Collaboration of Search Engine and Shared RDF Bookmark
  - The Search Result from the search engine is ...
 "URIs concerned to the given keywords, generated
      by the search engine."
- The Bookmark of the user is ...
 "highly trusted URIs generated by the user."
- The actual function of this system is filtering the search result.
      But its definition is:
 "Automatic collaboration of search result provided in RDF and
      bookmark information provided in RDF, based on the information of
      their origin (provenance URI)".
