Automatic text structuring and retrieval-experiments in automatic encyclopedia searching

Gerard Salton, Chris Buckley
1991 Proceedings of the 14th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '91  
The methods are illustrated by search experiments performed with the 29-volume Funk and Wagnalls encyclopedia.  ...  Many conventional approaches to text analysis and information retrieval prove ineffective when large text collections must be processed in heterogeneous subject areas.  ...  It is widely believed that the keyword approach is not adequate for text content representation in infor- mation retrieval.  ...

Large-Scale Cross-Media Retrieval of WikipediaMM Images with Textual and Visual Query Expansion [chapter]

Zhi Zhou, Yonghong Tian, Yuanning Li, Tiejun Huang, Wen Gao
2009 Lecture Notes in Computer Science  
We first experimented with a text-based image retrieval approach with query expansion, where the extension terms were automatically selected from a knowledge base that was semi-automatically constructed  ...  Though not submitted, this approach outperforms our text-based and content-based approaches remarkably.  ...  Experiments with Cross-Media Retrieval In the last set of experiments, cross-media retrieval approach is used to achieve better performance by combining text-based and content-based retrieval results.  ...

Inferring Geographical Ontologies from Multiple Resources for Geographical Information Retrieval

Davide Buscaldi, Paolo Rosso, Piedachu Peris
2006 Workshop on Geographic Information Retrieval  
The use of resources like gazetteers and geographical ontologies can improve the results in Geographical Information Retrieval.  ...  Unfortunately, the construction of such ontologies is a long and laborious process; therefore, building an ontology in a semi-automatical way exploiting multiple sources is an interesting and useful task  ...  needs arisen from our previous experience in the use of WordNet for the GeoCLEF task.  ...
