On Heterogeneous Database Retrieval: A Cognitively Guided Approach
2001
Information systems research
Preserved Fulltext
We propose a cognitively-guided approach for developing an information retrieval agent that takes the user's information request, identifies relevant information sources, and generates a multidatabase ...
Retrieving information from heterogeneous database systems involves a complex process and remains a challenging research area. ...
Building on the mediator-based approach [Wiederhold, 1992] , in this paper we propose solutions to two key problems encountered in the design of information retrieval agents for heterogeneous databases ...

A consequence of an expanded design space is that standard classification manuals and guides become insufficient support for the design process; a new research area might be the facilitation of problem-setting ...
Why focus on retrieval when classifications can do more? However, if one is interested in expanding the classification design space, the current guides and methods provide limited assistance. ...

Conversational Information Retrieval (CIR) is an emerging field of Information Retrieval (IR) at the intersection of interactive IR and dialogue systems for open domain information needs. ...
However, training these systems by reinforcement learning on users is not feasible. One solution is to train IR systems on user simulations that model the behavior of real users. ...
First user modeling approaches in IR were based on cognitive approaches. ...
