External Query Expansion in the Blogosphere
2008
Text Retrieval Conference
Preserved Fulltext
In the blog distillation task we tried to improve over our (strong) baseline using external expansion, but due to differences in the run setup, comparing these runs is hard. ...
We describe the participation of the University of Amsterdam's ILPS group in the blog track at TREC 2008. We mainly explored different ways of using external corpora to expand the original query. ...
Acknowledgments This research was supported by the DuOMAn project carried out within the STEVIN programme which is funded by the Dutch and Flemish Governments (http://www. stevin-tst.org) under project ...

Query Expansion (QE) often improves the retrieval performance of an Information Retrieval (IR) system. ...
In this paper, we propose the use of query performance predictors to selectively apply CE on a per-query basis. ...
In the future, we plan to deploy our proposed method for blog search as collections from the blogosphere contain many spam documents and other noisy vocabulary, meaning that query expansion might benefit ...

In this paper, we describe research conducted to help inform digital curation of on-line video. ...
These query expansions represent differences in how the Blogosphere and YouTube data sets were collected and are a result of the data collection efforts starting independently. ...

The nature of the Blogosphere determines that the majority of bloggers are only connected with a small number of fellow bloggers, and similar bloggers can be largely disconnected from each other. ...
In this work, we define the problem, delineate its challenges, and present an approach that uses innovative ways to employ contextual information and collective wisdom to aggregate similar bloggers. ...
CONCLUSIONS The sparsely linked blogosphere presents a new problem -searching for similar bloggers in the long tail of Blogosphere, in order to discover and connect niches in the long tail where the majority ...

In this article we propose a general generative query expansion model that uses external document collections for term generation: the External Expansion Model (EEM). ...
The main rationale behind our model is our hypothesis that each query requires its own mixture of external collections for expansion and that an expansion model should account for this. ...
ACKNOWLEDGMENTS We are grateful to our reviewers and the editors of the journal for providing valuable comments and feedback, helping us to improve the quality of this article. ...

Finding opinionated blog posts is still an open problem in information retrieval, as exemplified by the recent TREC blog tracks. ...
Our approach is inspired by the Divergence From Randomness (DFR) query expansion mechanism, which measures the divergence of a term's distribution in a pseudo-relevance set from its distribution in the ...
