In this paper, we describe a method to generate an information retrieval hypertext structure on a large collection of homogeneous documents by generating links only between noun phrases that are pertinent for navigation. Noun phrases are selected by automatic extraction and filtered on the basis of the linguistic context class where they appear, also determined automatically.
