Information retrieval in context

Peter Ingwersen, Kalervo Järvelin
2005 SIGIR Forum  
Thus truly context-aware and -dependent retrieval will become feasible. Information retrieval in context can mean one of two things.  ...  The retrieval of such information will depend on time, place, history of interaction, task in hand, and a range of other factors that are not given explicitly but are implicit in the interaction and ambient  ...  How can features of context be used to improve information retrieval? a. We need to develop methods of investigation, test beds, evaluation measures and techniques b.  ...

Using query contexts in information retrieval

Jing Bai, Jian-Yun Nie, Guihong Cao, Hugues Bouchard
2007 Proceedings of the 30th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '07  
Our experiments on several TREC collections show that each of the context factors brings significant improvements in retrieval effectiveness.  ...  In this paper, both types of context are integrated in an IR model based on language modeling.  ...  We argue that the problem stems from the lack of necessary context information in relations themselves, and a more radical solution lies in the addition of contexts in relations.  ...

Using physical context for just-in-time information retrieval

B. Rhodes
2003 IEEE transactions on computers  
This paper describes an experiment that evaluates the usefulness of the wearer's physical context (location and people in the area) for automatically finding useful archived information.  ...  The results suggest that, while physical context can be used to discover useful archived notes, the subject and text of notes currently being entered are a much better indicator of usefulness in the personal  ...  INTRODUCTION A Just-in-time Information Retrieval (JITIR) agent is software that proactively retrieves and presents information based on a person's local context.  ...
