ICEBERG: Exploiting Context in Information Brokering Agents
نویسندگان
چکیده
The research reported in this paper has both a scientific and a commercial aim. The scientific interest is to explore the use of contexts in order to improve the quality of information brokering. In this paper it is shown that contexts in information brokering can be exploited to enable four directions of query reformulation: up and down (standard query expansion) and sideway reformulations of the user request that can even involve going from one context to another.
