Employing document dependency in blog search

Mostafa Keikha, Fabio Crestani, Mark James Carman
2011 Journal of the American Society for Information Science and Technology  
The goal in blog search is to rank blogs according to their recurrent relevance to the topic of the query. State of the art approaches view it as an expert search or resource selection problem.  ...  We compare these methods with the state of the art approaches in blog search that employ Language Modeling based resource selection algorithms and fusion-based methods for aggregating post relevance scores  ...  Document Dependency in the Blogosphere None of the techniques described in previous section have taken the dependency between posts from different blogs into account when calculating query relevance scores  ...

Using computational community interest as an indicator for ranking

Xiaozhong Liu
2009 Proceedings of the 32nd international ACM SIGIR conference on Research and development in information retrieval - SIGIR '09  
Ranking documents in response to users' information needs is a challenging task, due, in part, to the dynamic nature of users' interests with respect to a query.  ...  The user-oriented data can be user blogs or user comment tagged news. Preliminary evaluation shows that the new ranking method significantly improves ranking performance.  ...  We hypothesize that the ranking score for each retrieved document in the search result should depend on current community interests.  ...

Finding a needle in the blogosphere: An information fusion approach for blog distillation search

José M. Chenlo, Javier Parapar, David E. Losada, José Santos
2015 Information Fusion  
In this paper we propose a group of textual and social-based signals, and apply different Information Fusion algorithms for a Blog Distillation Search task.  ...  In this context, the problem of finding a topically relevant blog to subscribe to becomes a Big Data challenge. Moreover, combining multiple types of evidence is essential for this search task.  ...  Here, we employ the Line Search procedure proposed by Taylor et al.  ...

Generalizing diversity detection in blog feed retrieval

Mostafa Keikha, Fabio Crestani, Bruce Croft
2013 Proceedings of the 22nd ACM international conference on Conference on information & knowledge management - CIKM '13  
The goal of a blog retrieval system is to retrieve and rank blogs, as collections of documents, in response to a given query.  ...  The proposed measure enables us to integrate diversity in any existing blog retrieval method.  ...  Researchers have employed different approaches from related areas such as ad-hoc search, expert search, and resource selection in distributed information retrieval.  ...

Blog track research at TREC

Craig Macdonald, Rodrygo L.T. Santos, Iadh Ounis, Ian Soboroff
2010 SIGIR Forum  
The TREC Blog track aims to explore information seeking behaviour in the blogosphere, by building reusable test collections for blog-related search tasks.  ...  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.  ...  We are also thankful to Gilad Mishne and Maarten de Rijke for joining us in organising the TREC 2006 Blog track.  ...

Time-based relevance models

Mostafa Keikha, Shima Gerani, Fabio Crestani
2011 Proceedings of the 34th international ACM SIGIR conference on Research and development in Information - SIGIR '11  
In this method, we select terms for expansion using most relevant days for the query, as opposed to most relevant documents. This provide us with more trustable terms for expansion.  ...  Our preliminary experiments on Blog08 collection shows that this method can outperform state of the art relevance feedback methods in blog retrieval.  ...  One of the open challenges in blog retrieval is relevance feedback and employing the most appropriate documents for query expansion.  ...

TEMPER: A Temporal Relevance Feedback Method [chapter]

Mostafa Keikha, Shima Gerani, Fabio Crestani
2011 Lecture Notes in Computer Science  
In this paper we investigate the effect of time dependency in query expansion.  ...  The goal of a blog distillation (blog feed search) method is to rank blogs according to their recurrent relevance to the query.  ...  Some other approaches have been applied from expert search methods in blog retrieval [8, 2] .  ...

BlogScope: A System for Online Analysis of High Volume Text Streams

Nilesh Bansal, Nick Koudas
2007 Very Large Data Bases Conference  
The system currently tracks over ten million blogs and handles hundreds of thousands of updates daily.  ...  Such features include, spatio-temporal analysis of blogs, flexible navigation of the Blogosphere through information bursts, keyword correlations and burst synopsis, as well as enhanced ranking functions  ...  In information theory, mutual information [3] is commonly used to measure the mutual dependence of the two variables. where P (t ∈ D) denotes the probability of token t appearing in some document D in  ...

OntoBlog: Linking Ontology and Blogs

Aman Shakya, Vilas Wuwongse, Hideaki Takeda, Ikki Ohmukai
2007 International Conference on Knowledge Capture  
Semantic navigation allows users to navigate through each blog entry to semantically related blog entries. Semantic search can be employed in blogs.  ...  OntoBlog is a prototype semantic blogging system which employs semi-automatic semantic annotation of blog entries using ontology instances.  ...  IE techniques have been employed for the recognition of named entities in documents. It also introduces indexing and retrieval based on named entities.  ...

Blog site search using resource selection

Jangwon Seo, W. Bruce Croft
2008 Proceeding of the 17th ACM conference on Information and knowledge mining - CIKM '08  
Blog site search is similar to resource selection in distributed information retrieval, in that the target is to find relevant collections of documents.  ...  A blog site consists of many individual blog postings. Current blog search services focus on retrieving postings but there is also a need to identify relevant blog sites.  ...  The choice of a sampling method depends on the goals of blog site search services.  ...
