Searching goes beyond navigating because users are typically looking for answers (goal-oriented) and more automation is involved (moving beyond simple URI dereferencing in a browser to relying on some computer agent for results). |
|
When we search, we would like to take advantage of any data preprocessing a system has completed in advance, such as discovering, sorting, filtering, indexing, and storing. |
|
By entering a set of search parameters, we are loosely defining what information we wish to retrieve and how we wish to retrieve it. |
|
Searching is only as useful as the keywords on which it is based. In addition, there is no one Semantic Web search engine that has indexed every URI-accessible RDF document and RDF store, and it is possible that a particular engine isn’t crawling the proper data store. |
