Facet-based opinion retrieval from blogs

Olga Vechtomova
2010 Information Processing & Management  
The paper presents methods of retrieving blog posts containing opinions about an entity expressed in the query.  ...  Methods of structuring queries into facets, facet expansion using Wikipedia, and a facet-based retrieval are also investigated in this work.  ...  While the general idea of faceted retrieval is not new, the paper proposes a novel method of facet identification in the query, expansion of each facet by means of Wikipedia, and use of facets in opinion  ...

Facet Classification of Blogs: Know-Center at the TREC 2009 Blog Distillation Task

Elisabeth Lex, Michael Granitzer, Andreas Juffinger
2009 Text Retrieval Conference  
The facet identification based on our approach was successful, although a significant number of candidate blogs were not retrieved at all.  ...  In this paper, we outline our experiments carried out at the TREC 2009 Blog Distillation Task. Our system is based on a plain text index extracted from the XML feeds of the TREC Blogs08 dataset.  ...  The facet identification based on this approach was successful, although a significant number of candidate blogs were not retrieved at all.  ...

UIC at TREC 2010 Faceted Blog Distillation

Lifeng Jia, Clement T. Yu
2010 Text Retrieval Conference  
Our system consists of a concept-based retrieval subsystem which performs the baseline blog distillation, an opinion identification subsystem and an opinion-in-depth analysis subsystem which performs the  ...  faceted blog distillation task.  ...  Facet Feed Ranking Strategy A blog document is retrieved by the concept-based retrieval subsystem w.r.t. a query topic and then assigned a facet score w.r.t. the interested facet value.  ...

BIT at TREC 2009 Faceted Blog Distillation Task

Peng Jiang, Qing Yang, Chunxia Zhang, Zhendong Niu
2009 Text Retrieval Conference  
This Paper presents the work done for the TREC 2009 faceted blog distillation task of blog track. In our approach, we use a mixture of language models based on global representation.  ...  By pseudorelevance feedback method, we can estimate the above two models from topic relevance feedback documents and facet relevance feedback documents respectively.  ...  This work is supported by the grant from Chinese National Natural Science Foundation (No: 60705022).  ...

HIT_LTRC at TREC 2010 Blog Track: Faceted Blog Distillation

Jinfeng Yang, Xishuang Dong, Yi Guan, Chengzhen Huang, Sheng Wang
2010 Text Retrieval Conference  
This paper describes our participation in the faceted blog distillation task at Blog Track 2010. In our approach, indri toolkit is applied for basic topic relevance retrieval.  ...  Then the Maximum Entropy (ME) model is adopted to judge the relevance of each blog to specified facet.  ...  Based on these features, blogs' faceted inclination could be predicted, and blogs' faceted relevance can be calculated.  ...

RMIT at TREC 2010 Blog Track: Faceted Blog Distillation Task

Zhixin Zhou, Xiuzhen Zhang, Phil Vines
2010 Text Retrieval Conference  
For the personal versus official facet, we assumed blogs which are opinionated are also personal.  ...  For the baseline task, we adopted the BM25 model implemented in the Zettair search engine to establish a retrieval system of blog posts based on topic relevance.  ...  However, a blog consists of a number of posts, each of which is a single document. As such, document-based retrieval systems are usually not directly applicable to the blog distillation task.  ...

Blog track research at TREC

Craig Macdonald, Rodrygo L.T. Santos, Iadh Ounis, Ian Soboroff
2010 SIGIR Forum  
Since, its advent in TREC 2006, the Blog track has led to much research in this growing field, and encapsulated cross-pollination from natural language processing research.  ...  The TREC Blog track aims to explore information seeking behaviour in the blogosphere, by building reusable test collections for blog-related search tasks.  ...  We are also thankful to Gilad Mishne and Maarten de Rijke for joining us in organising the TREC 2006 Blog track.  ...

Facet-Driven Blog Feed Retrieval

Lifeng Jia, Clement T. Yu, Weiyi Meng, Lei Zhang
2013 International Journal of Computational Linguistics and Applications  
The faceted blog distillation task retrieves blogs (i.e. RSS feeds) that are not only relevant to a query but also satisfy an interested facet.  ...  For the opinionated/factual facets, we propose a classifier that uses syntactic and semantic features to determine whether an opinion in blog documents is relevant to a given query.  ...  Since opinion retrieval plays a central role in faceted blog distillation, we first evaluate our opinion-finding techniques using 100 TREC 2007-2008 queries over five TREC baselines (of documents) from  ...
