On the construction of effective vocabularies for information retrieval
1973
Proceedings of the 1973 meeting on Programming languages and information retrieval - SIGPLAN '73
Preserved Fulltext
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.

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. ...
