Abstract

In the context of information retrieval, we propose here to merge in a single mathematical framework: the Boolean model, the vector space model, and passage retrieval in a single mathematical framework based on signal theory. In this framework, we define the weight wd,t of the term t in the document d not as a number, but as a function.
