DeShaTo: Describing the Shape of Cumulative Topic Distributions to Rank Retrieval Systems Without Relevance Judgments [chapter]

Radu Tudor Ionescu, Adrian-Gabriel Chifu, Josiane Mothe
2015 Lecture Notes in Computer Science  
Then, for a retrieved set of documents, a set of probability distribution shape descriptors, namely the skewness and the kurtosis, are used to compute a score based on the shape of the cumulative topic  ...  In this work, DeShaTo is used to rank retrieval systems without relevance judgments. In most cases, the empirical results are better than the state of the art approach.  ...  Web Track 2013 and 2014 have considerably less participants than Robust, and the nruns approach is less accurate on the Web Track 2013 and 2014 data sets.  ...

Adversarial content manipulation effects

Fiana Raiber
2012 Proceedings of the 35th international ACM SIGIR conference on Research and development in information retrieval - SIGIR '12  
We address a question that has been somewhat overlooked throughout the transition from classical ad hoc retrieval to Web search: how is the performance of classical retrieval approaches affected by the  ...  A natural future venue to explore is how to mix these strategies and make (some of) them more robust under presumed content manipulation conditions.  ...  INTRODUCTION Classical ad hoc (query-based) retrieval approaches focus on the document content for determining relevance to queries.  ...

Enhancing Keyword Query Results Over Database for Improving User Satisfaction

Priya Pujari, Roshani Ade
2016 International Journal of Managing Public Sector Information and Communication Technologies  
Here an inTeractive Retrieving-Inferring data imputation method (TRIP) is used which achieves retrieving and inferring alternately to fill the missing attribute values in the database.  ...  Storing data in relational databases is widely increasing to support keyword queries but search results does not gives effective answers to keyword query and hence it is inflexible from user perspective  ...  ACKNOWLEDGEMENTS The authors would like to thank all the members for their expert guidance and all others who directly or indirectly helped and made numerous suggestions which improved the quality of this  ...

Webly Supervised Joint Embedding for Cross-Modal Image-Text Retrieval [article]

Niluthpol Chowdhury Mithun, Rameswar Panda, Evangelos E. Papalexakis, Amit K. Roy-Chowdhury
2018 arXiv   pre-print
We propose a two-stage approach for the task that can augment a typical supervised pair-wise ranking loss based formulation with weakly-annotated web images to learn a more robust visual-semantic embedding  ...  Experiments on two standard benchmark datasets demonstrate that our method achieves a significant performance gain in image-text retrieval compared to state-of-the-art approaches.  ...  This work was partially supported by NSF grants IIS-1746031 and CNS-1544969. We thank Sujoy Paul for helpful suggestions and Victor Hill for setting up the computing infrastructure used in this work.  ...

Composite retrieval of heterogeneous web search

Horatiu Bota, Ke Zhou, Joemon M. Jose, Mounia Lalmas
2014 Proceedings of the 23rd international conference on World wide web - WWW '14  
In this paper, we propose and evaluate a variety of approaches to construct bundles that are relevant, cohesive and diverse.  ...  For instance, many such search engines return to users both images and web documents as answers to the query "flower". Aggregated search has become a very popular paradigm.  ...  Robustness To answer RQ5, we varied the initial rankings that composite retrieval approaches are based on and investigated the robustness of different composite retrieval approaches.  ...

Robust Models in Information Retrieval

Nedim Lipka, Benno Stein
2011 2011 22nd International Workshop on Database and Expert Systems Applications  
We present two case studies: (1) a categorization task, which demonstrates that robust models are more stable in retrieval situations when training data is scarce, and (2) a genre identification task,  ...  Classification tasks in information retrieval deal with document collections of enormous size, which makes the ratio between the document set underlying the learning process and the set of unseen documents  ...  A Robust Genre Retrieval Model For our robust genre retrieval model we introduce the features "Maximum Term Concentration" and "Gini Coefficient" based on genre-specific core vocabularies and concentration  ...

Supporting end-users in the creation of dependable web clips

Sandeep Lingam, Sebastian Elbaum
2007 Proceedings of the 16th international conference on World Wide Web - WWW '07  
The support consists of a mechanism to identify the target clipping with multiple markers to increase robustness, and a dynamic assessment of the retrieved information to quantify its reliability.  ...  The clipping approach has been integrated as a feature into a popular web authoring tool on which we present the results of two preliminary studies.  ...  Acknowledgments This work was supported in part by NSF CAREER Award 0347518 and the EUSES Consortium through NSF-ITR 0324861.  ...
