In this paper, we introduce the notion of ranking robustness, which refers to a property of a ranked list of documents that indicates how stable the ranking is in the presence of uncertainty in the ranked ...
We demonstrate that the robustness score significantly and consistently correlates with query performance in a variety of TREC test collections including the GOV2 collection. ...

Relabeling algorithm for retrieval of noisy instances and improving prediction quality
2010
Computers in Biology and Medicine
A relabeling algorithm for retrieval of noisy instances with binary outcomes is presented. ...
The relabeling algorithm iteratively retrieves, selects, and re-labels data instances (i.e., transforms a decision space) to improve prediction quality. ...
The approaches for retrieval of mislabeled instances presented in the literature generally use majority/consensus (allowing presence of impurity) filters to isolate stable and noisy instances. ...

Term Proximity Constraints for Pseudo-Relevance Feedback
2017
Proceedings of the 40th International ACM SIGIR Conference on Research and Development in Information Retrieval - SIGIR '17
Pseudo-relevance feedback (PRF) refers to a query expansion strategy based on top-retrieved documents, which has been shown to be highly e ective in many retrieval models. ...
Experiments on four TREC collections demonstrate the e ectiveness of the proposed constraints. Our modi cation to the log-logistic model leads to signi cant and substantial (up to 15%) improvements. ...

Distributed Evaluations: Ending Neural Point Metrics
[article]
2018
arXiv
pre-print
As neural methods are starting to be incorporated into low resource and noisy collections that further exacerbate this issue, we propose evaluating neural models both over multiple random seeds and a set ...
However, these networks often sample data in random order, are initialized randomly, and their success is determined by a single evaluation score. ...

Axiomatic Analysis for Improving the Log-Logistic Feedback Model
2016
Proceedings of the 39th International ACM SIGIR conference on Research and Development in Information Retrieval - SIGIR '16
Pseudo-relevance feedback (PRF) has been proven to be an effective query expansion strategy to improve retrieval performance. Several PRF methods have so far been proposed for many retrieval models. ...
Experiments on three TREC newswire and web collections demonstrate that the proposed modification significantly outperforms the original log-logistic model, in all collections. ...
This observation demonstrates that the log-logistic model is less effective and robust in improving the retrieval performance in the web collection, compared to the newswire collections. ...

Learning actions from the Web
2009
2009 IEEE 12th International Conference on Computer Vision
Its benefits are two-fold: 1) we can improve retrieval of action images, and 2) we can collect a large generic database of action poses, which can then be used in tagging videos. ...
The idea is to use images collected from the Web to learn representations of actions and use this knowledge to automatically annotate actions in videos. ...
