A distributed digital text accessing and acquisition system

Abstract

BiblioDigital ® is a network of reservoirs (R) of text documents. Each document exists primarily in one R, with possible duplicates in other Rs. Each R sits in its own server. Each document in indexed in three ways: * by themes (vocabulary controlled by that R's librarian); * by each word in the document, * by the concepts which the document covers (using Clasitex ®). Each R contains the global index (of all Rs), so that each R can provide the following services: * browsing by themes; * by concepts;' * by words; * by metadata; * by Boolean combination of above. Also, BiblioDigital * allows subscription to a personal News Services: through a user interest profile; * BiblioDigital combs the Web for documents that could fall in the themes or topics contained in its indices, and indexes them, thus enriching its knowledge content. © Springer-Verlag 2004.
