An adaptive technique for content-based image retrieval

Jana Urban, Joemon M. Jose, Cornelis J. van Rijsbergen
2006 Multimedia tools and applications  
It is based on the Ostensive Model of developing information needs-a special kind of relevance feedback model that learns from implicit user feedback and adds a temporal notion to relevance.  ...  The ostensive approach supports content-assisted browsing through visualising the interaction by adding user-selected images to a browsing path, which ends with a set of system recommendations.  ...  Similar to the query representation in Equation 2, the new query is computed as the weighted (with the ostensive relevance weights) average of the path images in the OM.  ...

Interactive search in image retrieval: a survey

Bart Thomee, Michael S. Lew
2012 International Journal of Multimedia Information Retrieval  
In this article, we focus on the topic of contentbased image retrieval using interactive search techniques, i.e., how does one interactively find any kind of imagery from any source, regardless of whether  ...  We highlight trends and ideas from over 170 recent research papers aiming to capture the wide spectrum of paradigms and methods in interactive search, including its subarea relevance feedback.  ...  Open Access This article is distributed under the terms of the Creative Commons Attribution License which permits any use, distribution, and reproduction in any medium, provided the original author(s)  ...

A survey on the use of relevance feedback for information access systems

2003 Knowledge engineering review (Print)  
We also consider specific interfaces to relevance feedback systems and characteristics of searchers that can affect the use and success of relevance feedback systems.  ...  However, if the user can identify examples of the kind of documents they require then they can employ a technique known as relevance feedback.  ...  We would also like to acknowledge the helpful suggestions made by the anonymous reviewer.  ...

Supply management capabilities, routine bundles and their impact on firm performance

Marc Day, Scott Lichtenstein, Phillip Samouel
2015 International Journal of Production Economics  
The routines-based approach allows us to demonstrate a different, more fine-grained approach for assessing consistent bundles of homogeneous patterns of activity across firms.  ...  Using structural equation modelling we measure supply management capability empirically as a second-order latent variable and estimate its effect on a series of financial and operational performance measures  ...  We then review and discuss the results of questionnaire survey research to test the model using structural equation modelling.  ...

Effects of Usage-Based Feedback on Video Retrieval

David Vallet, Frank Hopfgartner, Joemon M. Jose, Pablo Castells
2011 ACM Transactions on Information Systems  
Our model is designed to capture the complex interactions of a user with an interactive video retrieval system, including the representation of sequences of user-system interaction during a search session  ...  In addition, there is a more comprehensive evaluation, with an extended test bed and the investigation on the effect of the quality and quantity of the available usage information.  ...  The best performing variations of both the query and the document neighbourhood approaches are using the overall relevance re-ranking and the ostensive model approach.  ...

2012 International Journal of Multimedia Information Retrieval  
In our evaluation participants were given a number of video search tasks and were asked to find relevant videos using two different interfaces: the first interface required users to use background knowledge  ...  However, it was also found that the perceptions of novice users, even with additional background knowledge, of the tools, collection and performance do not always match that of the expert users.  ...  Candidate images for browsing are determined by an ostensive model, which encompasses a temporal profile of uncertainty.  ...
