On Heterogeneous Database Retrieval: A Cognitively Guided Approach

Ramayya Krishnan, Xiaoping Li, David Steier, Leon Zhao
2001 Information systems research  
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  ...

Beyond retrieval: A proposal to expand the design space of classification

Melanie Feinberg
2011 NASKO  
Beyond retrieval: A proposal to expand the design space of classification.  ...  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.  ...

SIREA: Image Retrieval Using Ontology of Qualitative Semantic Image Descriptions

Saqib Majeed, Zia ul Qayyum, Sohail Sarwar
2013 2013 International Conference on Information Science and Applications (ICISA)  
Our research addresses semantic retrieval of images from plethora of image dumps by imparting human cognition in the image retrieval process.  ...  Effectiveness of our approach is evident from retrieval accuracy and relevance of images retrieved from huge repository of natural scenes.  ...  These surveys reveal one important aspect that almost all existing approaches rely on using low level image feature, categorization and retrieval.  ...

State of the Art of User Simulation approaches for conversational information retrieval [article]

Pierre Erbacher and Laure Soulier and Ludovic Denoyer
2022 arXiv   pre-print
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.  ...
