The effectiveness of query-specific hierarchic clustering in information retrieval
2002
Information Processing & Management
Preserved Fulltext
In this paper we take the view that if hierarchic clustering is applied to search results (query-specific clustering), then it has the potential to increase the retrieval effectiveness compared both to ...
Hierarchic document clustering has been widely applied to information retrieval (IR) on the grounds of its potential improved effectiveness over inverted file search (IFS). ...
Acknowledgements The authors would like to thank Ian Ruthven and Dr. Iain Campbell for their comments on earlier drafts of this paper, and the anonymous reviewers for their helpful suggestions. ...

To address this issue, the possibilities of using Local Cluster Analysis as a preliminary framework with the intention of improving the effectiveness of weak queries by clustering search results and creating ...
In a web retrieval task, the query is usually short and the users expect to find the relevant documents in the first several result pages. ...
The actual effectiveness of hierarchic clustering can be gauged by Cluster-based retrieval strategies, which perform a ranking of clusters instead of individual documents in response to each query 22, ...

Next, the retrieved images are analyzed using hierarchical agglomerative clustering methods (HACM) and the rank of the results is adjusted according to the distance of a cluster from a query. ...
In addition, we analyze the effects of clustering methods, querycluster similarity functions, and weighting factors in the proposed method. ...
So, most of the research on cluster analysis in information retrieval has employed hierarchical methods. Hierarchical clustering methods can be classified into two kinds: agglomerative and divisive. ...
