Semantic Navigation Through Semi-structured Information
This flexible and generic data model presents several opportunities for improving information retrieval. Searches for information generally involve a dialogue between the user and the computer. The user starts somewhere and follows a sequence of navigation steps (e.g., issuing a query, looking at the results, refining the search parameters, etc.) until the desired information is found. A user interface can help this navigation process by suggesting useful steps to be taken next, such as specifying particular ways to refine the query.
