Creating temporally dynamic web search snippets

Krysta M. Svore, Jaime Teevan, Susan T. Dumais, Anagha Kulkarni
2012 Proceedings of the 35th international ACM SIGIR conference on Research and development in information retrieval - SIGIR '12  
Content on the Internet is always changing. We explore the value of biasing search result snippets towards new webpage content.  ...  Our results indicate that searchers prefer the inclusion of temporal information for trending queries but not for general queries, and that this is particularly valuable for pages that have not been recently  ...  INTRODUCTION Web content change often drives people to visit webpages to see what is new. For example, people visit news sites, blogs, and social media sites to stay up-to-date.  ...

What Is Usual in Unusual Videos? Trajectory Snippet Histograms for Discovering Unusualness

Ahmet Iscen, Anil Armagan, Pinar Duygulu
2014 2014 IEEE Conference on Computer Vision and Pattern Recognition Workshops  
In this study, we address the problem from the other side, and try to answer what type of patterns are shared among unusual videos that make them resemble to each other regardless of the ongoing event.  ...  Discovery of unusual events in videos is generally attacked as a problem of finding usual patterns, and then separating the ones that do not resemble to those.  ...  Acknowledgments This paper is partially supported by TUBITAK grant number 112E174.This paper was also partially supported by the US Department of Defense, the U.

Disambiguating Implicit Temporal Queries by Clustering Top Relevant Dates in Web Snippets

Ricardo Campos, Alipio Mario Jorge, Gael Dias, Celia Nunes
2012 2012 IEEE/WIC/ACM International Conferences on Web Intelligence and Intelligent Agent Technology  
With the growing popularity of research in Temporal Information Retrieval (T-IR), a large amount of temporal data is ready to be exploited.  ...  We used several measures for evaluating the performance of the system and compared our approach with Carrot Web-snippet clustering engine. Both experiments were complemented with a user survey.  ...  It is also supported by the Center of Mathematics, University of Beira Interior, project PEst-OE/MAT/UI0212/2011. We would also like to thanks the human annotators for their hard work.  ...

Caching query-biased snippets for efficient retrieval

Diego Ceccarelli, Claudio Lucchese, Salvatore Orlando, Raffaele Perego, Fabrizio Silvestri
2011 Proceedings of the 14th International Conference on Extending Database Technology - EDBT/ICDT '11  
Web Search Engines' result pages contain references to the top-k documents relevant for the query submitted by a user. Each document is represented by a title, a snippet and a URL.  ...  The snippet generation process is very expensive, since it may require to access a number of documents for each issued query.  ...  Acknowledgements This work was supported by the EU-FP7-250527 (Assets) project.  ...

Multimodal Reranking of Content-based Recommendations for Hyperlinking Video Snippets

Chidansh Bhatt, Nikolaos Pappas, Maryam Habibi, Andrei Popescu-Belis
2014 Proceedings of International Conference on Multimedia Retrieval - ICMR '14  
In this paper, we present an approach for topic-level search and hyperlinking of video snippets, which relies on contentbased recommendation and multimodal re-ranking techniques.  ...  Moreover, by analyzing the effect of multimodal re-ranking on hyperlinking performance, we emphasize the merits of rich visual information available in the anchors for the hyperlinking task, and the merits  ...  This work was supported by the Swiss National Science Foundation (AROLES project n. 51NF40-144627) and by the European Union (inEvent project FP7-ICT n. 287872).  ...

A Method for Visualizing Multivariate Time Series Data

Roger D. Peng
2008 Journal of Statistical Software  
Visualization and exploratory analysis is an important part of any data analysis and is made more challenging when the data are voluminous and high-dimensional.  ...  We outline the basic design concepts and provide some examples of its usage by applying it to a database of ambient air pollution measurements in the United States and to a hypothetical portfolio of stocks  ...  For example, we may want to know what the empirical distribution of values in a given time series looks like or what is the average trend across all time series.  ...

Analysis of Archaeological Phases Using the R Package ArchaeoPhases

Anne Philippe, Marie-Anne Vibet
2020 Journal of Statistical Software  
We propose new statistical tools to analyze and to estimate the characteristics of time periods based on the posterior distribution of an associated collection of dates.  ...  These tools are implemented in the R package ArchaeoPhases. The required inputs are simulated samples from the posterior distribution of a collection of dates.  ...  Acknowledgments The authors are most grateful to the editorial team and the referees for their relevant comments and useful suggestions, which helped us improve this article.  ...

In this paper, we present an approach to identify top relevant dates in Web snippets with respect to a given implicit temporal query. Our approach is two-fold.  ...  We evaluate both strategies over a set of real-world text queries and compare the performance of our Web snippet approach with a query log approach over the same set of queries.  ...  Specifically, is defined as the set of most relevant words/multi-words associated with a Web snippet and as the set of candidate years associated to a Web snippet .  ...

Ricardo Campos, Gaël Dias, Alípio Jorge, Célia Nunes
2016 Information Processing & Management  
Inferring the different temporal intents of this type of query enhances the overall temporal part of the web search results.  ...  Our approach relies on a novel temporal similarity measure that is capable of determining the most important dates for a query, while filtering out the non-relevant ones.  ...  Acknowledgments The authors want to thank the participants of the user study.  ...

A Hybrid Context Based Approach for Web Information Retrieval

W. Aisha Banu, P. Sheikh Abdul Kader
2010 International Journal of Computer Applications  
Information retrieval mechanisms from the web are a great need of the hour as the amount of the content is growing dynamically every day.  ...  These algorithms are either content based or snippet based and perform a clustered outcome re-ranking of the content for the user.  ...  The content trees now give the user an overview of what the snippets contain and is a concept map of the content. The key to the overall process is that the context of users is temporal and periodic.  ...
