|FIRE - Query Refinement|
|Finally, when the searcher wishes to issue a new
refined search, the system includes its term suggestions
automatically but allows the searcher to delete or modify
them according to her understanding of the query. This
step of the dialog takes place in the same form as the
initial graphical query.
In this example, the FIRE engine has included an addition set of terms including ibms, microsoft, operating, and industry. The searcher has determined that industry is not useful. Therefore she deletes that term before re-submitting the query.
This modified query is sent to the search engine and the process is continued. Note that the documents which were previously marked as "relevant" will automatically appear in the relevant list so that the searcher need not look through them again. Likewise, any trashed documents which are still returned will be hidden in the trash can so the searcher will not be bothered with them.
We have found that the FIRE query refinement system provides significant aid for textual information retrieval. Using its suggestions usually improves the precision of a search by 30% without significantly reducing recall. But more importantly, the system helps searchers understand their queries better and stimulates their thinking by providing hints as to the differences between relevant and trash documents.
