On the construction of effective vocabularies for information retrieval

G. Salton, Clement T. Yu
1973 Proceedings of the 1973 meeting on Programming languages and information retrieval - SIGPLAN '73  
The construction of "good" natural language vocabularies is then described, and methods are given for improving the vocabulary by transforming terms that operate poorly for retrieval purposes into better  ...  The usefulness of the terms in a natural language vocabulary is first characterized in terms of their frequency distribution over the documents of a collection.  ...  An approach to the construction of effective natural language vocabularies is outlined in the next few paragraphs. II.  ...

Supporting the process of satisfying information needs with reusable software libraries

Scott Henninger
1995 Proceedings of the 1995 Symposium on Software reusability - SSR '95  
Retrieval tools for component-based software reuse libraries face two interrelated problems. The first is the ill-defined nature of information needs.  ...  The study confirmed the utility of spreading activation and retrieval by reformulation techniques for satisfying information needs of the kind encountered in software design.  ...  There was a strong effect for the number of queries submitted on matching tasks between CodeFinder and DEx (F( 1, 22)=24.64, p=.0001).  ...

Iterative Random Visual Word Selection

Thierry Urruty, Syntyche Gbèhounou, Huu Ton Le, Jean Martinet, Christine Fernandez
2014 Proceedings of International Conference on Multimedia Retrieval - ICMR '14  
In content based image retrieval, one of the most important step is the construction of image signatures. To do so, a part of state-of-the-art approaches propose to build a visual vocabulary.  ...  In this paper, we propose a new methodology for visual vocabulary construction that obtains high retrieval results.  ...  Therefore the proposed easy and fast vocabulary construction for any visual features may replace the BoV W construction stage without losing in retrieval effectiveness.  ...

Improving Bag of Visual Words Image Retrieval: A Fuzzy Weighting Scheme for Efficient Indexation

Wassim Bouachir, Mustapha Kardouchi, Nabil Belacel
2009 2009 Fifth International Conference on Signal Image Technology and Internet Based Systems  
Recent works on Content Based Image Retrieval rely on bag of visual words to index visual content.  ...  Instead of using the known weighting schemes directly migrated from text retrieval domain, we propose a new approach specifically for images.  ...  Building a visual vocabulary The construction of the visual vocabulary is an important step of the BoVW model.  ...

From Authority Control to Informed Retrieval: Framing the Expanded Domain of Subject Access

Prudence W. Dalrymple, Jennifer A. Younger
1991 College and Research Libraries  
Methods of facilitating subject access are categorized as end points on a continuum: authority control, controlling the results of indexing, and informed retrieval-informing the process of searching.  ...  The purpose of this article is to propose a broader framework within which to analyze barriers to effective subject access and to propose directions for research and action.  ...  One of the most challenging issues in electronic information retrieval (CD-ROM, online catalogs, and online information retrieval systems) is providing effective subject access to users.  ...
