantic MediaWiki and RDFa Jin Guang Zheng

2. Motivation Problem Publishing and consuming linked data require substantial work and the familiarity of semantic technologies. Solution Reduce it by using Semantic MediaWiki & RDFa Develop an extension converts SMW Data -> RDFa data & RDFa Data -> SMW Data Benefit For Publisher Easy publishing RDFa data; For Consumer Rich set of SMW extension to cosume data; RDFa-aware tools and services

3. More Advantage of Combining Semantic MediaWiki & RDFa Publishing SMW data (which are mainly consumed internally by the wiki) as RDFa facilitates breaking down barriers among wiki based data sources and other applications (e.g., search engines); Taking the advantages of SMW's user-interactive platform, the extension offers owners an easy way to publish social, dynamic semantic data without requiring users the knowledge of semantic technologies; By supporting both importing and exporting RDFa data for SMW, we are able to use the low-cost semantic application development environment enabled by SMW to process, merge and republish RDFa data.

6. Data-Gov Catalog Without RDFa Description of the search result doesn’t present user with useful information

7. Data-Gov Catalog With RDFa With RDFa technology, we were able to present some interesting information to the user

8. Future Work with Faceted Browsing Instead of hard code the RDFa data to be presented, use Faceted Browsing technology to create an interactive environment for user to browse the RDFa data + enhance search experience.

9. RDFa + Faceted Browsing Web pages With RDFa Data Web pages With RDFa Data Query RDFa Data
