Automatic Summarization on Aggregated Search Results

Rohit ArvindChakrapani, Rakesh Balabantaray, Pallavi Verulkar
2015 International Journal of Computer Applications  
However these results are mainly in the form of hyperlinks. As a result, the user has to go through each link to find and organize its relevant and focused data.  ...  Aggregated search is the task of integrating results from potentially multiple specialized search services, or verticals (images, videos, news, weather-forecasts, etc), into the web search results.  ...  Research into abstractive methods is an increasingly important and active research area, however due to complexity constraints; research to date has focused primarily on extractive methods.  ...

Focused and aggregated search: a perspective from natural language generation

Cécile Paris, Stephen Wan, Paul Thomas
2010 Information retrieval (Boston)  
With current technology, the burden of issuing these individual queries, analysing retrieved documents for relevance, as well as aggregating results falls upon the time-poor and informationally overloaded  ...  However, the way in which different data types are combined in current aggregated search applications is often performed using static hard-coded structures.  ...  Acknowledgements We thank Ross Wilkinson, Mounia Lalmas, Alexander Krumpholz, Nathalie Colineau, Andrew Lampert, and Tom Rowlands for discussions and useful input.  ...

Aggregated Search

Jaime Arguello
2017 Foundations and Trends in Information Retrieval  
Chapter 4 focuses on evaluation methodologies and metrics for aggregated search. Evaluation is a critical component of all information retrieval techniques and a research area in its own right.  ...  To date, most research in aggregated search has focused on the web search domain. For this reason, most of the research reviewed in this article will also focus on the web search domain.  ...

The Return of the Probability of Relevance

Norbert Fuhr
2013 Dutch-Belgian Workshop on Information Retrieval  
Most research on probabilistic models has focused only on producing a probabilistic ranking, without estimating the actual probabilities.  ...  The probability ranking principle (PRP) proves that ranking documents by decreasing probability of relevance yields optimum retrieval quality.  ...  His current research interests are retrieval models, networked digital library architectures, user-oriented retrieval methods and the evaluation of digital libraries.  ...

Query portals

Sanjay Agrawal, Kaushik Chakrabarti, Surajit Chaudhuri, Venkatesh Ganti, Arnd Christian König, Dong Xin
2010 Proceedings of the 2010 international conference on Management of data - SIGMOD '10  
Current federated approaches have two limitations: (i) they often fail to return important results for a broad class of such entity-oriented queries and (ii) the information they return per entity is often  ...  Web search engines federate such entity-oriented queries to relevant structured databases; the results of those searches are then returned to the user along with web search results.  ...  Entity Aggregation and Ranking: This component ranks the set of all entities returned by the entity retrieval component and surfaces the top few entities to the user.  ...

Deriving Locational Reference through Implicit Information Retrieval

Thomas Hervey, Werner Kuhn
2016 International Conference on GIScience Short Paper Proceedings  
The often fragmented process of online spatial data retrieval remains a barrier to domain scientists interested in spatial analysis.  ...  In an attempt to broaden the spectrum of exploitable spatial data sources, this paper proposes an extensible, locational reference deriving model that shifts extraction and encoding logic from the user  ...  However, as the numerous research challenges associated with GIR (geographic information retrieval) suggest (Jones and Purves 2008: 219) , current methods do not provide adequate solutions to navigate  ...
