Opinionated document retrieval using subjective triggers

Kazuhiro Seki, Kuniaki Uehara
2011 Journal of the American Society for Information Science and Technology  
Experimental results on the TREC Blog track test collections show that, when used for reranking initial search results, our proposed model significantly improves opinionated document retrieval.  ...  One is the subject of the opinion or the object that the opinion is about, and the other is a subjective expression; the former is regarded as a triggering word and the latter as a triggered word.  ...  Opinion Retrieval by a Trigger Model Motivation To judge whether a given document contains subjective opinions, the simplest and most intuitive approach would be to look for subjective words in the document  ...

A Comparative Study of Open Domain and Opinion Question Answering Systems for Factual and Opinionated Queries

Alexandra Balahur, Ester Boldrini, Andrés Montoyo, Patricio Martínez-Barco
2009 Recent Advances in Natural Language Processing  
A collection of opinion and mixed fact-opinion questions in English is defined and two Question Answering systems are employed to retrieve the answers to these queries.  ...  The increasing number of such texts and the highly diverse topics they discuss make blogs a rich source for analysis. This paper presents a comparative study on open domain and opinion QA systems.  ...  Acknowledgments The authors would like to thank Paloma Moreda, Hector Llorens, Estela Saquete and Manuel Palomar for evaluating the questions on their QA system.  ...

An experimental evaluation of ontology-based user profiles

Frank Hopfgartner, Joemon M. Jose
2012 Multimedia tools and applications  
In recent years, a number of research works have been carried out to improve the information retrieval process by exploiting external knowledge, e.g., by employing ontologies.  ...  Even though ontologies seem to be a promising technique to improve the retrieval process, hardly any study has been performed to evaluate the use of ontologies over a longer time period to model user interests  ...  In the next section the challenges in the evaluation of interactive and adaptive retrieval systems are outlined.  ...
