Exploiting task-document relations in support of information retrieval in the workplace

Luanne Freund
2008 SIGIR Forum  
Existing systems are designed to retrieve information that is relevant to the query, but are not capable of identifying information that is well-suited to the context and situation of a search.  ...  Increasingly, workplace information seeking takes place in digital information environments and is reliant upon search systems.  ...  However, these three approaches to IR are not discrete, as the contextual approach represents an attempt to both integrate and extend the user-centred and system-centred approaches.  ...

Task-oriented Dialogue Systems: performance vs. quality-optima, a review [article]

Ryan Fellows, Hisham Ihshaish, Steve Battle, Ciaran Haines, Peter Mayhew, J. Ignacio Deza
2021 arXiv   pre-print
TODS typically have a primary design focus on completing the task at hand, so the metric of task-resolution should take priority.  ...  Task-oriented dialogue systems (TODS) are continuing to rise in popularity as various industries find ways to effectively harness their capabilities, saving both time and money.  ...  Authors would like to acknowledge the assistance provided by Mark Davis and his team in the initial discussions leading to this study and for their collaboration on the project.  ...

The evaluation of adaptive and personalised information retrieval systems: a review

Catherine Mulwa, Seamus Lawless, Mary Sharp, Vincent Wade
2011 International Journal of Knowledge and Web Intelligence  
Keywords: adaptive information retrieval systems; user-adaptive systems; user-centred evaluations; personalised information retrieval systems.  ...  However, evaluating an adaptive system is a difficult task due to the complexity of such systems. Evaluators need to ensure correct evaluation methods and measurement metrics are used.  ...  Acknowledgements This research is based upon works supported by Science Foundation Ireland (Grant Number: 07/CE/I1142) as part of the Centre for Next Generation Localization (  ...

How well do software assistants for minimally invasive partial nephrectomy meet surgeon information needs? A cognitive task analysis and literature review study

Fabian Joeres, Daniel Schindele, Maria Luz, Simon Blaschke, Nele Russwinkel, Martin Schostak, Christian Hansen, Simone Garzon
2019 PLoS ONE  
Within the user-centred development process of such systems, the first question to be asked is: What information does the surgeon need and when does he or she need it?  ...  In this article, we present an approach to investigate these surgeon information needs for minimally invasive partial nephrectomy and compare these needs to the relevant surgical computer assistance literature  ...  Acknowledgments We extend our sincere thanks to the nine senior urologists who volunteered their scarce time to participate in the interview study and who, thereby, made this research possible.  ...

Characterization and Prediction of Mobile Tasks

Yuan Tian, Ke Zhou, Dan Pelleg
2022 ACM Transactions on Information Systems  
Existing mobile systems handle mostly simple user needs, where a single app is taken as the unit of interaction.  ...  To provide a comprehensive picture of common mobile tasks, we first conduct a small-scale user study to understand annotated mobile tasks in-depth while we demonstrate that by using a set of features (  ...  [49] have validated that task information provides better context for IR systems to learn from.  ...
